Re: [Darktable-users] viewing videos in darktable?

Hi Alexandre, I am not a programmer so not sure what I had in mind with the workaround. I guess it would be if there was a way to show other file types (non image) in lighttable mode and then open with the default program. I like Moritz's suggestion for the rudimentary support, I think this is a

Alexander, Thank you very much for a long and thoughtful reply, and for the time it took you to write such a complete response. I am really new to this topic of metadata management and therefore I have had many misconceptions. I always thought that the XMP sidecars just contained the EXIF meta

Play a bit around with the threshold parameter of the highlight-reconstruction module. I just have observed some nice results using LCh recovery and threshold of 0.9, the colors have been a bit wrong (green/magenta instead of blue/white), but i was able to fix this with color correction and blendif

It would be pretty nice to have rudimentary support. As it is my videos tend to languish on the card. - Copy them along with image files when importing from SD cards. - Display a video thumbnail inline with the images in lighttable mode. - Opening them opens the system default video program. O

For gently 'flushing' the area to white, 'global tonemapping' is really the easiest solution. Nice! David On 13-06-09 11:55 AM, johannes hanika wrote: > this works really well, too. i wonder if we should collect all those cool > tricks in a blog post. i prefer `global tonemapping' because it ble

Re: [Darktable-users] Best way to recover highlights that are blown in processing?

this works really well, too. i wonder if we should collect all those cool tricks in a blog post. i prefer `global tonemapping' because it blends in more nicely into the non-reconstructed parts. for clipped regions i still used the reconstruction mode of the highlights module (to get white details

Re: [Darktable-users] Profiled Noise Reduction

Oh right, that was it. Now there is profiled noise reduction and it does appear to work significantly better than using the profiled noise reduction without a profile. I still can't get a usable image because the original is just too out of whack, but DT has done pretty great job. I'm losing a lot

are you trying that with a clean import? dt will not read your exif data again from file if there is already something in the db. try removing it from db and reimporting (maybe close dt in between, just to be sure). -jo On Sun, Jun 9, 2013 at 11:06 PM, Jiew Peng Lim wrote: > > On 9 June 2013 1

exif data comes straight from libexiv2. in case libraw is used to open your image, we use that instead (used to be more up to date). possible that that introduces inconsistencies. i've disabled libraw exif data, let's see if we get complaints. j. On Sun, Jun 9, 2013 at 10:55 PM, HaJo Schatz wr

It may not be that easy, actually. Last time I've checked there was an open bug that DT doesn't interpret DNG EXIF data correctly. Field names are different between eg CR2 and DNG. Not sure what exactly DT makes of it, but I've experienced it doesn't play nicely with DNGs converted from CR2. --

Re: [Darktable-users] Profiled Noise Reduction

yeah, no exif data, no denoising for you. could you copy over the exif using exiv2 from the commandline maybe? exposing the full list of noise profiles will fill your screen and be of little use to anyone else.. jo On Sun, Jun 9, 2013 at 9:57 PM, Jiew Peng Lim wrote: > It hasn't? Last I rememb

I got the same results as Julian. Enabling the hot pixel removal module helps a bit, but there is indeed more noise when using wavelets with color blend mode. It seems to just change the colour of the noise to green. On 9 June 2013 17:51, Pascal Obry wrote: > Julian, > > > I've tried your sugge

Re: [Darktable-users] Profiled Noise Reduction

No, justo tries and it removes some of the blown pixels, but the overall impression is the same. The only difference between the two pictures I linked, is the activation of the denoise profile. BTW, maybe I was expecting a significant reduction in in perceived noise. It's clear that it's doing so

Re: [Darktable-users] Profiled Noise Reduction

It hasn't? Last I remembered, enabling the profile automatically selected my camera and my ISO (I'm talking about .CR2 files). I'm using the Canon 60D. However, the profiles cannot be selected manually. This is where it fails for images that do not have EXIF data, like the DNGs which I extract from

Re: [Darktable-users] problem with noise reduction

Hello Ary, If i denoise your CR2 using the settings in your screenshot, the image looks like your export result. To judge the denoised result you need to zoom in to 1:1. Otherwise the image is downsampled before, which makes the image look different after denoising. For the same reason you need to
