Fujifilm X-T3 Support Tracking / Discussion

(Isaac “Ike” Ah Loe) #1

So in another thread related to Rawtherapee a user submitted some raws to raw.pixls.us (awesome)

I added a camera support bug here: https://redmine.darktable.org/issues/12346

Making thread to discuss initial support and anything else that might be needed afterwards like noise profiles etc

Note: Rawtherapee dev build actually has initial support now if anyone needs a FOSS holdover for their X-T3 RAFs

Initial comment from a dev: “Needs adobe dng converter release”

So looks like it’s on hold. Can anyone explain this comment and why that is needed first?

The person who left the comment is here, @LebedevRI, perhaps he will answer.

Also noise profiles would be a separate issue. If you have the X-T3, please shoot the necessary raw files for noise profiles. If you can’t process them, post theme here and I’ll process them.

As insisted by @darix, i have checked the X-T3 raws 90 minutes after the camera announcement,
and they decoded fine, but if there is no color matrix, the dt support (as opposed to just the
raw decoding support) can’t be added… And adobe dng converter is where the matrices originate :confused:

Thanks for that explanation!

If you can tell me how to do those I can provide them tonight after work.

It is described here: https://pixls.us/articles/how-to-create-camera-noise-profiles-for-darktable/

Thanks for the tutorial. Couldn’t do it yesterday but I will try tonight. I will see if I can use my bright LED lights to get some decent overexposed whites and underexpose the shutter enough to produce deep blacks.

hey Stefan did you have any luck with noise profiling? may try on the next cloudy day if you haven’t had the chance. Would just using an led behind my dual layered softbox (instead of the sky on a cloudy day) work well for the pictures needed?

By the way so thankful to have the initial support. Being able to pull up shadows has been so helpful since i take a lot of low light punk shows and stuff

I panned to do noise profiling with @darix next week. I have some ideas for stencils I wanted to test anyway :slight_smile:

(Isaac “Ike” Ah Loe) #14

Any update? i have a thousand of low light photos to edit from a garage punk music fest, and noise profiles would be awesome, did you already test out any noise profiles? I may try today i have some black construction paper and some time

(Andreas Schneider) #15

I had an idea for creating a noise profile. I’ve just performed some handicraft. You need the following files for that:

and white.png

and buy thick black paper!

You need to set the lens tho manual mode and focus to infinity. I started at f/1.8 and stepped down to f/4.0 that it isn’t too blurry. Then make the picture dark and make it brighter till the white from the monitor is overexposed, then start creating a picture for each ISO value.

However the result doesn’t look that bad.

(Andreas Schneider) #16

I’ve updated the howto on the website, as the results look great.

(Andreas Schneider) #17

@darix and I just created noise profiles for the XT-3 …

If someone wants to try it:


darktable --noiseprofiles /path/to/presets.json

Nice, the updates look like a really good improvement to making the process easier to follow. Great stuff :slight_smile:

Is it possible to use the embedded opcodes for lens corrections with Fuji raw files? The lensfun profiles are not as nice for some popular lenses, like the 18-55mm.

(Andreas Schneider) #21

Then create better profiles :slight_smile:

It’s an open source project, you can contribute to it …

(darix) #22

Do you know how to interpret the opcodes?
