Hello! Long time lurker first time poster. I’ve been into photography since the very late 1990s/early 2000s and been using Darktable full time since 2014. Mostly on Linux but also on Mac OS X, although the latter is seeing less and less use. Trying to interact with the community more, I’m bad at that …
At any rate among my other hats I’m an astronomer and would like to share a couple of photos I processed in Darktable over the last few months. First one is the total lunar eclipse form back in January. Nothing terribly special here, it’s was pretty clean straight out of camera. Just a little adjustment for the highlights on the limb of the moon, levels adjustment to bring up the shadows, equalizer for the details/color and profiled denoise (was at ISO 2000). Shot with a Nikon D7500 and 200-500mm f/5.6. The poor Nikon’s buttons quit working due to the cold (-3°F at the time) but it came back to life after a warm up.
Second photo is of Comet 46/P Wirtanen back in December, also edited in Darktable. This shot took quite a bit more processing. I do like the equalizer module for astrophotos, I used it here to bring up the luma and chroma on the more coarse details to help beat the noise down. Other than that I used profile denoise, some levels adjustments, increased saturation, used the tone curve to bring out contrast along with defringe and lens corrections to help get the chromatic aberrations under control. Shot with a Fuji X-T2 and 35mm prime at f/2.8 and ISO 3200.
I do a ton of other photography too, just wanted to introduce myself and some of my work! Thanks!
