While a soft blur might give a photograph a particular “feel” or artistic touch, it might also ruin the entire image. This is something that is not always avoidable, but there are some tips and tricks to help a photographer obtain the clearest images available.
The first thing to consider is the ISO. Before the advent of digital photography, the ISO referred to the film’s “speed”. Generally this implied its sensitivity to light, which is also how digital photographers look at ISO as well. ISO is a setting that is done through a number, usually ranging from 100 to 3200 or more.
As the ISO setting is increased the camera sensor becomes more sensitive to the light striking it. The one instant effect you will get from changing ISO from a lower number to a higher number is that you may not need to use a flash for a picture; you will also however introduce something known as “noise”. This is a graininess that is the result of digital technology and is entirely impossible to avoid with high ISO settings.
So, an indoor scene with only a little ambient light might be able to be captured by a high ISO and slow shutter speed. Naturally, the slower shutter speed will mean that hand-holding the camera may be out of the question because it could allow the image to be blurred, but so too can the high ISO. This is because the higher ISO creates graininess in the image.
All of this translates to the simple fact that a photographer hoping to increase the clarity of their photographs should aim for the lowest ISO possible.
The next thing to consider when the sharpness of an image is vitally important is the type of lens being used. Many modern digital cameras are marketed as containing powerful zoom lenses, but these may not be the result of the actual “optics” of the lens. Instead, these might be digital zoom lenses that use the tiny computer within the camera to enlarge an area of the scene to bring it in close.
This is not a “true” zoom of the scene and is usually difficult to capture without a great deal of blur. While it might allow a photographer to capture an image of relatively decent quality, they will discover that any work in a photo-editing program will end up looking awful. This is because the actual image on the memory card is not clear or sharp in any way at all.
Is there any way of avoiding this and still getting a zoom? The only way of recording a clear, original, and true image is to use the optical zoom on board the camera, or to purchase one that can be attached to an existing camera body.
