I also wanted to show you how to take images like the product shot I did for the clownfish kit which is taken as is in linden water without retouching. I think un-retouched photos are important in product shots for honesty. So here's how I did mine.
I created a gradated background of the ocean floor in perspective. This is an alpha that I then textured a prim with. You can see that the general tone of the photo from this distance is hued. This is because this shot is set in Linden water.
|In closeup , this background is particularly effective for introducing distance|
