Love the colors! But I'm curious: why did you choose to shoot this at f/22?
Funny you should ask, my friend.
I asked myself this exact same question while sifting through my archives to select this image, today.
And the only honest answer I can give is.........inexperience. I was so concerned about having everything in sharp focus, I went way overboard. In hindsight, I should have used something closer to f/5.6 or f8 and lowered the ISO, for a cleaner image. I know a bit more about difraction at high f numbers now, than I did 6 years ago.
I guess I'm lucky the image came out as sharp as it did considering the diffraction that could have occurred at f/22.
Great question !!!
