This is a method that I ran across on the web for resizing/sharpening images for the web. I'm sure there are better ways to reach the same result, but I find that this is quick, easy and fairly consistent. The basics are presented here and there are a multitude of tweaks to make it more effective.
- Take full res, unsharpened image and reduce size to approximately one half the length of the longest edge in pixels. This size will vary on an image by image basis so some trial and error may be needed to find the sweet spot. Apply the SHARPEN filter twice or even three times at this size. I use the generic FILTER>SHARPEN with the default bicubic option.
- This will create a very oversharpened, noisy, mid-size image.
- Futher reduce image size to your web preference, such as 800 pixels on the longest edge.
- When reduced, Photoshop applies an ultra-fine USM.
- A very light final sharpening may be done if needed.
Your mileage may vary. :D
