HELLO

With an enormous amount of pride and an equal measure of surprise I am the featured photographer with my photograph ‘A Hard Day’s Night’ on the website PHOTOBOTOS.com - why not take a look.

The image had earlier been shown in 500px.

500px described itself on its Website as a photo community powered by creative people worldwide that lets you discover, share, buy and sell inspiring photographs. I have recently become a member of 500px and I thought that I would share a photograph that I have submitted with you and as shown above. I am pleased to say that it has had quite a few viewings and comments. What do you think of the photograph … good or bad,  I would still like to know.

Until the next time.

I have just started to use redbubble for the sale of my photographs – take a look inside.

Hello

Some more images for your perusal using a different viewing experience – I hope you enjoy this presentation of High Dynamic Range (HDR) images.

DID YOU KNOW

The two main sources of HDR imagery are computer renderings and merging of multiple photographs, the latter of which in turn are individually referred to as low-dynamic-range (LDR) or standard-dynamic-range (SDR) photographs.

Tone-mapping techniques, which reduce overall contrast to facilitate display of HDR images on devices with lower dynamic range, can be applied to produce images with preserved or exaggerated local contrast for artistic effect.

High-dynamic-range photographs are generally achieved by capturing multiple standard photographs, often using exposure bracketing, and then merging them into an HDR image. Digital photographs are often encoded in a camera’s raw image format, because 8 bit JPEG encoding doesn’t offer enough values to allow fine transitions (and also introduces undesirable effects due to the lossy compression).

Any camera that allows manual over- or under-exposure of a photo can be used to create HDR images.

Some cameras have an auto exposure bracketing (AEB) feature with a far greater dynamic range than others, from the 3 EV of the Canon EOS 40D, to the 18 EV of the Canon EOS-1D Mark II. As the popularity of this imaging technique grows, several camera manufactures are now offering built in HDR features. For example, the Pentax K-7 DSLR has an HDR mode which captures an HDR image and then outputs (only) a tone-mapped JPEG file. The Canon PowerShot G12 and Canon PowerShot S95 offer similar features in a smaller format.

Until next time
