Lens Perspective

Monday 14th October 2013

There are many different types of lenses, which affect the way a subject is portrayed. Varying lens types affect the depth of an image, fooling the eye by either ‘condensing’ or ‘expanding’ the distance between objects. Also the aperture used combined with different lens lengths creates a great or small depth of field. For example:

(My lenses)
70 – 300mm – an image is almost ‘flattened’ – the sense of distance is distorted and shortened.
24 – 105mm – the image appears very ‘deep’ or ‘long’ – there is a great distance created between objects.

We experimented with these in our lesson as a task. We had to try out each of the focal lengths (300mm, 50mm and 28mm) using the largest aperture then the smallest aperture and seeing how it affected the aesthetics of each image.

Here are my results from the lesson.

300mm  Shutter speed 1/60. f5.6, ISO 2000

300mm
Shutter speed 1/60. f5.6, ISO 2000

70mm 1/60. f4. ISO 2000

70mm
1/60. f4. ISO 2000

24mm 1/60. f4. ISO 1600

24mm
1/60. f4. ISO 1600

You can see the difference! Wow. I personally prefer the affect and distortion of the third image, I like the depth in it!

The thing when shooting at 300mm is because it’s such a long lens and when you zoom in with it, it takes the aperture smaller so less light can get in, and you have to use your shutter speed to get the right exposure, but reducing it’s pace can make camera shake inevitable. I like how the third image is much more crisp too – something that’s more difficult to achieve when using the 300mm lens.

I wanted to shoot some more trying out this method as it didn’t get chance to have a proper go (in the lesson) and see the affect in my chosen genre. I love portraiture, so I tried a few out on my brother! Here are my results:

24mm 1/60. f4. ISO 200

24mm
1/60 sec. f4. ISO 200

24mm 1/8 sec. f8. ISO 800

24mm
1/8 sec. f22. ISO 800

70mm 1/60 sec. f4. ISO 200

70mm
1/60 sec. f4. ISO 200

70mm 1/8 sec. f22. ISO 800

70mm
1/8 sec. f22. ISO 800

300mm 1/60 sec. f5.6. ISO 800

300mm
1/60 sec. f5.6. ISO 800

300mm 1/8 sec. f22. ISO 800

300mm
1/8 sec. f22. ISO 800

24mm 1/60 sec. f4. ISO 400

24mm
1/60 sec. f4. ISO 400

105mm 1/60 sec. f4. ISO 400

105mm
1/60 sec. f4. ISO 400

67mm 1/60 sec. f4. ISO 400

67mm
1/60 sec. f4. ISO 400

24mm 1/60 sec. f4. ISO 400

24mm
1/60 sec. f4. ISO 400

It’s amazing how just changing the focal length (without even changing any of the other settings) can make such a huge difference in the way someone is portrayed! I like the effect the 24mm gives, as it creates such depth to an image, however I would say the 70mm and 300mm are more flattering for portraits, and create a better and more realistic portrayal of how someone looks to the natural eye. I want to practice this more and more, even when just taking photos in my spare time, as it gives more opportunity as a photographer to experiment and get the exact desired effect.
