Don't forget the pin-hole and "camera obscura"
:) :) :)
After 54 year of photography I've moved on to M4/3, Olympus/ Panasonic only to find I'm classed as a snapper :) :) :) :) :) :)

There's a big difference between digital and film camera bodies, and I'm not just talking about the difference between creating a photo using film or sensors. Old fully manual 35mm SLR bodies are very much similiar and it's the lens and film that pretty much defines the difference between one and another. Yes, there are differences in the shutter material, action, maximum speed, cocking mechanism, weight, grip shape and so on, but if you were to put Kodacolor film in three different brand bodies and attach the same lens on all three bodies, the results are going to me pretty much identical, if not exactly identical.

When auto focusing and auto exposure came along, yes that began to throw some individual differences into the soup, but still it was the lens and film that pretty much determined the final result. With digital DSLRs, it's true that several brands use a sensor made by the same company and yes, that kind of puts those all into the same herd. However, with digital, it's the processors and software that are as different as night and day, if there is such a thing when considering that everyone is trying to get their cameras to deliver an image that is as true as possible to the original scene in color, contrast, etc.

In a way it's a lot like making (grape) wine; everyone uses grapes, fermentation and so on. You have to because if you don't, then it's not grape wine. In some cases, using the same inputs produce final products that are intended to be as different as night and day depending upon whether you want a sweet or dry wine and so on. In other cases, someone in California or Missouri produces a Rhine wine, attempting to copy the real McCoy from Germany. Missouri has topography, soils and climate much like the Rhine valley in Germany and many winerys use wooden barrels and vats (as well as plenty of people with German ancestory to boot.) California has climate and soils nothing like Missouri or Germany and many winerys use stainless steel vats, but that doesn't stop them from turning out some pretty impressive Rhine style products.

I say it isn't important how or what process you use, but rather the final product. And from a personal point of view, if your brand and model of camera does what you expect of it, then that's all that's important.
