Picture of DIY 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. Professional sets can cost a fortune, these cost me $14.25 (not including the transparencies, which I already had), and are great for any amateur photographer!

Step 1: Making Them

I went online and found the standard color values for a set of gels. Using these, I made an 8x10in jpg file for each color. Attached is a zipped file containing all 27 images that you can burn onto a CD.

Once this is done, take the CD and a pack of acetate sheets to Kinkos, or a similar printing venue. Kinkos only charged me $0.49 a print.

Easy as that.

Could you use these to project images for stage lighting? I am looking into using these for stage lighting at my church and was wondering I could use them like GOBOS
Lighting gel used in theatre and film will run 5-6 US dollars depending on the supply house. The color media is 20in x 24in and more heat resistant than overhead transparencies.

Out of curiousity, is the $.49 just for the printing in color, or does that include the pricing of the acetate sheets? I ask because when I went to Kinkos and asked about how much it cost to print transparencies (which I'm assuming is the acetate sheets) in color, the guy told me it was $1.99 per sheet.

I brought my own transparencies, so it's just the printing.
BTW, has anyone tried out the Fellowes Crystals clear plastic binding covers for their DIY Gels? I ask because everywhere I've gone to that has acetate sheets (transparencies for projectors) have ranged up into the $35+ range for the cost for 50 of them, and I found one store that has the Fellows Crystals Binding covers (basically the professional grade plastic covers that requires the machine to bind a stack of papers by using a plastic spine) for only $13.99 for a pack of 25. I'm asking because I don't know if they are good enough to withstand the printing process. The only cheap transparencies (other than the Fellows product) are for the ones you write on (and I don't know if those can stand the printing process at Kinkos.

I would worry that something not designed for printing might melt inside a laser printer. Kinkos wouldn't be happy.

Thanks for the input, but I decided to go with inkjet transparencies I picked up at a Goodwill for $5 (comes with 50 sheets).
Thank you. I was wondering about that, so at least now I know the difference. :D

Why are some of the colors appear different? Example the Blue N+1 appear like Magenta and the Green N+3 appear to be turquoise? Also where are the yellows?

Just want to ditto photoman22. The colored report covers are cheap. Stacke 'em up for intensity. Thanks for zip file, I'll give 'em a go. BTW, I tried the request for the free swatch book from Roscoe but they were overwhelmed once it was mentioned on the Strobist blog. B&H has the best price
COOL, I needed them for night vision stuff

Sweet! Great idea! Have they melted at all under the heat of the modeling lights?
Weissensteinburg (author)  chrisrioux6 years ago
I mostly use them on my speedlights, so they haven't spent too much time in front of a modeling light. The transparencies are used commonly on overhead projectors, though, so I'm sure they'd hold up pretty well.

Instead of buying gels, I went to Office Depot and bought a package of colored acetate report covers. I cut the covers in half and have two sets of "gels" that work great.
Weissensteinburg (author)  photoman0226 years ago
That's a great idea!

You can buy a gel sample pack from Roscolux for about $2. Here is the B&H link:

If you contact a production company (in the Northeast, APLS or ECLPS) they will send you one for free.

That looks great!
Thanks 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.
Could you explain the printing of the these a bit more? What did you tell him to print?
Weissensteinburg (author)  kencaruthers6 years ago
I simply brought the files in and told them that I wanted each one printed on a transparency.

I wasnt able to download your gel file, but I did figure out that I can do it directly in photoshop for any colors that I want (VERY large variety) and then have them printed... thank you for the information!!!!
Weissensteinburg (author)  Rue7 years ago
Your welcome! I'm glad you're making good use of it.
This is pretty neat. Though, I do have a question concerning the type of transparencies used. Do you use the copier transparencies or the inkjet transparencies?
Weissensteinburg (author)  Kier7 years ago
I honestly have no idea. The pack that I used happened to be free for me from school, and it was a very generic pack...wrapped in shrink wrap with a stick that had a bar code and said "Transparencies" or something like that. Sorry.

Cool. Downloaded your color file and have the transparencies printed at Staples for $.48 each. Taken a few shots and they work great. See a couple of the pictures attached. Thx.
