I really enjoy your photography, as per usual, but this article has a very special content of questions rather very interesting... Thanks for opening up the valves that way and allowing us to inter-relate with you on the subject matter.
Colour is almost like a living thing in itself in my mind and portrays many different dimensions of our relation to the world. It definitely has importance, yet, I would not end my life if I ended up blind. I'd sure miss them though!
I find, in some of your pictures i.e. #5 & #7, maybe even more interest seeing them in black and white than I would seeing them with colours... The subject matter finds a new wealth.
Thanks for the sharing and opportunity to dialogue. Beautiful shots too! Namaste :)
