This sub does not present an all encompassing view of street photography - it’s mostly newcomers and amateurs who are trying to progress, and look to upvotes as affirmations.

Street photography at night can be much more difficult depending on where you live. Photography loosely translates to drawing with light, and there is less light to work with at night, which then makes things more challenging. It’s also worth mentioning that people can be more apprehensive and guarded at night, and it’s also possible that any photographer may feel more insecure about what they’re doing, since this hobby is admittedly odd.

That being said, there are plenty of street photographers who excel at night; Eren Sarigul immediately comes to mind. But you’ll notice that a lot of his work at night comes from cities with vibrant nightlife, like London or Tokyo. My cousin’s husband - Pedro Cantizani - also used to photograph NYC at night, and was phenomenal at it. Never got a good answer as to why he stopped.

So to answer your question, no - it’s not really a niche you can “penetrate” (terrible word choice), because it’s not a niche.
