Soft, delicate, and detailed subjects look best when you drop the ISO to 64. In this image, the candy colors and the softness of the flowers really stand out.
One day I came across this cicada shell, dangling from an autumn maple like a summer memory. I used telephoto because the subject was pretty high up. Since I had to point my camera straight up to take the picture – and because shooting on the tele end can cause blurring due to hand movements – I set the ISO to 400 to make the shutter speed faster.
