The Gel Swatch Library by Crossroads Motorsport, LLC., lets lighting production personnel browse, search, and compare more than 1,600 gel color filters made by the most popular manufacturers:
- Apollo
- Lee
- Rosco

The Gel Swatch Library lets you:
- Search for gels by name or number
- Sort gels by number or how they're arranged in the physical swatchbook (forwards or backwards in the swatch book)
- Compare similar and complementary colors
- Examine each color's detailed Spectral Energy Distribution graphs by turning the iPhone or iPod touch sideways
- View CMY/RGB percentages or DMX values for any color
- See the last 21 colors visited with the "Recently Viewed Colors" list
- Send comments directly to the developers with the "Feedback" button

We have added two great new features we think you will love:
1. Live view of colors in the gel item or gel comparison view with either front or back cameras.
2. Or see the same gel views over any photo in your library.

Both of these features are available as an in app purchase. Both of the features can be previewed for free with our pre-chosen colors (G-101 & G-305).

The Gel Swatch Library is perfect for:
- Theatres
- Churches
- Cruise ships
- Corporate events
- Educational theater programs
- Nightclubs
- Theatrical dealers
- And many more areas of the lighting world!

Essential Cinematography iPhone app

Thank you for the latest Gel Swatch iPhone app update.

The ability to use my iPhones camera or a calibrated photo to preview thousands of gel colors plus compare gels side by side over the image?

This update is a game changer for my location scouts, tech meetings and those quick “What gel looks good here?” moments.

I can’t wait to use it out in the field and on-set. It’s top of the stack now in my iPhones Cinematography Apps folder.

One suggestion on improving the app.

If the apps photo preview feature gave us the ability to selectively erase or paint on an area of the color gel overlay (for still photos only, not the live camera) this would really help in coming up with complex color combos. The ability to show Production Designers, Set Painters and Props people where a gel color wash will play on a live set would be incredible for an iPhone app.

Tiffen used to have 2 iPhone apps that allowed masking to a certain degree with their camera filters overlaid on top of still photos. They sold it off I believe and it’s now called “DFT” aka Digital Film Tools in the iPhone App Store. It still functions the same and I use it all the time.

I don’t know how complex app coding is but just a thought on taking the app to the next level.

Have a great New Year!
