One of the frustrating parts about landscape photography is that unlike most other genres, you do not have any control over the light. Getting surprised by the light often leads to landscape photographers making a mistake that deprives them of worthwhile images, and this excellent video discusses why and how to avoid it.
Coming to you from Andrew Marr, this great video discusses the issue of encountering "bad" light in landscape photography. We often set out with a certain type of light and image in mind, and while we can do things like monitoring weather forecasts to give ourselves better chances of finding what we want, nature does not always cooperate, and sometimes, you are met with entirely different light. That is not a reason to pack up your gear and head home, though. It is possible to make compelling images in any kind of light; the key is learning to embrace the light and make images that it is conducive to, rather than working against it and trying to force another image you had in mind into existence. Learning to do this will widen your creative palette and improve your technique. Check out the video above for Marr's full thoughts.
