I noticed how the popularity of my photobook reviews roughly scales with the popularity of the photographers. That’s bad news, of course, for a lot of photographers, whether they are up-and-coming talent, simply not very well known for whatever other reason or, and this is another factor, well-known somewhere other than the internet. There are two filter bubbles, the one where we seek out that which we already know (which then confirms our beliefs and thus makes us feel good about ourselves), and the one where a lot of stuff simply is not available online. Mark Markov-Grinberg might provide a good example - try to find information online, and you come back with not much - other than, maybe, the occasional image on The Retronaut (where photography is mostly used as some sort of nostalgic novelty item, so that we might be amused by the fact that we’re ignorant of the past). Luckily, Soviet Era now offers a chance to discover the photographer’s work.
