Techniques: Focal Length: Work Diary Evaluation -

Focal Length - 

Equipment Used: 
Canon EOS 450D, standard lens, tripod. 

Settings: 
1/100, F/6.3, ISO 100

Lighting: 
Natural outdoor lighting.

Theory: 
N/A
Favourite Series:





The above images are my favourite series in the experimentation of focal length for a variety of reasons. Firstly, the composition of the subject is well placed within the landscape so that the difference in focal length can easily be seen. Additionally, the lighting was slightly better for this series as I configured the settings for this series rather than the second; due to the lighting the images appear crisper.

Least Favourite Series:







This series is the lesser in comparison to the first. The subject kept perfectly still for this shoot which is one good feature although some of the qualities that make it my least favourite of the two shoots is that the lighting could have been changed for example through an increase in the shutter speed to around 1/125 and also by increasing the f/stop which would have meant that the images would appear crisper as they are in the above series.


Evaluation and Development - 

This technique exploration has been successful mostly due to its simplicity and purpose which intends to teach the control of a camera. It also encourages photographers to explore various focal lengths when completing a photoshoot. This series is successful due to its natural lighting, use of a tripod and interesting background. 

I may be using this technique in the future to ensure the framing of my photographs well fit the subject; whether that incorporates a surreal landscape or fashion item I will need to consider this technique.

Focal Length - 

Definitions: 
  • Focal Length: The distance between the centre of a lens and its subject. 
  • Field of View (FOV): What can be seen. (Determined by angle of view from the lens to the scene (Horizontally and or vertically). 
  • Wide Angle: A lens with a short focal length than standard and this provides a wide field of view.  
  • Standard Lens: A lens with a focal length of 50mm is considered normal; they work without reducing or magnifying the images; reflect the way we see with the naked eye (Angle of 46 degrees). 
  • Prime Lens: Fixed focal length which does not change (Higher quality).
  • Zoom Lens: Allows the user to alter the focal length (More versatile).
  • Telephoto Lens: A lens with a larger focal length than a standard; provides a narrow field of view with a magnified image.
