Wide Apertures

Shooting people with wide apertures is fun. Lots of fun. The images that you get are often fantastic (the good ones that is). The only problem is just that – “getting good ones”.

Wide apertures gives excellent subject isolation – which is good – this is required so as to direct the viewer to what “you” see. This is the reason that the wider the aperture a lens has, the more expensive it is.

The problem with wide apertures is Depth Of Focus (DOF). The wider the aperture, the shallower the DOF.  The shallow DOF also means – focusing issues.

Some tips based on experience:

  • Shoot with easy wide apertures (f4 through f5.6)  to get away with most DOF and focus issues (This does not apply to landscapes, Only for people – single or small groups)
  • Best apertures to shoot portraits is the best highest aperture your lens can provide – this is usually one stop to two stops from the widest ones.
  • Best lenses to use for headshots are in the range of 75mm – 135mm (35mm equavalents) .
  • Best lenses to use for full shots are in the range of 35mm-70mm (35mm equavalents)
  • Best lenses for wonderful subject isolation are the ones that offer apertures in the range of f1.8 or wider
  • Examples of holy grail lenses are the Canon 85mm f1.2 and Nikon 85mm f1.4. The 28-70mm f2.8 and 70-200mm f2.8 zooms are usually regarded highly as well (and are the most favoured by Wedding photographers).
  • For single portraits – key is to focus on eyes. Use AF-Lock button if your camera has it or hold shutter button half depressed and reframe the subject.
  • Shoot multiple images each time you hit the shutter button. At wide apertures, even the slighest movement will blur the image.
