This site's charter claims that the following are on topic:
- photographic processing or retouching
- using photographic equipment
- techniques and best practices
- history of photography
- photography in society
- improving an aspect of a photograph
In practice, the questions this site actually gets and responds to, beyond the very basics that we've really already thoroughly covered (exposure, depth of field, focal length) are mostly:
- what camera to buy?
- what lens to buy?
- how does my software work?
- how can I measure things with my camera?
- robots, robots, robots!
- copyright — what's up with that?
- what does my camera manual say?
- what instagram filter is that?
- what magic button should I push to get good results without work?
- my camera is broken and can you please tell me it isn't?
Now, these are all fine questions, and most of them are on topic. But they're not even close to covering even a tiny fraction of the field of photography.
We occasionally get something interesting about how to take a photo in a certain style or with a certain technique, but these are usually hard to get into a format that fits the site well. We also sometimes get "how can I improve this", but that's even harder because the site doesn't provide good guidance on how to narrow that to a specific issue.
In reality, even though they are listed explicitly, "history of photography" and "photography in society" are right out, as well as large swaths of things which are on the plain face of it about photography. As someone graciously summarized for me:
You can scream that such questions are interesting until you are blue in the face, it won't change the fact that you seem to be the only one here who believes so.
So, this is a serious request. Please rename this site to "camera-gear.stackexchange.com". It can have all the gear questions, and sure, all the "I want to use a camera to measure the size of a room" and similar questions. Then, we can migrate the questions actually about photography to a new site named photography.stackexchange.com, and make it clear that yes, photography is on topic here.
That can't be done when this site is here squatting on the topic. I mean, imagine if https://cooking.stackexchange.com/ only allowed questions about ovens and pots and pans and knives and freaked out when people asked about preparing food? We're in that situation here. Time to stop it.
