2. Understanding Image Resolution and Size

Image resolution and size are two distinct but interconnected concepts that affect the quality and usability of digital images. How do these elements influence your work? Understanding the difference between resolution and size is key to effective image resizing. Resolution refers to the number of pixels in an image, typically measured in pixels per inch (PPI) or dots per inch (DPI). Size, on the other hand, refers to the physical dimensions of the image when printed or displayed. High resolution means more pixels, resulting in a sharper, more detailed image, but also a larger file size. Low resolution means fewer pixels, leading to a less detailed image and smaller file size. Here’s a breakdown:

3. Preparing Your Image for Resizing

Before you dive into resizing, it’s important to prepare your image to ensure the best possible outcome. What steps should you take? Preparing your image involves a few key steps. First, assess the current state of your image. Check for any imperfections such as dust, scratches, or blemishes that may become more noticeable after resizing. Make any necessary corrections using Photoshop’s retouching tools, such as the Spot Healing Brush or Clone Stamp. Next, consider the intended use of the resized image. This will help you determine the optimal resolution and dimensions. For instance, if you plan to print the image, you’ll need a higher resolution than if you’re using it for a website. Finally, save a copy of your original image before making any changes. This way, you can always revert to the original if needed. Follow these steps:

• Assess Image Quality: Look for imperfections and correct them.
• Determine Intended Use: Decide on the optimal resolution and dimensions.
• Save a Copy: Always keep a backup of your original image.
• Adjustments: Make preliminary adjustments to color, contrast, and sharpness.

4. Opening Your Image in Photoshop

Opening your image in Photoshop is the first step towards resizing it. How do you get started? Launch Adobe Photoshop on your computer.
