Making it Look Sharp

Photoshop includes a filter than can be used to make a picture look sharper by increasing the contrast. This filter is usually safe to apply to the entire image.

• Make sure there is no selection by choosing "Deselect" from the "Select" menu (if possible).

• Select the "Unsharp Mask" filter from the "Sharpen" sub-menu of the "Filter" menu.

• Move the "Unsharp Mask" dialog so that you can see most of the butterfly.

• In the dialog box, set the "Amount" to 50%, the "Radius" to 3.0 and the Threshold to 5.

• Use the mouse to check and uncheck the "Preview" box so that you can compare the original image to the sharpened image.

• Repeatedly adjust the "Amount", "Radius" and "Threshold" controls until you are happy with the appearance of the image (just don't ask me to explain what they all mean). Then, click "OK".

• Save your work.
