I setup a photo studio in my office. I have a green screen, Cameron’s recording lights and the Cannon 50d on a tripod tethered to my computer. It’s a complex setup. I’m using FOSS called entangle (to capture) and the Gimp with Darkroom plug-in to open the Canon RAW image files. I’m learning about f-stop and ISO speed. It’s all complex and I’m out of my depth a bit but it’s fun. It’s been a while since I’ve messed around with Adobe Photoshop. I’m trying to relearn a skill on Gimp and it’s a bit different. I’ll get the hang of it sooner or later.
