Hi, There are lots of threads about the new Photos App Beta, but I thought it would be good to have a central thread for general discussion about the App and a place to share experiences good and bad. Obviously this is not a replacement for providing Feedback through the Feedback Assistant. I haven't had a really good chance to try out the App yet, but my first impressions is that it is a positive improvement from iPhoto but obviously not a replacement for Aperture. It feels much lighter and faster. I am disappointed that Aperture is being discontinued but I am evaluating this app simply as an iPhoto replacement rather than Aperture replacement. Hopefully a Photos Pro will be released one day and Apple will bring some focus back to enthusiast and professional users. I find the white background quite bright and distracting on the eye, however the dark/black background in fullscreen image view is nice. I would like to see dark background across the whole app. The previous version of iPhoto used grey/black background across the whole app and was a not so harsh on the eyes. I also hope they will provide a slideshow option without music. Currently every slideshow theme including classic theme has music and no option to turn it off. Hopefully other will share thoughts and experiences. Cheers!
