Photography: Image composition and image data meta-analysis for quickshots (mobile subjects).

“A good picture is not only about the moment you spent clicking but it’s about a moment that clicked you and the one which you wish to keep in the years to come”. So it is evident that preparing for that special moment is highly essential. there is a common proverb in photography  which says ‘victory loves preparation’.

Many readers many times ask me ‘how do we prepare for a moment that is unexpected?’ well the answer to that is simple be alert and expect the unexpected. For a good preparation of shot a few things are highly vital i.e. a good shutter speed which gives you a buffer of even if your object of interest is in motion. An ISO setting about 100-400 is good for most days to evening shots. And most importantly a good aperture (F value) for best light input in scenario is highly helpful. The trick with apertures is that lower the number F 3 or F 2.5 higher is the aperture. A well planned shot can have lower aperture values like F 10, 11, or to the count of f 22, 23. But for a quick shot it is always preferable to have higher aperture so that enough light reaches the sensor. For moving subjects like birds, or animals it is always good to have a high shutter speed and a good aperture as this avoids camera shake and give you the shot you need. Many times it is true that with this the shot can get a bit over exposed but it is something which can be rectified in the studio but a highly underexposed shaken shot cannot be resurrected.

Illustration:



This is an image of a German Adder shot from approximately 40 cm from the snake. In such a situation it is highly important to quickly evaluate how your picture would look when you have taken it. It would be a folly to have a good picture but miss-focused. The snake moves fast and it highly important to keep the eyes and nose in focus to create a composed image.

The best way to compose animal snaps is to make sure you get the eyes and nose in focus.  This is not very difficult but sometimes is not evident when you take images of mobile subjects. Many times in the excitement of the shot you are tempted to take multiple exposures but miss little points like the focus, aperture, and shutter and realize after the excitement that the shot has been spoilt with silly mistakes.

So in summary as a general rule to have good shots you need a decent shutter speed about 1/125- 1/ 1000 seconds and you need a good aperture value of about f-2.5 – f 7.0. There is no doubt a lot of trial and error factor to it, and practising is highly essential. It is important to feel your machine as get one with it. This only happens with practise. So keep practising.

In the next article I shall be concentrating about how to take planned shots of landscapes and seascapes, clouds and sunsets.

Kind Regards,
