what are photography gels
Photography gels are precisely colored acetate sheets (overhead transparencies) used to alter the color of lights.There are different reasons for doing this, including for aesthetic effects and contrast reasons.hanks again-I had flash on floor behind me with red gel, flash on keyboard bounced off white paper on screen, and third flash with a home made snoot pointing to Apple logo-I made three A4 pages and got 27 gels for $4.50 Cdn.
