Focal Length Experimentation - Techniques Work Diary
Overall, I liked both my series for this shoot, as well as the extra experimentations which I carried out for the 70mm focal length. I had my camera on ISO 100, the shutter speed ranging between 1/60 and 1/160 and the f/stop at around 9. I like the outcomes and feel they worked well to show differing focal lengths. To carry out this exercise, I used a tripod to ensure the framing of my images remained the same.
For this shoot, as I only produced two series, I did not have a least favourite as they were both successful. However, I do have a favourite series which are shown below.
I like the way that this series allows you to clearly see how the images change in respect to distortion, field of view and depth of field with varying focal length. As the focal length increases, the distortion becomes less noticeable and is more obvious at the 18mm focal length which uses wide angle. Also, with a shorter focal length, there is a wider depth of field as the majority of the image is in focus in comparison to the 70mm focal length when only the person is in focus and the background is blurred. Also, the field of view becomes much narrower as the focal length increases.
Progression
If I were to try to carry out this investigation again, I would look into extending my study and using a long telephoto lens to try a wider range of focal lengths including 300mm. However, I still think that the smaller range on my camera was successful at helping me understand and develop my technique involving differing focal lengths. I would also try to photograph a wider range of subjects and not just focus on portraits.
From carrying out a shoot based on this technique, I feel as though it is something I would naturally use in my personal investigation. However, I would not create a series like I have done in this shoot. Nevertheless, I feel the session and shoot on this technique has been useful in aiding my understanding as to how a change in focal length can change the distortion, depth of field and field of view of an image. This would therefore be the aspect of this technique which I would apply to my shoots for my personal investigation.

Chloe, again a well constructed experiment you will however need to add a label underneath each picture to denote the focal length that you actually used.. this will help the view understand your work more easily.
