This video however is chock full of plein air painting tips. This is the video I had originally watched then fell down the rabbit hole to the previously mentioned video. In this short video the artist, Bryan Coombes, explains some things about plein air painting that took me a long time to figure out on my own. For example, the details. Those are going to change with the light so don't sweat them. It's only about 5 and half minutes long and half way through I thought to myself, if only I had watched this before I first tried to plein air paint.
Give it a watch, he gives good tips on painting in general so if you're not interested in plein air painting you can still get something from it.
