Alright, if we use your work as an example I would say that you generally use focal lengths of 50mm and longer and most of the time shoot wide open and tend to compose off center (just taking guesses here
🙂 now you could do far more than that but lets just use those points as an example). Shooting like that is a process which you have knowingly engaged in, in order to create photographs that look the way they do. I'm sure you have an understanding that your photographs have shallow DOF and you are purposely using your camera in a way which obtains that effect. You are applying a process.
If we were to look at a more intense process, say Ken Kitano's "Our Face"
http://www.ourface.com/english/works/ourface.html we would see there are many more steps.
That involves taking many many portraits on 8x10 b&w negative (choosing b&w film over colour is also a process, and also all other shooting conditions are each a process), developing them, laying them out on a lightbox and rearranging them so all their facial features are aligned, taking another 8x10 of the lightbox and negative, developing that one, then printing that photo as the final result.
There is a lot more 'process' there. Now it does not make his photographs any better or more significant to any other artists out there who are producing great work, simply because he went to such efforts. But if you understand how he has done the work, it then holds much more significance than simply being a 'pretty' photo. It is understanding that his photos look the way they do because he did all that, and only because he did all that.
Hopefully I'll cover Roger here as well. Now it is not necessary to understand another persons work, you can write it off as 'pretty' or 'meaningful' for whatever personal reasons you have. But if you also fail to understand your own work, can you call yourself an artist? I think there is another thread happening right now with the question "do you understand why it is good?" and that is very much what this entails. If you do not know why your photo looks the way it does then you have not payed attention to the process in which you arrived at that photo and therefore that photo is only good by chance (chance does play an important part in photography, but I doubt there is anyone who would argue that a photographers skill and 'eye' are essential to a good photographer and that continuous good imagery cannot be created by chance alone). However, if you intentionally engaged in a process to create a photo that would look a certain way then you have the right to say that it was due to your efforts and imagination that this piece of art is good. 'Intention' also allows for the photographer to communicate to the viewer.
This is where it is also beneficial to try and understand other peoples work. That is because if you can view their works, understand the process and what the artist is trying to communicate then you have seen beyond the photo as simply being 'pretty' and a photo can develop depth personally for the viewer.
However, no one can be forced to understand the process, even one's own work. Though in my opinion, no half decent photographer falls into that category. You have to recognize that there is more to it than simply "focus and it will be sharp" and that it is most certainly MORE than "only the final image matters" because a photo looks the way it does due to the processes the photographer applied to create it. ///Fin.
