I just had a tour of the Zeissimages gallery, and it includes some attractive sorting options-- by member, by orientation, by whether the image is film, by lens (all Zeiss), etc.
One concern: The EXIF option appears more basic/less robust for user input than RFF. I for one would miss being able to enter filmtype/iso, for instance, with its enabling corollary (being able to search images by filmtype). I'd love to have those user-options carried over, even if they're more hidden to ease navigation and to improve real estate for the image.
And a second concern: the Zeissimages implementation of comments and likes seems cluttered/redundant in one way: if you sort by "all comments," you also see all the likes too, with the message, "A 'Like' on a photo counts as a comment even if no written comment was entered" --which quickly gets tiresome to reread, and which tends to bury the real comments. The RFF gallery has a good culture of commentary; it would be a pity to bury the comments and critique with auto-generated text about likes.
Mainly though: Thanks for taking care of this, Jorge.
