But my experiences with HEIC are, apparently different than his..... A lot of that is two people with different criteria. but in this case, my rather arcane use may be the reason in which we differ... My wife and I do a few activities to keep us active... one of which is to monitor the condition of Monk Seals in Kauai.... basically we get a call and go out to look at, set up barriers around, and overall assess the health condition of these endangered critters. Sometimes we are asked to baby sit one. Part of that assessment is to identify which seal we are dealing with.... We take pictures of the critter and send them to NOAA (to the local Vet and protector of the Monk Seals).? To do this I have purchased an old but quite good 500mm F8 lens ( mirror) lens. Mounted to my Nikon D7100, it really blows up the details so that I can read the tag on each animal.... The tags are about 2x4 inches, bright red, with white ID numbers on them... There are 2 tags, one on each rear flipper.? I can usually get the number from about 35 to 45 feet away.? Take pix, blow up in camera, read tag, take more pix to see whole animal. FYI, and nerdy indeed, I take RAW images,? Inspect in LRCC, convert to Jpg for transmission to the vet.? I keep the RAW images for my photo gallery. But sometimes I do not have my camera with me.... in which case we use our iPhones to do the ID and assessments.? This is where the HEIC compression was insufficient.? The images that I transferred from the phone to the computer were WAY too compressed.? Blocky, and useless.? Remember, I am trying to read the 2x4" tag from 35 feet away with a lens of 32mm and a pixel pitch of roughly 1micron.? It requires blowing up as big as possible.? HEIC just does not cut it. Now maybe my use is a bit weird or specialized ( it is) but it showed me that blown up to 1:1? on a 15 inch laptop using LRCC, made the images useless.? Something needed to be done to fix the ability to read these tags.? JPGs work,? Heic does not. Having said all of this, it is a tangent on the overall complaint... APPLE changed something in the way my phone works without my knowledge nor agreement..... Just like they always do..... Leave my settings alone! If you want more details on what a Monk Seal is and why it is important to maintain health awareness of a wild critter.... ask me and you will get your answers... WARNING.. it is VERY VERY nerdy.
