[Leica] Warning to iPhone users..... Thanks Apple......

[Nathan Wajsman]

Thanks for this, Brian. I am not commenting on the photography bit, but rather the second half of your message. I will share the specification document with my daughter who, in desperation due to the Covid pandemic, started studying her second degree in 2020, in computer science. I am sure she will enjoy this.

Cheers,
Nathan

When I am shooting something where resolution matters, I click the "RAW" button that option enables (on the top right of the app screen). You all know what RAW format is and does.

It sounds to me like your app might accidentally have used the preview image and not the main image. I use Adobe Camera Raw to poke around inside HEIC files to see what's there.

If the system misbehaved, IBM would solve the problem and fix it free of charge. Every couple of years the contract would come up for renewal, and the scaredy-cat owners always paid the money to renew the software warranty.
>    What it meant to "behave" or "misbehave" was that there was a 100-page document specifying what IBSYS 13 was supposed to do, and if you could demonstrate to IBM that it was not doing that, they were contractually obligated to fix it. I may well have been the only employee there who had read and understood the entire Specification document.

This was before the era of FedEx, so it was hand-carried by a courier all the way from Armonk NY. My boss gave it to me to read. It consisted of one sentence: "The full specification of IBSYS version 13 is defined by its behavior."
