Aperture replacement - I need to compare photos side by side
I used Aperture as my database for all my clinical photography and it was great with smart albums as well as comparing before and after photos. I don't need fancy editing as my photos must be true, so the most I would do is cropping.
Photos can do all the above EXCEPT comparing two photos side by side in the same screen.
Does anybody know of any software that will allow me to do this? As well as keyword and smart album my photos?
