In the 80's and 90's, I used to sell slides to some small graphic design firms in Chicago. Back then, I used to get $300-$400 for an image and get credited in the publications where the images were used. Now everyone needing images uses stock agencies. The image market is saturated with images from photographers and from, it seems, everyone that has a cell phone. You get $.50 on the majority of images and occasionally sell images for $10-$30.00. Not much for the effort necessary. I get about $30-$50 a month as long as I keep uploading new images. If you stop uploading, there must be an algo that impacts how your images show up in searches.
I have my own Smugmug website, but don't use it for selling. I use it for sharing after initially setting it up for business. I use the Dreamstime income to pay for my website. I tell everyone that wants one of my images, that I will order it at cost for them from Smugmug. I used to belong to a camera club, but, as someone above noted, you really don't advance your skills or knowledge after doing it for so long. I messed around with Gurushots for a while, but that really has nothing to do with photographic skill as it is a game with an income generating strategy that advances your images (of course to generate income for the owners). There are some very talented people on that site, but no quality feedback other than ego boosting. I don't use FB or instagram.
I post here primarily. The feedback here is from people of all skill levels that are genuinely interested in the art of photography and who are interested in advancing their photographic knowledge. You get honest comments from those people based on their skill level.
Whether it is sales, likes, comments, or whatever, we all like to hear good things about our images. We all want to think we are good photographers. Feedback is twofold, it provides us with affirmation of what we're doing and provides a foundation for further learning. What FUN IT IS!
