This challenge came up exactly when I needed it. For reasons best known to my cameras — ALL my cameras — I cannot get pictures of my spiderwort in their actual color of dark blue. They always come out some shade of pink. It must have something to do with the light and that in the leaf, there is a lot of pink and that’s what the camera picks up.
Since this is a monochrome challenge, I could finally make my Spiderwort their real color: blue. If I could figure out what filter would alter the pink back to it’s “real” color of blue, I’d have done it by now. I have spent hours trying to make those pink flowers the color my eyes see them. Lacking that, here are my monochrome cerulean Spiderwort!
