Apologies for snipping out just what my reply targets.
I would just like to point out that a desaturated color image, and a black and white image are completely different things. The desaturated color image represents color tones without chroma, while a black and white image renders its values according to the spectral sensitivity of the film stock.
A good example is that with certain B&W stocks the color red might register as very dark, or black, whilst with desaturated color, it would will record as a light gray. Desaturated color images lean mostly to mid tones, producing a look and feel of there own, but are nothing like black and white film and printing, except that they lack chroma. Your desaturated color image is indeed the same as the color image, minus the color.
Maybe I condensed more than I should have. Maybe I haven't experimented enough with both yet/all B&W films/talking out of my ***
B&W may shift a color to one end or the other depending on its sensitivity to that color but I'm not sure that matters as I'm sure there is a film/composition out there that would give about the same tonality as a desaturation of a color photograph
I'm not too sure that any given scene works so much better on one film stock so as to make the same scene shot on the "wrong" stock worthless
I know there is a difference between film and a desaturation
Less of a difference when desaturating towards the look of a film
Film records reflected light but not many people encourage using B&W without filters and I see that process as the same as a person in Photoshop desaturating selectively using RGB channels. You get to much the same conclusion
You use a filter to make the film record the scene the same way as you see it naturally through your eyes. usually, anyways. Both have their own spectral sensitivity. So, doesn't a person using B&W record what is essentially the color image/tones of the color image formed by eyes/brain ..only without the color? Isn't it just a novel way of seeing color then? A much more graphic representation of color.
Even if different films give slightly different results isn't that still basically the same thing? ..a selective filtering only done in film as opposed to the light onto the film?
"The desaturated color image represents color tones without chroma"
"Your desaturated color image is indeed the same as the color image"
You're saying that a desaturated color image gives the exact look of the world if we did not see in color?
Color blind to all
So why don't we just desaturate the color in color photographs if we truly want to see in tones?
why is that not as good as using B&W film? Because we can discern red from green easily in color but in a desaturated image -or on film of a certain spectral sensitivity without filtering- we lose the ability to easily distinguish them.
I'm sorry
I've never gone into the science of either film nor human vision but this is what I believe ..and some of what I wrote up there still isn't making sense to me or elseI know I have to think about it some more or study vision so as to better word it
I just don't put much stock into the notion that B&W somehow shows emotion better ..or black and white can make a certain photo "look" better than if it were in color
I'm pretty sure that if one chose the correct color and B&W film to give them the exact look they desired in tones both would be equally as good for any scene before them
and would look the same only one having color and the other not
?
as in they would both render a tone equally to one another in relation to the others present
?
As for emotion
I would start arguing that smiling/crying does not mean one is more emotional than one who does not
The one is just a much more graphic representation/symbolism of the emotion being felt
etc etc
If you read that and have something you think I should study
I welcome it
