You can crop dimensions in Photoshop by using the Crop Tool and specifying the desired width and height, or by selecting a preset dimension. Here's a breakdown:
1. Selecting the Crop Tool:
- Locate the Crop Tool in the toolbar (it looks like two intersecting right angles). You can also press the "C" key to select it.
2. Setting Dimensions:
- Width and Height Fields: After selecting the Crop Tool, look for the options bar at the top of the screen. You'll find fields for "Width" and "Height." Enter your desired dimensions (e.g., "1920 px" for width and "1080 px" for height).
- Resolution Field (Optional): You can also specify the resolution in the "Resolution" field (e.g., "300 ppi" for print quality).
- Preset Dimensions: The options bar may also include a dropdown menu with preset dimension ratios or sizes (e.g., "4x6", "5x7", "Square"). Select a preset if it meets your needs.
3. Adjusting the Crop Area:
- After entering the dimensions, a crop box will appear on your image. Drag the corners and sides of the crop box to adjust the area you want to keep. Photoshop will constrain the crop to the dimensions you entered.
- Click and drag inside the crop box to reposition the image within the crop area.
4. Applying the Crop:
- Press the Enter key or click the checkmark icon in the options bar to apply the crop. The image will be cropped to the specified dimensions.
- To cancel the crop, press the Esc key or click the cancel icon (usually a circle with a line through it) in the options bar.
Example:
Let's say you want to crop an image to a square with dimensions of 500x500 pixels:
- Select the Crop Tool.
- In the options bar, enter "500 px" in both the Width and Height fields.
- Adjust the crop box on your image to select the desired square area.
- Press Enter to apply the crop.
Important Considerations:
- Deleting Cropped Pixels vs. Hiding: By default, Photoshop deletes the cropped pixels. If you want to keep the cropped pixels (non-destructive cropping), check the "Delete Cropped Pixels" option in the options bar before cropping. If unchecked, the cropped area will be hidden, but you can later adjust the crop without losing those pixels.
- Units: Make sure you specify the units (e.g., px, in, cm) after the numbers in the Width and Height fields. If you don't specify a unit, Photoshop will use the default unit (usually pixels).
