Adobe editing software the most used in the world for a reason.

It's sensitivity, duh, expressed in µV per electron ...

It is never late. When Nikon stopped supporting Capture NX2, I moved to the Lr. I still have all my RAW, procced in CNX files archived on my external hard drive and converted them to TIFF to use in LR. Sometimes I want to revisit my edits (from CNX) and I do it in LR from scratch. Even if I revisit my edits with LR, I start from scratch.

Are you disputing my choice of words or the concept? It feels like disputing a lawyer where your opponent is constantly arguing against something else other than the actual issue.

For me, the crucial element in raw file editing is that the edits are never fixed. You can continue to tweak them forever without damaging your raw files. Big difference to raster editing where you have to keep creating duplicate files to do edits while retaining your original out of camera file.

Let me illustrate with a real world example:

After the recent purchase of a P900 printer, I came to understand that when printing A2 sized prints, sharpening needs to be different than when printing A4 prints. I have 20,000 raw file edits with excessive and unusable sharpening for larger prints. If I had only raster images, I'd be screwed. Fortunately, they are raw files and I have a perpetual licence for LR and I can go in and back off the sharpening for larger prints.

Under the subs model, my files would all have been converted to what ever the latest LR version is, and if I later unsubscribed, I would not be able to go back and adjust the sharpening as I can now. Therefore, unless I agree to pay Adobe forever, I'm stuck with a back catalogue of raw edits I can't change. Even one tiny bit. Despite the fact I paid a perpetual licence fee for that right.

I consider the knowledge of the existence of "minor" little issues like that as "holding my edits to ransom" and the subscription a kind of protection racket. I paid Adobe for the right to edit my images perpetually in the past. That right should exist in perpetuity. I can only retain complete control over those past edits by not subscribing.

Adobe could change the rules so the import module get locked if you stop subscribing. That would ensure you are:

a) blocked from editing images created after you stop subscribing

b) Still able to continue the edits you already paid for when you bought the product and made those original edits.

There are other subs models. They could let the software continue to work perfectly you after you stop subscribing except for any features added after you stopped subscribing. There are any number of subs model function restrictions possible (similar to how shareware works) that don't remove your control over your past work. But no, they decide to apply the most draconian version of the deal possible - one in which all the advantages lie with them. Not playing ball.

Well said!

Although RawTherapee does have separately saveable (i.e. re-usable) and editable sidecar files (PP3, type 'text') I don't know if they can be taken elsewhere.

First, the "duh" is not helpful.

Second, if you're talking at the input to or the output from the source follower, and that is your definition of sensitivity (it wouldn't be mine), then it does change in most modern sensors that I've measured.

I never do output sharpening on an image until I'm ready to print, and then I don't keep the file that's undergone output sharpening.

I don't think it needs artificial restrictions on XMP portability for there to be a problem. A command stored in an XMP might do something in another program, but unless it does exactly the same thing, your edits will be scrambled. darktable can read LR XMP data, but it only gets you a half edit file, they are simply not compatible.

I can think of more Draconian ways of operating. They could prevent the program from opening, for example.

No doubt that's a good policy, but it doesn't help me 🙂 Anyway, that was just one example. No doubt there are lots of things that can be done to a file that would also be frozen under the subs model.

It's particularly frustrating that edits that were done in a perpetual licence version, become non perpetual if you pay Adobe more money to join the subs program. What kind of deal is that!

"I can think of even more Draconian ways of operating. They could prevent the program from opening, for example." Fixed.

Seems to me that this is a bit of a stockholm syndrome answer.

I stand corrected.

Perhaps reasonable in context since the discussion is about the common error/lore that the ISO setting changes the sensor sensitivity ... with the said lore being based on the older sensor>PGA>ADC path and not on Aptina-based and not on fancy ISO modes.

The 'duh' was in response to the wording of the question - either rhetoric or a trap.

I'm not getting your point.

Kind of the opposite, since I have the freedom to change the files if I want to, yet I haven't seen any reason to do so.

Am I to understand that you have made 20,000 prints already? Wow!

I messed up the quotes just before you posted and edited it after ... please look again ... sorry

My main point is italicized in the quotes above.

The concept. They are not holding your edits hostage, just preventing you from making new ones. Losing your job doesn't mean the company goes to your bank and password-protects your accounts, it just means you aren't making more money.

Actually, that's a bad example because LR has post-sharpening in the export module that can be controlled. Adjust it there.

They could, but they didn't. That doesn't mean they are holding your edits hostage, just preventing you from making new ones.

I strongly recommended this model to them before they changed, and they didn't listen.

I understand this from their point of view. After a while, software is well-developed and no one will pay for endless minor upgrades, so it's not a good growth business model. That doesn't mean I have to support it as paying for things I don't use isn't a good business model for me, and I don't.

You should look at ACDSee. You can subscribe OR purchase. Your choice.

Got it. Why not define sensitivity in terms of charge/light so it works whether the sensor uses dual conversion gain or not?

Of course not! Although I am surprised how many prints I have made since the printer has been yelling at me that the starter carts are empty. It keeps on going. Just ignore the warnings.

Nah, I made my choice 4 years ago. LR perpetual for old stuff and printing, darktable for new stuff.

I wouldn't use LR for printing if I could figure out how to do printing properly in Linux without having to pay Turboprint hundreds of pounds. I like TP, it's good but it doesn't do anything I can't already do with LR. The Apple CUPs printing method Linux uses is baffling. I can print just fine from dt/linux but it doesn't look quite right and I can't bothered to try and sort it out.
