When you think of focal lengths for landscape photography, your mind likely turns to wide angle lenses, and no doubt, those are commonly used for a good reason. However, using telephoto lenses can really open up your creativity. Nonetheless, they come with their own pitfalls, and this great video tutorial discusses them and what you can do to avoid them.
Coming to you from Mads Peter Iversen, this awesome video tutorial discusses common mistakes landscape photographers make with telephoto lenses and how to avoid them. I am a big advocate of using telephoto lenses for landscape work, as they offer a new perspective that is rarely seen in the genre and that can really set your work apart. On top of that, because landscape scenes are often inherently quite wide, with a telephoto lens, you can often get multiple photos from a single location simply by picking out individual interesting elements. If you have not used one before, definitely toss it in your bag before you head out next time. Check out the video above for the full rundown from Iversen.
