Digital photography is one of the most popular forms of photography in the world, and now that many advancements have been made in photographic technology that more and more people are engaging themselves in this amazing craft.Just like any other form of photography, it is also not unfamiliar with misconceptions and myths, and these are related things about which we are going to talk in this article. If a photographer acquaints himself/herself with these myths, then he/she can produce higher quality work.
Here are 5 Don’ts in digital photography which everyone must keep in mind:
1. ISO does not change the sensor sensitivity
Contrary to film, digital sensors possess only a single sensitivity. Changing the ISO in a digital camera will not increase the sensitivity of the sensor—it really does not allow the camera to capture more photons. Instead what happens is the amplification of a weak signal and the noise accompanying it.
The experience is like increasing the volume on a low-quality audio—it is not good, but you can hear it anyway.
One tip to remember: High ISO results in a noisier image, and latest technologies have emerged that allow photographers more options to maintain dynamic range (you’d know what it means!).
2. There is never a perfect exposure for a particular photo
Remember that there is no such thing; instead, there exists a moderate signal-to-noise ratio (abbreviated as SNR).
The perfect exposure is largely subjective, but from the viewpoint of electronics, you should get the best SNR available since that will offer you the most latitude for the purpose of post-processing the image.
3. Larger pixels do not necessarily yield better picture quality
Under the low light condition, larger pixels generally possess higher SNR to allow greater capture of light; however, these pixels trade resolution, and what turns out is that during bright conditions, smaller pixels possess better resolving power and a higher SNR.
Camera manufacturers choose pixel size as per particular applications, and there are always compromises to be made.
4. Higher bit-depth does not mean better quality pictures
Bit-depth concerns the analog-to-digital converter’s resolution in your camera. If the bit-depth is higher, then more information from a pixel can be curtailed into smaller units causing smoother tone transitions. But, the higher we go, more problems may arise.
There is a diminishing returns point caused by noise and eventually, quality gets affected. Thus, wanting higher bit-depth is akin to desiring more megapixels.
If at all you require the ultimate image quality, then remember that there is an interplay of several variables.
5. Do not forget to clean the image sensor
This one tip is a little different from the others mentioned but is as important as them.
There is this common misconception that only the manufacturer of the camera should clean the sensor because you may accidentally cause damage to the camera. This is stupid and sheer waste of money.
The image sensor contains a glass cover which is hard enough to prevent scratches. Thus, the tip is to do it yourself and do it on a regular basis.
