Jul 12, 2016 12:44 AM in response to Zooted11by Terence Devlin,I would warn you that Tiff is an uncompressed format and therefore the file sizes are huge. I wonder would high quality jpegs suffice. How will you be using these images? If it's only for showing then there's no point in having images that are higher quality than the screen you're showing them on.

Jul 12, 2016 8:15 AM in response to Terence Devlinby LarryHN,Correct
BUT
The OP requested the "least amount of compression" and zero is less than a little hence instructions on doing an uncompressed image
with the least amount of compression?

Jul 12, 2016 9:02 AM in response to Zooted11by Old Toad,You'll need to know that if you export the files as TIFF files the file size will be increased by a factor of 10-15, i.e. a 1.5 MB file exports at 24 MB. I doubt if your iOS devices will be able to hold those files.
Unless you plan to printing extremely large prints from those files you should not be concerned with additional JPEG compression. These articles discuss jpeg compressors and image quality:
Does Saving a JPEG Multiple Times Reduce Image Quality
If you export the photos as originals there will be no compression and you can then upload them to the iOS devices as already described.
