To adjust the size and resolution of an image in Photoshop, which tool would you use?

• A. Image Size Dialog
• B. Resize Canvas
• C. Blur Tool
• D. The Crop Tool

Answer: (D)

The key idea is controlling the image’s actual size in pixels and its print resolution, which is done with the Image Size settings. In Photoshop, you open Image Size to specify the width and height in pixels (or units), set the desired resolution (pixels per inch or pixels per centimeter), and choose a resampling method if you want to change the number of pixels while keeping the image’s physical size or vice versa. This is the standard, direct way to resize an image and define its resolution for output.

The Crop Tool, by contrast, is focused on changing the visible area of the image and its composition. It trims pixels away to improve framing or aspect ratio, and any cropping can indirectly affect the final file size and export dimensions, but it does not provide precise control over the image’s pixel dimensions and resolution in a single, dedicated step. Resize Canvas changes the working canvas size without altering the image data, so it doesn’t actually resize the pixels themselves. The Blur Tool is for altering sharpness, not dimensions.
