I'm giving an Ipad/Artrage demonstration at a gallery on the 25th June, so am polishing my skills.
I tried this on my pc a few years back, and gave up. Then I watched a glorious documentary about Vermeer this week, so felt compelled to come back for another try.
Doing it on the Ipad was more challenging, great fun, and I think I got an ok likeness. I'm sure I'll have another look and fiddle a bit more.
What a great artist he was!
