So thus is my pursuit. To learn and develop a command of the skills that would allow me to have or convey a particular style, unique to just me. Everyone has a different "eye" or viewpoint, thus the way a person captures, produces, and presents a particular image or imagery should by default be unique.
As a young child, I started out as an artist, using paints, pastels, charcoal, and other media. My (late) aunt was a high school art teacher, and she used to always remind me (and at times, scold me) "ALWAYS sign your work. A piece is not finished until you sign your name to it." It still rings with me to this day. And while putting a watermark or some other hard text digital imprinting would work as an identifier, I seek something else. I want that identifying style that would make identifying my work undeniable.
I have a long long way to go. But I am having a great time on the journey.
Great point and something to strive for. However, I often see photographers who have an identifying style, but it's a boring and monotonous one. Every shot looks like a carbon copy of another. To truly master what you mention, you should be able to have enough variation so that each one is more of an extension and continuation of your own style. Bring that style to each of your photos -- do not try to take a photo in order to match one particular style. If that makes any sense.
