The Advantages of Increasing Image Resolution in Photography
If you're considering upgrading your camera resolution, you probably wonder how the decision will affect your results. There are several advantages to higher resolution images, including greater forgivingness of the lens and focusing errors and less noise. You'll also see less motion blur as more pixels per degree of field of view. This is especially helpful when trying to eliminate motion blur from your images.
Lower resolution cameras have fewer focusing errors and lens resolution.
Higher-resolution cameras are notoriously tricky to hand-hold. They put more pixels per degree of field-of-view onto a subject, but focusing errors won't show up quickly. As a result, Higher-resolution cameras are harder to hand-hold and get good results. For entry-level photography, lower resolution cameras are best.
To report lens resolution, most websites avoid autofocus and instead take several shots with a focus chart at a given distance. The results reported are the ones that are closest to the zone of optimal focus. Lens resolution varies as the camera gets closer to the zone. The better-calibrated cameras are more forgiving of focusing errors and lens resolution. However, this doesn't mean that lower-resolution cameras are unreliable.

Lower resolution cameras are more forgiving of noise.
Lower resolution cameras produce smaller files than higher resolution ones, making them easier to handle during post-processing. Moreover, these smaller files are less demanding on computer hardware and exceptionally lightweight ultrabooks. Therefore, lower resolution cameras are more practical for sports, journalism, and other challenging photography fields. Moreover, low-resolution images do not require resizing or downsampling, making them much smaller and easier to work with.
For example, a sensor with 14 million pixels will produce more digital noise because the pixel size will be smaller. This, in turn, causes distortion. Furthermore, long exposures and high shutter speeds create noise in the form of static and luminance noise. In addition, these camera types introduce more digital noise and luminance noise when using long shutter speeds and high ISO. Fortunately, in-camera noise reduction can help mitigate the effects of these two types of noise in photography.
Down-sampling reduces noise in images.
Down-sampling an image makes it appear less noisy, but it does not reduce noise. Instead, it reduces image quality by removing detail and high-frequency noise. Though it is convenient to compress images, this process is a bad idea. If you want to reduce noise, you should consider resampling the image instead. Then, you can save storage space and maintain image quality.
Bilinear interpolation (BI) is the most effective and most straightforward among the various methods for down-sampling images. However, the sharper downsampling algorithms aren't any better. According to Bart van der Wolf, who has studied the algorithms used for image resampling, applying an AA filter at a sigma of 0.2 or 0.3 over the magnification is better.
A higher resolution is better for post-processing.
The higher the resolution of an image, the more detail it contains. Each digital picture has a specific amount of pixels. The greater the resolution of an image, the more pixels it possesses. Data is added to a picture through upsampling, downsampling, and resampling. Lower processing artifacts are associated with higher resolution. Increasing the resolution of your image can be difficult, however.
One way to increase resolution is by increasing the megapixels of the image. Higher resolutions allow you to crop the photo and improve its composition. A higher-resolution image will enable you to work with more detail without reducing quality. If you are editing your images on a computer, higher resolution images will allow you to crop your image without losing details. Higher resolutions also give you more playroom for composition and aspect ratio adjustment.
As previously mentioned, image resolution is a measurement of the number of pixels in an image. In photography, the higher the resolution, the higher the quality of the photo. Generally speaking, higher resolution is better for post-processing. For example, if you are looking for a picture to use as computer wallpaper, you should save it in a 1920×1080 resolution. Higher resolutions are possible with high-megapixel cameras, but they can destroy the original look of the picture.
