I have the potential to have my photography on a few local billboards. This would be a first for me and would appreciate everyones input. Primarily: 1. I want to be sure that I am capturing the images in the correct format so that they can be not only usable but stunning for billboards. I plan on taking these photos (of diamond rings. I know the difficulty in capturing them!) with my Canon MarkD with a product photo tent using my strobes to light the scene. I will be shooting in RAW. I would like to capture as much of the facets of the diamonds as possible and plan on using a lower powered light in front of the rings as well. 2. When I process and save the images, is there anything special I need to know to save them for billboards? I have done product shoots in the past but nothing for billboards and I want to make sure I get this right! Thanks so much for your input!
