Darktable hasn't open my TZ60's raw pictures at all. In LT I can see some pictures in a folder, but double click doesnt open it at all.

History

#1 Updated by Pedro Côrte-Real over 3 years ago

Thanks for the sample file. These cameras have 4 different raw modes (16:9, 3:2, 4:3 and 1:1). This file is 3:2. To add full support for the camera we need one file per each of the modes. Could you change that setting and shoot a raw file in each of the other modes and attach it here?

#2 Updated by Pedro Côrte-Real over 3 years ago

Support for this file has been added in this commit to the current development version (what will become darktable 2.0):

https://github.com/darktable-org/darktable/commit/dea1232a2ef7cb0526b280abef259b1f5c72a7f0

It will be backported into darktable 1.6 so will show up in 1.6.3.

To improve the support you can provide some extra raw files:

1) the other 3 modes as I described before
2) samples shot with each of the whitebalance presets (e.g., Daylight, Fluorescent, etc)
3) samples shot at each ISO level with a target that includes very bright and very dark areas

I think something went wrong there... Presumably you need to share a dropbox link with us?

#7 Updated by Pascal de Bruijn over 3 years ago

It seems the Flash white balance preset is missing.

#8 Updated by Antti Holma over 3 years ago

My TZ60 has not the Flash white balance at all. It's only AWB for flash.

wb_presets have been committed:

https://github.com/darktable-org/darktable/commit/12d05af2016ba75889ec19e555a500affa3cffe5

additional work still pending...

#10 Updated by Pedro Côrte-Real over 3 years ago

The extra raw modes are now supported:

https://github.com/darktable-org/darktable/commit/84a0d55b2f8834a7850ea3d5ec42114f2f6d5ec1

The only missing bit is the noise profile

#11 Updated by Antti Holma over 3 years ago

Is it something I can help with the noise profile? Better pictures, or something else?

#12 Updated by Antti Holma over 3 years ago

The TZ60 support is very fine, only one thing isn't right. The 3:2 has quite bad vignette.

#13 Updated by Pedro Côrte-Real over 3 years ago

All your recent samples seem to have black margins. Do you have some kind of after-market lens hood? Anyway, there's nothing in the raw processing itself that will fix that. You can provide samples to lensfun for automatic correction of color aberration, distortion and vignetting:

#14 Updated by Antti Holma over 3 years ago

I don't have any lens hoods at all. And I use raw + jpg when I take pics. 4:3 is fine, 16:9 is fine but 3:2 does vignette.
This raw picture is a good example.

#15 Updated by Pedro Côrte-Real over 3 years ago

I see very serious black areas around the edges in your test shots, not really vignetting something is really blocking the lens. But anyway the reason for 3:2 to have more vignetting is that it's the actual resolution of the sensor, everything else is just a crop. That's not really something to be fixed by the raw loading. You can apply automatic vignetting reduction by calibrating the camera+lens with the instructions as provided in the link I posted above.

  • Status changed from New to Fixed

Actually for m4/3's the native aspect ratio should be 4:3 :)

However, the image indeed seems like a case of crappy lens. And it's hardly surprising and fairly common on these compact superzooms.

The aspect ratio probably doesn't matter too much, lenses exhibiting vignetting often only do so, at their larger relative apertures.

The sample image you provided was shot at f3.3, which is the largest aperture for that particular lens at that particular focal length. Thus the vignette.

The only proper solution would be to generate correction data for lensfun, as Pedro already outlined. So it's not a darktable issue.
