I know why my first few minutes with Darktable seemed so frustrating–they were all me scrubbing this modal interface looking for things I thought all should be in a menubar. But there are no menubars. While DT has quite a bit of keyboard shortcuts (not discussed today) Those were no help because you have to study the Settings dialog Shortcuts tab…no quick to get started with when you’re used to mundane office software. Darktable is as different from GIMP as GIMP is from Photoshop. Is DT similar to PhotoShop? You tell me.
– select photos in light table mode
– select an action group “basic”
Certainly this is nothing like the GIMP. You do have to scrub the interfaces to find all the gritty little features, but it is more batch-oriented and possibly a cleaner work-flow.
