Quick few questions:
What is the best method for editing and saving a final version out of Photoshop? At the moment I am saving for web as a JPEG at %100 quality and it seems to do an okay job.
Would it be against the rules to retouch the image to remove some artifacts as a result of rendering reflections? I can see distinct quads where the algorithm hasn't quite meshed with the surrounding grid.
Also the addition of a surface layer, which I was sure to mask to a very certain are of the ground, has messed up the shadows on the mountain. I am using displacement intersection on the new layer, and disabling it removed the errors. Can I render in two separate passes and combine in PS? My last render was 75h long due to the high samples I used for the water, which actually turned out a lot worse than I hoped.
Overall it looks good, you will see it soon I hope
