Boats

Photographed it after Sunset on banks of Nethravathi River. Placed my camera on a tripod, framed the scene, set the auto focus to wide and aperture to the smallest f/8 .
Clicked with self timer of 2 sec to negate any camera shake, when pressing the shutter button.
A image or sky reflected on water makes an interesting monochromatic image with tonal variations. Such reflections also add symmetry to an image.

Reflectons in a Well

At Kudupu in the outskirts of Mangalore is this well, nothing special about it, except that I found the water so clear that I could see more that 20 ft under. The trees reflecting on the water and on the left the palm of a coconut tree fallen and lying gracefully underneath the water all adds some kind of serenity to the well.
Photographed with the smallest aperture f/8 that i could to get in all the details ;1.2sec shutter speed.

Summer Day Reflection

As a thumb rule, when photographing reflections, use the smallest aperture possible (the largest f value); unless you want to capture a blurred reflection. In this photograph, I did want to frame in the entire tree crown, but the water body imposed constrains in doing that. Here I have used a f/8 aperture the smallest possible with my Sony-H7. Since the image is a reflection and the smallest aperture was used;a slower shutter speed had to be used, and to prevent camera shake, I did use a tripod. Now Since the water was still, the image turned out to be sharp, in case of a moving water body, then the above settings may not give the best results. In that case either use a higher ISO or a little bigger aperture.
