Hello Henriette here with this months photochallenge and we will be talking about “camera shake” and “out of focus”.
From an article by Elizabeth Halford
There are may ways an image can be made unsuitable. Camera shake and poor focus are two of them. How does it happen? How can you prevent it? And what if you don’t even have one of those ‘fancy schmancy’ cameras?
This article is about how to prevent them from happening.
{Camera Shake}
Camera shake and the resulting motion blur are a result of the camera moving during the time of exposure. Which means that there is movement while the shutter is open and the sensor is gathering information. For particularly long exposures (like evening landscapes or trying to capture a waterfall in soft, beautiful motion), a tripod will be necessary. But even the movement caused by putting your finger on the shutter button can cause blur so you can use a remote control or set the self timer and take your hands off.
If you use a point-and-shoot, camera shake and blur could be a problem if you’re not operating in the appropriate mode. For instance, trying to capture running children in portrait mode will probably result in motion blur. Try sports mode.
For the DSLR users, the heavier the camera, the more stable it will be and less likely to be moving about due to hand tremor. Research proper camera holding and stance for maximum stability.
Some lenses have IS (image stabilisation) options which help to reduce camera shake (and battery life!)
Camera shake becomes less and less a problem the faster your shutter speed and the more light is available. If you’re in low light, opening your aperture to let in more light will allow you to quicken your shutter speed, but then you might have to battle poor focussing.
{Out of Focus}
My pet peeve is improper focus. I’m sure the majority of photographers operate in auto focus mode, unless they’re photographing still life. This means that we allow the camera to focus for us and it does it in a variety of ways.
If you use a point-and-shoot, the solution is pretty simple. You hold down the shutter button halfway until focus is achieved and then push it the rest of the way down. The only reason you’d be likely to end up with poor focus is, as I said before, you’re shooting in an improper mode. For example, you’re shooting a landscape in macro mode.
For us DSLR users, focus becomes another monster all together. Consult your camera’s manual and familiarise yourself with the focus modes and the focus areas because both of these factors result in proper focusing.
Ok and the challenge this week is: show one of your photo’s go wrong by camera shake or out of focus and maybe the reason why that happened!
Here is my not so sharp picture, in this case it was camera shake. My youngest wouldn’t stand still for a picture so I just took a snap very quickly and it shows
!

Please read the posting rules too, especially about posting in the right gallery, thank you!!
- Upload your photo (and LO if you have one) to the appropriate gallery, then please link it back to the challenge in the forum
- Just one entry per person will be eligible for a point, one extra point can be earned for doing a LO with the picture and if you win the challenge you also gain one extra point
- The pictures must be especially made for this months challenge
- No double dipping with other challenges please
And here are the examples on how not to, from:

Here is why this happened: I have to slow down my shutter speed ALOT to get enough light, to take pictures in my house without a flash. So if i move even a little bit while taking a picture i get blur. So that along with the fact that she wouldn’t stay still resulted in this picture:

even in blur her puppy looks cute!
And another one from:
hoo-rah
I think this blurry shot is the result of both a camera shake and improper focus. First, my daughter was in a fit of giggles when I was trying to take this, so she wouldn’t stop moving (happens a lot). Second, the auto focus and auto flash on my point and click had been adjusted (anonymously), and there was not enough natural light in the shot to get proper focus….hence, the blur.

And doesn’t her daughter still looks very sweet in that picture?
