Black and white photos are a timeless classic, but what is the resolution of these photos? On average, black and white photos have a resolution of 300 dpi (dots per inch). This means that there are 300 tiny dots in a linear inch of the photo. The higher the resolution, the clearer the image becomes. For example, a photo with 600 dpi will be twice as sharp as a photo with 300 dpi. When selecting a resolution for your black and white photo, it's important to consider the size of the image and the print size you desire. Higher resolution images are better for larger prints.
