If it wasn't for the extreme grain-like pattern I would not have liked the foreground pearls being so out of focus. But it ends up all working together for me.
I am an old time Rollei w/ rolleinar user and have seen this reticulation before.... never been able to track it down... Al Weber says it is from the evil God Reticula whom you must now propitiate some how...... I don't know how either, but I like the image a lot!
