It would be rude if I did not answer RSL.He did me a special honor leaning over my photos.He spent a lot of energy trying to convinced me that some photos do not belong to the ''street photography",although, I did not support this.In the same time, I feel guilty for not answering everyone but it would be a grueling English exercise.
So,about ''that's very virtuous...'' ,it can be easily be proven that in ten years,I have been here,the vast majority are made up of my shots and not discussions about photography.
As for the assumption that ''street showcase'' is not the same thing with ''showcase of a street'',I do not know the subtleties of this language,but, I think that my teacher would have sanctioned me if I had said that these two expressions are not equivalent.That does not mean I want to share the misunderstanding of the language with my teacher,it is only my fault.In fact I do not bother anyone with my photos,but,looking at Yours I am not sure You are following H-C Bresson,which does not upset me at all,I am really glad.
Thank You very much.
