> Turns out “delete after import” was a huge mistake. That's a mistake no mater what application you're importing to, else we'll be graced with another blog post, "Darktable app Corrupts Photos". What's the purpose of RAW+jpg though? Seems rather redundant?

Thanks dad.

> What's the purpose of RAW+jpg though? Seems rather redundant? You get to keep out of camera jpg files. Some people might like how their camera processes jpg files and might also want the raw file for a scenario when a more complex editing is needed.

Interesting, based on this and other replies, it sounds like Photos App should have an option to select what to import? i.e. RAW or jpg, but not both. It sounds like Photos App can have issues trying to import both at the same time?

As I said in my blog post, it imports both and combines them in the UI. Also as I said in my blog post, I switched to shooting only in raw, and it still exhibited file corruption.

He says the checksums are different but he doesn’t provide a diff to show how different. It could just be a single flipped bit or something. And that could happen in his own RAM/disk/CPU/router so seems premature to immediately blame Apple.

Here you go! https://gist.github.com/tenderlove/25853f50ab46a58738ff2cc22d682f2b I ran both files through xxd then diffed them. I've literally changed every piece of hardware (at no small cost). "premature to immediately blame Apple" seems a bit off.

This is the kind of stuff that makes me wish my Binary Diff Tool was already completed, but unfortunately I'm still working on it. Can't tell much what's wrong with the differences in the bytes without knowing what the structure behind it is.

I tried running the file segments through a binary diff with Hex Fiend

As far as I can tell:

- 0x7800 bytes were replaced at file offset 0x00aa0000

- 0x2200 bytes were replaced at file offset 0x00aa8000

I can't tell if the replacement data came from a different part of the file, or somewhere totally different. Race condition somewhere sounds plausible.

This is also my guess. It's really a bummer, and I'd report it to Apple but since it's nondeterministic I have no idea how to provide repro steps.

I have had extremely bad luck, reporting bugs to Apple. They constantly ask for an example project, even if it's something that is easily demonstrated, simply by running existing Apple software, and creating a project, would be a huge pain. They also ignore reports. Very rarely, I may get a ping on one of my reports, asking me to verify that it was fixed in some release. Otherwise, there's no sign that they ever even…

> I guess you can't argue with the results, as they have a market value North of 3 trillion dollars

This was financed by equally massive technical debt.

What's brilliant about it? What's the reference, for those of us unfamiliar?

It is simply hilarious to make grown adults visit a website called tender love making dot com (a sexual reference) to read a very specific and niche blog about technology.

I feel like this is a URL that I don't want in my history

There is a very popular professional audio website called Gearspace that had a much spicier name for a long, long time.

Apple corrupted images on my iPhone where I can’t import them to my PC via photos, but I can backup the whole phone. They finally recognized there is an issue, but there is no fix, as of a few weeks ago :(

Yeah, that's one of the billion reasons I'm sticking to Android phones with gasp file managers and shock expandable storage via an SD card slot.

I never need to import anything when I can simply copy the data from the card.

From your description, your experience is quite typical.
