#1 - probably would have looked better without the CP so you didn't get the darker middle in the sky. Othwerise my third fave of this bunch
#2 - clone out the bird & straighten the horizon (NOW!
). I found the shadows from the bridge a little distracting on this - I'm guessing this was shot late in the day - again I think this would have been better without the CP
#3 - My second fave. I like the composition and the touch of vignetting around the opera house works well. CP made a difference to this one IMHO
#4 - falls 1/2 way between #5 and #6 and fails for me - sorry
#5 - I like the composition on this one, but think the shot would be stronger with a little less of the dark foreground to draw me more to the boats
#6 - my favourite of the bunch. The reflections are superb and the colours nicely muted. Maybe try cropping out the buoy on the LHS.
Thanks for sharing these. Have fun with the CP (BTW I have one - a 77mm and use it on my 12-24 and, occasionally, on my 70-200 VR - some day I'll get one for my 24-120)
Where are the shots of the whales!
