New to RawTherapee

(Colin Paul Adams) #6

You can open a converted raw in GIMP - there is an export target (provided you have lua support compiled in) provided by a lua script.


Since I started using RT only a few months ago, and the memory is still fresh…
I agree that it can be overwhelming at first. Especially the fact, as you mentioned, that several roads lead to rome. The youtube videos I found weren’t that great in my opinion and I’m toying with the idea of making one to show a basic workflow.

If it helps you, this is what I regard as the basics:
In the Expopsure tab:

  • Exposure
  • Lab Adjustment

In the Color tab:

  • White balance

In the Detail tab:

  • Sharpening
  • Noise reduction
    - Contrast by detail level - This one is optional, but i find so powerfull that i use it almost always

Hi, I suppose Lua is something for Linux ?
Not all people are on Linux :slight_smile:

(Colin Paul Adams) #9

No Lua isn’t Linux-specific.

Hi, Mccap. I agree about the quality of the Youtube-videos. Looking forward for yours.

My workflow for the moment looks like this

In ColorTab : whitebalance
In TransformTab : cropping and lenscorrection
In ExposureTab : Raw opened with Equilibrated-profile. First set exposure correct if necessary. In the first curve adjusting white-point and black-point.More or less contrast.
Adding a graduated filter in the ExposureTab if needed (for skies for example).
Looking to correct the highlights if needed. Setting Lightness.
Adjusting saturation : mostly in LAB in the exposure-tab / sometimes in the ColorTab preserving skintones.
In DetailTab : noisereduction if needed + sharpening.

Some further finetuning beyond the above described basis.

Open (as Tiff) in AffinityPhoto for final version.

Oh, great, must check that one. Thanks.

You’re probably aware that you have a default profile used initially when any raw is opened for the first time. And that you can put what you like in this and save it in your “personal folder”. I have crop set on in my default, so when I need it, I can just drag the boundaries in from the edge, and the annoying cross lines are never present because they’re turned off in the default. And I haven’t had any trouble dragging them back to the boundary should I need to. Hope that helps.

When I first started using Rawtherapee I used quite a lot of the “PreSets” (especially the portrait one’s) and then worked my way through the settings to see how the look had been created.

Now I am more confident I start with neutral and work my way through the tabs…starting with exposure, wavelets, shadows and highlights and I really love the tone mapping.

Stick with it and you will start to love it.

You might want to use the Hald CLUT film emulation ‘plug ins’ they are truly awesome. @patdavid on here wrote a fabulous piece about how to use them. The monochrome film emulations are second to none.

I also use Darktable which is another superb editor and appears (in my opinion), to handle noise reduction and colour management better than Rawtherapee.

When I want to edit a RAW file now, I sort of decide what look I want from the finished shot and then decide whether Rawtherapee or Darktable will get me there. Well they will both get me there, but which one is easier :slight_smile: …If that makes sense :slight_smile:

Anyway stick with the editor it is a steep learning curve but well worth the climb. Check out videos on you tube and yes read the wiki pages. In fact I am probably unusual in that for both Rawtherapee and Darktable, I read the manuals first before editing !!!

Hi I am new to RT as well and I don’t know if it’s there a possibility to generate film grain.
I haven’t found anything …Guys could you shed some light on this topic ? Thanks.

(Mica) #15

I don’t think there is a grain module. You can do it in gimp or with gmic.

(Daniel Nagy) #16

Ok thanks thats what I expected :frowning: it’s a pity, that souldn’t be so hard to implement,just some simple grain filters. They could be used to create real film look coupled with HaldClut film simulation :slight_smile: because now I have to use aditional editor for this …

It’s a bit more complex than you might think at first glance. (Hence @Morgan_Hardwood’s link).

For a long time now I’ve personally used a normalized scan of actual film grain set over my image in an “Overlay” (or “Soft Light”) blend mode. For instance, here’s a nice one I got from Petteri Sulonen ages ago that has served me well (11.5MB):

(Daniel Nagy) #19

Thanks for answer, Yes you are right to use a real film grain overlay is a little more complex…You have to scan different films structure etc … But wasnt’t there a plan for this in the future to actually implement this inside RT, becuse every major Raw converter has this feature so it would be nice to have it :slight_smile: I am just asking . Thanks

(Morgan Hardwood) #20

Nobody is working on that.

(Pat David) #21

The G’MIC project has a neat grain synthesis option using a grain sample as a seed. That might be worth investigating?

(Daniel Nagy) #22

Thanks I will check it out :slight_smile:

(Pat David) #23

Sorry, I didn’t mean to be dismissive if I came across that way. For me, everything usually passes through GIMP for something before I’m done and I have used grain overlays for a long time in that fashion.

I agree that a grain module would be nice (and I’m positive the devs do as well), but it’s really a matter of getting competent programmers and maintainers on-board the project to implement those things. Unfortunately, those types of folks are in short supply - so things are prioritized differently.

(Daniel Nagy) #24

It’s ok Thanks, I am actually a Junior C++/C# developer, but I don’t have much experience. I want to check out the sources just for my personal interest, maybe play with the issue a little bit (it’s distributed as an opensource sw under gpl if I am not mistaken).

Thanks for the info about the topic. :slight_smile:

(I don’t want generally participate to hi-jacks but will still answer this one)

No. This new behavior has been introduced for a single reason : local editing, where users will have to be able to draw outside of the sheet. Yes, local editing is still planned, but delayed due to GUI problem. The core engine will also have to evolute strongly before anything good can be done on this front.
