I'm always in a fake it till you make it mode, I tried every option, from macro to food.
I got a laugh here! you made nice photos with the trial-and-error method you used. Fake it till you make it mode worked in this situation.
I don't think I have seen a yellow lichen before but I have seen that of white and brown.
Thank you. The only way to learn something is to try new things.
This yellow lichen is the most common here, or at least wherever I've been.
