Hi,
Wednesday night there is a huge bike meeting in a nearby town and there will be literally thousands of bike to photograph but I also want to get candid shots of the people enjoying themselves and try to capture some of the atmosphere of the whole event.
My problem is I can never seem to judge properly what f-stops to use to get the right DOF for people faces as I walk around. How does DOF vary with distance to the subject ? is there a rule of thumb i.e. if the subject is twice as far away, the image will have twice the DOF ? or say at 15 feet a good f-stop would be F8 for example. My guess is it's just down to experience with the lenses ?
I only have two lenses for my 350D at the moment a 28-135 1:3.5-4.5 and a 70-200 1:2.8L so I'm restricted in choice, I was only going to take the 28-135 as I'll be going on my bike and as yet I don't have a decent camera bag to put my gear in (I'm also worried about the big lens getting damaged in the crowded streets).
Any advice would be gratefully received.
