Since some time I've searched photos related apps, to edit and take pictures but I've not found anything interesting in open source... Does someone has an explaination?
It’s the same UX. Not sure how one would be less easy to use than the other just for different nomenclature & things being in slightly different locations.
They don’t have to be exact. They follow the same design language for editing & you can do professional photo work in either.. it took me a couple of weeks to get comfortable in darkroom, but this was over a decade ago. When I oversee folks using Adobe software, it looks close enough.
