I saw an advert for an art nude and boudoir course and figured I'd put my name and money down for it. At first I hadn't appreciated that this was a course aimed at professional photographers, and so I had to get good fast! My initial experiments (with myself as model) are recorded in my practice set: a lot of room for improvement!
Flash on bedside table pointed at silver reflector on ceiling. Manual focus, self-timer, camera tethered to laptop, tighter crop, some post-processing. There are more on Flickr, but the photos in the set are marked "moderate" so you'll need to be a registered Flickr user to see them.
