When you are the talent and you are filming yourself without any help you can run into issues like setting the exposure. I could not find a way to do this with the EOS Utility software to simulate someone half way pressing the shutter button to find the right exposure.
In this video I’m using my 18% gray card to find the perfect exposure for my studio setup.
One of the biggest things I learned from the exercise is if you don’t have your exposure spot on, it can mess with your skin tone colors. For instance just being a couple F stops off can make you look like you have a sun burn.
When I went to use the gray card it occurred to me that the metering modes can change the exposure a lot so I started looking in to it more and more. What I did was to take a series of photos in aperture priority mode so all I was changing was the aperture and not the 1/50 second shutter speed or the ISO which I had at 200.
These are the metering modes on Canon T2i 550D, these can only be used when shooting pictures you can not select them when shooting video, it appears when you are in video mode it uses one of the middle two:
- Center-weighted Average Metering
- Spot Metering
- Partial Metering
- Evaluative Metering
It appears to me in my studio setting the most accurate metering I can use in video mode is the middle two: Spot Metering, Partial Metering. See the T2i 550D manual on page 86 for an illustration of what they look like.
I think I finally have the exposure and skin tone color done within camera correct now.
- Auto Lighting Optimizer: Standard
- Highlight Tone Priority: disable
- Picture Style: Standard
