applies to raster digital images, film images, and other types of images. Higher resolution means more image detail.
Pixel Picture Element - a single point in a
raster image, or the smallest addressable screen element in a display device; it is the smallest unit of picture that can be represented or controlled.
MP – Megapixel – Number of pixels in an image.
Layer Layers are used in digital image editing
to separate different elements of an image. A layer can be compared to a transparency on which imaging effects or images are applied and placed over or under an image.
