Forrest,

Like the composition of this one, the while object with dark background, waterdrops, reflection make this photo be excellent.

Only wish to see more its bill (with fish?!?). I would suggest to make it slightly darker for the whole picture. And looks a bit over sharpened but it may be due to the problem of my old model of EIZO LCD monitor.

Best
Daniel

Hi Danial,

Long time no see. Thank you for your comment.

I also wish to see more its bill with the fish!
It looks ok at my EIZO LCD monitor. Maybe the oversharpening you saw is the slight blur of the image.
I got 10 shots of it but 9 of them are out of focus or blurred. Only this photo is the least blurred one.

After taking this series of photos, I sent all my gear to Canon for checking. In this morning, I was told that my IDII is having "back focus" prolbem. Oh my God, I was using a "back focus" camera in the past one year.... :'( :-[ :'(

Forrest :-X

Forrest, what does it mean a 'back focus problem'? Is it focussing behind the critical point?

thanks

Andrew

Hi Andrew,

Yes!
