Lots of ice, thats the only water that should be permitted in whisky
I think the biggest problem with this competition is they have not thought about the rules too well. They have allowed images to be processed in photoshop but they have not specified anything else with regards to styles and technique.
All three images are, in essence, a single RAW that has undergone some fairly basic processes, just in a very exaggerated and stylistic manner, no extra elements/subject matter have been introduced, nothing has been replaced or subtracted from the scene, all subjects remain in position as during the point of exposure. It's the post processing that has caused doubt.
There's been some dodging and burning in all three images IMO, is this acceptable? It is with film but is it or has it ever been during a photojournalism competition?
The first and third examples are much more colourful and have more detail in the shadows, this can be argued that it's not photo journalism.
The second pic is dreadful in my opinion, I think he left that one in the oven far too long, he would have been better off lighting the subject and using a little creative license in that way and not during the pp phases IMO, but would he have been disqualified for that also?
