Comment on Baby sized bolete of some sort
ChaoticNeutralCzech@feddit.org 2 days agoThe processes such as colorspace conversion that a well-calibrated camera uses by default are to make its images closer to the natural ideal of what an image should be based on human vision. It’s worse in some ways (dynamic range) and better in others (telephoto resolution). I get why you wouldn’t consider focus stacking artificial because it’s effectively simulating what our brain does automatically, but it’s intentional photo manipulation like the old technique of dodging and burning.

It is not about colorspace conversion. Most color cameras today use a bayer filter: en.wikipedia.org/wiki/Bayer_filter . The camera captures 3 almost-overlapping images, one green, one blue, one red. Using data from these three images, it calculates the red,green,blue values for each pixel. This combines a physical technique (the byer filtering) with digital software algorithms to produce the final image.
In focus stacking, one generates a set of overlapping images while scanning the focal plane. Software is then used to combine the in-focus slices to produce an image that is in focus. So, again, we combine a physical process (movement of the focal plane) with a digital processing method.
In the first case you have a technique that has been implemented at the hardware level by camera sensor engineers. The second is a technique that is implemented at the photographer level. I see both techniques as equally ‘artificial’. In the first case the filters scan through colors. In the second case the focal plane is scanned. In the first case the people who developed the camera firmware did the work of automated processing, in the second case the photographer needs to do the processing themselves.
I don’t mean to debate your definition, I just wanted to jump in and share my perspective.

Yes, I know how Bayer filters work. And there is almost always some colorspace conversion because the color filters are not ideal, not to mention other math like WB.

Ah, alright! My reason for describing the details of the process was primarily to emphasize the parallels along the processing chain between different techniques.
I am curious about how you draw the line between ‘artificial’ and ‘not artificial’, hope you don’t mind me asking.

Interesting examples, we’re really splitting hairs here. Maybe you’ll catch me contradicting myself with my idea of “artificial” as “deliberately going outside what is normally possible with the technology or challenging the realist nature of the medium” and I’ll learn a lesson!
