I didn't tether either. I have a feeling the blog post is a little out of date, as I had to more "adapt it" than "follow it to the letter".
This is kind of the blind leading the blind, so hopefully one of the experts can chip in and confirm. However to get you going, here's what I did (on Linux): 1. Set manual focus to closest (to more or less guarantee blurring) 2. Set manual exposure mode 3. Set picture mode to RAW 4. In the menu set the ISO stops to 1/3rd (because Auto ISO uses all the stops - mine often picks 500 in low light as opposed to the "normal" 400) 5. Set ISO (first on mine is 80) 6. Hold the camera close to a lightbulb so the lightbulb is in one half of the frame 7. Adjust the exposure so the other half of the frame is as dark as possible while the lightbulb still remains as brightly exposed as possible 8. Take the picture 9. Repeat from step 5 with the next ISO setting This gave me a card full of RAW images at the various ISO levels. I grabbed the git repository (you don't have to compile, you just need the tools) then went into the tools/noise subdirectory and literally just dumped all the RAW (RW2) files in there Then I ran ./gen-profile -d . This goes through all the RAW format images it finds in the current directory and does all the magic for you. As far as I can tell, the instructions about setting a flat colour profile etc are out of date as I think the script now does all the hard work for you. This was successful and created a copy of library.db so I ran darktable --library ./library.db And the profiles appear as presets in the denoise (profiled) module. (note: they appear as presets NOT profiles, I think they only appear as profiles when the developers have coded them into the application itself) Again, if you don't get the results you expect, I found that you have to export the image. Far as I see, darktable only does like a "mild" denoise in the darkroom window. (If it's an option somewhere to render the adjusted image at full quality as if exporting it, I'd love to know it - it may be CPU intensive but Apple's equivalent software seems to manage and obviously caches the preview until you make further adjustments) (comparing the application to Aperture is intended as a compliment, by the way :)) HTH On 24/02/14 16:00, [email protected] wrote: > Hi list, > > I would like to do the same for my LX-5, but I can't make it work > tethered... so I was starting to take the photos manually, but in the > blog post I couldn't find instruction on how doing it (how to name the > photos, for example, if I have to preprocess the raw with dt to jpg with > raw-linear profile of it's included in the script, etc.). > > Could someone post the step-by-step instructions to generate the > profile when you can't tether your camera? > > Thanks, > Romano > > > PD Deryk: thank you, by the way! > > On 2014-02-24 09:31, Deryk Lister wrote: >> Noticing that there weren't any noise reduction profiles for my LX7, I >> grabbed the latest git repository and followed the instructions here: >> http://www.darktable.org/2012/12/profiling-sensor-and-photon-noise/ to >> create noise profiles at all ISO levels. > > ------------------------------------------------------------------------------ > Flow-based real-time traffic analytics software.
