How to Convert 8-Bit Images to 16-Bit Images in Photoshop Elements 9
In Photoshop Elements, you can convert 8-bit images to 16-bit images if you don’t have a digital camera capable of capturing 16-bit images. You can convert any image taken in 8-bit mode with a digital camera or a scanner to a full 16-bit image.
1Open Photoshop Elements in Edit Full mode.
If the Welcome screen is displayed, click the Edit button to access Edit Full mode.
2Choose File→Open As.
The Open As dialog box appears.
3Choose Camera Raw from the Open As drop-down menu.
You’ll find the Open As drop-down menu at the bottom of the dialog box.
4Click Open Copy in the Camera Raw converter.
Don’t make any adjustments in the Camera Raw converter. As yet, the photo is not a true 16-bit image.
5Choose Image→Resize→Image Size.
The Image Size dialog box appears.
6Select the check boxes for Constrain Proportions and Resample Image.
Both the Width and Height are sized when the Constrain Proportions check box is selected.
7Choose Percent from the Width drop down-menu and type 71 in the text box.
By setting the value to 71 you get one half the number of pixels in the resultant image, which downsamples the image by 50 percent.
You now have a true 16-bit image.
