One of the quickest and most used tools in lightroom is the radial filter. A quick adjustment in brightness to a face or something else that needs lifting from a photo. It is awesome and quick. Trying to achieve the same thing in AP-ipad took me 10 minutes with layers and masks. Would have been 20 seconds in my old desktop version of lightroom. I don't subscribe to Adobe and never want to, but I do want to edit photos when away from my house. (hence AP-ipad)
Affinity said they were making a DAM app I am wondering if that is something similar to LR? If they already have many of the features of LR inside of photo it doesn't seems like such an app would be all that hard to do.
