Often when I’m feeling overwhelmed by a panoramic vista such as we found at Garrapata, I find it much more rewarding to zoom in on the smaller subject - that which I find the most compelling from the whole scene.
Painting waves from life, or anything that moves, is pretty tricky. Waves have the advantage of a repeating movement, which helps, since you can focus on a particular area with each wave, gleaning more shape, edge and colour knowledge as you go.
For subjects that don't repeat their positions, like seagulls for instance, I often take a video and pause it at just the right moment to capture the position, but will rely more on plein air studies for the colour information.
