I was playing with all the filters of the Pixlr App and came up with this irrisable iridescent image. I know it is not actually B&W but I thought you would enjoy it.
I took this while watering because a rainbow was dancing one the water. I think it works nicely as B&W too. Cee’s Challenge also has hose water go see it here
I’m going to repurpose this post for Weekly Photo Challenge h20
