Tattoo

2010-05-03T11:19:00.000-07:00

Tattoo is an art made by inserting indelible ink into the skin to change the pigment for decorative or other reason.

The term "tattoo" or from Tahiti, "Tatau" is first referenced by Joseph Banks, the naturalist aboard Cook's ship the "Endeavour" in 1769 where he mentions it in his journal. To paraphrase. he states, "I shall now mention the way they mark themselves indelibly, each of them is so marked by their humor or disposition".

Tattoo enthusiasts may refer to tattoos as "Ink", "Tats", "Art", "Pieces", or "Work"; and to the tattooist as "Artists". The latter usage is gaining greater support, with mainstream art galleries holding exhibitions of both conventional and custom tattoo designs. Copyrighted tattoo designs that are mass-produced and sent to tattoo artists are known as flash, a notable instance of industrial design. Flash sheets are prominently displayed in many tattoo parlors for the purpose of providing both inspiration and ready-made tattoo images to customers.

Art and love this s what Wedding Photogarphy is. Once in our life we will declared and us blessing for God the we and our partner will be for better or worse till death do us part..

Wedding photography is an art expressing once in life time and most precious moment of our life.

The images was taken at Sharjah UAE.

Light Painting

2010-01-17T01:47:00.000-08:00

Digital Photography is an art with the use of light. This images was done using the Light Painting technique only pen light was th available light source and made it very creative. This concept is very interesting since no other equipment used aside from pen light. Using SLR camera and setting the Aperture and shutter speed properly to take same images like this.

Sharjah Gold Souk

2009-11-28T14:01:00.000-08:00

Sharjah Gold souk one of the Historical and Old structure in UAE an excellent architectural that to the present is still the tourist attraction of Sharjah. Night shot practice of Night Photography using Canon SLR 1000D and tripod.

Digital photography and photographers are more interested in Historical place which passion, try to shoot and post there art adding impression with the History.
Night photography required tripod since it is set in the lower aperture and slow shutter speed as much as possible try to use cable release to avoid any shake and blurry image.

insects: The bee and the dragonfly

2009-10-25T11:36:00.000-07:00

Insect and close up shot are more interesting in Digital Photography, it also a challenging shot specially when capturing a best photos.

The following shot was taken in the La Union Philippines using Canon 1000D SLR camera.

while bee playing around with the flower and working hard to do his duty its very interesting to captured the image. Best images happen every time so always ready to captured those moment.

Dragonfly taking rest and make a pose in this photo. Using 55-200mm telephoto lens and setting the camera to the right aperture and shutter speed to get this image. But this will be better if macro lens was use.

Digital Photography can develop by practice and by passion.

Portrait of Unknown Lady

2009-09-12T09:11:00.000-07:00

In digital photography one interesting subject is the portrait or the picture of the person.
This shot was taken at Dubai Heritage Village. The lady in the photo was really unknown we don't even know her name.

This lady was actually the model of some Filipino groups of digital photography class here in Dubai. I just join with them to take some shoot and eventually left after taking some portrait of this lady. What you see now is the result of my shot using my Canon SLR 1000D.

Lenses

2009-09-02T08:04:00.000-07:00

What is the basic function of lens and its characteristic?

In digital photography the lens is the most important part of a camera that takes the light that enters the camera and focus it on single point to form a sharp image/s. Its basic function is to admits a large amount of light permitting proper exposure in a small fraction of a second.

Lens Characteristics
Lens speed - refer to the amount of light that a given lens can transmit in a given time. The aperture part of the lens that controls the amount of light that reaches the film or CCD in digital camera.

Focal length- the distance from the center of the lens to the sharp image produce on the film plane or CCD when focused on infinity.

In digital photography Lens are classified as:
1. Wide angle lens- lenses with a focal length of 35 mm and below.
2.Normal lens- lens not particularly wide angle and not telescopic. For SLR camera lens of 50mm
is considered to be normal lens.
3. Telephoto Lens- lenses with a focal length longer than the normal lens (above 50mm focal length).
4. Angle of Coverage- Sometimes referred to as Lens Field of View- depends upon its focal Length - the longer the focal length the smaller the angle view.

Depth of Field

2009-08-29T00:02:00.000-07:00

Depth of Field
Let us try to fully understand Depth of Field, in digital photography it is one of the most important aspect to consider since we already understand the exposure.

What is Depth of Field?

The depth of field (DOF) is the portion of a scene that appears sharp in the image. Although a lens can precisely focus at only one distance, the decrease in sharpness is gradual on either side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions.

Depth of field (DOF) is the distance wherein objects are in focus.

This is the pragmatic explanation.

To be technically correct, DOF is the zone of acceptable sharpness, the area in front of, and behind, a focused subject that appears in focus.

Circle of Confusion (COF)

Technically, only the subject in focus -- and all other objects at the same distance -- are in focus; everything else in front and behind are out of focus. How much out of focus depends on a term called the "Circle of Confusion (COF, or COC)."

What Affects DOF

What we really want to know as photographers is what affects DOF so we can control DOF in our pictures. For a long, long time, photographers have gone with the following three criteria in digital photography:

lens aperture
distance from subject
focal length

While the first two are technically correct, the third one has raised somewhat of a storm of controversy among certain circles. Why exactly, we will make clear later. Let's look at each of the three criteria in more detail.

A short depth of field can be very useful when you want to isolate your object from the background, such as when taking portraits or macro photography. A large depth of field is great when you photograph landscapes and overall when you want every detail to be in focus.

Control the Depth of Field

There are three variables that affect DOF in digital photography, the size of the Aperture, the distance to the object and what lens you’re using. (There is a fourth thing that affects the DOF, but that’s the size of the sensor and unless you have two cameras with different sensor sizes this isn’t something to take into account.)

Exposure: ISO

2009-08-27T01:50:00.000-07:00

WHAT IS ISO?

ISO is the sensitivity to light and it is important to learn how it works in Digital Photography.

The ISO setting on your camera is something that has carried over from film. Remember back in the ‘old days’ when you used to go and buy your rolls of film and you would buy film rated at 100, 200 or 400, maybe even 800 or 1600? Well that number refers to the film’s sensitivity to light. The higher the number, the more sensitive to light the film is. The ISO bit is from the standards for film sensitivity, and the number refers to it’s rating.

So what does sensitivity mean? Well a low sensitivity means that the film has to be exposed to light for a longer period of time than a film with a high sensitivity in order to properly expose the image. With a lower sensitivity you also get a better quality image too which is why you should always try and use the lowest sensitivity you can get away with. Let’s not get ahead of ourselves though, a little more explanation is required.

You might remember buying film for a sunny holiday and the shop assistant would recommend using a film rated at 100 or 200. If, on the other hand, you were going to be taking pictures indoors, then you might be recommended a higher sensitivity like 400 or maybe 800. If you used ISO100 film and decided to take some pictures indoors, chances are you would need to use the flash, or your pictures would come out quite dark. This is because the film’s sensitivity is so low that the shutter would need to be open for a long time to let enough light in. Your camera may not have had the features to allow it to keep the shutter open for long enough, which is why you ended up with dark pictures.

This was one of the problems with film. Once you’d loaded it into your camera, you were pretty much stuck with that film sensitivity for 24 or 36 shots.

Bring on digital cameras and you can now change the ISO setting for each shot you take. That is one of the big advantages of digital photography.

So why do you only get choices like 100, 200, 400, 800, 1600 and maybe 3200 when it’s digital, surely you could set 154 or 958 if you wanted it? It’s only electrical currents and circuits after all, not a piece of film. Well, in theory you could choose any setting you wanted, but imagine how tricky that would be. There are three settings which combine to give you the exposure, these are Aperture, Shutter speed and ISO. Each one can be changed individually to allow you to set then to what you think will give you the perfect exposure, or you can let the camera set them for you to what it thinks is the perfect exposure for the conditions it can detect. Already with three different options, each having several settings themselves, the combinations are numerous, so keeping ISO to set values, which people will understand makes it a little less confusing.

Now, I mentioned quality too, and that better quality images are achieved with a lower ISO number. If, again, you go back to film days you may remember the sort of grainy effect some images had. Well this grain effect is what is introduced with a higher sensitivity film. Digital has it’s own grain effect with higher sensitivity and is known as Noise. Digital noise can be seen a sort of speckley effect in areas of similar colour, like skies or dark shadow areas. It is a subject of much discussion and the camera is often judged on the amount of noise it produces at these higher sensitivities. This is why you should always try and keep your ISO set to the lowest number, and use aperture and shutter speed to get the right exposure. If you can’t do that with aperture or shutter speed, move up to the next ISO setting and try again.

Why is a high ISO setting needed? Well for indoor work, where flash isn’t allowed and the light levels are fairly low. Or you can use it deliberately to get the grainy gritty feel to the image (although I would prefer to add this later on the computer).

It’s well worth experimenting with ISO settings so you can see just how your camera performs at the various levels. Once you have got to grips with how changing Aperture, Shutter Speed and ISO effect your image, you’ve pretty much got all the technical fundamentals nailed.

Over at the Digital Photography School Blog there is a nice post on how to choose the right ISO setting which is worth checking out.

Exposure: ShutterSpeed

2009-08-25T23:56:00.000-07:00

In Digital Photography the shutter speed is one of the most important elements to consider to have a impressive shot, but let us understand fully how the shutter speed works.

What is shutter speed ?
The aperture diaphragm of a lens (bigger or smaller values) and timing (open and close) of the camera's shutter curtain - both perform the tasks of regulating the amount of light entering the camera and expose onto the film. The shutter speed scales engraved on the shutter speed dial of conventional camera bodies with a shutter speed ring OR via some flickering digital numerals on the LCD screen like: 1/8000, 1/4000, 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8, 1/4, 1/2, 1 or -1, -2 etc. are essentially indicators of the duration (timing) at which the shutter curtain opens up and closes during an exposure process. A 1/125 setting means the shutter curtain open and close within one hundred and twenty five of a second while 1 means an one full-second the shutter opens up during exposure to absorb the available light source onto the film to form an exposure.

What does shutter speeds do ?

In principle, shutter speeds, like aperture value detailed on earlier section, contributing as the next half of the main components for any exposure process - the interval at which the shutter opens to allow a specific amount of light (also depends on the opening of the lens diaphragm) to pass through and expose the film inside..

Different selection of shutter speeds will yield different kind of visual effect on a final photograph. Generally, a fast shutter speed can freeze action while slow speed can blur your image. I am not indicating these are fixed rules. If you understand the nature of how various shutter speed(s) will affect an exposure, you may put them to creative use to enhance the effect - like other than freezing a fast action scene, a slow shutter speed can also put to good use in portraying movement. You can try on to "PAN" a moving subject by following its direction or simply generates a sense flow of movement. But MOST people relates SLOW means BLURRING AN IMAGE which leave little for them to select this alternative to try them out. Well, it is excusable because in most PR-type of photography (photo session on public relation matters like wedding, gathering, seminars, or personal domestic duties for some privileged group - includes your wife, mistress or girl friends..), who would appreciate a defocus or blurry images ? BUT - for the creative minded photographer, slower shutter speed sometimes may create a more powerful visual impact than images taken with action-freeze high shutter speed(s), say, a free flowing river, traffic, a flock of birds taking off or even speed-demons on a race track.. etc..

A basic mechanical SLR camera body like the Nikon F2S of the mid-seventies only offers manual exposure control. AE may require accessory such as DS-1 to transform it into an shutter priority AE camera.

A camera operating in manual mode or a mechanical camera requires you to set the shutter speed and aperture value on the lens manually. In an automatic camera, there is usually at least one type of automatic exposure mode is available. Because of complication of mechanism involves, most camera manufacturers offer only Aperture Priority AE or Programmed AE modes on their EARLY electronic camera models. A good example is Minolta and Canon with their MD and FD mount cameras and lenses while in some exceptional case, such automation was made possible using a mechanical device such as Nikon's F2 with their EE Aperture Control Unit.

However, by early '80 with development and refinement made on both cameras and lenses (Most would require a new series of optics), majority of them started to offer "Shutter Priority AE" and "Intelligent Programmed AE" as well.

Exposure: Aperture

2009-08-25T04:59:00.000-07:00

In Digital Photography the exposure is the most important aspect to consider by the photographer. Exposure mainly composed of three basic thing Aperture,Shutter speed, and ISO, but let us focus first in the Aperture.

Let us first understand the what is the effect of aperture in Digital Photography.

What Is... Aperture?

When you look at the technical specifications of a digital camera, one of the very first specification mentioned is its maximum aperture and/or its aperture range.

What is 'aperture,' what is a good aperture range, and how is aperture relevant when it comes to choosing a digital camera?

What Is Aperture?

Aperture is expressed as F-stop, e.g. F2.8 or f/2.8. The smaller the F-stop number (or f/value), the larger the lens opening (aperture).

[Note: Many camera user manuals today will refer to the aperture in terms of "aperture value" instead of f/value. I'm not sure when this trend started but don't get confused between "aperture" and "aperture value." Aperture value" is simply another way of saying f/value.]

In practice, unless you are dealing with a fixed-aperture lens (many simple point-and-shoot cameras have only one fixed aperture), the aperture of a lens is usually expressed as a range of fstops.

When you read the specifications of a camera, the aperture may be expressed in a number of different ways, the following three being the most common:

Maximum Aperture:

Max. Aperture

F2.8

This simply states that the maximum aperture for the lens is F2.8.

Aperture Range:

Aperture Range

F2.8-F8.0

This states the max. and min. aperture, the assumption being that there are standard increments between them.

Maximum Wide-Angle and Telephoto Apertures:

Aperture

F2.8-3.5 or F2.8(W)-F3.5(T)

This gives the max. aperture for the wide-angle (F2.8) and telephoto (F3.5) focal lengths of a zoom lens.

It is usually not too difficult to figure out that a stated range deals with maximum apertures and not max and min apertures: the mimimum aperture should be quite small at F8, F11, F16 or F22.

A "fast" lens is one that has a large maximum aperture (F2.4, F2.0 for current digital cameras; F1.4, F1.2 for 35mm film cameras.

Type of Camera

2009-08-04T10:00:00.000-07:00

Types of Camera

The camera or camera obscura is the image forming device and photographic film or a electronic image sensor is the sensing medium. The respective recording medium can be the film itself, or a digital electronic or magnetic memory.

Photographers control the cameras and lens to exposure the light recording material (such as film) to the required amount of light to form a "latent image" (on film) or "raw file" (in digital cameras) which after appropriate processing, is converted to a usable image. Modern digital cameras replace film with an electronic image sensor based on light sensitive electronics such as "Charge couple devices" (CCD) or " complementary metal-oxide semiconductor" (CMOS) technology. The resulting digital image is store electronically, but can reproduce on paper or film.
