We were up each morning for sunrise, this was the first. With fast painting to get the colours and shapes of the clouds down before they changed. And a bonus to have a little fishing boat puttering into my scene, I put it in without too much detail just general shape.
I pre mix my colours before the sun has come up and the display starts. Quite tricky as its dark when I'm doing it- I need a light! But helps to be able to dive into the paint once the colours start....I can also tweek the pre mixed to get the colours to match what I'm seeing but its a good starting point, see my piles of mixed paint below.
