The easiest way to trim a picture in Photoshop is to use [Clipping Tool].You can clip an image with your intuition with [Clipping Tool].
Open a picture in Photoshop. Select [Clipping Tool] from Tool Panel. Drag the screen.
When you drag it, the screen appears highlighted and eight squares appear. By draffing the squares, you can define the parts to be clipped.
You can finalize the selection by doubli clicking (or click “O” in the Option Bar).
You can also clip an image by setting the verital and horizontal size of the image in Option Bar.
Open a picture in Photoshop. Select [Clipping Tool]. Input width and height in Option Bar like in the example above. This time we input 800 x 500px.
When dragging the screen, it gets dragged while keeping the 800 x 500 dimension. When you decide the part to be clipped, double click (or click “O” in Option Bar) to finalize.
You can also trim a pivture without changing the original aspect ration.
Open the picture in Photoshop and click [Image > Graphic Resolution].
Graphic resolution dialog pops up. Check [Lock Aspect Ratio].
Input values in the width or height section.
Since the aspect ratio is locked, the other value is automatically generated when you inpit one. Click OK to finalize.
The picture is trimmied while the aspect ratio is retained. (You can check the size of the image in [Image > Graphic Rasolution]).
You can also expand an image as well as minimizing. However, the quality of an image drops when the image is enlarged.
This technique is used when you would like to get rid of blanks like below automatically in Photoshop.
[Trimming] dialog box pops up. Check the pixel color at top left, top, down, left, or right and click OK.
The blank parts were automatically trimmed!
This is a useful feature with images with blanks.
