Mobile photography does not have to be done exclusively with the iPhone or other devise. I think it also includes using a standard camera (point and shoot, mirrorless, or DSLR). To me it means not using the computer in your workflow. It is about taking and processing an image quickly.
This was taken with a Canon EOS M2 and a 40mm lens. Processed on an IPad. Software used: Snapseed, PS Touch, Pixelromaric and Mextures. I transferred the image wirelessly to the iPad.
