I have started doing a small series of lighting and material studies on my own by trying to recreate photos. The main purpose of this is to try and learn and see what it is that makes it look more realistic and doing it in a small scale so i later on can add this (hopefully) new found knowledge to use when creating larger projects.
The first image is a photo of a pooltable, i like it cause it had, dof, the photo was imperfect in several ways and the lighting looked not to complex at first glance (turned out it was a bit harder than i thought to get it right).
I didnt care to much about the placement of the balls and thier “colors/numbers” in relation to the photo. The main goal was to get the materials, textures and lighting correct.
Here is the result, I spent approximately 6 hours on this. Render time was around 50 minutes, on a pretty slow laptop. Hopefully you cant tell wich is photo and which is 3D 

I have also started a second one, its in a really early stage, just modeled base shapes i havent even chamfered anything yet. I have also tried to get the framing right and lighting. Will start adding details to the modeling (not that it will be much though), and fine tuning the lighting and then create the textures and materials.
Early wip of the current one, quite obvious at this state which is 3d and which is photo.

Any thoughts, suggestions or feedback on this would be greatly appriciated
