![]() There are dozens of image formats, but Windows Scan and Windows Fax and Scan only offer you a handful. You can always covert a scanned image to grayscale or black and white later, but adding color to grayscale images is substantially more difficult and requires an artistic eye to do well. Grayscale images will take up less space, so if you don't care about the color, use grayscale. Any documents with images should be scanned in grayscale or color, depending on your needs. Grayscale scans fall in the middle.īlack and white will do just fine if you're only scanning text documents - it might even help if you're scanning faded text with poor contrast. Color: All of the color and shading information is preserved.Īll other things being equal, black and white scans will have the smallest file sizes, and color scans will have the largest file sizes.If you have dark green on your document, it'll be changed to dark gray. If you have light blue on the page, it'll be changed to light gray. Grayscale: All color information is removed, but shading information is kept.Black and White: All color and shading information is removed - any colors or greys are converted to black. ![]() Here's what those terms mean practically.

For context, the drawing of the pig is only about an inch long. Here's an example using a photorealistic drawing a pig on a 8.5''x11'' piece of paper. More is generally better, but there comes a point where you don't really gain anything from cranking up the DPI. Using a higher DPI means the image can be blown up to larger sizes without becoming obviously pixelated. If you're scanning old film negatives, slides, high-quality prints, or artwork, you'll probably want to go as high as you can to extract all of the available details. Higher DPI settings also result in slower scans. The higher the DPI, the larger the image. If you scan the same document at 600 DPI, it will have a resolution of 5100圆600. As an example, if your scanner has an area of 8.5''x11'' and you scan a document at 200 DPI, the resulting image will have a resolution of 1700x2200. DPI determines the resolution of the image that will be created when you scan something. Good luck.The most important option is the dots per inch, or DPI, setting.

And you can print the report so one can take it to a repair shop if needed. The purpose of this program is an internal audit of your computer. Especially if you need license data or an original key code. ![]() Even if there is a charge now, worth every penny in my opinion. It has been at least 3 years since we bought a new computer, it was a free download then - I hope it still is. I have used it over many years and may computers, including operating systems MS6 - 7- 10, ME, Vista, XP, etc. However, if you can do so, I recommend downloading a program called Belarc Advisor. If you have the listing number and a good lawyer, you can file a legal request in court to have them research it - but that would cost more than the computer would be worth is my guess.
