Thanks all for your constructive comments.
Maybe I went a bit too fast on that one.
When the theme came out, I knew exactly which subject I wanted. I knew I wouldn’t have much time this week to shoot hence why I am only replying now so I wanted it out of the way quickly.
However, I was happy with the photo I had submitted but from your comments I understand it could be confusing and it could be improved.
I wanted the broken piece of glass and its reflection in focus, which I think is there, to show the fragility of the glass. The frame was not so important to me but I understand now it may have given more context.
It’s interesting that some of you have seen a pair of scissors, it wasn’t intended but I am quite happy with that result.
I do struggle to understand the concept of photo sharpness, so I am bit confused by your comments:
Doesn't look very sharp to me...
great image, lovely and sharp
So is the photo sharp or not?
Thanks again for your comments.
