Gave a teaching session last night, the guy wanted just an hour to see if could learn anything before committing to a full course.
I decided to do the session on composition and to give a short demonstration on what can be done with Photoshop. He bought a selection of his own images on disk, so we played with a few by cropping for composition, then tweeking levels in photoshop. He took it all in and was amazed at how good his own pictures looked with a small amount of work.
He has now booked a full course with a model in my studio for early next month.
