I spent time earlier this week playing with digital mark making - enhancing and printing to A3 a photograph I'd taken recently which included strong abstract marks when enlarged and cropped. I then put the image through the printer for a second time to overlay it with tree outlines which I placed and printed randomly - at least as randomly as I've so far found to be possible within Photoshop Elements print options. I folded the sheet using a simple structure that involves partial cutting into thirds and then a form of accordion folding.
In May I'm going to do Pixeladies Course 3 which with luck will help with this overlaying issue (and many others, hopefully) and enable me to have more control over what happens when I undertake this kind of mark making. If the quality of previous courses with these two ladies is anything to go by, I'm sure it will be excellent.
