Battery? - what battery?

A ““working”” photo is something people can look at and recognize what it is. I don’t care what L5 claims is a working camera. Mayhbe, just not this one.
Settings for “Camera (Dev” or millipixels if they are not the same, and set them to what?
I gather the settings must be set before taking the pic. A trial and error scientific approach I read. And, only outdoors and on good sunny days, no snow, while whatever it is we’re taking a picture of doesn’t move. “Hold that pose you two - while I set this up to take the pic of the Groom kissing the bride.” Awww she looks so good in her YELLOW gown! It’s really white. It’s not working. No ads or sponsors can force people to believe that it is working. If it worked, we wouldn’t have the issues, a lot of other have complained about.
