For my get pushed challenge of a monotone but not b&w shot. Hard one! But I didn't find something better :)
Anyways, I will not post tomorrow I guess - I will visit the Olympus Photography Playground in Berlin, I have no idea what that is actually but it sounds fun and I guess you'll be able to take some awesome pictures :p
Beautiful processing, Jule! Your monochrome gradient works very well with the flower you selected. Love what you did with it. Have fun tomorrow! I hope you're able to get some great photos to share when you return.
