It's been a lot harder with Covid around. Not because everyone's shielding, which they aren't any more - at least, in London where I am, but because everyone is either just out shopping, or being cautious and boring. (At least, "boring" for the purposes of street shots.) I'm certainly not above getting a shot of someone just standing in front of something, but I'd rather get shots of people doing interesting things. And I think it will still be a while before people fully get back to normal.
After lockdown, I had motivation in spades, but inspiration was very slow in coming. So I took out a couple of cameras and my iPhone and just took photos of anything and everything, with little thought about artistic or photographic merit. I started a new album on Flickr titled "Scrapbook" to keep them in. (I publish most of my photos under a Creative Commons licence so that people/companies can use them as stock, so I made all of these CC as well.) I kept that up for a while, and still have 30 ready to upload and over 300 that need processing, tagging, etc. Anyway, it worked. I found inspiration again in the gaps between shooting scraps. And the proportion of keepers to scraps steadily increased. And then came Delta and Omicron and a very much reduced number of people on the streets, so I'm a bit in mid-air at the moment.
One thing I've found that gives me both motivation and inspiration is finding a photographer I've never come across before, and checking out their work, considering how it differs from mine. Today I discovered
Roy DeCavara and straight away I want to be back out on the street, trying new things.
I've also got a back-up plan, for when motivation and inspiration go on holiday, and I can't find an inspiring photographer. I have a book called "The Photographers' Playbook", with 307 assignments and ideas. I don't know yet how good it is because I haven't started on it yet, but there are plenty of other books of this kind, some of them a bit cheaper than the £20 that this cost. And I bet there are a lot of websites with similar collections of ideas. For example, at some point I plan on picking a random image on Pinterest and checking out the owner's account, and then surfing around from there, picking up ideas and inspiration.
I hope some of this is useful, or at least that it kicks off some ideas.
Thanks for the mention, George. (He's being too humble, Tom...
) There are quite a few accomplished street photographers on TP, and a lot more on POTN which I frequent. I'm not going to name any names because I'll almost certainly leave someone out. But it's worth checking out these threads for inspiration:
