Juxtas and Doubles
The Juxtas & Doubles really took off when I got into the habit of falling for a BOGOFF deal Jessops had (when it existed) which ended up with me having two prints of everything.
Sorting and playing about with them in the studio, juxtaposing images from different sources and creating new whole images as a result.
The Doubles use the same image. The Sideways Doubles are particularly hard to find.
