Technical stuff - hints and tips
Here are some hints and tips we've picked up along the way, all designed to improve your photography.
Sharpening your digital images
1. First, zoom your image to 50% magnification. Your image window’s title bar displays the current percentage of zoom. The quickest way to get to a 50% magnification is to press Ctrl + or Ctrl – (Cmnd + or Cmnd – on a Mac)
2. Next, in the menu bar along the top of the screen, go to “filter”, scroll down to “sharpen”, and choose “unsharp mask”
3. There are three sliders in the resulting window: “amount” sets the amount of sharpening applied to the photo; “radius” sets how many pixels out from the edge the sharpening will affect; and “threshold” sets how different a pixel must be from the surrounding area before it’s considered an edge pixel and sharpened by the filter
4. Adjust as appropriate! You will see the results in the little preview window as you do it.
5. Some typical settings are
• All–purpose: amount 85%, radius 1; threshold 4
• Soft subjects (flowers, puppies, rainbows): amount 150%, radius 1, threshold 10
• Portraits: amount 75%, radius 2, threshold 3
• Snappy: amount 120%, radius 1, threshold 3
• Maximum: amount 65% radius 4, threshold 3
• Web images: amount 200% radius 0.3. threshold 0
6.Finally, examine the result. If it doesn’t look or feel right, try another setting. You’re the best judge of how you want your images to look.
