Most VFX Supervisors and artists now about HDRs. But they might not know how to capture and compile one. Lucky for us the tools have gotten much better in both areas!
Getting a good set of usable HDRs takes a bit of practice, familiarity with some basic photography rules, the right gear, and good communication with the First A.D. on set. Typically in pre-pro they're like yeah just let me know and we'll get you in there. But the reality is the second the "VFX Guy" drops his tripod on set to start taking HDRs the First A.D. is already yelling to "CLEAR SET!".
That's when practice and having the right tools on set pays off. And taking a fast and usable HDR data set will make your life a lot easier when you get back to the office.
I'm going to assume that we all know what HDRs are and how we use them in post production. But if you need a bit of a primer check out these links.
- Gear - what kind of gear do you need to take HDRs.
- Setup - how to setup and and be "Johnny on the spot" on Set.
- HDR image capture - the process of actually taking the pictures.
- Stitching the HDRs together.
- Processing the HDRs and getting them into your software of choice.
Feel free to hit me up with any questions along the way and I'll do my best to answer them!
