I have no idea if using a saw up on a scaffold might be another occupational health and safety hazard or not - but I was out taking photos of the guys working on the building site next to the office again just to make sure I'm comfortable with grabbing people shots with my new camera before the wedding. Is this sharp enough... I'm not too sure... the edges are slightly fuzzy and I don't know if that is due to the vibration from the machine, or due to me. So I'm thinking I should try out ISO 200 in order to double my shutter speed.
