I have had a look at your website and its photography section - i downloaded a photo to analyse the metadata on there and there is no camera setting data present which would show up on Renderosity.  Are you using the same method of saving for the photos on your website as you are for Renderosity?

Also what version of photoshop are you using?

In every stone sleeps a crystal.
Remember the Shaman, when he used to say:
Man is the dream of the Dolphin"
