Higher-resolution photography can mean higher image quality, but only if you have the right lens for it. Yes, they might have a higher MP number written on them, but it’s not what determines image quality. But then smartphones could outrank some semi-pro DSLRs. You might think the more pixels mean better images. It also refers to the amount of detail the photograph or image has when viewed at 100% on a computer monitor. Image resolution relates to the images’ print size. However, the camera sensor, processor, and even the quality of the lens you are using also play a part. Photo resolution is a factor that determines image quality. It means how many pixels are displayed per inch in the image. Image resolution is often given in PPI (pixels per inch). For example, an image that’s 2048 pixels wide and 1152 pixels tall has a resolution of 2.36 megapixels. To calculate the resolution of the image, simply multiply the width by the height of an image. Image resolution is measured in pixels and megapixels.

The more pixels, the more detailed the image is and the higher its resolution. The number of pixels of an image determines the image resolution. So a 30-megapixel camera has 30 million pixels on its sensor. This means that they are the smallest parts of a sensor or a display that you can control.ĭigital images come from thousands of tiny tiles capturing light and colour.Ī megapixel (MP) is one million ( or 1,048,576 to be precise) of these pixels. Pixels are the smallest components of a digital camera sensor. A digital camera captures images through what we know as pixels.
