Basic Tasks in Photoshop
Resizing and rotating
To resize an image:
You should avoid making images larger than their original size. When you do this, the image simply won't have enough detail to look good at the larger size. You can review Image Editing 101 to learn more.
- With the image open in Photoshop, select Image
Image Size.
- A dialog box will appear. Make sure Pixels are the currently selected unit size and that the Resample box is checked. The Lock icon next to the Width and Height should also be turned on, which will ensure that the aspect ratio stays the same to avoid distorting the image.
- Type the desired dimensions for the new image. When you enter the new image width, the height should be adjusted automatically to maintain the original aspect ratio.
- Click OK. The image will be resized.
If there is no Automatic option available from the Resample menu, we recommend choosing one of the bicubic resizing modes; these modes will give the best results in most situations.
Resize the example file to be 800px wide. The height should adjust automatically to 600px. Note that you must have already cropped the image using Method 2 as described on the previous page for this to work correctly.
To rotate an image:
It's easy to rotate an image in Photoshop. You can rotate images clockwise (CW) or counter-clockwise (CCW), flip the image horizontally or vertically, and even rotate by an arbitrary amount to choose a specific rotation. However, most modern digital cameras will adjust the rotation of images automatically, so you may not need to use this feature very often.
- With the image open in Photoshop, select ImageImage Rotation, then select the desired rotation option.
- The image will be rotated.
