A camera with 4000x6000 photosites is referred to as what kind of camera?

1. 24-megapixel camera

2. 36-megapixel camera

3. 12-megapixel camera

4. 16-megapixel camera

The correct answer is: 24-megapixel camera

A camera with a resolution of 4000x6000 photosites has a total pixel count of 24 million pixels, calculated by multiplying the width (4000) by the height (6000). This resolution is equivalent to 24 megapixels, as one megapixel is defined as one million pixels. Thus, referring to this camera as a 24-megapixel camera accurately reflects its total pixel count. Understanding how to calculate megapixels from dimensions is crucial for identifying camera specifications and comparing image quality, as higher megapixel counts typically lead to more detailed images, particularly when enlarging or cropping photos.
