John Arnold

I'm the host of PhotoWalkthrough, a free online video show about photography and digital photo editing using Adobe Photoshop and Lightroom. I'm also a photographer, photography teacher and video producer.

I also produce a regular couple-cast podcast with my with Ruth called Parental Geekery where we discuss parenting and geekery. It's really just an excuse for us to talk about whatever is on our minds.

My main business, the one that pays the mortgage, is ticket printing. With my sister and mother I own and run Performance Ticket Printing where we specialise in printing tickets, wristbands, posters and flyers.
