Thanks to work of very dedicated people we’re very close to full CR3 support in darktable. However we need a broader set of samples.
Currently we have a basic set available on raw.pixls.us (a very awesome resource BTW) but we need samples in all ISO variants.
NOTE: DO NOT SEND all iso variants to raw.pixls.us! upload all samples with BASE ISO to raw.pixls.us and give here link to package with ALL ISO variants
We need CR3 in RAW and CRAW form: Each camera should have two raw quality levels: RAW and CRAW (please notify me if there are any deviations). I need one file per ISO setting for each quality level. The files must be named accordingly: Canon_EOS_RP_CRAW_ISO_100.CR3 for example.
We need ALL ISO settings: Please note that 1/3 ISO steps are set, i.e. I also need ISO 125, ISO 160 etc. In addition, all these cameras should have ISO L (50) and some HI-ISO values, sometimes referred to as H1 and H2.
We need also all variants of crop mode (eg if you put APS-C lens on FF body): If your camera has an optional 1.6x crop mode, I need all photos for full frame AND with 1.6x crop enabled. Please add _CROP to the file name.
Corect licence (CC-0): Before you take the photos, please enter the license “CC-0” in the camera menu under “Copyright”, i.e. the photos are then generally free.
Correct content: About the scene: Something colorful (so no white wall or the like, no people either, cats are okay). It is ideal if all files depict the same scene. Lens, aperture, etc., it doesn’t matter. But make sure the scene is properly exposed and that edges aren’t black
Sending: Then please pack all these CR3 files as a ZIP file and send me link here e.g. via Dropbox, WeTransfer, etc. (approximately 1.2-1.6 GiB).
All the photos were shot at constant F/8 and varying shutter speeds according to the set ISO. All the ISO range for a total of 30 files for each of the 4 variations: RAW, CRAW, RAW crop 1.6, CRAW crop 1.6.
NOTE: DO NOT SEND all iso variants to raw.pixls.us! upload all samples with BASE ISO to raw.pixls.us and give here link to package with ALL ISO variants
If you’re not sure - just send here link to package with all iso and we’ll sort it and upload all base iso (if necesssary) to raw.pixls.us
Hi, I saw too late that there is alrady a RP upload. In case you need another RP set, here are my samples:
The Windows CR3 codec and the affinity suite show ISO level H2 as 65535, Camera shows 102400 not sure who lies and what darktable should display I named the files _65535.
6240 and 3888 are simply the width in pixels. So what I do next is a simple replace using any file renaming utility (I use double commander but the renaming tool in Ubuntu works as well) and replace _3888 with _CROP and _6240 with nothing. And then obviously Canon EOS RP is replaced with CANON_EOS_RP to get finally to the file naming convention recommended above:
Canon_EOS_RP_CRAW_ISO_100.CR3
If somebody is able to modify the single line exiftool command to make it all more automated, I’m all ears.
