The more and more time I spend around photographers, the more I get familiar with the lingo and terminology they use on a daily basis. A JPEG, or a PSD file is nothing that I’m a stranger to, but some of the more advanced acronyms and symbols, I need some more getting used to. This collection of jewelry from Photojojo might just help. Photojojo’s Camera Lingo Necklaces feature laser-cut acrylic words and symbols on an 18″ silver chain. Designed by a graphic designer/photog, the lightweight plastic icons have the kind of sharp angles and crisp edges you only get from lasers. It comes in 4 designs: JPEG, CR2, NEF, and a no-flash symbol. Perfect gift for photo geeks.
