Leanne Cole, a wonderful photographer from Australia, is hosting a weekly challenge on her blog Leanne Cole PHOTOGRAPHY called Monochrome Madness Challenge, where she features monochrome photos from other photographers.
I took a photo of this wild lilly in my garden last summer. It looks lovely in all the vibrating colors, capturing a perfect summer day. But I find something magical in this b&w version, like I am looking at the part of a secret garden full of mystical creatures not willing to show themselves to an unsuspecting observer.
Be sure to check other amazing photos on her blog. If you want to participate, head over there and read instructions at the bottom of the post. I would like to recommend her blog to any aspiring amateur photographer, there are many helpful posts and tutorials and she is very open and friendly person.
