Software conversion RAW to other


I was running a stand alone Pclos PC for several years until I bought a DSLR camera. I tried a couple of programmes but ended up reverting to Windows so I could use Lightroom and PSE.

I'm still interested in Linux for it's stability, and would love to go back to it.

Just wondering if Linux photography software is any easier to use?

Thanks

Lightroom and Photoshop are the "big boys" in image processing and Adobe work with camera manufacturers to keep their "RAW" converters up to date with any new advanced (for example the dual-field RAW in the Canon 5D IV). While I'm sure that there are plenty of linux image editors out there LR/PS are "industry standard" for a reason!

I do all of my photo work via Linux and have done for a long time now. It's easier to compare linux usage for this with full blown photoshop and as with that there is a learning curve. There is a linux equivalent but it involves using several applications according to what you want to do.

I'd suggest you get started especially from raw with Rawtherapee. Most distro's offer it. It's a pretty comprehensive package but wont do local work (select some item/area in a photo and change it). There are 2 options for doing local work. The GIMP or Fotoxx. I'd suggest the latter and the GIMP for layer work. I use Fotoxx a lot. I have my cameras set to shoot raw and extra fine jpg and only use raw if needed. Often I can do what I want to do with Fotoxx and it will do local selective work. There was an option in it to use Rawtherapee for raw conversion. I suspect it does that automatically now if it's about. It makes more sense to open raw files with Rawtherpee though and learn how to get the best out of it. If you can use Lightroom and PSE you shouldn't find that too difficult but don't expect it to be the same.

Fotoxx has a series of video tutorials. I find that decent jpg's straight from the camera can be fixed up in that pretty quickly and easily. They often just need contrast curve, brightness and distortion correction. If noise is a problem I usually use Rawtherapee. That will process jpg's too.

The GIMP can be used for all sorts of things. Some ideas here
https://patdavid.net/getting-around-in-gimp/

Where I probably use it most often is for layer and mask work. For instance some photo's might need different processing in different area. Process 2 even from raw to get their parts as needed - form 2 layers in the gimp and paint the unwanted areas transparent. You will find many youtube video's demonstrating similar uses.

The other useful application is Hugin for building panoramas and distortion correction but both Rawtherapee and Fotoxx offer correction and Fotoxx will build panoramas. It will do all sorts of things actually but hasn't got a pretty interface.

Thanks -- I think I probably need to just "do" it, as I did when I went Linux.

Hmm - basically supporting what I experience so far ..

Try searching for the 5D in this

https://github.com/LibRaw/LibRaw/blo.../Changelog.txt

It may be some time before Linux can make full use of Canon's dual pixel aspect in terms of developing from raw. However it's main purpose in life from reading through the blurb is focus in live view. Like most opensource it will evolve when some one decides they want what ever it offers and can do the work. It might have already been done but finding it can be difficult. It looks like rawtherapee already can. How well - I don't know.

Apart from that aspect there aren't any problems. People can use Adobe camera profiles if they want. Those don't always appear as soon as a camera comes out either. Odd fact. it's not unusual for people to prefer the profile built into the opensource raw conversion libraries. The rate those appear at varies.

Yet another is coral aftershot pro. I only found out that it supported layers and how to adjust brushes shortly before the trial period ran out. Looking at the site now the tutorial aspect may have improved. When I looked some years ago I found one youtube video mentioning that it had layers and eventually found out how to adjust the brushes in a manual. The only aspect I didn't like was it's curves adjustment control. Too small to make slight manual adjustments. It isn't free but is cheap and available for Linux - not that apparent until download is clicked. I'd probably use it from time to time if the trial period hadn't run out. I don't need it really. I usually look at the jpg out of the camera and then decide which package to use to process it.

If some one wants to post on the web and there are photographers about monitors need calibrating. Linux is well served in this area by this package.
https://displaycal.net/
It supports many colorimeters and is a lot better functionally than the software that comes with all of them. In fact it's better than what sometimes comes with spectrometers unless extra is paid. I install the profile system wide. That makes sure everything is using the same profile. This is a graphical interface for another package that comes with it. The package itself can also be used to calibrate cameras and printer / paper combinations. Both need calibration colour charts. It's pretty easy to find these at a reasonable price too.

One thing for sure once some one has got used to one package they wont find it dead easy to change. That aspect gets worse as the scope of the adjustments offered increases. The software techniques used to do certain things vary too - in other words adjustment sliders etc may look entirely different. Best thing to do is look for the help on them and play around for a while.
