ah, the fruit of my labor. custom fit for both of my flashes, the 500EX and the 420EX, two sets of gels for the two sizes. it’s amazing what kind of effect they have when used…now the trick is to figure out how to use them more effectively. i think that they are too hot in my initial testing, so i suspect that i will need to take longer exposures, but i’m not sure. i guess i have a lot more learning to do when it comes to lighting.
