I felt like I did an ok job of blending the flash and available light. I knew that it was florescent light. I started by just using a green gel on my flash but it still left the photos with a twinge of green. I then added a ½ orange gel to the green gel and that seemed to match the available light. I couldn’t figure out why there was a weird shadow on the bottom of my photos and then realized my shutter speed was too high.
