Above & Below Shots- using different angles and perspectives can create varied meanings for the audience. In my example the image taken from below, gives the illusion that the bottle is extra large and overpowering, whereas the image of the bottle from above makes the image look small and distorted.
Above Shot  Shutter Speed is the amount of time that the shutter is open, letting in light to the sensor. It can affect how movement is captured, whether it looks fluid or as if time has stopped. In my first example I used a fast shutter speed of 1/1,000, which caught the football perfectly focussed in mid air.  Shallow Depth of Field I captured a shallow depth of field in the first image by setting a very wide aperture of f1.8. This caused the subject to remain in sharp focus with the background out of focus, attracting the viewers’ eye to the subject.  | Below Shot   In the second example of shutter speed I used 1/13, which caused a lot of motion blur. While trying to capture the ball without the whole image being blurred I came to realise that the task would be completed much more successfully using a tripod.  Greater Depth of Field The second image shows the difference by using a small aperture of f22, which created a greater depth of field. It should be noted that because the aperture changes how much light enters the lens it influences the shutter speed. For example when using a large aperture of f1.8, the shutter speed was fast at 1/250, whilst the f22 example had an exposure time of 1/60. |
Breaking the Edge is a technique that can be used to engage the viewer into paying more attention to an image by its abstract nature and sometimes striking composition. Normally the subject is very tightly cropped, breaking the edge of the photo. In my photo I have chosen to concentrate on a guitar as my subject and I have tried to use a low angle as well as moving in close up to create a breaking the edge image, causing the viewer to pose questions about the image.  |  Focus Through is when there are two or more subjects in an image but the focus is on the subject furthest away, causing the closest subject to be out of focus. This effect is created by using a shallow depth of field such as f2.8, which attracts the viewer to the object in full focus. In my example I took the image from a lower angle, to be in line with the subject and looked through some flowers, as you can see the flowers are out of focus and the man furthest away is in focus. I created this image by using a shallow depth of field with an f5 aperture. |
White Balance these example photos show the difference using the correct white balance can make, comparing 2 versions of the same photo taken with different white balances. White balance affects the way the camera captures colour. One photo shows the correct white balance, resulting in accurate and true to life colours, whilst the other photo appears to be off-colour with a cold blue hue. Using the auto white balance setting is usually acceptable with modern DSLRs, and shooting in RAW allows the white balance to be adjusted in post-production.
Bad White Balance  Long Exposure I took this photo using a long exposure to capture the light trails of the moving vehicles. I had to use a tripod because the exposure was so long at 2.5 seconds. A low ISO was also used to ensure image quality with minimal noise. Long exposures can create interesting effects, however they are often impractical because they require the use of a tripod or similar.  | Bad White Balance  |
