So this app is about as close to a merge-to-HDR solution for exposure bracketing as I've seen anything come so far, at least as far as iOS apps are concerned.However it's a little disappointing that it won't detect RAW format images in the Photo Library and will save as JPG. You have to move them to the Files app for it to recognize a DNG and merge to a TIFF.It should allow you to choose between JPG or DNG (if available) for images in the Photo Library, as well as allow you to choose your output file format. If the dev can add those two things, easy 5 star.I'll be sure to update my review if that change is made.
Developer Response
Thank you so much for your detailed review and suggestions! We’re thrilled you’re finding the app useful for HDR bracketing. You’re absolutely right about RAW/DNG support with Photo Library and output format options—we agree those are must-have features.We’ll be working on fixing that immediately so you can import directly from the Photo Library and choose your preferred file format. Your feedback really helps us improve quickly. Hopefully we’ll earn that 5⭐ from you very soon!
Not usable with Canon camera

Probably the only solution for RAW exposure bracketing on iOS. I was expecting high, yet the result is basically not usable. Combining multiple CR3 RAW photos does not preserve bright areas at all, even with quality priority selected. Not sure if those underexposed ones were indeed processed. Moreover, the "bracketing" also creates mysterious purple hues around all items captured in my photo. On the other hand, combining multiple Canon JPGs will simply crash the app again and again. Wish I could have a refund.
