Fujifilm X-T2 RAF file problem in RawTherapee

(Przemysław Wiktorczyk) #1

Hi All
I have problem with RAF file in raw therapee (check picture):

  • left top:RAW Therapee
  • right top: Fujifilm X RAW Studio
  • left bottom: Faststone Viewer
  • right bottom: Adobe Lightroom

Photo in Raw therapee is more dark, and not sharp. I have no idea what happend? This is the same picture in different programs. I’m new user of Fujifilm XT2.

By default RawTherapee applies expsoire correction. You can turn this off by clicking the “Neutral” button in the Exposure tool.

To my eye, the RawTherapee version looks the best.

Unfortunatelly clicking neutral on picture don’t change anything. Thumbnail looks ok (after right clicking->clear profile). With other RAW (Canon or olympus) I didn’t have problems.
I tried also compressed and noncompressed raf.

I may be wrong, but I think that FastStone Viewer and Lightroom catalog preview will just display the jpeg that is embedded in the RAF file, while Fujifilm X RAW Studio will show the RAF file as processed using Fuji’s software version of the style (film simulation and other settings) used to shoot the image (i.e. it tries to reproduce what the same look as the embedded jpeg).

So, not surprising that RT does display a different look, it shows the raw file processed with whatever default processing it is set to use.

EDIT: I was wrong on Fujifilm X RAW Studio, it actually shows the image as processed by the cameras hardware, applying the same style as the embedded jpeg.


Hello @Przemyslaw_Wiktorczy,

Please upload your RAF, for instance using https://filebin.net/
and tell us the link, so that we can see what happens.

Have fun!

@Przemyslaw_Wiktorczy upload the raw file using https://filebin.net/ else we’re only guessing.

@Przemyslaw_Wiktorczy do you have a color target? If so, you could help improve color fidelity for your camera by sending us shots of the color target:

@Morgan_Hardwood I don’t have (I guess)

@Przemyslaw_Wiktorczy I see in your screenshot that you’re using RawTherapee 5.4, that’s good. The default processing profile in 5.4 automatically makes the raw image look like the out-of-camera JPEG. This profile is called “Auto-Matched Curve - ISO Low” - are you using it? The profile automatically activates the new “Auto-Matched Tone Curve” tool. If you upgraded from an older version of RT then you’re probably not using it - I recommend you delete your options file so that you use the new defaults. You can of course activate the “Auto-Matched Tone Curve” tool by hand.

This is what your raw file looks like when using the auto-matched curve:

Odd bump in the lower end of the curve, you can remove it to lower the dark tones.

Lastly, your RAF file contains two embedded JPEG images, one is a thumbnail and the other a large preview.

I uploaded both the embedded JPEGs and my PP3 back into your filebin, https://filebin.net/eodjgmz76xjpczgd


Hi @Przemyslaw_Wiktorczy and welcome!

Thanks for the upload!

To me, your image looks just fine in RawTherapee.
Nothing to complain about the sharpness either!
Please follow the advice given by Morgan, above,
then open the image in RT and enlarge it to 100% (1:1)
and see for yourself.

The X-T2 is a fine camera (even better than my favourite, which is the X-T1 :slight_smile: )

Have fun!

Yes it is better! :smile:
I had the X-T1 before, now I have the X-T2. I find myself almost never needing to sharpen my images now.

Thanks, colors are better, but one more thing (please check link).
First picture is a screen from RAW Therapee, second from fastone viewer.
Second is sharp, first not at all. The same was earlier example with lightroom

(Sebastien Guyader) #13

@Przemyslaw_Wiktorczy as I said earlier, FastStone is showing the embedded preview JPEG, which has been sharpened in camera. In Rawtherapee, sharpening is not applied on the zoomed out preview.

(Przemysław Wiktorczyk) #14

Ok. I understand :slight_smile:


Your upper left is sharp.
I kindly wonder if you perhaps mix-up “sharpness” with “contrast”?

Have fun!
