Do Megapixel Really matters??

What are Megapixels?

One megapixel is equal to one million pixels in an image. You can easily calculate the megapixels of your camera by looking at the width and height of the image in pixels. For example, if I click an image using my Canon 5D Mark III, I get an image of 5760 × 3840px. So by multiplying 5760 by 3840 pixels, we get 22,118,400 pixels which mean that the image that I clicked has 22.1 megapixels.


How many pixels do you actually need?

The requirement of megapixels depends on the final use of the image clicked by you. There are three major ways you can use your images after clicking them from your camera:

  1. View it on your monitor

If you click images just to view them on your monitor, you hardly need a high megapixel camera. Suppose you own a 19-inch 1920×1080 resolution monitor, all you would need is a 2-megapixel camera to view the images clearly.

So even if you would be cropping your images a bit after clicking them, you can use a 5-6 megapixel camera to view images without any compromise in display quality.

  1. Upload on social media

If your end use of clicking images from your camera is to upload them on social media platforms such as Facebook and Instagram, all you need is a 2-megapixel camera. But why?

No matter how high-resolution your image is, Facebook and Instagram would downsize them to their respective maximum resolution.

Facebook – Ideal image resolution

Square image: 2048 x 2048 pixels

Horizontal image: 2048 x (as per the image ratio) pixels

Vertical image: (as per the image ratio) x 2048 px

To upload any image on Facebook, be it in square, horizontal or vertical proportion, you only need a 0.2-megapixel file. Even if you try uploading a 4000 x 4000 pixel image, it would automatically be downsized to 2048 x 2048 pixels if you are uploading with the high-resolution option checked.

Instagram – Ideal image resolution

Square image: 1080 x 1080 pixels (maximum)

Horizontal image: 1080 x 566 pixels (maximum)

Vertical image: 1080 x 1350 pixels (maximum)

If you upload any high-resolution image on Instagram, be aware of that fact that the image will be compressed into the respective maximum proportion as mentioned above. So if you upload a 4000×4000 pixels image, it will be downsized to 1080 x 1080 pixels.

Understanding ISO Sensitivity

By -
Image
ISO refers to the senstivity -the signal gain-of the camera. In simply, ISO is simply a camera setting that will brighten or darken a photo. As you increase your ISO number, your photos will grow progressively brighter. For that reason, ISO can help you capture images in darker environments, or be more flexible about your aperture and shutter speed settings. WHAT IS BASE ISO? The lowest native ISO on  camera is  “base ISO”. This is a very important setting, because it gives you the potential to produce the highest image quality, minimizing the visibility of noise as much as possible   ISO VALUES ISO 100 (low ISO) ISO 200 ISO 400 ISO 800 ISO 1600 ISO 3200 ISO 6400 (high ISO) LOW VS HIGH ISO NOISE VISIBILITY   Take a look at the comparison below. Pay attention to the level of noise (graininess and    blotchy colors) in the images: The difference is clear – the image at ISO 3200 has much more noise than the one at ISO 200 (which I brightened with a long s...

Difference Between Raw and Jpeg

  WHAT IS  RAW IMAGE? A RAW format file is basically an unprocessed file captured directly through the camera sensor. The image captured in RAW format is usually dark and flat in contrast as the file is not processed at all, as in the case of a JPEG file. While viewing on your camera’s LCD screen, you would hardly find any difference between the RAW and the JPEG files. But the moment you open the files on your desktop or the laptop, you might me disappointed by the look of the RAW file because of its flat color tones and contrast. At the first look, you might fall in love with the JPEG file, but the truth is that the RAW file holds all the details ranging from the contrast to white balance. Using the RAW file, you can completely change the white balance, brightness, sharpness, contrast, etc., of the image, without degrading the quality. In order to access the RAW file on Adobe Photoshop or Adobe Lightroom, you would need to download the free ...

What is Shutter Speed??

WHAT IS SHUTTER SPEED? Shutter Speed is the length of time the camera shutter is open,exposing light on to the camera sensors. Shutter Speed is one of the three elements of Exposure Triangle that are responsible for correctly exposing the photos. Shutter speed decides whether to freeze the subject in your frame or to capture a long exposure moment. In this blog post, I am going to shed some light on what exactly the shutter speed is and how you can control it to click various kinds of photos. How Shutter Speed Is Measured?? Shutter speed are measured in fractions of a second. Most modern DSLRs and mirrorless cameras can handle shutter speeds of 1/4000th of a second at the fastest, while some can handle even quicker speeds of 1/8000th of a second and faster. On the other hand, the longest available shutter speed on most DSLRs or mirrorless cameras is typically 30 seconds. You can use a longer shutter speed by using external remote triggers, if necessary. Types Of Shutter Speed 1) Fast S...
