The role of camera profile LUTs
- Many camera manufactures provide profiles that you can load on the camera. These may come pre-installed so you simulate different color spaces right on the camera during production. These are typically loaded from a SD card or from the C-fast card. It can be stored right on the camera so you can easily apply them on set. This will allow you to shoot log, and then preview on the monitor the type of color that you're expecting. But when you get to post production these logs can also be used quickly for review cuts or to speed things up. Just don't become too dependent on them because they're not going to be perfect since lighting conditions will vary. - In this case, what I want to do is apply an input LUT. If I go up here to input I can easily browse for this. I'll take it under the basic correction. We'll explore how to access this and other tools, a little later in the course. Now there are some preview LUTs built in. And you'll see that this Alexa for log to Rec709, is a pretty good job. And here's a slightly different version, a little more conservative.... or different space. And you see how it just processes it slightly differently, versus the phantom cameras which, very different recording space. But if I chose browse, I can go and look for the official LUT. In this case, I've downloaded the Blackmagic 4k to go from Blackmagic film to Rec709. And with one click it applies the Rec709 conversion, and you see it's pretty good. The shot itself has a little bit of room left for highlights and shadows. So I still could go ahead and benefit from pulling down those blacks just a little bit, and popping the whites. Here we go, and put a little expansion there in the contrast to pull out that dynamic range. That looks better. I see my black point needs to come up just a little and now we're pretty solid. But the color is way too strong. So I'm going to tone that down with vibrance just a bit, and now we got a pretty solid shot. If we take a look at the before and after, you see that by using the LUT here from the manufacturer I was able to speed things up right away and get it so it was close, not perfect but close. And you need to remember that, the manufacturers' LUTs provided are really just preview LUTs to be used on camera. So don't freak out if you can't find one, you can absolutely build these correction from scratch but sometimes having these LUTs is a huge time saver. So consider building up a library for any cameras that you regularly shoot with.
