Landscape photography can be a tricky genre to work in, particularly since you don't have control of the light or the elements. There are lots of lessons to learn, and to save you time and aggravation, this great video features an experienced landscape photographer talking about lessons he wishes he had learned sooner.
Coming to you from Thomas Heaton, this excellent video features him talking about lessons he wishes he had learned sooner in his career. Of his many helpful points, the most relatable for me was understanding light. When I first started in landscape photography, I put a lot of attention toward finding nice scenes and compositions, but I didn't pay enough attention to how much light really matters — right down to its ability to make or break an image, no matter how beautiful the scene is. Once I spent the time considering and learning to read the light, and then even learning how to forecast it and predict when a scene would be viable, my keeper rate increased quite a bit. Check out the video above for Heaton's full thoughts.
