Hi - I'm Mark Gatter and I'm an Adobe Certified Instructor. My specialist subjects are InDesign, Photoshop and Illustrator (and I've got the 'ACE' qualification in all these) but there are other programs lurking in the background, too. I lived in California for 18 years and ended up as the Production Manager for the biggest commercial printers in north California, and returned to the UK in 1998.
I've had 5 books published, three of which are about graphic design, the big graphics programs, and printing. The other two are about growing vegetables...which I don't plan to cover here. At all.
I teach roughly half the time, and when I'm not teaching I work as a freelance graphic designer. I'm constantly having things printed, all over the world, or put on websites – which helps to keeps me sharp for my teaching work. I reckon I can take a total beginner, who has never even seen InDesign, Photoshop etc, and get them up to speed in about a day and a half. There'll be lots of stuff they won't know, of course, but they'll be proficient in all the basics they'd need to work in a professional graphics studio.
I invite you to check out my videos and see if you agree!
