For the weather shots, i wait for the conditions to turn what i feel is right for me.
I know roughly what time the sun will set and so I check each evening to see if the sky looks interesting.
Before going out to shoot, if the conditions are right, a recce is a must. As you only have a small window of time and fumbling around in the dark makes it easy to lose equipment.
Ok - now you know what and where you want to be... starts the waiting game....
This evening the skies were all red and looked really interesting and so off out i went.
Here are a couple of the evening.
