So if you've seen the new iPhone's camera, you know it has a "true tone" flash. One is the regular blue and one is yellow for warmer light conditions. Kinda cool. Pros have been balancing the color of their flash for years with gels. You too can do this to your camera phone with these simple instructions.
1. Buy some gels. Back in my day grocery stores used to sell colored cellophane. I didn't see any so I guess this is a "back in my day" story. So instead you can order some from Roscoe. In fact they often have a multi color sampler pack for cheap. The samples are more than enough for your camera.
2. Cut the gel into the right size. Basically you'll just cut out a square big enough to cover the flash on your camera.
3. Tape it over the flash. Pretty easy, right? But what if you want to switch colors? You can try the Velcro trick. Instead of taping it directly to the phone, tape it to a strip of Velcro. Cut it down to the right size and put another strip of Velcro on the phone. There you go. Customized true tone flash for any camera phone with a flash.
