I took these mushroom photos with a Canon EOS R5 using a Canon 24 to 105mm zoom lens in full bright morning sun. Though they had yellow and brown some from their pristine condition I think the color from stark white helped the photos.
The first 6 photos are my standard color photos adjusted for printing in Lightroom and the second 6 are black and whites taking me back to my zone system days in the darkroom though these were done using Photoshop.
I think I am headed to doing more black and whites in the future.
