The notion that it is perfectly ok for film to render only the skin of middle class members ok is already discriminatory, regardless of any question of racism - it implies that film should only be used by the middle class to depict their peers...
Except that it was actually you and not I who even introduced the term "middle class" into this discussion; which I also thought was discriminatory of you, not to mention a limitation upon my original statement (why did you exclude "the upper class" - did THEY not also buy film - or portions of "the lower class" who could also afford film ?), but I wasn't going to raise this as an issue. What I said is that companies produce products aimed primarily at the people who are most likely to buy their products (which certainly means those people have to be able to afford their product in addition to any ancillary costs).
I did not even say that this is "OK" (though I certainly think it is), only that it is not racist; as I suggested, it is simple marketing. This IS certainly "discriminatory" in that it is discriminating a product's features and attributes towards the market most likely to buy it - so, good grief ! You still haven't explained which companies don't do that, and why you believe they should NOT do that ? I agree that Rolls Royce not making a car for people with no money is "discriminatory" - so what have you actually proven through gleaning such an admission ? It is an entirely specious argument you present. As I suggested, this is not an example of racism at all. You have stated that it IS still "institutionalised racism and more" without having presented the slightest explanation as to why or how.
You are also very loose with your words such as when you state that there is an implication the film "should ONLY be used by the middle class to depict their peers". There is no such connotation, let alone a denotation. It simply means that the film is at its BEST when taking a certain type of photograph; the type of photograph the manufacturer's market research has determined is the most likely to be taken by those people who buy their film. They can however take photos of other things with it. So, why is this wrong ? You have yet to state why this is an example of ANY form of racism, let alone "institutionalised racism".
You have also not yet responded to my question as to why you believe that stating the middle-class of America in the 1930's was predominately white is racist and factually incorrect. Even if I was to ignore that it is eminently likely you were attempting to accuse ME of being racist (merely because you disagree with my opinion) without any supporting argument, your entire contention of "institutionalised racism AND MORE" relies upon this statement being factually incorrect. So I ask you again: In what way is it an incorrect statement ? I'm not holding much hope as you keep changing your argument or introducing different arguments to avoid answering any of these questions, but still ... they are pertinent questions and you can only avoid them by misreading other people's posts, making specious arguments or resorting to ad hominem attacks for so long.
What is the assumption that the middle class is white and does not have dark-skinned friends, if it is not institutional racism?
Why is the middle class being predominantly white (not entirely white as you erroneously suggest) in 1930's USA a racist "assumption" ? Why is it not just a simple, honest to goodness, actual fact ??
Who said anything about a racist assumption that these white middle-class people don't have ANY dark skinned friends ?? Given the levels of racial segregation in 1930's USA, it would probably be fair to suggest white middle-class people generally had MORE white friends than they had dark skinned friends, but so what ? The argument is that Kodak/Polaroid made their film work BEST (not exclusively) for a majority of their users, which you (unrealistically) argue is racism - or even a racist belief on Kodak/Polaroid's part that white people couldn't have ANY black friends. Good grief again ! See how loose you are with your words, your thoughts, and your comprehension of other people's arguments ?
