Question: Do the filters have the color name printed on them?
Document: So. I use color filters for a white bladed custom lightsabers. This certain brand of filters are okay because of the more unique colors. They are a pain to cut though because the filters are so thin. But other than that I really like the filters.
I bought this filter book as I needed some color filters for a light responsive micro-controller programming project. The project is done with but I keep finding more and more uses for these filters from coloring the flash of my little point and shoot camera to observing the world through different filters and filter stacking for a combined effect.
These work great if you purchase a light saber or make one for yourself with a white LED. I used these on an Aeon from Ultrasabers to change the color with my &#34;Adegan Silver&#34; color.I have also used them to get cool color effects shooting by attaching the swatchbook filters to my Canon Speedlite and bouncing light and what not.Very smooth texture and easy to remove from book and cut.
Awesome selection of filters. I use these with my camera to get nifty filter effects.
I was so excited to receive this in the mail! I had misplaced my gel filters to my Lomography Diana Mini and this wheel of amazing filters gave me so many more options than the 12 that I lost! Thanks again!
The Roscolux filter sampler is an excellent tool for a pinhole (or other, small lens photographer) who wants exacting control over filter selection. The Roscolux filters include a transmission curve for each filter. An excellent buy.
This is a good product and wonderful for quick photography filters, but the company I purchased this from on Amazon sent a swatch book that must have been used because the were several filters that were pulled out of the book and missing. All that was left was the cards that corresponded to the missing filters with the filter numbers on them.This was very disappointing!
I needed small pieces of colored gel filter material for my flash lens. This product has a large selection of filter colors which can be reordered individually, the filters fit the flash lens without trimming, and the price is great. A very useful product.
Has gobs of their most useful filters. great to use to determine your filter needs. Shipping reasonable from vendor, do not believe other posts with complaints regarding shipping charges. They must have mistakenly ordered air rush options. No complaints from me. Just choose the best shipping option for you.
This swatch book has every color &#34;Gel&#34; needed to alter the light from a flash, so the photographer can create a different mood.
Answer: They are not printed directly on them.  There is a card behind each filter that has the info on it.
