The app is a cool idea but it needs some work, both the UX/UI and the algorithm. Previews: -If I preview the photo from grid view why does it need to reprocess the image from scratch on export? Export: -No ZIP compression for TIFF??? -PackBits compression though? I had to Google that. -Why do I need to click advanced to get to my preset exports? -Why are some of the drop downs indented on the TIFF options? -No one is going to use the export to Facebook, Twitter and probably not even the Flickr one. Put my presets there instead. -What are the weird unused scroll bars on the advanced export? Overall: -The photos always seem kind of grainy. I know some of it is due to me using a high iso but it should compensate for that better. -Why can I not boost the photo more? -When you start using the app it should present you a few options to pick from to understand your taste. E.g. here are three photos, pick the one you like the most and will make yours look more like that. -The Photoshop doesn't seem to work right Lightroom -When I send to Photolumer just populate them in the grid view then I can export them all at once
