When I was a kid, my dad used to poke fun at me for mismatching colors when I dressed myself. Ha, ha, the joke was on him: it turned out I'm red-green colorblind. As an adult, I wasn't even able to print my own color photos until the digital world made my deficiency nearly irrelevant. (See my article "Even a colorblind person can color-correct a photo.")
At $34, EyePilot might be a viable solution to some of the hassles faced by colorblind people.
One tool I've used for some time is WhatColor, which helps me to identify tricky (for me) colors in photos and to copy the hex codes for use in other applications (mainly Photoshop).
I had unprecedented help from the Internet yesterday.
I was booked for a photo shoot in Brooklyn, N.Y., which is about 75 minutes from my home in southern Connecticut. The shoot was scheduled for 7 a.m., about 45 minutes after sunrise — so I knew the sun would be out. But when shooting in New York City, tall buildings can block the sun. Not being familiar with the neighborhood we were shooting in, I didn't know if the sunlight would be accessible, even in broad daylight.
Enter the World Wide Web. I typed the address into Google Maps, switched to "Satellite" view and scoped out the area. I saw that our location was bordered on the south by a stadium-less track and baseball field. In winter the sun rises in the southeast, so I could tell the morning light would fall directly on my shoot.
Remote reconnaissance. Cool.
(If you're curious about what I was looking at, here's the satellite photo. We were shooting on the tennis courts.)
