Oh my gosh you're right.. I completely forgot to disable macro... That's nearly as silly as trying to shoot with a lens cap on. Thank you so much, I just feel really silly now haha
Okay, so the plain white wall has no black corners, though I shot it RAW, but it does have like a reverse/inverted vignette where it gets brighter in the corners. I am able to edit the black corners out in post processing but it's a bit of a pain in the neck
I always shoot RAW, so you might be right there. I'll take a sample shot of plain white wall and see if it has the same result and report back in a minute
All of the photos in this set are all shot at the wide end (24mm equiv.), and they all look fine in camera but when I import them into my editing software (Affinity Photo), they all have the same issue
I have recently been shooting with the Canon G7X Mark II, as it's more portable and less "in your face" than my 5DIII. I've noticed that in all of my images, the corners are a solid black colour, and it isn't vignetting. I've been shooting for years and I know what a vignette looks like :')...
