Re: [photoshop-beginners] Re: Will Layers Improve Sharpness?

Not to be smart or anything like it....

When you adjust the layer you will effect the image.  The apparent sharpness will be reduced as the contrast of the image is reduced by the screen layers.

From the PS help files:

Screen

 

Looks at each channel's color information and multiplies the inverse of the blend and base colors. The result color is always a lighter color. Screening with black leaves the color unchanged. Screening with white produces white. The effect is similar to projecting multiple photographic slides on top of each other.

This translates to the highlights stay where they are as the shadows open up with each layer copy.  Sharpening an image that has been screened might sharpen the noise that will become apparent in the screened areas.  Improper sharpening will induce colored halos.  There are really good books out there on how to properly sharpen images in Photoshop.  I am simply showing 3 different sharpening processes that you already have within Photoshop and need not pay additional money for.

If you are satisfied with your images then the sharpening you use is right for you....

i was not suggesting that an out of focus image can be made better by sharpening it, what i am saying ..that ok..best example i can give, i make a layer in photoshop, exact duplicate of original, and then i go to set it to"screen" the entire layer, which lightens it up, then i will copy that layer if i need to make it a bit lighter and lower the opacity from there..so when i do this, i can see a difference in the beginning to where nothing was done to the two layers i add....so this is where i am left with an image that is somewhat less than it was to begin with sharp wise..and i then take it into another program entirely, after saving as a jpg, and sharpen it...i dont like the sharpen parts of the photoshop, as i find it doesnt clear it as much as it just emphasizes the outer linings, and when i sharpen in the other program, i dont have to also blur certain parts of it..if that makes sense

maybe i go the long way...i dont know
