Reddit subs sometimes don't match the content you'd expect from their name (some are very hard to decode for outsiders, e.g. femcelgrippysockjail, gangstalking etc). Perhaps pics was once just pretty landscape photography, but what happens with Reddit is that a sub will start to focus on one type of content that the hivemind wants and then the sub will fracture. You have to go find r/lovelylandscapes if that is what you want. It'll be there somewhere. You landed in the wrong sub.

There is /r/photographs and /r/photography for that.

Maybe you want your personal preferences served up to you without having to work for it?
