I really like Ara Güler's work, my late wife had met him quite a few times through her work.
However, I think what I find disappointing is he was not using the best films available at the time, so I'm (maybe) over subjective, but it's noticeable in comparisons..
I am at a loss, unfortunately. BTW not sure if he identified as "Turkish".
I won't take the thread too Political.
Here in the UK, I can claim my Scottish Heritage, but my wife objected to her Turkish ID card stating a religion, one she hated, because that was/is the default.
Güler was of Armenian descent, I know from talking to my late mother-in-law (born in 1923) that her childhood was extremely difficult. She could not use her Greek name at school or in public, or use the Greek language in public. It was far worse for Armenians.
I will dig out mu Güler book tomorrow and have another look.
