Dear Mark and Michael
I am quite comfortable with using digital SLR cameras and understand the relationship of F-stop to the depth of field. My main reason for undertaking the workshop was to gain some feedback on composition which is probably the hardest thing to learn from a book. I was not disappointed and your advice prompted me to try some new arrangements and to investigate further the use of my 100mm lens rather than my standard 50mm prime lens. I now plan to practise more. I'll be back!
