I am somewhat new to Photoshop. Have been noticing that my prints do not match exactly what I see on my monitor. The dimensions given for the image match exactly the printed image but the prints look skewed in the portrait orientations. In other words the person in the print would look thinner than the image on the monitor. What can I do to fix this problem. Thanks for any help.
Every monitor has a native screen resolution. The native screen resolution will, by design, deliver the most accurate representation of your digital images. These values are determined by, among other things, the aspect ratio, which is the relationship between the horizontal and the vertical dimensions. If the screen resolution you've chosen has a different aspect ratio, the image will be distorted. Check the manufacturers documentation that came with your printer to determine, and set, your monitor to a resolution with the same aspect ratio and what you see should be what you get.
To change the screen resolution,
Right click anywhere on the desktop and choose Properties.
The Properties dialog box appears.
Click the Settings tab
Click and drag the Screen Resolution slider to choose a setting.
