That's fair enough, thanks for taking a look into it anyway!

Thanks for taking a look! I haven't used Expo, but looking at the docs I wonder if using 'allowEditing: false' and 'exif: true' in the ImagePickerOptions would bypass reencoding? The gainmap is stored in the EXIF data. Instagram is similar in that the gainmap is stripped if you edit the image at all, cropping included, but if no crops or filters are done then the image retains the gainmap.

Either way if the clients are able to render the HDR images, I think uploading on web is still a usable implementation.

Do you have any plans to support Ultra HDR images, on the Android app and/or other platforms? I did some browsing of the site and didn't see any examples (but that doesn't mean it's unsupported).

I really enjoy that aspect for sharing photography on Instagram, and the support (at the client level, at least) is fairly straightforward (see https://developer.android.com/media/grow/ultra-hdr/display).

The idea of the platform does sound great, and the application seems very polished from what I can tell so far.
