Another way for sharpening

Hi people, my friend told me a great tip for sharpening pictures a few months ago, but I haven't mentioned it here. It's my mistake and I am sorry about that:) I know you know how to sharpen pictures, even you can know this way that I am going to introduce in a few lines, but do me a favour please and "hear" my words:) I just think they can be helpful.

OK, stop writing a meaningless para and go to the point:) If you use Adobe Photoshop CS3/CS4 you can sharpen images with the help of Lab Color. First, go to Image / Mode / Lab Color. Now find a Lightness in the Channels which have already changed (there are also A and B channels which are related to colors). Click on the Lightness channel and continue to go to Filter / Sharpen / Unsharp Mask. You are going to sharpen black and white image, so you will avoid problems with color, which is very good! Now it's up to you how you set other values. You can choose for example 60-80% for Amount, 2-3 for Radius and 2-4 for Threshold. But this is individual for each picture. You can just experiment what is the best for you. Then it is handy to go to Edit / Fade Unsharp Mask and reduce the amount of the whole sharpening if you think it is too much. You can reduce it for example to 50%. At the end, go again to Image / Mode and then click on RGB Color and that's it!:) Tadaa!

That's all from me. I hope that this article could be useful for you and wish you all the best - and of course - Merry Christmas!!! And a lot of presents (maybe a new photo gear:))

PS: Sing many Christmas songs because I like them:)

Hi, this is the way I do it quite often and it is effective. I learned it through the CS3 book from Scott Kelby. Thanks for the posting.

Hi, thanks for the info. I usually sharpen my images in RGB but in either the red or green channels, rarely the blue since it causes too much noise. The K in CMYK can also be helpful. Regards.
