Depth of field examples

Whilst in North Wales, I visited a Zoo and wanted to take images in order for me to demonstrate my understanding of depth of field.

The below images show 2 pics of the same penguins.

I stayed away from the temptation of using auto focus as I believe that my confidence and skills have developed so much that I nearly always use manual now to get the image I crave for.

Depth of field is the amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph. A preferred selection Depth of field in a focused subject in an image can be quite subjective. Remember this, adequate selection of DOF for one situation, application may be unacceptable for another photographer. It is all a matter of personal preference when trying to determine the appropriate use of DOF to enhance an effect in a photograph.

For health and safety reasons, I was very careful of what and who was around me whilst at the zoo.

The depth of field is demonstrated in both images mainly using the focus ring (pictured above) and the correctly balanced funtions.

IMAGE 1
I used a very shallow depth of field for this image and this clearly shows in my image as the penguin nearest to my lense is clearly in focus whilst the penguin behind is out of focus. Images taken with a shallow depth will place more emphasis on objects closest to the camera lens. As follows........

IMAGE 2

I used a DEEPER depth of field on the focus ring hence the subject further away from the lens is in clear focus whilst objects nearer the lens are out of focus as my image clearly shows......

  1. Hi
    I can see how you are improving you written documentation of what you are doing, this small experiment will tick off, 1.1,1.3,1.4,1.6,1.7,and 1.8 but again ONLY with a little more supportive written work, same as the wales shoot.

  2. Hi
    Also will you do me a favour, I want you to label all your posts with a criteria number in the bottom right corner of a new post there is a label space, put the criteria number there, then get a new gadget and add the label gadget to your layout, this will then list all your criteria and become easier to follow for you and me when marking.
