Use Photoshop’s Unsharpen Mask to Improve Images
What a difference! Above is the image I used originally in one of my “What’s on My Needles” posts a couple of months ago.
Below is a corrected image based on tips found at Digital Photography School. 
It seems counter intuitive to some people to select “unsharpen” when the outcome they desire is one of greater sharpness. Even if you understand the concept behind this, it’s knowing the proper settings for the unsharpening mask in Photoshop that trip you up.
If you want to improve your images, scoot on over and watch the video.

The second one is clearer than the first. Minute details were taken cared of and I can’t see any blurred part in the second picture. It’s really best to sharpen details in a picture. Please share with us your secret.

The site I mentioned, Digital Photography School, is where I found the tutorial used in the corrections applied to the second image. The link is in the original post.
