It's recently occurred to me that many aspiring photographers may want direct feedback on their images in a structured way. Sure we can like and comment, but maybe there's something more.
Now when you upload a photo, or look back at your past photos, you can simply choose to allow critique. If you check the box, you'll be open to ways of improving the photograph, and users can rate the image on certain criteria.
I'm hoping this new feature provides a mechanism for real image feedback. If you don't check the box, you'll still receive likes and comments as usual.
