Shutter speed also changes the way moving objects appear in certain photographs. Using a very short shutter speed is often used to freeze fast-paced subjects (or objects) in the frame. This could be used for example, in sporting events or capturing running water. A longer shutter speed can be used to take images of moving objects that will blur in the photogrpah. This is done deliberatley to create this artistic effect on the image.
Due to this, short exposure times are commonly called 'fast' (since they take images of quick-paced objects), and long exposure times called 'slow' (as they are usually usded to take shots of slow objects).
Problems:
Since the objects are moving, it is harder to take a well composed image; more problrems will arise than if you were just taking an image of a stationary object.
It is important to check images after taking them incase any of these issues arise. It is far easier to retake the images on the spot rather than hvaing to do another shoot. Knowing these points is essential so you can spot any mistakes and improve photographs straight away.
Focal blur
This can occur at any time, especially when changing pose or position. You could assume the camera is still focused, this is often not the case. It is extremely important to keep images in focus or they will be ruined.
When using manual focus it is very important to check to see if the image is properly positioned. If the photograph is out of focus, it is ruined and can't be undone.
If using manual focus is too difficult, use automatic focus mode that will do this for you. Making sure all images are in focus is a top priority.
Underexposure:
One issue could be underexposure in the image. This is when not enough light has gotten into the lens and the image is too dark and shadowy to be of any use. This could happen when using a very short shutter speed; there was not enough time for an adequate amount of light to get throught to properly take the image. Although the speed had to be shorter to correctly capture the movement in the image, a balance must be met to ensure this problem doesn't happen.
To solve this problem you could retake the shot using a different shutter speed to allow more light to filter into the lens. Using a slower shutter speed could help this issue. It is important to try different speeds to find the correct balance between exposure and capturing the movement desired in the image.
Taking the photograph at a different time of the day or in better lighting conditions would also sort this problem out. Changing the setting of where the image is took, to a place with better lighting is helpful if you want to keep the same shutter speed.
Poor framing:
This is when things are cut off in the image or the intended subjects are too far away. If hands, heads or other body parts are missing, all contributes to a poor image. Also if the subject is too far away in the image, the correct shot distance hasn't been used.
In order to deal with this problem it is essential you check your images as soon as you have took them. This allows you to review them straight away and check if anything is wrong with them.
Making sure to choose the correct distance for the shot is important; you don't want to be too close or too far away. This could mean getting closer or further away from the subject. Zoom only works so well, it may require more planning on the photographers part to make sure the model is in frame correctly.
Taking your time to take the shots is also helpful. If your subject is moving you could time everything correctly to take the correct photographs; instead of your model moving randomly. This could save a lot of effort later; having to retake the photographs for every shot.
Using continuous shoot mode will take lots of images with one click of the camera button. This increases the likelihood of capturing the shot you wanted. If the person is moving, it makes it more difficult to get the photograph of the pose you want. By using continuous shoot mode you can take lots of images in order for you to find the right one.
However this does make the process more time consuming as you will have to go through all your images to find the right one. Though getting the perfect photograph is surely worth the extra hassle.
Using a tripod to keep the camera still could also be effective. Missing things from the image could be human error, if the camera wasn't steady enough when taking the image. Using a tripod would solve this issue and keep the camera stationed in one place.
