Use Photoshop to create a canvas in inches that is 12″ x 12″ with a resolution of 200.
Create a picture.
Use each piece at least once.
These images to be used for Photoshop practice exercises only. Right click to copy this image to your clipboard. Next, open a new Photoshop canvas and leave the dimensions that Photoshop recommends, as Photoshop is aware of the size of the object on your clipboard. Paste the image into the new canvas.
