Why sharpness is lacking at some places?

[sonalidalal]

some part of the picture has good clarity and sharpness some part does not have it. Can you please explain why this happens? I have tried to correct it with Picasa (Cuurently i only have Picasa) but to no effect.

i think it would be easier if the EXIF data is included

Agreed. Most likely your aperture was open too wide, giving it a more shallow DOF.

Sorry! I forgot to give the details.

Camera: Canon EOS 1000D
Shutter Speed:1/30s
Aperture :f/5.6
ISO:200
Focal Length:55.0 mm

It's simply a matter of depth of field...a term used by photographers describing how much, or how little of the image is in sharp focus. It works no different than your own eye...hold a finger up in front of your eye and focus on it...everything beyond the finger is out of focus...the camera lens works the same way. As long as your main subject is in sharp focus all the rest is secondary. You can control how much, or how little of that by learning to control your aperture. A small aperture (bigger F number)gives you more of the image in focus. Conversely, a large aperture (smaller F number) gives you shallower focus, aka: Depth of Field.

At aperture f/5.6, it would be impossible to get all in focus.. you'll need "at least" f/8.. then again slower shutter speeds might cause blurr due to wind movement/ hand shake. I believe this was taken at a low light situation. Shooting at a different time of day when it is brighter/ when there is more light will solve this..

Your answers really helped.

lol what am i thinkin?! sorry i'm on the wrong page..mah bad i think lens does its best focusing when set to 2 stops smaller than its widest aperture.it will produce the sharpest images not at f/5.6.

Thanks . Can you explain to me something about metering. i am not very sure about the concept.

I believe your camera will have three types of metering available:
1) Matrix Metering - evaluates all the light in the entire image, and makes an exposure judgment based on that (good for landscapes / cityscapes and most shooting opportunities)
2) Center Weighted - looks at the center area of your image only, and makes an exposure judgment based on that (good for portraits and where you want the exposure on the subject to be best)
3) Spot Metering - takes a small area of the image that you select, and makes an exposure judgment based on that. The size of that metering spot varies from camera model to camera model. The more expensive DSLR's have a small spot, while it's usually a larger spot in less expensive camera models. Using this will allow you to decide on whether you want to meter off of the highlights or the shadows giving you a more precise reading.

One last comment, the camera's choice of exposure can always be overridden in the creative modes on your camera's dial, and/or by using your EV up or down. Read your manual...it's all there for you

The exposure used on your image above will not have any bearing whatsoever on what's in focus, or not
