Introspective ...Walking The Dogs

2009-07-10T17:13:00.008+01:00

Walking The Dogs
A shot taken at Felixstowe seafront of a couple walking their dogs
along the concert, with a stray child looking on. Winter 2008.

I was visiting Felixstowe on a day out while staying with friends in the last days of December, last year. I had my trusty 17-85mm zoom fitted, complete with hood because of the lighting conditions.

Because I was with two kids who were full of beans, I needed to keep my wits about me and be ready for when those few magic moments appeared. You know the sort, the ones where you think, "darn, if only I'd been ready with my camera!"

Composing and making the capture

Spotting the potential

Well the lighting was superb, picking out the eager faces of the beach huts and, with the curve of the coast leading the eye naturally to the main beach in the distance, there was plenty of potential. I just had to hope that someone would turn up to provide the subject for this wonderful backdrop.

Preparing for the shot

I noticed the steps coming down from the car park above, so positioned myself so that anyone approaching from that direction would walk into the scene from the right. I then composed so that the main beach was roughly in one of the rule-of-thirds power points.

I could see a couple coming down the steps to the front, and knew the final elements would soon be in place.

Exposure, ISO etc.

Lighting was fine, so there was no need to move from ISO 100. I always stick with aperture priority and f9 at the wide angle end of my zoom is enough to get everything in focus from my feet to infinity. Perfect for this shot. Because I was shooting into the sun (slightly out of frame to the left), the lens hood was essential to minimise lens flare.

I exposed for the sky (exposure lock — point at the sky, half press the shutter release and hold it, then recompose and finally press the release all the way). I fired off a couple of practice shots to check the histogram — I didn't want to blow those highlights.

As it turned out, on the first practice shot I did, so I re-exposed, making sure I was on the brightest part of the sky this time for the exposure lock. Yep, the histogram was showing all was well. I was ready. Shutter speed was 1/250 by the way.

Oh, and as I always shoot in RAW, I knew I'd have some leeway with the exposure, should lighting conditions change between taking the final exposure lock and waiting for the scene to be filled with a subject.

The capture

I was ready and, on cue, the couple entered the scene — with dogs, too! Got lucky with my subjects there :)

The child on the upper concert was a further bonus, adding to the story. I think he'd raced ahead of mum and dad, who were still coming down the steps.

And then I was off for the next shot (Caught By The Surf, if you were curious — and, wow, two in a row were keepers!)

Digital darkroom

Rawshooter Essentials

The first part of my workflow is done in Rawshooter. I initially sort out the keepers from the maybes and the definite binners.

For each keeper, I then make any slight exposure and any initial contrast adjustments before converting to 16bit TIFF, ready to move into PhotoShop.

For this one, the exposure was ok as taken, and needed just a tad of fill light before the TIFF conversion.

PhotoShop

Again, fairly standard for my workflow, I applied a bit of
TLR capture sharpening first, converted to mono using the black and white filter and judicial use of the channel sliders.

While adjusting the sliders, I kept an eye on the interplay between sky and ground but couldn't quite achieve a conversion that convinced me. I ended up treating the sky with a gradient fill to tone it down a little.

I did a little dodging and burning to the rightmost beach hut and applied a slight double vignette to bring the eye's attention to the couple and their implied destination.

I applied my usual final tweak on the curves to increase the contrast and added a slight adjustment to the levels to deepen the shadows and lift the highlights a bit and that was it.

A final bit of sharpening and size reduction as I saved as a jpeg, and it was ready for upload.

Artwork I've sold

2009-07-10T12:41:00.003+01:00

I've had a few private emails from followers and others asking about any sales I've made of my artwork.

If you're also interested, you can see them all, since I started keeping records, by following this site-search (from my main site).

More copies of your name go in the hat for each review / rating, recommendation and comment you leave / have left during June.

I suggest you find your favourite images in the galleries on my main web site:

..and review or recommend them. That way, if you win, I know which ones you like and can make sure you get one of those as your prize - a mounted, signed print, ready to frame.

The Kingsize Five cont'd...

2009-06-30T13:29:00.004+01:00

Continuing with the pile, this is the last shot I got of the band.

Singers

I wanted to capture some of the exuberance and energy they displayed on stage and hopefully that's what I managed. The blurry hands of the girls work well for this, but the bloke was moving right-to-left just too quickly to freeze his features.

Maybe next time I'll remember to set the drive mode to continuous shooting to stand more of a chance in getting the shot that works best.

Comments / hints / tips gratefully received

Going through a bunch of unprocessed photos

2009-06-29T15:51:00.006+01:00

I've been going through the pile of unprocessed photos in my digital darkroom. You know, the pile that builds up of the ones that haven't yet inspired you — while more recent ones have and have been dealt with.

Always a danger when you're doing this, though, that your "that's worthy" filter gets fooled — and I think mine has here! ;)

What do you think? More worthy for the recycle bin or...

Barbican Jazz and Blues Festival

This one came from a brief shoot at the Barbican International Jazz and Blues Festival and shows (some of!) the Kingsize Five brass section.

This was the closing session and marked the end of a great ten days of jazz and blues music from all round the world.

Holy Trinity Church - last from the digital darkroom

2009-06-24T15:39:00.004+01:00

This is the last of the shots taken at Holy Trinity Church, Buckfastleigh, Devon.

Eternal Reflection

In this shot, given that it's all about a church and cemetery, I wanted to include an obvious religious icon and turn the viewer's thoughts to reflection on their own mortality.

When all is said and done and your life has run its course, what will your legacy be—other than bones and a tombstone?

As always, comments / thoughts / critiques welcome :)

Buckfastleigh shoot—a few more photos

2009-06-18T12:30:00.010+01:00

Here's the next batch out of the digital darkroom from my recent visit to Buckfastleigh, and a continuation of the bones story.

Holy Trinity Church and cemetery

The grave of Thomas and Polly Elizabeth Luckraft on the north side of the church, surrounded by so many weathered and barely readable headstones. I thought the overhanging leaves, as well as helping with the framing, would give a feeling of intrusion into this other-worldly place of rest.

In this shot, I wanted to show the church in context. At the same time, I was hoping to be able to capture something of the former imposing nature of the church, and the fact that today, in ruin, it's rather impotent—almost a metaphor for the decline in the reach of the church in the present-day UK.

After the vandal-started fire that destroyed it, the church has been made safe and services are still held here from time to time. It's strange that without all the trappings of religious dogma, to me it still feels like a holy place, perhaps even more so.

Hopefully, I've captured something of that atmosphere in this shot.

Dem Bones, dem bones...

After a comment on my last post, asking about the finish to the caving dig story...

A bit of background first: A cave close by, called "Joint Mitnor", houses a talus cone (pile of rubble and dirt that fell from above, to you and me) that contains the bones (not fossilised) of bear, elephant, bison, hippopotamus, hyena, rhinocerous, lion... you get the picture. And, remember, this is the UK! [more here]

Bakers Pit, the dig

Ok, so as I said in my last post, we were on a dig in Bakers Pit, part of the same system as Joint Mitnor. The dig was drawn out over a period of around 18 months, visiting every couple of months or so. We'd reached a promising chamber that had what looked like part of a continuation passage, leading up and away at the top of a slope of rich, earthy mud and occasional rocks.

Revealing the way forward

Our approach to the dig in this chamber was to shift the mud and rocks at the bottom of the slope and let gravity do the rest. Then on our next visit we'd repeat the process. And this we did for four or five visits. On our second to last visit, a promising way forward was found at the top of the slope ...but it was all very precarious, and the walls / bedrock wasn't yet exposed.

The bone

And then I found the bone, vertebrae of maybe a deer or something, I thought? Conscious of the need not to disturb what could turn out to be an important archaeological dig site any further, we stopped the dig and left the chamber.

A contact I had in the museum in Plymouth was quite excited and sent the bone away to the British Museum for radio carbon dating.

Radio carbon dating results

About six weeks later, I got a call to go see my contact in the museum—he wouldn't say more over the phone, so I had to curb my excitement.

I hot-footed it there to receive the news, "well, it's recent". Wow! Recent in archaeological terms is maybe 10 or 20,000 years ago, the same sort of age for the bones already found in Joint Mitnor; my thoughts were racing, I could barely contain myself... "human" was what I heard next... fantastic, Iron Age baking utensils had been found at the entrance to the cave (hence its name, Bakers Pit)... "around the nineteen-twenties" came next.

Firstly, disappointment flooded over me... then the realisation hit home! We'd come up underneath the graveyard. Uh-oh! Unintentional desecration, ulp!

Last respects

So out of respect, we made a last visit to the chamber, made peace with the souls we'd inadvertently disturbed and, as we backed out of the very tight crawl that lead to it, we pulled and wedged rocks behind us to form a seal. Time and the slow movement of the settling mud would do the rest. Sleep in peace.

Epilogue

A few years later I was in the Breton Arms pub, where the Plymouth Caving Group used to meet (still do?) and I got talking with them. The subject of the church and Bakers Pit came up and it was then that I found out that the vicar had noticed, first subsidence and then a hole opening up in the cemetery. As he was filling it in from the top, we were apparently digging it out from underneath. Oops!

There you go Dusty Lens, beyond the four people directly involved, the full story for the first time for all to read.

comments on photos / desecration(!) welcomed as usual

Cemetery Corner

2009-06-17T01:42:00.002+01:00

This is the next shot from my visit to Buckfastleigh to make it out of the digital darkroom. I'm still at the church at the top of the hill.

Gravestones like silent sentinels

I've always had a fascination for this particular cemetery. When I used to go caving as a teenager in Bakers Pit, a cave a lot closer by this cemetery than you'd think, I learnt about the local folklore.

The tomb of the local landowner that inspired Sir Arthur Conan Doyle to write his Hound Of The Baskervilles is in this cemetery and, as locals would have it, the Devils Toe resides on the other side of the hedge, cut off in some epic battle for the souls of the village folk hereabouts.

In the cave, one of the main entrance chambers lies almost directly under the tomb and in the ceiling of the large chamber is a coffin shaped section of limestone. Great for adding a bit of drama for any newbie to a caving expedition!

I must also confess to having been responsible for a large depression opening up in the graveyard. With a mate, we spent around 18 months on a dig in Bakers Pit, pushing some collapsed passages and a chamber at the end of them. As we dug it out from underneath, as I found out a few years later, the vicar had been filling it in from the top. Oops!

There's more to the story about bones and the British Museum but I think we'll close the book at this point!

Comments / critique / feedback welcome as always :)

Gravestones and Ruined Chapel

2009-06-15T22:43:00.003+01:00

I visited Buckfastleigh yesterday, a long over-due visit with my camera. I like the place and its surroundings, having spent many weekends camping there as a youth, pursuing my then hobby of caving.
On this visit I hung around the top of the hill above the village, where the now ruined church stands.

Old Chapel

The lighting was a bit harsh, even in the evening when this was taken. This sort of shot really deserves a blue sky, with some cloud cover to give uneven lighting and ideally some shafts of light.

But it was a cloudless day and this was the best of the four or five I shot of the chapel.

Feedback / comments / critique all welcomed as usual

Boat in Totnes Mill Leat

2009-06-13T02:42:00.005+01:00

These two shots are fresh out of the digital darkroom but I can't decide right now which one I should run with.

Portrait merits

With the portrait version, attention is sharply on the boat. The ladder is falling into shot, giving access from the ...well, we cant quite see from where, although a visual clue is there. The light catching the weeds on the right gives what I think is a nice touch of additional interest.

Landscape merits

Much more context appears in this version and there's the additional macro contrast between neatly tended potted plants and the sludge of the leat. The other thing I like about this is the cascade of "weeds" along the top right of the leat wall and the way the sunlight was catching them. There's some lovely tones there as a result.

Over to you...

So which one would you choose?

All comments / suggestions welcome

Fathers Day prize draw

2009-06-05T10:05:00.004+01:00

I'm feeling generous.... I'm having a Fathers Day prize draw where three—yes, three!—lucky names out of the Hat Of Wonder And Hope will win one of my signed, mounted prints.

(Fathers Day here in the UK is on the 3rd Sunday in June, this year on the 21st.)

Here's how you can win

To be in with a chance of winning:

you must be a follower of my blog (or have joined my site)
I have to have accepted a friend request from you, or vice versa
You can send me one by:
- finding my head in the members gadget list
- it's in the rhs column, almost at the top - look for all the heads
- click mine within the members list itself and chose 'add as friend'

You can improve your chance of winning!

Go to my galleries (mono, colour, flora) and rate / review any of my work
For each one that you do, one more copy of your name will go into the Hat Of Wonder And Hope
...and when you do, it'll help us both—your head will be next to what you write.
You do want people to be able to find your blog on my site, yes?

What makes a good rating / review

It's ok to have a review that says 'great!' or 'fab!' but it's so much more helpful in connecting with others if you say how what you're reviewing makes you feel, or what you like (or dislike!) about it. Even suggestions for improvement —'Nice! I really like this one but the horizon's a bit squint to my eye'. You get the picture :)

Maybe it reminds you of something nice or not so nice, or maybe you feel a strong connection to it for some reason. If that's the case say so. I admire and welcome honest opinions that help me see what you get from my work, what appeals, what doesn't.

You probably know yourself that feedback is the very air that artists breath, and I'm no different, hehe!

You could also click the 'recommend it' button of the works you like, even if you don't review them. That'll help those most recommended bubble up to the top. So if you do that as well, double thanks :)

The Draw...

I'll make the draw on Fathers Day and let the three winners know right away so they can let their dad's know that they have an extra special gift on the way!

Good luck to all!

May prize draw posted...

2009-06-04T15:13:00.007+01:00

RAW, HDR and related resources

2009-05-30T10:45:00.008+01:00

Since my post about RAW there's been a lot of interest and a number of questions have been thrown up. So this post gives links to and discusses resources that answer them and that I've found useful.

Expose so you bias the histogram to the right

...but without blowing the highlights.

In the full article from The Luminous Landscape, you'll read that most of the available levels of brightness that come out of a sensor's cell get allocated to the right hand side of the histogram, only a few to the left and a middling amount to the middle.

It's essential that you get this point because when you do you'll realise that the right hand side of the histogram is where you get most sensitivity to differences in shades and the left hand side the least.

Note that for HDR this means that you'll need more exposures for the shadows than the highlights to get the same number of shades (tones) in each.

The Luminous Landscape have also got a useful link to an article on understanding histograms.

Work in 16 bits for as long as possible

The topic of bit depth is covered in a quite digestible way here.

I only convert to 8 bits at the end of my workflow, when moving to jpeg:

I save my final file while it's still 16 bits so I can go back to it later, when needed
Then I convert to 8bit, do some final touch-ups such as noise removal and sharpening suited for the uses I'll put the jpeg to,
Then it's a save as, using jpeg as the file type.

Downloads and other links

Rawshooter Essentials

I still use Rawshooter for working with RAW, whether for preparing multiple exposures for my HDR workflow or the single 16bit TIFF ready for the Photoshop part of my workflow. It supports my Canon 350D's RAW files. If you do use it, it's vital

Before you download it, consider some things first. The company and software was bought by Adobe in 2006 and incorporated in Adobe Lightroom and Photoshop (see a tutorial on using their Camera RAW plug-in). Rawshooter doesn't support a lot of cameras released since the buyout, including Canon’s 5D, 40D, 450D/Digital Rebel XSi, and 400D/Digital Rebel XTi; and Nikon’s D40, D40x, D60, D80, D3, and D300. Download it here.

Noise Ninja

I use Picturecode's Noise Ninja to correct the noise I get in HDR work when I wasn't able / didn't(!) follow the advice in the article above... There's a free version but it only works on 8bit images, so useful only as a final step when converting to jpeg. Download here

DynamicPhoto HDR

I haven't tried Photomatix, though many swear by it. My own preference is DPHDR. Download here. The page gives a great explanation of where HDR is useful and what it does.

Video tutorial

I've put together a tutorial showing the processing from RAW to finished HDR image. It's twenty minutes long but don't let that put you off -- lots of people have said how they found it easy to follow and understand :) See it here.

The image used is one from my Urban Decay, Lost Spaces and Industrial Ugliness photo essay.

RAW explained in more detail

For those who want a more detailed explanation of how RAW works (rather than what it does for you, as I covered) read this.

That's all for this post. As usual comments, additional info, opposing views(!) are all welcome :)

A global conversation on B&W Photography

2009-05-29T02:48:00.009+01:00

I'm really excited by this new "web element" that Google has introduced and have added it to my blog already

Wot is a Global Conversation?

It's explained very well in the Learn More link within the gadget - a quick summary is that anyone who uses the same conversation topic for the gadget / element on their blog or site, will automatically join in to the global conversation already taking place on that topic.

And the cool thing is that, if you blog about it like I have here, people who use Google and other readers can join in right within the reader itself... Excellent :)

Here's the conversation that I've just started, the first in the world on the topic BW Photography ! All you "black and whiter"s, do join in - and embed the gadget in your site to meme the conversation :) Let's get the ball rolling! [NB The gadget you get to embed isn't specific to my site, there's no hidden links or other reference to it]

Comments welcome as always... will you put it on your site? Same topic as mine?

Some photo basics

2009-05-28T20:36:00.004+01:00

I'm sure this doesn't apply to you! But on lots of blogs I follow I see photos that could be so much better if they followed the simplest of rules when shooting them.

Squint uprights and horizons

Make sure horizons are straight -- this is really, really important with shots over water. If you forget this, you end up with what I like to call "downhill water". It doesn't occur in nature, which is what makes it jump out at you. (It's a shame 'cuz water skiing would be so much easier on downhill water!)

The same sort of thing applies to uprights. If they're not -- and they should be, then it just jumps out at you as wrong.

So remember, when you're taking a shot, just before you press the button, check the horizon and uprights. It only takes a second and your shots will start to look better right away. So you will remember, won't you! NB That's me planting an instruction in your subconscious to help you along :)

Telegraph pole hats

By this I mean anything which intrudes onto or across your subject. Sure, we've all seen shots where a pole seems to be growing out of someone's head but there's also the ones where a stray branch or boat aerial sticks up, sort of cutting the shot in two.

Easy enough to sort out with a step or two this way or that.

Shoot from eye-level

Theirs, not yours!

I mentioned this in a recent posting and it fits in nicely here, too. Whenever we're connecting with someone we don't feel natural about it unless we're at their eye-level.

Think about it... If you see someone stopping for more than lust a quick hello when they spot a friend at a table, what's the chances they'll hunker down as they speak? If someone's talking baby-talk (to a baby!), they'll get down to their eye level.

And so photos should be taken from the eye level of your subject. Kiddies playing on the floor, get down on one knee, babies crawling? Then get down on your tummy. You get the added bonus that, as you come into their field of view, they start connecting with you and you'll find your photos will take on that added atmosphere.

The same of course goes for pets, too, whether action or portrait.

Subject in the centre

Just don't! Unless it's a group photo, you know, friends, wedding....

Your subject is always doing something, within their immediate surrounds, even if it's only daydreaming and looking off into the middle distance. To convey that feeling place your subject off to one side (away from where they're looking, if that applies) or up, or down but not centre, please!

Imagine a game of oxo, or maybe a dolls house with 9 equal-sized rooms. Wherever the lines are, wherever the interior walls are, place your subject, the horizon, that nice tree, their eyes, whatever.

For even more impact in your shot place it on one of the points where two lines (walls) cross. PS This is known as the "rule of thirds".

Finally, short and sweet...

Rules are there to be broken. The only reason for having them is so that you think about it before you break them. Get used to them and then happy breaking!

As always, comments, additions, thoughts, denials -- all welcome :)

RAW setting / file type explained

2009-05-27T18:02:00.008+01:00

One of my followers, Gail (thanks for the question Gail) asked about RAW and I said I would answer it in my next post. So here goes -- note that I keep mentioning jpeg but the same pretty much applies to tiff (an option on some cameras), too.

In short

A RAW file records the output of all the tiny cells on your camera's sensor when the shot was captured, with each cell producing a brightness value for the amount of red, blue and green light falling on it.

In a sense, it's much the same for film cameras. When you take a shot, what's on the film? Just the chemical gel, with some of the light-sensitive chemicals changed by their reaction to the red, blue and green light falling on them. You then take the film to be processed to produce a negative -- a one way process.

Without RAW, your camera immediately converts the sensor output to jpeg, before storing it on your memory card -- a one way process. And because the sensor captures far more information than can be stored in jpeg format, a lot is discarded during the conversion.

What is the extra information that is lost?

The range from dark to bright recorded by the sensor is much wider than can be held in a jpeg; in a RAW file, it's like you have 7 different exposures in one, from -3 stops to +3 stops. Say you took the shot at 100 ASA, f8, 1/100s, then most digital cameras' sensors will capture the equivalent of f22, f16, f11, f8, f5.6, f4, f2.8 all in one RAW file.

Of course, with a jpeg, it records things at just one exposure setting, the one you (or the camera) set when you took the shot.

What other practical things does a RAW file allow you to do?

White Balance

This is real useful. You see, another thing that conversion fixes in stone is the "white balance". Unless you remembered to set it correctly, shots taken indoors or under street lamps can end up with a horrid yellow or blue colour cast. But with RAW you get to play with the white balance (also called colour temperature), try it this way, try it that, to see what works best for the shot.

Sharpening

Even when perfectly focused, all sensors produce a slightly unsharp image and your camera, in converting to jpeg, applies a standard amount of sharpening. Well, you guessed, a RAW file doesn't have any sharpening applied, it's something you get a chance to play with once it reaches your pc.

Downside to shooting in RAW

The size of a RAW file is much bigger than jpeg and therefore fills up your memory card much quicker, and also takes longer to save to it. It also means it takes longer for you to end up with a finished image, as you have to make all the decisions (after playing around!) rather than the camera making them for you at the time of the shot.

To sum up

RAW is like an exposed but unprocessed film.
Shooting in RAW leaves all the important decisions to you and, maybe most importantly, gives you a lot of flexibility to correct exposure and white balance where the camera (or you!) gets it wrong.

As usual, your comments and questions are welcome :)

Introspective ...Hay303 Stacks

Hay303 Stacks

A shot of the fields alongside the A303 near Stonehenge,
just after hay making. Wiltshire, 2008.

Composing and making the capture

I had seen the landscape dotted with these obelisk-like haystacks over a regular journey I make. On this particular occasion the light was right, so I kept on diving off the road down farm tracks and entrances to fields, whenever it looked like there was half a chance of a shot.

I'd not long passed Stonehenge, heading west, when I got lucky with this and another shot. [Hint: note how you "make" your own luck by giving the good lady chance to smile on your efforts!]

Placing the horizon low for airiness

The rolling hills and low clouds with the clear sky above made the scene light and airy, and I knew to capture that feeling, I'd need to put the horizon low in the frame. The rule of thirds suggests that the horizon line should go about one third of the way up in a shot like this, but I wanted more emphasis, so placed it even lower.

Three's the charm

The eye tends automatically to "zone in" to odd-numbered groups, giving them power in a shot. The scene in front of me wouldn't play ball and insisted on four haystacks, but again I was lucky in that three went nicely on the skyline with one below it.

Exposure, ISO etc.

I always keep my Canon EFS 17-85mm IS USM mounted on the camera and again it was perfect for the shot. The day was beautifully bright, so I checked the ISO was set to 100. For maximum depth of field, I set to f9, giving a shutter speed of 1/320s. As I was shooting across the road with the view often blocked by the frequent lorries that were passing, the fast shutter speed would only help. I focus- / exposure-locked around a third of the way in to ensure front-to-back sharpness before recomposing and dropping the shot into the box.

In the digital darkroom

HDR

I never have the camera set to anything other than RAW, a pre-requisite for the sort of HDR treatment I intended for this shot. I went overboard and, using RAWShooter Essentials 2006 (now a part of PhotoShop LightRoom), made 12 separate exposures from the one shot. I did this, anxious to get as much texture in the clouds and razed crops as possible. I brought them together using Dynamic-Photo HDR before moving to PhotoShop.

PhotoShop

Again, fairly standard for my workflow, I applied a bit of TLR capture sharpening first, converted to mono using the black and white filter and judicial use of the channel mixer sliders. While adjusting the sliders, I kept an eye on the interplay between sky and ground but couldn't quite achieve a conversion that convinced me. I ended up treating the sky as a separate conversion on another layer.

A tweak on the curves to increase the contrast and a slight adjustment to the levels to deepen the shadows and lift the highlights a bit and that was it.

Any comments or questions, fire away :)
