Yes, it's true that most people who cannot afford to buy SP with fiat or other cryptos need to form connections and try to get upvotes.
I have done a couple things a long time ago around this area but I am less technical and more 'feel' based as a photographer. It has limited range.
It is patently obvious from looking at your photographs that you know how manage light and basic settings like shutter speed, ISO and f-value and use them to get the desired effect. You clearly understand composition and have a pretty good handle on what looks visually appealing even if you lack the skill to explain it well. Most importantly, you have good ideas. You know how and when to deviate from established aesthetic rules to create the desired effect. For example, you once posted a photo of a tram or a train. The picture was slanted which was the correct choice in that case because it enhanced the sense of movement. You also know how to use long exposure to the same effect. Maybe you're not the guy to talk about the technical stuff in painstaking detail but you have plenty of good ideas you can share. Any community of photographers on Steem would welcome a very good photographer like you with 20,000 SP with open arms.
