@dillonk I used 5 different colored gels. Gels are like what you on the stage lights in plays and theaters, it's just a colored piece of plastic meant to go in front of the light. I also used to strobes.
I'm loving this piece best of all so far, I think. this collection is great! might I recommend you move the table of contents around so that your artist statement always shows up first? I went back to reread it and thought doing so might help those looking to learn more about your collection.
