>>3645153/r/photography is not worth your time, it's all just shitty articles, youtube videos and gear. For a sub that has 2M+ subscribers it is VERY inactive.
/r/photographs is a spinoff intended as a place to share your pictures. Most of the stuff posted is crap and it's not that active.
/r/itookapicture is the same as /r/photographs but active.
/r/photocritique is meant as a place to get critique but good luck on actually getting a useful one.
/r/analog is for film stuff. A lot of it is memeshots on portra 400 but it's still somehow better than the previously mentioned subs.
