This question was posed on the LightRoomKillerTips.com blog and it made me think of how I view my work.
Here is my response. It is my personal opinion for how I view my own work and it is not a reflection of how I view the work of others. Photography is a very personal passion of mine. I still learn from others even though I may not find their process applicable to why and how I create images.
When is enough, enough in post processing?
To me, photography is a medium for artistic expression. It is the tool that I use to create images that speak to me; visually and emotionally. I use photography to express how I visualized something and attempt to convey how it made me feel at the time. Sometimes I also impart the emotion that I feel at the time of post processing. If the image and the feeling is fresh in my mind then the post processing more accurately reflects the mood at the time of capture. I also experiment with several variations of an image and may keep them all because they speak to me with different voices.
The amount of post processing may vary from very slight manipulations of contrast and sharpness to complete blurring effects, black and white conversions, and duotone applications. I also like to shoot a lot of HDR and I may vary the tonemapping from very subtle to completely surreal. I refuse to put a box of limitations around how I work with images.
I also believe there is and will never be a "pure" form of photography since there is not yet a way to capture what is precisely inside the human brain. Photography has always been about manipulation and processing. Images taken with a view camera and processed as a tintype will always be a different representation of the same image that may have been taken with an ISO 400 Black and white film in a 35mm camera shot through a red filter. Both images are manipulated in different ways. BW film processing in the darkroom is also a manipulation that depends on developer formulations and dodging/burning artistry during enlargement. Ansel Adams was one of the foremost post-processing masters of the film era.
