Re: Sharpening Clear/white line

If you are using Photoshop and unsharp mask, after sharpening try going to Edit>fade unsharp mask. Change the blend mode to Luminosity and click OK.

Re: Sharpening Clear/white line

first focus your lense before you take a picture. I like to make a copy in layers, change to luminosity mode and use a sharpening filter. Then reduce the opacity down and click it off and on to see how much I need. Doing it in layers gives you the ability to use other forms of sharpening and compare. And at last if it needs it, a little selective color contrast adjustment instead of sharpening. It happens.

Re: Sharpening Clear/white line

When you apply sharpening (e.g. unsharp mask, or smart sharpening) you must ensure that you are using at least 100% magnification so you can see the real effect at pixel level. You can then more readily detect oversharpening which certainly causes the halos that you are seeing. There are some other methods of sharpening which avoid these halos but may cost (e.g. Topaz In focus).

Re: Sharpening Clear/white line

Could be just a plain case of oversharpening! I use the unsharp mask a lot but I always make sure theres a big image on my screen so I can see at an instant whether I have over done it, sometimes some images need very little sharpening.......

Re: Sharpening Clear/white line

Lines and smooth surfaces work well with highpass. I use an action, a higher number on the highpass pop up and then use hardlight mostly. I end up useing this for spot sharpening. I think it works well for certain areas because you can over sharpen solid type colors and lines and make it look good. "TBH" I use sharpening in raw and then when I resize anymore with very little extra. Does that mean I have finally learned how to take better pictures ? I think so, but sharpening is like a sickness and it is hard not to use it. Try bevel filter like the highpass.

Re: Sharpening Clear/white line

Use High-pass most of the time Boofers with extra mask like you say its good for highlighting certain points, think its just me maybe be a bit over-fussy
