I am an amateur photographer and have mostly done nature photography. That is easy because you can just go to a public park and take some pictures without talking to anyone.
Recently, I've been wanting to try something new. I'm interested in taking pictures of people doing different kinds of work, anything from working in an office at a computer, to blacksmithing or mining. I would love to learn how to capture photos like these:
Note: I don't want to do this for any commercial purpose, but maybe eventually a blog or something. For now it would just be fascinating.
What I'm wondering is, what is your workflow to getting access to these situations? Some situations are fairly straightforward (kinda like street photography), such as photographing people at restaurants or stores. But what about other less public situations?
Is there a standard practice? Or is it mostly based on who you know (like you have a friend who is a blacksmith and you ask them to drop by and take some photos)? Or is their a sort of documentary-ish protocol for reaching out to people you don't know and somehow making an agreement that you can come by for a day and get a tour and take some photos or something.
How does that work / how do you do that?
There are definitely a huge amount of complicated/custom situations, so not wondering about everything, mainly just in general how you accomplish this.
