1200D shooting different sized pictures at identical settings?

Go to solution Solved by Mateyyy,

Did you shoot one photo through the viewfinder, and the other using live view?

Go into your camera's settings and make sure the aspect ratio is set to 3:2 (I'm guessing it's set to 16:9 right now).

Today I was shooting some shots of the partial solar eclipse, and for some reason my camera decided to take 2 different sized photos seemingly randomly? I took a picture every minute, yet some are 5184 x 2916 and others are 5184 x 3456 in size. I didn't change settings between shots, just camera position due to the Sun moving around, and it was set to manual mode. My camera is a Canon 1200D. It's a bit annoying, because alignment software now complains about the pictures having "different lenses" and hence refuses to treat them as the same picture.

 

What could it be? Is this some image processing it does internally?

 

[Edit] Oh wait, perhaps it's because I adjusted the manual focus a couple of times? Very strange that it only has these two versions though as that was by no means a consistent process.

Well, I know on some cameras there's an option to save 2 images: a RAW and a JPEG. Are they in the same file format? 

Is it plugged in? Is it turned on? Are you sure? No, really.

I save both RAW and JPEG, but they show the same difference.

I did indeed switch between having live view on and having it off to save a little battery and the aspect ratio was indeed set to 16:9. Is that really it? never would have thought that... I readily admit I'm a not-even-amateur photographer, but that is one I would never find on my own.

 

Is there a way to fix this in post to make software think they are the same? For example cropping the bigger one or something.

That obviously depends on the software you're using, though I reckon cropping the larger image to the exact size of the smaller one should do the trick.

Yeah of course.  Cropping them indeed did the trick for my purposes.
