I know dogs and cats have different eyesight than humans, with different color perception. I could not find anything showing this…I was wondering if anyone has seen an image edited to reflect what it would look like from a dogs perspective?
I can’t find an image, but this link clarifies how dogs and cats see:

ETA: Here’s a link to the dichromatic aspect:

Thanks!
Hey, anything to avoid what I’m supposed to be doing.
Geessh. When I read that I reluctantly went back to seeing appointments. 
I like the explanation of what cats see in the dark at the bottom of the last one 
Yeah, but the picture of The Queen Mother is most intriguing. What’s with the black bar over the crotch of the guy sitting next to her? The goofy smile on his face leads me to some good guesses.
That’s not her mother, that’s Queen Elizabeth herself. This URL (borderline NSFW) Does Photo Show Queen Elizabeth II and a Colonel's 'Crown Jewels'? | Snopes.com has the unexpurgated version of the picture, as well as another version that casts doubt on whether there was originally anything there worth blacking out.
*** Ponder
Something to keep in mind is that, if dogs and humans are like rabbits, the eyes perform preprocessing and send multiple streams of images, each stream designed to detect different things (movement, shadows, etc.)
My point is that dogs may have different sets of images that the eyes forward to the brain than humans do. It might be more complex than just color detection.

I think this is much more important than color perception. Humans see fairly differently from most other animals, even many other primates. We have unusually good eyesight for figuring out complex shapes. For example, as I understand various readings, it would be hard for a dog or a cat to figure out what shape peg fits into what shape hole no matter how smart they are, because their vision isn’t much help making sense of the shapes. Humans can do things like weave and tie knots and insert integrated circuit packages into printed circuit boards, even if we’ve never done it before, partly because our sight is optimized for it. Don’t envy hawks for being able to see a mouse a mile away - I don’t think a hawk could ever learn to read the SDMB, no matter how big his brain got.
If I can I’ll find some cites for this, but I think I’ve read this in a variety of places over the years.
