2) Camera Resolution: How Much More is X MP vs Y MP? Further down below, I will explain what this means in regards to sensor size, pixel size, lens resolving power and technique. But thatвЂ™s certainly not the case, because it is not just about the quantity of pixels, but their quality. Judging from the above, it seems like higher resolution is always better. 4K monitors and TVs (over 8 megapixels) are getting more popular and common, which puts more burden on cameras to yield images with enough details to showcase on such high resolution devices. Monitors, TVs, projectors, phones, hand-held and other devices have seen big increases in resolution and the increased space on those devices naturally led to the need to show higher resolution images with more details.

Display Size вЂ“ during the past 10+ years, we have seen a significant progress is display technology.

As I will explain further down below, modern high resolution cameras have similar performance as their lower resolution counterparts, but their main advantages are the ability to down-sample to lower resolution to decrease the amount of noise and when shooting at low ISOs, the ability to yield larger prints.

Down-sampling вЂ“ as I have previously explained in my article on the benefits of high resolution sensors, the higher the resolution, the better the options for resizing or вЂњdown-samplingвЂќ images.

As a result, they often employ heavy cropping, which ultimately reduces resolution, which is why they tend to desire as much resolution as possible and practical. For example, sports and wildlife photographers often resort to cropping, because they might not be able to get closer to action, but at the same time do not want their final images to contain unnecessary clutter surrounding the main subject(s). Although many photographers avoid heavy cropping, sometimes it is necessary to focus on the desired subject(s).

Cropping Options вЂ“ the higher the resolution, the more room there is to potentially crop images.

In short, higher resolution is usually more desirable for the ability to print larger. Larger prints would be possible, but they would require you to either drop the PPI to a lower number, or use special third party tools that use complex algorithms to upscale or вЂњup-sampleвЂќ an image to a higher resolution, which do not always yield good results. If you wanted to create a high quality print with lots of details at 300 PPI, the print size would be limited to approximately 14.2вЂі x 9.4вЂі print (4,256 / 300 = 14.2 and 2,832 / 300 = 9.4). For example, a 12.1 MP resolution image from the Nikon D700 has image dimensions of 4,256 x 2,832. A high quality print with good details usually involves printing at around 300 PPI, so the size of the potential print is calculated by taking image width and height and dividing them by the PPI number. Printing from digital images is accomplished by squeezing a certain number of Pixels Per Inch (PPI). Basically, the more resolution, the larger the potential print size. Print Size вЂ“ usually the most important factor.

In digital photography, camera resolution is associated with a number of different factors: Sensor Size, Pixel Size and Differences in Resolution.Camera Resolution: How Much More is X MP vs Y MP?.
