I've been playing around a lot with the Photo Mode in Mass Effect Legendary, and while I love that they added it (it was nearly impossible to take screen shots in the Mass Effect game before they came to Steam), the controls are a bit limited, at least to me, even with the Photo Mode Qol Mod for ME1. I also wish there were just a single key stroke to activate it (which would make it much easier to take a combat screen shot), but as it is, you have to hit ESC to the main menu, then click on photo mode, that's kind-of a pain.
Still, it's better than not having a photo mode, and it is fun to play around with the focal length, angles, filters, and saturation and other options., I've probably spent several hours overall just experimenting.
I love playing around with the B&W mode and Film Grain
The sepia tone can also be pretty nice
And, lecherous old man that I am, I've spent way too much time photographing the exotic dancers at Chora's Den:
