From my point of view,technique is very secondary. First asking oneself what we like, what empassions us, seems to me the real way to know the pleasure of photographing.
I'm in a périod where black and white takes a lot of space. The editing is limited to a conversion of the image to B / W and work on the density and contrast.
I think the time saving is upstream, I mean the work of selecting images. I erase a lot of images, then I only transfer a few photos to my computer. Another selection is made on the computer screen and I have at the end 2 or 3 pictures to edit.
From the perspective of photographic technique, I am self-taught. I have many shortcomings, but technique comes with time and it doesn't prevent me from taking pictures.
