(1) what you suggest about manipulation is like suggesting that a hand thrown pot is not manipulated between the time it is a lump of clay and water
and it magically becomes a pot. exposure is the same thing ... exposure creates the image, not composition
maybe others do, but i don't perceive life in fractions of seconds or time lapse.
the idea that manipulation can only take place after an image is created on film or a sensor is a fallacy as far as i am concerned.
(2) whatever is happening deep within a computer file is similar to what happens when one manipulates a latent image
to turn it into a negative.
both can be manipulated and often times are. every day on this website people ask questions about
how to manipulate images they have recorded on film so they look a certain way. people ask questions about
manipulating images through burning and doing and sometimes ferricyanide bleaching and other post processing.
whether it is more easily detectable on film or file doesnt' matter, neither media are trustworthy.
there is a saying - believe half of what you hear and none of what you see. that didn't just come about during the digital age.
(1) I hate to be the one to break this to you, but a lump of clay and water is not a pot. Except as an abstract concept in the potter's mind. The lump can be manipulated into a pot because it already exists as a lump. But the pot must first be created from the lump before it can itself be manipulated. Would you pour your hot coffee all over a lump of clay, then try to pick it up and drink from it?
(2) No, it is not. Were that assertion true, then removing an SD card from your digital camera and dunking it into a tank of D-76 would produce a silver-based image, instead of a trip to the computer store for a new SD card. Functionally equivalent does not define physically equivalent. Saying two things are the same because they superficially appear to produce the same results is incorrect. Sometimes we need to be a little more thoughtful before throwing out rash assertions. The audience is listening.
It's incredibly naive to believe that photography only starts when light hits sensor.
Yes it is. But that's not what I said I believe.
I said the
image is rendered when light hits film or sensor. (Let's not leave out film. This is, after all, APUG.) And that in order to
manipulate an image, one must first
have an image. Unless you know something more about the arrow of time than the rest of us.
The process of photography is a much larger superset of activities and processes than just those related to the subset of an image. This superset is where the
abstract idea of a future image can exist in one's mind. But actual physical processes must first render that abstract idea into reality before the final image can, in fact, exist in the real world to be manipulated.
Careful unambiguous definitions and clear thinking do count.
