Is there anything I can do to try to match a shoot with a T3i and HMC150? I know they will never look like the same camera no matter what you do but is there anything to help match colors, ect?
I usually start by setting the white balance to be the same in both cameras before shooting. You should also shoot as flat as possible. When you start to grade, the tricky part is exposure. Unless you are in a very bright environment, you'll probably want to bring the Canon way down and bring the 150 as far up as the footage will allow. There are no shortcuts I've discovered, you just have to dig in and play until it's perfect or the deadline stops you. Here's one of my shoots with a T2i and a 150:
I found the easiest tool was Colorista II. You need to go in to the hue wheels (not the 3 way colour) and yank some specific colours around (not just the white balance) to make them match. The way the two cameras render colour is completely different.
