Canon EOS Rebel T7 not saving manual settings?
Hey there,
I have a Canon EOS Rebel T7 as my Photo Booth camera. When I am adjusting the manual settings for appropriate lighting, shutter speed etc it is only keeping the settings for one picture. It then reverts back to all different settings.
The first pic in my post is how I'm setting it, the second is what it reverts to.
I've tried literally everything I can think of; I've reset the entire camera's settings twice, cleared and reset any custom settings, took the battery out for awhile, and shut the camera off for 24 hours.
One thing I did notice is that the camera only stays powered on when connected to my Photo Booth. I'm kinda camera dumb if you will, but surely if it's charged through the computer, it should still turn on even if disconnected? I mention this because the only thing I can think of is that I need to replace the battery?
Overall just very confused and frustrated. Any help is appreciated.
