Cannot access full sensor dimensions on Fuji X-T30

[fschhh (Guillaume)]

I am using RawTherapee 5.8 with a new Fujifilm X-T30. The image dimensions seen by RT are significantly smaller than what is accessible in Darktable or even in the JPEGs processed by the camera, even if I set the demosaicing border to zero. The pixels seem to be cropped at the bottom only.

The dimensions are:

• Darktable 6384x4182 [6384 seems wrong, there are certainly not 146 pixels more in width than in RT]
• camera JPEG 6240x4160
• RawTherapee 6238x4126, or 6252x4140 without borders.

Could it be a configuration problem because the sensor is recent? Is there a file I can modify to change this?

Don’t know if this is relevant, but @Morgan_Hardwood had posted something about this a while back:

Beginner - How do I get pixel dimensions to match?

Your starting assumption, that your “raw files are 4928 x 3264”, is incorrect. The sensor contains a certain number of photosites, this number does not change. But these photosites are not pixels, and the data from them needs to be translated to arrive at what we called a pixel. http://rawpedia.rawtherapee.com/Demosaicing The image size discrepancy depends on how the demosaicing algorithm handles the information from the sensels (photosites) around the edges of the sensor. Some programs don’t…

I’m not sure why you’d be seeing the discrepancy you’re seeing as you describe it, though. Perhaps it’s due to the newness of the sensor as you’ve said.

Yes, I saw this message about discrepancies, but it should result in RawTherapee seeing more pixels than there are in the JPEG, not less.

I should have looked through the forum more before posting, the answer was already there. It’s a known bug that will hopefully be solved in RT 5.9.

Oh, good find! Glad you found that it’s known.
