#000000 & #FFFFFF
Macro of one of the roses in Shinjuku Gyoen Park. It was midafternoon and the sun was harsh. Bad for landscapes, perfect for high-key macros.
(thanks to takejiro for the final critique)
For those wondering about the title:
#000000 is how you represent Black in hexadecimal (for a 24-bit rgb color space)
#FFFFFF is white.
