Nice image. I would have liked a bit more space on top. You could have tried using a lower ISO (if possible).

Nice composition. Liked the low angle and the patterns in the water. The eye contact is fine. Look forward to more.

Nice image. The low angle and the broken reflections look great.
Look forward to more.

I like the low angle. Where was this photographed? A higher shutter speed is better if you are photographing from a boat. Which lens did you use? Nikon 500mm? Look forward to more.

Hi Sabyasachi..

Thanks
I used Sigma 150-500mm lens. It was photographed in Ranganathittu Bird Sanctuary.

Hi Sadananda,
Most of the lenses are sharp at one stop higher than the widest lens opening. I have never tested the Nikon version of that lens. However, I have been told that the lens is sharper at f8 than at f6.3. You may conduct tests yourself to validate that.

Cheers,

Hi Sabyasachi,

Thanks a lot for this input. I had read this in some reviews but never practiced it. I shall try ur advise.
Some times even f6.3 itself allows a very slow shutter speed. I wonder how would f8 be. I think I have to increase the ISO to get higher shutter speeds and sharp image.

Thanks
Sadanand.
