The last task in correcting and enhancing digital photographs is to sharpen them.
Sharpening digital photos helps to bring back some of the original crispness lost during the correction process.
In some cases, it can be used to fix images that seem slightly out of focus.
In part one, we covered how to sharpen images using the Unsharp Mask Filter before printing.
This section delves into using the Smart Sharpen Filter which can be very useful to sharpen out of focus images.
Because today’s digital cameras produce such a large sized file
the proper magnification to view your photo during sharpening is around fifty percent.
For us we are going to view them at around sixty-six percent.
But normally you would want to view them at fifty percent.
Now to get started, let’s open up the data file smart_sharpen.psd.
If you have already done so, let’s choose the Smart Sharpen Filter by first clicking on the Filter menu.
Then scroll down to Sharpen and select Smart Sharpen.
Once the smart sharpen dialog box opens up click on the Sharpen tab.
The amount controls the amount of sharpening and the radius determines how many pixels the sharpening will affect.
What we want to do now is lower the amount value to about sixty to seventy percent and set the radius to about one.
Click on the remove drop down arrow and select Lens Blur.
Removing lens blur allows the Smart Sharpen Filter to better detect the edges
create less color hallows and just give a better overall sharpened image.
Once you have done that let’s go ahead and click on the Ok button.
Let’s open up the History Panel so we can see the before and after the smart sharpen filter has been applied
and to do that let’s go to the Window Menu.
Select History, then on the History Panel click on the Open state.
That’s what the image looked liked before the smart sharpen filter was applied.
To revert back go ahead and click on the Smart Sharpen state.
