Regarding the topic below, the process that is used to create such photos is HDR processing. HDR stands for High Dynamic Range. In a nutshell, this photo is obtained through digitally combining the same photo but with different exposure. The different exposures are either obtained from the camera, by setting it to take 3 pictures at once, 1 stop under exposed, normal exposure, 1 stop over exposed. Or it can also be modified, by tweaking the exposure of the same picture on photoshop.

It combines the pictures, thus as a result as shown by the pictures, there are very little shadows, making everything bright, it also gives the allusion of being a painting.

And yes, it is banned in competitions as it removes the realism of the photo.

Hey guys, just to add onto what Nigel said,

HDR photos are usually made with 3 or 5 exposures, but they can extend to 7 or even 11. Up til a certain point, it is safe to say that the more exposures, the more comprehensive the dynamic range and thus the "better" the photo, if thats what's intended.

HDRs do not necessarily remove the realism of the photo. While there are such cases (e.g. http://flickr.com/photos/mmojana/2477565871/in/pool-hdr), there are also photos which use HDR to enhance realism, such as http://flickr.com/photos/mmojana/2477565871/in/pool-hdr .

But yes, it is banned in competitions, I guess partly because different people have different definitions of "realistic". This is just to clear up the assumption that HDR removes the photo's realism.

cheers,
kenneth.
