There is a common belief that a high-resolution camera will produce a better image quality.
But, the matter of fact is the Megapixel rating which is also a sellable term for many marketers actually means the number of pixels a camera can capture per frame, which is, not at all relevant to how the image quality will be of that image captured.
In fact, many experts also believe high megapixels rating on a small sized camera/pocket-sized smartphones can often be a bad indication.
The reason as I would say is, as the technology brands are pouring down millions of excessive pixel into a small device to drive customer’s attention, the pictures tend to get noisy or grains come out at low lit condition.
If you ask me, Why? This is what I will answer:
If so much information is captured into a small space(sensor) then what else can be expected?
There are many other factors that determine image quality of the camera you are willing to buy.
1. Image Sensor:
Image Sensor, the high light-sensitive element is found inside a camera, it is basically the film(which we earlier used to use in analogue cameras) of the modern day digital photo guns.
This extremely high light sensitive component is responsible for registering the image you have captured.
Needless to say, the quality of a picture highly depends on it.
More specifically, the area cross section or how bigger the sensor is, better the picture becomes.
Broadly speaking, there are 5 main types of image sensors: (arrangement with resp. to size from larger to smaller)
- Full-Frame sensors
- APS-C sensors
- Micro 4/3rd sensors
- Point-and-shoot camera sensors
- Smartphone camera sensors
2. Image Processors:
Although, many ignore this fact especially if s/he new to photography. A processor inside a digital camera plays a very important role and so it’s directly proportional to the image quality.
If you are taking a snap on a jpeg(processed format) good processor helps in many ways to fix the images at inappropriate lighting.
A fast processor also comes handy when shooting a continuous photography.
But, the most underlining factor I have found using fast processor is, it allows the camera to compensate at less than ideal lighting conditions,
so you can’t ignore this feature while choosing an ideal photo cam.
3. The Camera Lens:
What’s a camera lens?
How far is it a significant part of better photography?
I have heard it a lot of times on social media as well as in my classroom. So, let me simplify.
An optical photography lens is the eye of a camera, be it for a still or cine/video camera. So, if it can’t see an image clearly you’re photograph won’t look good enough… it’s so simple.
First of all, it’s less customizable, as you can’t vary between different kind of lenses for every need.
Second to that, the opening of those lenses are way too small, so at the low-lit indoor shoot, you can’t expect a good picture.
So, there are a few things which the showroom’s sales fellow won’t tell you which determines the value for the investment you do for the device(photo camera).
Here are those you must ensure:
1. How wide it’s lens opening?:
Always look for how wide is the camera’s lens aperture.
Usually, it’s called the f-stops found on the lens rim by a unit like f/2.8 or f/4 etc.
The bigger the open smaller the denominator figure, like f/2.8 has a bigger opening than f/4 or f/5.6.
The wider the opening of a lens the better it becomes to photograph at a dim lit situation.
A wide aperture is generally considered around f/1.4 to f/3.5. It is my suggestion to start with maximum possible wide lens opening that permits your budget.
2. The image sharpness:
This is a very important aspect to consider, although you can’t assume via the specifications mentioned on the camera box label.
But, how well the final image will look like will also depend on its sharpness.
I can give you a few suggestions for that,
- 1. You can look for any photographer in your circle who has already used the device and you can judge from their image samples.
- 2. You have to look for an online retail store that will allow you to refund in case you’re not satisfied (like in case of Flipkart or Amazon, but do confirm their return terms and policy before purchasing), so you have a time period of 10 to 30days(as per the rules) to practically test whether the sharpness you want is the sharpness you get as committed.
- 3. Follow some authoritative tech or camera related journal, review website online and ask for suggestions.
- 4. You can even join the free/paid workshop programmes like Nikon, Canon, or even Camarena’s photography workshop(at e-mall, Kolkata) they do conduct those events by the experts in the industry.
These are my suggestions based on the experience and influence of a lot of expert in this field.
I would like to hear feedback from your side.
