Hey Dom,
You can quickly narrow that list - you can just pop open the Photography category on themeforest. You’ll get the list down to 266. - Searching for Photography is going to return themes that just have the keyword Photography somewhere in there, and a lot of those themes aren’t that good for real Photographers.
When curating a list for Photographers, keep in mind - 98% of them aren’t web designers, developers, dev-ops, graphic designers. They have no idea which fonts should they choose, which colors should they use, what spacing should they have between elements, and even how should they structure their site. However, multi-purpose ( best selling ) themes are great for small agencies that work for a lot of clients.
Small agencies can quickly buy a multipurpose theme, customize it to the clients liking and ship it off to the world, and get the next client. For people with experience - multipurpose might be a good thing. For Photographers who have their first interaction with WordPress - I don’t think so. If you want to put out quality information for Photographers that will improve upon their lives - help them get up and running in an eye blink and pick themes that are easy to use, simple to set up.
My plea is this - please, please don’t consider multi-purpose themes as “Photography” themes. I’m seeing this happen all over the internet, but I strongly believe it hurts real Photographers, and in the long-run - the whole WordPress themes community.
Norris.
