Advice for a newcomer ?

Look through the photographs of the subject you are shooting. If there are a hundred pages of them, they're going to get rejected. If you're using AI, make sure you take a magnifying glass. That's a joke. Bring it up to 300% to check it out. and inspect every inch of the image, because AI gets everything wrong all the time, and sometimes has to be generated many times. Find a niche and stick to it. Put notifications on for this forum. I have learned so much here. I was new here six months ago.
