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've recently discovered a love of teaching kids the stuff that I loved when I was growing up - coding and computing. I've started a blog on the subject at daddycoder.com. 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. I also host a round table discussion show with three other great daddy bloggers at www.lovealldads.co.uk.

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.
