Thanks, @pamknowler for loaning me yours last week, and thanks to @pixiemac for encouraging me to get one when you were here last year with yours! Thanks, @taffy for processing tips!
This came out SO well!!! I'm envious of your new lens -- may you enjoy it for many years! The design in this seems abstract but invites me into the image to see just how perfectly symmetrical you've made this. Superb.
@jyokota oh so pleased you have bought the lens! You will have such fun using it Junko! Sorry can't help with the framing of the circle. I have often wanted to clean up an edge. Some of my shots- particularly outside images get a blue edge which I have tried to get rid of without success. Maybe google the question Junko - there is probably a YouTube video on editing fisheye images. Fav for this fabulous image! Have fun!
Great image you could clean up the edge in LR using a post crop vinaigrette if you adjust the roundness and feather you should be able to create a crisp edge :)
