This one's called 'Headache'. I never used to suffer from headaches until about a year ago, but monthly migraines which last three days are now a feature of my life. I guess they're all part of the slide towards the menopause. I'd rather have hot flushes, though!
My original idea with this one was to add weird colour and blur effects to mimic the visual disturbances you get with a migraine, but I think it works better as a 'straight' portrait. I did the initial editing in Photoshop, including transforming it into black and white (gotta love that red filter for evening out skin tones!), and then applied sepia and 'gritty' filters in Picnik.
