other than add add Professional on the bottom of every image you made, you can also paste a sticker written "Professional" on your camera, lenses, filters, flash, blower and camera bag. Not forgetting adding the word "Professional" onto your namecard as well.Uncle catchlights... Printing professional on camera doesn't make it professional...
If not I just add Professional on the bottom of every image I make, means I very pro? :bsmilie:

PS, I'm sure you know what format are these cameras.
