How do you do it?
Just my long used method I guess. It's all about the light.
I usually find shots I like & then return the following day to shoot it when the light will be at it's best for the angle/feel that I want - in this case 5am, literally just as the sun came up.
About 20 exposures over a 5 or 6 min window, then it's gone.
Technically, f22 at about 4 secs with a .6 ND grad. RZ67/Aptus 65s/65mm lens
