Tutorial 2: Sharpening your photo

Sharpening is a serious issue, there are a lot of things to be said about it. However, for now, we'll stick with the practical sides of it.

To sharpen your photo do the following:

  1. Open photo in photoshop.

  2. Select filters -> Sharpen -> Unsharpen Mask.

  3. Values: Well it depends on how much sharpening would you like to achieve (yes, there is such thing as over sharpening and it can ruin your photo too!).

    Amount: The amount of the filter to apply, the higher the more sharpened the image will be.

    Radius: The filter is applied in a radial manner, therefore the larger the radius the bigger effect of the sharpening.

    Threshold: Is the amount of differences between colors that control when this filter is applied, the higher value the less pronounced the effect will be.
  4. Click the preview button to see the photo with and without the filter until you decide you like the outcome.

And voila! There you have a sharpened photo.
