If your purpose is to capture a perfect abstract from a landscape scene, you will be able to do it using a good telephoto lens. Apart from just capturing a whole landscape scenery, such telephoto lens can allow you to have a really artistic captures. Here are some things to consider when you are finding for perfect abstracts from a landscape.
If you are using an advanced digital camera with modern features, you will be able to crop the photographs you captured and see if it does the trick for you. Cropping the photographs into different sized may give you different abstracts.
Just pay attention to the image really closer instead of pixel peeping. Eventually, you will be able to find shapes and different tones off your landscape.
If you are looking for the most convenient way to get an abstract out of a landscape, you should consider black and white rendering. As you render in black and white, the entire capture will be simplified and you will see more shapes and solid tones in black and white.
Pay attention to the most noticeable objects in your scenery. You can tilt or rotate the photograph you captured to see if anything good happens.
If you don’t use black and white, try two contrasting colors. Having more than three colors might prevent you from getting a perfect abstract.
