This is a simple guide on creating DIY Flash Gel kit, you’ll need a laser transparency sheet and access to a color laser printer. I’m not sure how accurate they are, but they do change the color of the shot. I figure I’ll try this instead of spending $25 on ebay.

Hear are the PDF templates
CTO -CTB Window Green
CTO -CTB – Window Green 1/2 CTO – 1/2 CTB – 1/4 Red
Colorfull
This how the document looks, It contains CTO, CTB and Window Green on a single sheet. I want to thank Richard from www.urban-exploring.com for the Gel Scans I used to get the color.

I used a old pack of Transparency Film that I had laying around.

Here’s the sheet after printing it!
These are the strips once separated, I placed a strip of packing tape in the center on each strip on the printed side to prevent it from rubbing off. I then cut them to size and added some Velcro dots.
