I'm photographing a friend's paintings and having a really hard time with exposure. I have an EOS M50 Mark II. I've tried all sorts of experiments, none have worked. For the purpose of this post I'll consider just one. I have a painting sitting in indirect sunlight near a window. I'm using P, evaluative metering, filters off, auto lighting off (disabled), picture style standard 4,2,4,0,0,0, white balance AWB-W 0,0. The shot was f/5.0, 1/60, iso 320. Brightness +/- 0. The picture comes out dark and I need photoshop to bring it to life. Here's the rub. I take a picture with my iPhone and it comes out perfect. Any help greatly appreciated. (I've had trouble with exposure in other contexts as well and wind up setting brightness high, but for this shot increasing brightness takes away the subtle colors of the rose) Here's the two shots: iPhone photo

Is it possible something has gone wrong in my camera? That the light meter has gotten tired or blocked? Because this camera is supposed to be good for VLogging and the like and I've used it for that and it's worked great with studio lights. And my outdoor photography is coming in underexposed as well. Here's two photos again, comparing the Canon with my i Phone in not-that-bright early morning and this problem has only started happening recently.Canon

The problem is the white snow fooling the camera’s metering system. If the camera sees white it will underexpose. The camera’s metering system sees gray and it will try to make everything that way. Your phone uses Color Matrix Metering. It takes color into account when metering. Your camera cannot do that. Your phone is using what’s called Computational Photography. No standalone camera has that. So to fix the underexpose use Exposure Compensation. I don’t believe anything is wrong with your camera. Most cameras will underexpose in that type of scene.

Thanks everyone for all the help! Here's what worked -- 1) too hard to get my fancy lights to light up uniformly, so I wait for nice indirect sunlight near a window; 2) place a WhiBal card next to the painting; 3) shoot using the Exposure Compensation to get what I want and stop whining about it, and leaving it a little bit dark; 4) going into Photoshop and using Levels and the WhiBal card to set the colors. Here's one of my friend's paintings:
