Normal people use jpeg. It's good enough, much like mpeg-2 was good enough for DVDs. Compatibility always beats storage efficiency.

Photography nerds will religiously store raw images that they then never touch. They're like compliance records.

I think most photography nerds who want to save edited images to a lossless format will use TIFF, which is very different from the proprietary "raw" files that come out straight out of the camera.

You'd be wrong in my experience.

No photog nerd wants EVEN MORE POSTPROCESSING.

I don't understand. You've got to save the edited result in a file somehow. What format do you use?

The file as it comes out of the camera, so-called raw, is a family of formats. Usually such files are kept untouched and any edits are saved in a lightweight settings file (in the format of your editing app) alongside the original.

And a low of RAW format are adopting or considering adopting JPEG Lossless as codec.

Is that like how javascript was named so as to imply a connection with java, in spite of there being none?

JPEG is the ur-example of lossy compression. JPEG Lossless can't have any connection with that.

I'm not even really a hobbyist photographer anymore, but when I was, the full lossless edit was a .psd and that was generally exported to (high quality) jpg for distribution. I have folders full of carefully curated raws. For the relatively few that were ever edited they have an accompanying psd. The jpgs are ephemeral and don't get saved long term.

Most raw files are TIFF with proprietary tags.

Normal people just use whatever the default on their phone is. Which for iPhone is HEIC, not sure about Android, AVIF?

JPEG, or fancier jpeg: https://developer.android.com/media/platform/hdr-image-forma...
