Since the advent of digital photography, there have been various improvements in ways photographs are taken. In spite of the vast enhancements, there are professional photographers who are still hesitant on embracing the digital photography completely. This is mainly because of the various myths that surround it. Here are top 5 myths and how to counter them.

Myth -1: Megapixel thing

There are various myths related to the pixels and their influence on the image production. Here are a few:

  • Increased pixels give sharp pictures – Increasing the pixels does not guarantee increased sharpness as for a sharp picture, you need to control several factors of which enhancing the sensor resolution plays a small part.
  • More pixels for bigger prints – Digital cameras have only 50% effect on the resolution and it is more effectively done by using a printer, which has over 500 ppi. Printing large pictures with high megapixel does not therefore make a big difference.
  • High megapixels are needed as lenses are not sufficient – The real fact is that even mediocre lenses of both zoom and fixed focal length of 35 mm can give a good resolution as a 36 megapixel does.

Myth 2: Full Frame Cameras Give Better Lens Flexibility and Sharpness

The effect received with a full frame camera can be easily achieved and at an affordable way with Micro Four Thirds type of cameras with any lens type, whereas in full frame version, there are certain lenses that do not work well. Sharpness of the picture is controlled by the pixel size, depth, the lens, distance of the subject and skill of the photographer, and certainly not by the full frame cameras.

Myth 3: Autofocus Measures the Distance from the Subject

Most of the modern autofocus systems function in a passive way and use echo for focusing, which gauges the light that enters into the camera via the lens. Phase detectors are used to measure the distance and how in focus the subject is, and adjusts the lens till the right contrast is reached. The distance is therefore not needed and is not measured by the autofocus.

Myth 4: Image is Distorted with Wide Angle Lens

When you speak of distortion though people generally refer it to lens distortion, there is also another type called as perspective distortion which is more significant. The lens distortion can occur in different degrees based on the wide angle design of lens. For instance, the fish eye lenses give a wider angle of the view with severe distortion and there are the wide angle prime lenses that give minimal distortion. So it is not the wide angle that causes distortion.

Myth 5: Calibrating the Hardware is not Necessary

This is a terrible mistake that will end up with the image you see in the camera not matching the one you print. Calibration is actually an easy process, which ensures that the colour matches exactly. Without proper calibration, devices can alter the alignment in them. Regular calibration will effectively increase the precision factor.

The myths usually are generated because of lack of sufficient knowledge regarding the way a picture is captured. Basic photography skills with regular practice help you identify the right techniques and methods that give you results unerringly.
