This was taken at Richmond park with the Canon 300mm f2.8LIS and 1dmk3, I think it was at f2.8 although the water was a muddy colour I post processed the colour tones towards the blue.
Hi Necip, Do I detect the use of flash in this capture with the double catchlight in the eye?, The whites are also a little blown, That said its a good capture with fine detail and I like the PP work giving a great effect on the water, did you use shadow and highlight in PS?
