![]() ![]() People regularly discuss digital images in terms of DPI, which stands for Dots Per Inch. So, unless you resample (which means you artificially alter the pixel dimensions in a photo editing program) or crop the image, your image will always be 1200x1800 pixels. That means our digital image is 1200 dots high by 1800 dots wide. For example, let’s say we have a digital image that is 1200x1800 pixels (dots). The total pixel dimensions of an image will tell you how many total pixels (dots) the image is made up of. There are three different ways to describe a digital image’s resolution that essentially mean the same thing: And, the mor e dots a digital image has, the clearer the image, which is why you want to use high resolution (lots of dots) images to make Photographic Prints and Fine Art Prints. Digital images are made up of square -shaped dots (pixels). the resolution of the image dows not changes when its DPI value is changed. The DPI (dots per inch) of an image is simply metadata embedded inside the image header. This number is calcul ated using your digital image’s pixel dimensions and digital image size. Grayscale images are more nuanced and subtle than black and white images, and can convey more information.DPI of digital image: DPI means Dots Per Inch. In summary, black and white images only use two colors while grayscale uses a range of shades of gray to represent different levels of brightness or color.This is done by defining a grayscale value for each color channel, which is determined by the intensity of the color. Grayscale images are created by converting the color image into a monochrome image.Grayscale images have a much more subtle range of tones, with areas that are very light gray and areas that are very dark gray, and many shades of gray in between. Grayscale, on the other hand, refers to images that use a range of shades of gray to represent different levels of brightness or color.These images typically have a very high contrast, with areas that are completely black and areas that are completely white, with no shades of gray. Black and white refers to images that use only two colors: black and white.Black and white and grayscale refer to different ways of representing images with limited colors.What is difference between black and white and grascale? Enhancing the overall quality of an image: By removing the color information, grayscaling can lead to better image quality, since color noise can be removed.Creating a sense of nostalgia or vintage feel: Grayscale images can evoke a sense of nostalgia or vintage feel, which can be used to create a specific visual effect.Enhancing readability: Grayscale images can be easier to read and interpret than color images, especially for people with certain visual impairments. ![]() Creating a specific visual effect: Grayscale images can have a different look and feel than color images, which can be used to create a specific visual effect. ![]()
