Hello! I've recently been thinking about photo editing in iOS and, more specifically, the use of high resolution files via Photos. I've noticed there's two options when it comes to the new iCloud Photo Library, either you can have your device download a full resolution copy of all of the images in there, or you can have everything stored solely in iCloud and only ever view lower resolution so-called 'optimised' versions of your images. But here's where my confusion starts. If you have this optimised storage feature enabled, how then would you access your full resolution files? If you were to 'export' or share a photo (or open it within another app, via Photos) from within Photos, under this setting, would said exported/shared photo be high resolution or would it be this optimised version they speak of? If I want to work with high resolution images, is the 'download originals' setting gonna be the only option for me? In which case, would the purchase of a 128GB iPad Air 2 be a necessary investment if I were planning to use it as my primary photo editing device (Sony A6000, SD reader, VSCO Cam)? I'm happy to purchase as much iCloud space as necessary to cover my needs (not really for long term photo storage) but if it's physical storage I'm gonna need, I'd rather know that now. Ps. Slightly off topic but related, I have iCloud Photo Library set on both my iPhone and iPad with the optimised feature enabled, yet my iPad is reporting 1.7GB of photos stored physically on my device. Surely this should not be the case if I've told the device to use iCloud as its photo storage?
