Had to cancel an event due to lack of Internet I've been running "photo booths" at vendor fairs and festivals for years, they're very successful and profitable and people really enjoy them. I setup a backdrop and a few strobes, take people's photos, then sell the results. I have on-site photo printers that allow people to walk away with prints in hand, and a code on the back of the print to allow people to buy the digital copy or more prints on my website. My workflow currently depends on Lightroom, with my camera tethered to a laptop with a long USB cable. It's been super reliable for years. So last week there was a big local festival. I paid to book a spot there for my photo booth. Hauled my hundreds of pounds of gear. Picked a prime spot before anyone else got there, and spent over an hour setting up. My hired assistants showed up, as expected. Then 30 minutes before the festival was set to open, I started up my laptop to get the software ready (which I had confirmed was functional and up to date before leaving home).
