I would like to present my entries to this week’s Weekly Photo Challenge: Focus.
It is of paramount importance for a photographer to decide where to focus before pressing the shutter release button. And when focusing the value of aperture must also be taken into consideration as this determines the depth of field or how deep is the area of focus.
I have divided my sets of pictures into two categories: The first category is pictures with shallow depth of field which results from wide aperture and pictures with greater depth of field resulting from small aperture.
Shallow Depth of Field (Wide Aperture)
Taken with Nikon D80 + Nikon 50mm f/1.8 lens | ISO 400 | 1/250s @f/2
Large aperture (f/2) was chosen to throw the background out of focus – the common technique applied by photographer when shooting portraiture. At this aperture focusing is crucial and must be accurate because of the resulting shallow depth of field. For a portrait shot focusing is always aimed at the eyes.
Taken with Nikon D80 + Nikon 18-135mm lens | ISO 800 | 1/60s @f/5.6
Whether the portrait of a human or a parrot the same technique applies – large aperture to produce shallow dept of field which enables us to throw the background out of focus and we can get sharp image only on the subject.
Taken with Nikon D80 + Nikon 50mm f/1.8 lens | ISO 400 | 1/60 @f/2.8 | Built-in flash was fired
A portrait of my first daughter, Nur Batrishia Khadijah, at night illuminated by fuilt-in flash. The colourful lighting of the fountain in the background at KLCC area was thrown out of focus and formed a nice colourful pattern.
Great Depth of Field (Small Aperture)
Taken with Nikon D7100 + Nikon 16-85mm lens | ISO 400 | 1/160s @f/14
Small aperture (f/14) was chosen when shooting this heritage building in Kuala Lumpur as I wanted the dome and the arch that frames the dome to be both sharp and in focus.
Taken with Nikon D7100 + Nikon 16-85mm lens | ISO 200 | 1/125s @f/11
Again when framing architectural shots I prefer great depth of field so as to render the frame and the subject sharp by opting for smaller aperture, in this case, f/11.
Taken with Nikon D7100 + Nikon 16-85mm lens | ISO 400 | 1/100s @f/18
The Kuala Lumpur modern skyscraper, The Dayabumi Complex, whose architecture was inspired by Islamic motiffs is framed by the arch of the adjacent heritage building. In this shot I also selected small aperture, f/18, to make sure the frame and the subject were both sharp.
Taken with Nikon D80 + Tamron 17-50 f/2.8 fitted with polarizer filter | ISO 100 | 6s @f/20
In this waterfall shot both the rock at the foreground and the rocks and the foliage at the background are rendered sharp as a result of small aperture at f/20.
