Darktable works brilliantly now! But a problem is the (Lensfun) database: I found in one image taken with my Sony RX-100 compact the lens distortion correction for a RAW image was perfect; for another pretty close but not really good enough. Turns out the actual focal length in the latter case was 15mm, while the Lensfun database offers only 10mm and 14mm as choices - and that 1mm difference is enough to leave a rather annoying distortion (in-camera perfectly corrected for a JPEG). So now I'll have to try and build my own lens profile. *sigh* Gathering information... but it's #hammock time now! !photography #Darktable #Lensfun
