Instructions for using Darktable on a Linux system for digital photo processing.
Camera: Nikon D3000 (2009) Laptop: Lenovo U430 Touch (2014) Storage: Microsd card in SD card adapter Eject card from Camera, place in laptop. Create the folder ~/Pictures/
Copy just .NEF from SD Card/DCIM/100D3000/ to ~/Pictures/ Start Darktable, press F11 to full screen Make sure you are in "Lighttable" mode Import -> folder Click folder: ~/Pictures/ Click open Set 3-thumbnail view on bottom slider Make a first pass in Lighttable view, clicking the red x on any that are clearly rejects, out of focus, etc. Look through the entire roll for any corruption, other weirdness. You may have no rejects, and that is ok, this is partly just a sanity check so you can verify the local copy. Switch to darkroom mode, view all except rejected Now go through each image, and give a star level of 3 if acceptable. If you're unsure, don't reject, just give it a 1-2 star rating Feel free to keep all or mark as rejects all. The point is to go through and look at each photo for at least 1 second. The best way to do this is to keep the mouse cursor over the thumbnail at the bottom, then use the keys 1-5 for star rating. Then push space to go to the next image. Make sure the mouse cursor stays over the center thumbnail. Now View all 3 stars and above. Mark as leel 5 if it's the appropriate quality. Now View all 5 stars and above. Then do further refinements, editing, color balancing. To remove a photo, just give it a <5 star rating and it will disappear from the thumbnail list at the bottom. Remember to have your mouse over the photo you want to assign a star rating.
Export to disk the selected images: Switch back to Lighttable view Choose 5 stars and above. Shift-Select all of the 5 star images. On the right side, go to Export Selected The default options are: Target storage: File on Disk $(FILE_FOLDER)/darktable_exported/$(FILE_NAME) jpeg 8-bit quality 95 Click export.
