Digital Imaging

Pixels

In digital imaging, a pixel is the smallest unit of a digital image, which can be thought of as a tiny square that uses a specific color. An image file is made up of thousands and thousands of pixels, but because each pixel is so small, you normally won't notice them unless you zoom in. When referring to the height and width of an image, we talk about its dimensions. For example, an image that is 500 pixels wide and 200 pixels high would have dimensions of 500px by 200px. It's also important to note that the orientation of an image can be either landscape (wider than it is tall) or portrait (taller than it is wide).

Resolution

Resolution in digital imaging refers to the amount of detail contained in an image. The higher the resolution, the more quality the image will have. Resolution is particularly important when considering printing or resizing an image. While you can often make an image smaller without noticing much difference in quality, making an image larger than its original size will usually result in a noticeable loss of quality. Low-resolution images can appear blurry and lacking in detail when resized, and may also look blocky or pixelated. Understanding the basics of image file formats, including the most common ones you'll encounter when working with images, is important for managing resolution in your digital images.

Image Editing Software

There are a variety of image editing software options available for digital imaging, catering to different needs and budgets. Some popular choices include:

These are just a few examples of the many options available for digital image editing. The choice depends on your specific needs, budget, and the type of images you'll be working with.
