Arri Look Creator for the Arri Alexa, is a really useful little piece of software that I didn’t really get into until recently. It’s still in it’s 1.0 beta, but the idea is that you capture a still .dpx image in LogC from the Alexa. You take the SD card out of the Alexa and bring the .dpx file into your Mac with the Arri Look Creator on it. You can make fairly detailed color decisions with the tools and create a “look” with the DP or director right there on set.
