The best raw image processing tool I know is called “RawTherapee”. It was developed by one or more absolute colour science geeks, it is CLI-scriptable, its companion RawPedia is a treasure trove of information (I learned many basics there, including how to create DCP profiles for calibration, dark frames, flat fields, etc.), and not to make a dig (fine, to make a bit of a dig) you can see the expertise starting with…

IME in photo post-processing, good UX, smooth multi-photo workflow and intuitive controls beat technical details every time. RawTherapee is better than Darktable. But that’s a pretty low bar to clear. There are reasons people pay for Lightroom.

I used RawTherapee a ton, but changed to Lightroom because the denoising is so much better. (I’m sure a more expensive camera would also help here, but I have what I have.) Now that I’m used to Lightroom it will be hard to switch back.

Yes good point. But my needs are very limited. On macOS I use the Photo app to cull, make small adjustments, and crop. On Windows there is also a Photo app that allows such basic features. They both works with RAW and works fine with my NAS mount in smb to cull directly the files (though macOS is a pain for that, doesn't play well with files, need to import in lib). On linux, the default Gnome image viewer is nice bu…

I windows I highly recommend IrfanView just for basic photo viewing (odd name). It's extremely fast.

Yes I've used it and it's very good. Too bad it's not on Linux and macOS.

A big difference is bit depth. BMP normally is 8bits per pixel per channel (colour). RAW is often more bits (say 10 or 12 or even more). This means you can adjust lighting without introducing banding and so on.

HDR output is present in ART, which is a fork of RawTherapee. But it is not really usable, as the preview will show the beyond-SDR areas as pure white or something like that. I.e., you will be working blind.

Maybe take a look at GraphicConverter for the Mac. While it isn't a file Management tool, it's really useful for tweaking various details.

RawTherapee is great in most ways, except that all of the curves for adjusting anything have absolutely catastrophically bad handling. It's so amazing having access to the Lab colour adjustments but the sliders are abysmal, impossible to make any kind of precise adjustments, impossible to reset an individual slider/point back to it's default placement, impossible to undo the last action without resetting the entire widget to its default state. It's unusable, and I'm convinced that the popularity of it would skyrocket if they'd finally just sit down and address that it's miserable to use. I would drop lightroom in a heartbeat if they made them even a little bit better.

I know it's a different space, but as a counterexample, FabFilter makes audio plugins that are the gold standard for that kind of interface and it isn't even close. Anybody making an interface for interacting with points on a curve should sit down with the free demo of FabFilters Pro-Q3 for just a few minutes to experience what's actually possible and how it should feel.

Partner is getting into photography and I don't have the stomach to purchase some software. I threw darktable and rawtherapee on the table but without technical grit you get nowhere really fast. It's no my wheelhouse so they are mostly in there own.

I've been getting into photography lately too and running into the same question. There's no way I'm getting an adobe subscription. But I'm not sure what tools do I want to pick up instead. Apple Photos has gotten me pretty far, but I'm hitting the limits of what it can do. And my photo library is getting pretty big now - big enough that I want some software to manage where my photos live as well.

Capture one?

Firstly it's a matter of reliably storing image files. I just make a new folder in the file system — each-time I transfer image files from camera to computer — named as the transfer-date YYYYMMDD. I wrote a 10-line script to give those image files unique-sequence-names YYYYMMDD-00N.ext.

So when I mistakenly copy into the wrong folder, it's obvious which image files don't belong. So I don't need to delay while I think of the best descriptive folder name. So I don't need to sort yesterdays photos into a different folder than todays photos.

Secondly it's a matter of deleting image files. I take a look with some viewer app and use the file system to delete whatever doesn't seem worth any more attention.

Thirdly whatever trial photo software is available is probably good enough to start learning.

most importantly a RAW file hasn't been demosaiced, ie instead of pixels of colors, it's a grid of scalar sensor measurements that, depending on the pattern (eg Bayer) each represent either red, green or blue intensity. since we only know one for each position in the image, the other two have to be interpolated (which is demosaicing)
