Scanner photography + sandwiches = Scanwiches (simply put: "scans of sandwiches for education and delight"). The web-famous Tumblr is the invention of Jon Chonko, a NYC-based designer at thehappycorp global.
Chonko's process, via Gizmodo:
"I clean the glass at the end of each set with Windex and a paper towel but between sandwiches it just gets wiped down. We started with a plastic film when we first scanned but we found that it fogged up when we did hot sandwiches. Straight onto the glass gets the best quality. This is a full time sandwich scanning machine [HP scanjet 4570c]—we have another really nice photo scanner for office use.
??I take the image into Photoshop and do some white balance and color-correction but nothing dramatic. The sandwiches have to look appealing and realistic. I want people who see a sandwich on the site to recognize it if they've ordered it. It's about education first and delight second."
