Composition is a nuanced and subtle thing, and any single landscape scene can give you a wide variety of possible images. If composition is something you struggle with a bit, this excellent video tutorial will give you some helpful advice for how to compose your landscape images.
Coming to you from Chris Sale, this helpful video discusses the process of composing landscape images. One thing I always think is important to keep in mind is the fact that you can take great landscape photos at longer focal lengths in addition to the more traditional wide angle shots. Of course, many scenes simply emanate grandeur on a large scale, and as such, we often default to something like a 24mm or 16mm lens to try to capture them all at once. There is not anything inherently wrong with that, but at the same time, try not to miss out on a wealth of potential images to be had by zooming in. Carrying a longer zoom lens like a 70-200mm f/4 (you do not need the extra weight or cost of an f/2.8 for landscape photography) can give you a lot more versatility. Check out the video above for more.
