GB saw the oof knee as a flaw, not me. I said it is annoyingly distracting for me.
I didn't make the same assumption as you did regarding the movie 50 Shades of Grey and Daneland sees no connection between the movie title you suggested and his image
I'd be surprised if Daneland's title isn't a reference to Fifty Shades of Grey and I think Daneland expected viewers to make the connection.
He also he did not expect viewers to make that connection.
I posted my opinions of his image based on how I see it, not on some movie he says has no connection to his image.
However, I'm not certain if a direct connection can be made between the photo and the book. I noticed different shades of grey, which gave me an idea for the title.
