The temperature was just above the freezing point which slightly altered the consistency of my paints. They were less fluid and didn’t dry at all even after I diluted them with solvent.

As a plein air painter you have to adapt to these ever changing circumstances. When you know your paints, you can even take advantage of these conditions and achieve all sorts of extraordinary effects. In this case, I was able to make blobs of well mixed color that I wouldn’t be able to do in warmer weather. This particular thing turned out to work very well for the rocks and the trees.
