How do I get a sharp picture with my Canon EOS 50D?
Posted by admin | Under Canon EOS 50D Monday Mar 29, 2010Every time I take a pic with the full auto option, my picture becomes slightly unsharp. I do not want to adjust the shutter speed for every single picture. How do I get a very sharp picture every time I take a picture? (and yes….I do keep my hand still 
)
Thanks
One question: why did you get a dSLR if you intend on using it in full-automatic mode ?
You really do need to learn to select focus points and shutter speed. Selecting one shutter speed for all instances does NOT work. For example 1/90 might be OK for portraits, but it will not work if you are shooting sports. Then you will need at least 1/250th, but 1/1000th is better. Next, you will need to understand ISO and how to set it according to the environment in which you are shooting while also considering how this will impact the noise and grain of your pictures. What you really need is to understand the concept of "exposure" as a balance between ISO, shutter speed and aperture.
You want better pics ? instead of asking for a one-size-fits-all advice on Y!A, register for a photo course. If you don’t want to do this, then at least attend a one-day workshop at your local photo store, many offer them for free.
High powered flash will do the trick you may need a studio strobe if you plan on shooting in daylight though. Also make sure you don’t miss focus.

It’s hard to answer your question without referring to settings. Generally, you get much sharper results from a given lens if you shoot towards the middle of the aperture range. Say, f/8. If shake isn’t the issue, that’s the next thing to try.

Its all but impossible to answer this intelligently without knowing the conditions you’re shooting in.
Please revise your question with additional information. Then I’ll revise my answer.

There are a few things that result in less than perfectly sharp images.
Firstly, and most obviously, focus. Check that your camera is focusing automatically. You need to select this separately, on the lens body, from selecting the full auto on the camera mode selection. If you are taking pictures of something with a high contrast background or foreground, cameras often focus on these instead of your intended subject. Try limiting the autofocus point to just the centre to make this more accurate.
Secondly, shutter speed. If your shutter speed is less than the lens focal length (ie for an 85mm zoom, you need to use 1/90th which is written as ‘90′ in your camera) then tiny movements in your hands, smaller than you have any control over (like your breathing and your pulse!) will cause the lens to move around and cause things to blur. If you have the kit lens and don’t want to have to set this for every shot, 1/90 will cover it for the whole zoom range.
Another thing with shutter speed is stopping the movement in your subject. The shutter speed you require varies depending on how fast the subject is moving. If you’re using the previously mentioned 1/90, that’ll be fine for people, but if trees are moving in the wind you may require a bit higher, and even more if you’re trying to capture something like a moving car.
If this leaves your images too dark, you’ll have to use a flash to illuminate the scene.

Hey,
I have an article on my blog about not getting blurred pictures with 5 tips. You can read it here – http://the-digital-photographer.blogspot.com/2009/11/camera-shake-get-rid-of-it-in-5-steps.html
The most common reason for blurred photos is of course, the shutter speed. If you have lens at 50mm, your minimum shutter speed should be 1/60.
Tripods, monopods, timers etc are listed on my site.

Me, my blog.
You may want to look at the shutter priority section of your manual (called Tv or Time Value). This mode lets you set the shutter speed (and you set the ISO) and the camera will pick the appropriate aperture to give you the correct exposure.
Unless you are under some quickly changing light conditions you would not need to change settings with every picture.

proberbly your iso settings are too low for the light conditions that you are using, resulting in camera shake. if your iso settings are to high you will get grain ( noise as they call it these days ).
if you use a low iso setting then use a tripod.
if using a tripod then use a slow shutter spead, and a smaller aperture ie f11-f16.
err i forgot
u cant do all that on auto, so switch to manual settings and experiment until you are comfortable and get a feel for what you are doing
