DPI, Resolution, and Pixel Count: What's the Difference?

When it comes to photo scanning, you'll often hear terms like DPI, resolution, and pixel count. While these terms might sound confusing, understanding them is crucial for ensuring your scanned images are of high quality. Let's break down these concepts:

DPI (Dots Per Inch):

What it is: DPI refers to the number of dots of ink or toner a printer can place in a line within a one-inch space.

Why it's important: A higher DPI means a sharper image. For photo scanning, a DPI of 300 is generally considered a good standard for high-quality prints.

Image Resolution:

What it is: Resolution measures image detail, often expressed in pixels per inch (PPI).

Why it's important: A higher resolution means more detail in the image. A resolution of 300 PPI is ideal for most purposes for photo scanning.

Pixel Count:

What it is: Pixel count refers to the total number of pixels in an image.

Why it's important: A higher pixel count allows for larger prints without sacrificing quality. However, it's important to note that pixel count alone doesn't determine image quality. DPI and resolution also play significant roles.

Why These Matter for Photo Scanning:

Understanding these terms helps you make informed decisions when choosing a photo scanning service. By knowing the ideal DPI, resolution, and pixel count for your specific needs, you can ensure that your scanned photos are crisp, clear, and ready for future enjoyment.
