One element I have been experimenting with this year is how I apply the initial tone to the canvas. I only recently discovered the correct term for this is Imprimatura. In the past I used to tone on the spot in relation to the mood and sky, sometimes grey sometimes yellow ochre etc. I like to think of it as an intuitive response to the scene and the lighting and just try to imagine what will work well as an undertone. I would then apply some pigment and wipe with turps until I had stained the canvas and left dry to the touch.
I was interested to read that some artists like to mix colour with gesso and tone the canvas so they are ready to go. Anyway I was inspired enough to give this a go. I had 50 8×10 boards and toned half a cool grey and the other half a warm pink colour.
You can probably guess which one this was!
