Macro Photography

Certainly, we are well acquainted with the term “macro” which refers to expansion of a single instruction for a wider view or perception; now coming to macro photography, it is a close up photography where the photographs of living organisms like insects or birds are magnified and we, the spectators, get an amplified view of them. Going by basic definitions, on a macro picture, the size of the subject on the negative is comparatively greater in terms of angular size or shape. Owing to the capability of macro lens for subject ratios, the ratio of the subject size on the sensor plane to the actual subject size is known as reproduction ratio.

Macro lenses of varied focal lengths find different purposes such as:

  • Continuously variable focal length befitting for technically all macro objects.
  • 45-65 mm employed in product photography where small objects can be approached from a close distance without causing undesirable impact.
  • 90-105 mm for capturing insects, flowers and small commodities from a comfortable distance.
  • 150-200 mm for shooting insects and small organisms where extra working distance is needed.

Technical considerations in macro photography:

  • Depth of field – You require to diminish it while shooting macro photography during focusing on small objects, small aperture is needed as well to produce sharp objects for which you need slow shutter speed, amazing lighting or an extremely high ISO. However, more shots can be taken with varied focusing lengths and then the images can be coerced with virtue of a specialized focus stacking software which brings out the sharpness of each photograph by artificially enhancing the depth of field.
  • Lighting – It is difficult to place a source of light very close to the subject which makes the macro photographs impractical, so it is advisable to use adequate and even lighting which can overcome the idea of certain cameras which focus on subjects so close that they touch the front of the lens.

Considering the fact that macro photography majorly deals in size, here’s enumerating its features:

  • Magnification – Your subject is projected onto your camera’s sensor which is larger than the usual life size.
  • Working distance – This is the distance between your sensor and your subject at the closest possible focus distance of your lens, longer the working distance, the more convenient it is to stay away from your subject.
  • Full frame – It is your aim to create fully magnified photographs although full frames sabotage macro photography, with this kind of photography, the highest pixel density is what determines the maximization of the object’s magnification; hence a full frame camera is way better than a cropped-sensor camera.

Despite the fact as to how significantly size and magnification of objects play a major role in this genre of photography, amateur photographers need to keep certain tips while shooting, them being:

  • Choice of best lens
  • Making a standard zoom focus
  • Adding a dioptre to make a lens focus closer
  • Using apertures to keep the depth of field under control

Power to you!
