Summary: For color balancing SB-800s, for coloring backgrounds, or for special effects or accents, these gel filters work excellently with the SB-800. There are 20 filters, with 2 of each color and 4 of red and blue. The fact that there are multiples and they are pre-cut to fit exactly makes them a better deal than buying a Roscoe sample pack and cutting them to fit. All in all, it is a pretty cost-effective, simple way to extend the usefulness of the SB-800.
Summary: I know, everybody says "Why pay so much when you can just get a big sheet and cut them to the right size?" Well, I decided to go ahead and get these, and I've been really pleased with that decision for two reasons: 1. They are pre-cut with a tab that slides down between the wide-angle diffuser and the lens. This makes using these gels a snap! No need to cut out little pieces or tape them on. Bing-bang, you're done. No hassle! 2. It's like a "variety pack".
Pros: Clear Optics, Consistent Effect, Firm Mount, Strong Construction
Summary: The main purpose of these gel filters is to help a SB600 or SB800 compensate for different lighting situations. They are also excellent for adding a creative flair to a backdrop during remote flash shooting. My favorite use is for placing a pool of colored light onto a light gray seamless backdrop during portrait photography. It really enhances the subject.
