Played around with my plastic Holga lens. It definitely has its limits and quirks but its still fun.
Owl update: It spent the night in our fenced garden and looked okay this morning. He/she was sitting on top of a log with its parent watching close by in a tree. I checked on it about an hour later and it was gone, no feathers laying on the ground nor did we hear anything to suggest a predator might have found it.
I did chat with the local wildlife rescue center and they told me that young owls can climb fairly well. I am hopeful that all is good as we did not see any further signs of owls today.
I really love the dreaminess your holga lens created on this shot. 6 or 7 years ago I went with some other photographers to a site where owls had nested and several "experts" there said the babies were just about ready to fledge. So maybe your little fellow had done that. With no feathers on the ground, it's a strong possibility that he's made it on his own. Nice shot!
