Understanding image dimensions and resolution
Before we dive into the practical aspects of resizing and cropping photos in Photoshop, we must grasp the fundamental concepts of image dimensions and resolution. These two factors play a pivotal role in determining the quality and suitability of your images for various applications.
Image dimensions
Image dimensions refer to the width and height of an image, typically measured in pixels. For example, an image with dimensions of 3000 x 2000 pixels has a width of 3000 pixels and a height of 2000 pixels.
Understanding image dimensions is crucial when resizing or cropping photos. Different platforms and media channels have specific dimension requirements, and failing to adhere to these guidelines can result in distorted or poorly displayed images.
Resolution
Conversely, resolution refers to the number of pixels per inch (PPI) or dots per inch (DPI) in an image. Higher-resolution images contain more pixels per inch, resulting in greater detail and sharpness when viewed at larger sizes or printed.
It’s important to note that resolution and dimensions are distinct concepts. An image with large dimensions (e.g., 6000 x 4000 pixels) can still have a low resolution (e.g., 72 PPI), resulting in a pixelated or blurry appearance when printed or viewed at a larger size.
By understanding these fundamental concepts, you’ll be better equipped to make informed decisions when resizing and cropping your photos, ensuring they maintain the desired quality and meet the specific requirements of your projects.
