Honestly, I think the gamma normalization step don't really count as "processing", any more than the gzip decompression step doesn't count as "processing" for the purposes of "this is what an unprocessed html file looks like" demo. At the end of the day, it's the same information, but encoded differently. Similar arguments can be made for de-bayer filter step. If you ignore these two steps, the "processing" that happ…

I fully agree regarding gamma, but completely disagree when it comes to debayering. Unless you turn 2x2 Bayer blocks into a single RGB pixel (losing some data in the process), the point of debayering is to interpolate missing data - it's upscaling of a kind after all - and you can use a multitude of various approaches to do that resulting in differing outputs.

I wouldn't worry about it too much, looking at ads is always a shitty experience. Correctly grayscaled or not.

True, though in the case of the Kindle they're not really intrusive (only appearing when it's off) and the price to remove them is pretty reasonable ($10 to remove them forever IIRC). As far as ads go that's not bad IMO)

The price of an ad-free original kindle experience was $409. The $10 is on top of the price the user paid for the device.

Don't you think you're being a bit too pedantic? Nothing really "sees". Eyes also do gather light and the brain analyzes the signals. We've invented a word for it but the word is a high level abstraction that could easily be applied to a camera sensor as well.

You missed the point. I could say more, but not to some random person who chooses to insult me.

Saying you're being too pedantic is an insult? Wasn't intended to be.

>Ultimately you can pick any coefficients you want, and only your eyes can judge how nice they are. I went to a photoshop conference. There was a session on converting color to black and white. Basically at the end the presenter said you try a bunch of ways and pick the one that looks best. (people there were really looking for the “one true way”) I shot a lot of black and white film in college for our paper. One of…

This is actually a real bother to me with digital — I can never get a digital photo to follow the same B&W sensitivity curve as I had with film so I can never digitally reproduce what I “saw” when I took the photo.

Film still exists, and the hardware is cheap now!

I am shooting a lot of 120-format Ilford HP5+ these days. It's a different pace, a different way of thinking about the craft.

Random ad hominem criticisms from strangers are insulting. Stick to substance and stop insulting people and then pretending you didn't.

Over and out.

But does applying the same transfer function to each pixel (of a given colour anyway) count as "processing"? What bothers me as an old-school photographer is this. When you really pushed it with film (e.g. overprocess 400ISO B&W film to 1600 ISO and even then maybe underexpose at the enlargement step) you got nasty grain. But that was uniform "noise" all over the picture. Nowadays, noise reduction is impressive, but…

I hear you. Two years ago I went to my dad's and I spent the afternoon "scanning" old pictures of my grandparents (his parents), dead almost two decades ago. I took pictures of the physical photos, situating the phone as horizontal as possible (parallel to the picture), so it was as similar as a scan (to avoid perspective, reflection, etc). It was my fault that I didn't check the pictures while I was doing it. Imagin…

What phone it was? I am sure that there is a lot of ML involved to figure out how to denoise photos in the dark, etc., but I never noticed anything that I'd want to describe as "AI filter" on my photos.

Even old school chemical films were the same thing, just different domain. There is no such thing as “unprocessed” data, at least that we can perceive.

Exactly - film photographers heavily process(ed) their images from the film processing through to the print. Ansel Adams wrote a few books on the topic and they’re great reads. And different films and photo papers can have totally different looks, defined by the chemistry of the manufacturer and however _they_ want things to look.

A school photography company I worked for used a custom Kodak stock. They were unsatisfied with how Kodak's standard portrait film handled darker skin tones.

They were super careful to maintain the look across the transition from film to digital capture. Families display multiple years of school photos next to each other and they wanted a consistent look.
