HEIC is a terrible file format.

Rant on: Every year I work on the end of year slide show for the kids Mtb team. Every year I have a google drive where I ask parents to upload photos so I can use them (90% of the shots I use are from my own DSLR/Mirrorless cameras). Every year, I get UNUSEABLE heic shots from iPhone users. HEIC is so tightly compressed that heavy edits the photos and exaggerate the flaws. I often get, sharpening artifacts around edges, weird banding in skies and strange colors. I HATE them.

HEIC might be a great storage format, but a lousy sharing format.

It reminds me of Sony, just inventing new formats for the purpose of being a pain in the arse. Memory stick, Mini Disk, etc.

If your pic/vid is already compressed, then switching to any other compression is bad but a single compression should t be awful.

I'm extracting them into photoshop of Vegas Pro and then outputting them. But they look awful no matter what program I open them in.

Don't most of the newer iphones capture pictures in the .dng ProRes/lossy form now (if enabled)?

I'm definitely no photographer though... dunno.

Do iPhones not support RAW?

I Never used digital 8. I always used DV tapes and DV converters and never had issues. I heard about it, but by the time I was knowledgeable in the field even DV was dying and slowly being replaced with direct to DVD or internal hard drives in the consumer market. The Professional market was still mainly BETA SP, Panasonic’s DVCPRO eroded some of SP’s dominance in the broadcast market even as Sony created its own Professional flavors of Digital and HD on Special BETA SP tapes. Eventually HDV would come out as the last tape prosumer format before switching to Memory sticks or SD cards.

Sure. They can read them, and some android phone cameras can even image in that format. But it's also not the PRIMARY image capture file format like it is for Apple phones. However, that's not the issue.

The reason Apple switched to HEIC, wasn't because of image quality, it was mainly to save onboard space. With no option for expandable storage like many Android phones, Apple needed a more efficient format to keep users from running out of memory with photos and videos. The trade off was off the apple ecosystem, the file format suffers from the problems noted above.

I recently converted ~3000 .heic images to .jpg using opensource digikam in batch mode. I haven't done anything demanding with them, but the look fine.

For a while I had lots of trouble with .heic txted from wife's iPhone to my Android. One or both phones must have had some software upgrade. They now automatically come over as .jpg.

All I know is anytime someone sends me a HEIC image, it won't open.

I know it will change just based up me posting this, but the original post got 24 UVs to 0 DVs? When I posted this, I thought BEST case it woul be 50/50.

Truly surprised that this many people on this type of forum dislike the format as much as they do.

To reiterate this point, microsoft charges $0.99 to download the HEIC codex.

Pretty much all other codex are free. Microsoft makes you pay for this one.

terrible.

I don't understand the issue. I convert HEIC to JPG all of the time without issue. The quality is fine.

Because you’re most likely just looking at them on a 6-inch phone screen or posting them to Instagram or Facebook, where the compression algorithm mashes the pixels down anyway. If your "workflow" stops at posting them to socials, then sure, HEIC is "fine." For an actual photo or video editor, they're garbage.

If you worked with the files beyond just converting them, you'd understand the issue. The second you try to push the exposure, pull up the shadows from a dark area or color-correct a shot, the entire image disintegrates.

This is because HEIC uses video-style compression (H.265), where it doesn't preserve clean pixel data. Instead iit creates a mathematical approximation of it to save storage space. As a result It groups smooth gradients, like skies, into flat blocks. This is awful when you are trying to work with files for eventual video work or printing.

I view them on my 30+ inch ultrawide monitor without issue which is fine if you're doing a slide show. I've never really gotten into the details of photo-quality editors, so I will defer to your judgement and requirements.
