How to Adjust the Crop Box in Photoshop CS6
You can use the crop tool in Adobe Photoshop Creative Suite 6 to adjust the size of your image. Once you have cropped your image, you can adjust your crop box by dragging the handles or sides.
When you hover your mouse over any handle or the crop box itself, your cursor changes to a double-headed arrow, indicating that you can drag.
The default movement of the crop box in relation to the image itself has changed in Version CS6. Not only does the crop box adjust as you size it, but the image also moves. The reason for this is because Photoshop is keeping the crop box centered on the canvas.
This change can be disconcerting for old time Photoshop users. If you don’t like the new movement, select Use Classic Mode from the Set Additional Crop options drop-down menu, or simply deselect Auto Center Preview. You will then be able to adjust the Crop box without the image moving underneath.
Select the Show Cropped Area option to display the portion of the image you are cropping away. Deselecting this option will not display that portion and for some users can help to better frame what you want to retain.
If you move your mouse outside the crop box, the cursor changes to a curved, double-headed arrow. Dragging with this cursor rotates the image. Your canvas will now auto expand, and your crop box contracts to fit the image.
This feature can be useful when you want to rotate and crop a crooked image at the same time. Just be aware that rotation, unless it’s in 90-degree increments, resamples your image — which, if done repeatedly, can damage your image. Getting the rotation right the first time around is for the best.
The Crop tool options bar now includes a Straighten option. To straighten the image, simply click the Straighten button on the Options bar and drag the cursor along your desired horizontal axis.
