Searching for style is an interesting task in photography. Why do you choose the compositions and subjects that you do? Are you finding things that please you and sharing them with the world? How is what you are photographing representative of you as a person? How do you recognize your own photos?
In some way, style is unavoidable. It is the result of lots of work. The more work you do, the more you are able to distinguish your style from the rest of the world’s photographs. And it is a world full of images, more photographs than ever before by far. Every day it seems to increase, too.
There are different formal choices you can make that will mark your images as being yours. You could do only black and white or only focus on one color or any other number of ways to say this is your photograph. You can also do this with subject matter.
Your editing has as much to do with it as your shooting. I like to see natural looking light in photographs, so I tend to edit with an aim to having it look as close to the scene as possible. I care about color and want my photographs to show the truest version possible. Other people opt for a super saturated look. The important thing is to have a reason for your decisions. Why is this your style?
Another key distinction with style in photography comes from the use of perspective to achieve depth or flatness. Some photographs (with a foreground, middle ground and background) invite you to look into them as though mentally stepping into a world. On the other hand, some photographs lack perspective and are more for looking at than in.
You also have to choose where along the spectrum between abstract and figurative your work will exist. Some photographers focus on color, texture and geometry and exclude storytelling elements to create a formal viewing experience. Other photos attempt to show you a world, to depict a scene, to tell a story.
It is also very possible for one photographer to have several styles. It is fully possible to create different styles for your work. Different series have different elements needed for their effects.
