I don’t know much about photography, but RSS Feeds I love.

There is a fediverse equivalent to Instagram called Pixelfed.
And since it is the fediverse, every Account has an RSS Feed.
So it is really as close to a photoblog as it gets.

Here is some random example: https://pixelfed.social/Laszlo

You could look at some of the known Servers here: https://pixelfed.org/servers
And then dig around until you find a profile with photos you like.

Other then that, here is a blog of a guy at the south pole who writes interesting stuff. Each blogpost features many photos that you wouldn’t get to see otherwise (I guess. I don’t know actually. But it is a sensible guess, I guess): https://brr.fyi/posts/last-flight-out
