It could be partly solved by bringing some real photographers together to create a curation account - just as the scientists did with @steemstem. let's say "purephotography" - just for example, I'm sure there are more creative people out there when it comes to finding names.^^

quality photographers could be encouraged right from their introduction post to use that tag for their work in addition to #photography . That would generate a tag with less bullshit/crossover photography, just as there is less BS in #steemstem as compared to #science.

People continuosly misusing the tag for their travel/life posts could be educated not to do so by friendly telling them --> reproving them --> downvoting them & reporting them to steemcleaners for tag abuse
