Got as far as transferring images from a GRIII into the app, which in itself is counterintuitive and tricky. Then none of the sliders seems to change the image in any way once in the app. Also doesn’t allow for import of RAW images from desktop or anywhere other than from your iPhoto app. This app should show your photo nice and large and then let you fine tune all the variables with responsive sliders. I’m honestly at a loss at how anyone can create a custom look with this
