Everyone knows jpeg compression is undesirable, which is why some apps give us the option to save images as uncompressed tiffs. On the computer you would always work in tiff format to avoid compounding jpeg losses, like making a photocopy of a photocopy. If this is new to you, it is important.
I'm concerned about the app-to-app chain within the iPhone, iPad, or iPod. Few apps support and save tiffs. So we take all the care to save the original image as a tiff, then open it in another app, edit and save, this time jpeg is the only option. Jpeg compression losses. Now we move on to another app, more editing and resave as jpeg. More losses. Now we add a frame in another app, and save to jpeg. More losses. Now we go and add a photo credit line in another app. More jpeg compression losses. This is getting serious. It's a good thing that grunge effects are so popular.
It looks to me like the most desirable thing is to shoot an image, save it as a tiff and continue to do all the editing in one app before the final save, preferably to tiff.
Does anybody else worry about this?
I have noticed that some apps can pass an image along for further processing to certain other apps within the phone. In this case, is the image being saved and reopened or is it actually continuing work on an open image without jpeg compression losses in between?
