I was asked how the Pigeon project is coming along yesterday by a friend.
So this is where I am at.
I use a Variable Neutral Density Filter on a 70-200mm lens. There are three exposure variables to control – ISO, Aperture, Shutter speed. With a variable ND filter you can pre-set two of the three constraints eg. I set the ISO to 50 and Shutter Speed to 1/2 Sec and adjust the Variable ND filter to give an aperture of around f11.
This means that I am effectively working at around 3 ISO on a sunny day.
A big hello to all the new followers of my little blog this week.
