If the image was resampled, you should now resharpen it (see pages 296–300).
As a result of resampling, the pixel dimensions The Bicubic (Best for Smooth Gradients), Bicubic Smoother (Best for Enlargement), and Bicubic Sharper (Best for Reduction) options cause the least reduction in image quality. Also, from the menu at the bottom of the dialog, choose a resampling method for the way in which Photoshop reassignsĬolor values based on the values of existing pixels. If the resolution is greater than 300 ppi, check Resample Image, then enter a Resolution of 300. Because the pixel count didn’t change, the image size and quality were preserved. When you lower the Width and Height in step 4, the resolution will increase automatically.ī When we reduced the photo size to 6 × 8.533 inches via the Image Size dialog, the resolution increased automatically to 300 A Because you need to increase the image resolution, uncheck Resample Image.

We’ll show you how to resize three common types of files for print output - low res/large dimensions, high res/small dimensions,Īnd medium res/small dimensions - and how to resize a file for Web output. The resolution of your image - the number of pixels per unit of measure, which is normally per inch, or “ppi.” For print output, you’ll need to be aware of You’ll need to be aware of the pixel dimensions, or pixel count, of an image. When working in Photoshop and for Web output, Pixels, short for “picture elements,” are the building blocks that make up a digital image - the tiny individual dots that a digitalĬamera uses to capture a scene or that a computer uses to display images onscreen. Resampling isn’t a problem for Web output. The file is resampled, although it can be remedied somewhat by applying a sharpening filter afterward (see pages 296–300). This can be a problem for print output, depending on the output resolution and how drastically Way to get those pixels back is by clicking a prior state on the History panel before closing the file.
Resample a file as you decrease its resolution (downsample it), and pixels will be deleted. If you resample a file as you increase its resolution, pixels will be added to it and its storage size will You will need to resample a file if it contains too few or too many pixels to meet the resolution requirement of your target In either case, so the image quality isn’t diminished. Size (and thereby lower the resolution) or increase the resolution (and thereby lower the print size). You can keep the pixel count constant as you increase the print Pixel count to increase its print size or print resolution. In Photoshop, you can take advantage of a file’s high Some input devices (e.g., digital cameras that capture 8 megapixels of data or more and high-end scanners) produce files withĪ higher pixel count than is needed for most standard printing devices.
