Certified Professional Photographer (CPP) Practice Exam

Question: 1 / 465

Resolution is defined by the number of __________________ per inch.

Bits

Pixels

Resolution is defined by the number of pixels per inch. This concept is critical in photography and imaging as it determines the level of detail an image holds. Higher pixel density typically results in sharper images with more detail because there are more individual pixels contributing to the overall representation of the image.

While options like bits, colors, and bytes relate to digital imaging, they do not define resolution. Bits refer to the amount of information in a pixel related to its color depth, colors refer to the range of hues a device can reproduce, and bytes deal with the amount of data being managed, which can indicate file size but not the inherent resolution of an image. Thus, understanding resolution as pixels per inch is essential for evaluating image quality in both photography and printing.
