IPad Questioni
Dec 26, 2017 13:53:59 #
In going through the features of my iPad Pro and iPhone 8Plus, I noticed that under camera, in the settings menus, I have a choice of either “High Efficiency” or “Most Compatible.” I’m not sure what this means, and I don’t know if this has been asked about here before. Can anyone enlighten me as to what the preferred setting is? Thanks.

Educated guess: in the new version of iOS it has a new kind of compressed image format which it says is higher efficiency. However, it will automatically, it claims, revert to JPG if it is not certain that the destination can handle the new format. An example of a destination that probably can handle the new format would be the latest version of MacOS.
If it works as advertised you have nothing to lose by selecting the high efficiency but I'd recommend a little experimentation.

As A6K has alluded, Apple has started using the HEIC format for images in their latest devices, instead of JPG. 'High Efficiency' gives you the new format, 'Most Compatible' gives you JPG.

I just ran into this problem with my Windows PC. One of the latest updates to my iPad caused it to use the HEIC format, which worked well with my iPhone and iPad sharing, but was totally unable to load the HEIC formatted photo into Elements 2018. I found an online file converter site for my Windows computer, and tried it out. Rather than the nice crisp image my iPhone had captured, I had a very low quality, almost claymation picture of my friend's daughter.
No thanks, I'm sticking with the "Most Compatible" JPG format.

I read somewhere that an upcoming update for Win10 will provide native support for the new format.

Ok, I think I got the idea. I have everything Apple, so there should be no conflicts. I think my confusion was with the "most compatible" selection. Now that I know it's JPEG, all is well. Thank you all for your responses.

The HEIC format is 10 bit per channel I believe rather than the 8 bit per channel of jpeg while not as good as a true raw file if you are looking to post process there may be some advantage. Perhaps going from HEIC to 16 bit tiff to jpeg for the final output. Unless there are some editors that can work with the HEIC format directly.
Just a quick look suggests Lightroom CC and the latest Photoshop supports HEIC but Lightroom classic doesn't.
interesting article

It wouldnt be too bad if it can be translated into a more supported 16bit format

Just FYI, there are a few apps for iOS that improve on the OS-included camera and which also allow you to save in TIF/TIFF. The iPhone/iPad dynamic range is not as good as most DSLR and mirrorless cameras but it can be made better in some cases by working with the raw image to begin with. Yes, I'm equating TIF with raw in this case. My two apps of that sort appear to be saving in an uncompressed TIF which is, of course, what I want.
This is more or less the opposite of a high efficiency form of compression but you have a choice that you can easily make when you decide what camera app to use.

This is likely a desktop app. Just guessing.
