Classify Photo Resolution For Free

The Rijksmuseum in Amsterdam has released an interactive photo of The Night Watch painting by Rembrandt in a staggering resolution of 717-gigapixels. The museum claims it is the highest resolution photo of artwork ever captured.

To check the pixel count of an image: Right-click on the image (or, on a Mac, control-click). Choose Properties or Get Info. Click the Details tab. (or, on a Mac, More Info). You'll see the image dimensions in pixels.

Image resolution is typically described in PPI, which refers to how many pixels are displayed per inch of an image. Higher resolutions mean that there more pixels per inch (PPI), resulting in more pixel information and creating a high-quality, crisp image.

In many cases, the best resolution for printing is 300 PPI. At 300 pixels per inch (which roughly translates to 300 DPI, or dots per inch, on a printing press), an image will appear sharp and crisp. These are considered to be high resolution, or high-res, images.

Step one: When you find your image, don't open it. Instead, right click on the photo and select Properties. Step two: Once you're in Properties, click on the Details tab. Step three: Scroll until you see the resolution or dpi of your picture.

Hi-res images are at least 300 pixels per inch (ppi). This resolution makes for good print quality, and is pretty much a requirement for anything that you want hard copies of, especially to represent your brand or other important printed materials.

Scientists building the world's largest digital camera have captured the highest resolution images ever taken in a single shot, reports Mike Wall for Space.com. The photos are 3,200 megapixels (3.2 gigapixels). Displaying one of them at full size would require 378 4K ultra-high-definition TVs.
