What term is used to describe the overall file size affected by resolution and bit?

1. Quality

2. Length

3. Depth

4. Height

The correct answer is: Depth

The term that describes the overall file size affected by resolution and bit is "Depth." In photography and digital imaging, depth typically refers to the "bit depth," which indicates the amount of information stored for each pixel in an image. Higher bit depth means more color information can be captured, allowing for more subtle gradations in color and improved overall image quality. As the bit depth increases, the file size tends to increase as well because more data is being saved for each pixel. Resolution, which refers to the number of pixels in an image (width and height), also impacts file size; more pixels contribute to a larger overall file. Therefore, both resolution and bit depth are key factors that influence the size of an image file. Understanding this concept is crucial for photographers who want to manage their digital assets effectively while ensuring high image quality.
