I have always loved architecture, so I enjoy seeing these images online. I also really like photographing these beautiful works of art. It comes down to angles, time of day (sunlight), and post-production.
It is also important to have a great subject. Los Angeles and New York are filled with beautiful architecture, but I’m sure you can find an incredible building to photograph in any other city around the world.
It’s important to have a wide-angle lens. I use a Nikon 16-35mm for all of my architecture and landscape shoots. If you are shooting from a distance, you could then use a longer lens. The time of day is very important because you want the light to create interesting highlights and shadows on the architecture you are photographing. If you shoot midday while the sun is high, you may not get interesting shadows, but this does depend on where you’re shooting and what the subject is. There are always exceptions to the rules.
Post-production is very important, and in this video, you will see a comprehensive tutorial on how to get that deep black contrast and beautiful highlights.
