TIP: Advanced Sharpening in Photoshop

This technique is quoted from Ralverd...

1) Open your image in Photoshop.

2) Go to Image>Mode (on the top toolbar) and select 'Lab Color'. (In default, you should be editting your image in RGB mode.)

3) Now that you're editing your image in LAB colour mode, go to Window>Channels to open your channels window.

4) Now that your channels window has popped up, you should see 4 different kinds of channels: Lab, Lightness, a & b. Select the 'Lightness' channel (as seen in the image).

5) Go to Filter>Sharpen>Unsharp Mask. Use an Amount of 300%, Radius 0.8 and Threshold 1. Your image should look very much oversharpened at this point, but fret not.

6) Go to Edit>Fade Unsharp Mask and keep the mode at 'normal'. Adjust the opacity with the preview box ticked (around 60-70% should give you adequate sharpening). Choose your favourite level of sharpening and click 'OK'.

7) Now go to Image>Mode on your toolbar and switch back to 'RGB Color'.


Happy photoshopping!
