what does everyone reckon as the best settings for unsharp masking your pics
or does it vary from pic to pic or do you have a set ratio that you use all the time |

Depends on how much it needs sharpening, if taken properly then only a little say 0.4 at 60%?

| Are you talking about the settings in your camera or in Photoshop? |

There are so many variables involved. Camera, lens, resolution of image, subject matter etc. etc.
With my Sony 707 on a 5MP image resized to 640x480, I had great results using radius 0.3px at 100% threshold 0.
Applying those settings to an 8.2MP image resized to 640x427 from my 20D needs much more sharpening. Sometimes I bump the radius up to 0.6 at >250% threshold 0. Only if I really need fine tuning, do I crank up the radius and sharpening extremely high and smooth it out with the threshold levels.
My 2 cents. |

Zackly what Brandon said.
with your camera .5 radius, 250-300%, 0 threshold is parfait. |

For the originals yeh? I think this would look bad on resized 640x480 challenge submissions... For them I use 0.3 radius, 100-170%, 0 threshold, or 1-2 threshold if the image has a lot of noise.

correct as usual Ben; those are for full res pix. re-sized I wouldn't go much above .3 radius either.
*edit for spelling like a drunken sailor.

250-300%!?!?
That's crazy. I never get above 100 with my D. Rebel. But that's just me :) |

all depends on the radius... |

For DPC-sized images I use between 66-88%, a 0.6 - 0.8 dia setting, and a TH of 5-7. I will sometimes make two applications of the filter with a lower setting.
For print size images, I usually raise the diameter setting to about 1.3 or so, but usually leave the other settings as they were.
I have some examples of different amounts of sharpening in this pBase Gallery |

I have my camera set on Soft, or minimal sharpening
Then i do a 500%, .1, 0.
i then edit or whatever. If printing, I rarely do any sharpening at all.
For DPC or web, i start with 150-250% range and .2 to .4 (depends on what the image is) and th of 7 or so.
If the image has a haze to it, I do 30-40%, 60-80 radius and 1 th. This is a recent discovery and it helps many images, but might blow out the highlights if the image is a bit overexposed to begin with.

When I first got my D70, I tested every in-camera sharpening setting with Photoshop. The very best results I could get were with no sharpening in-camera and doing the sharpening case-by-case in Photoshop.
Photoshop sharpening beats in-camera sharpening hands down, and there are far more options available anyway: high-pass sharpening, local contrasting as well as the traditional types. |

It varies from pic to pic and also with the reason for sharpening.
If you are sharpening to replace the sharpness lost by the digitizing process, then the settings are camera specific; but likely always be the same for that camera -- this is what most of the above sounds like.
If you are sharpening to bring out some aspect of the photo, such as the eyes, salt-n-pepper hair, or fabric of an outfit (for portrait work) the sharpening is best done with a mask and settings that are very image specific.
Then, when you want to present the image the sharpening will be dependant upon the method of presentation. For example, as stated above, the sharpening for a DPC sized web image is quite different than for the full sized image. Likewise, the sharpening will vary for prints depending on the size and resolution of the desired printing.
The above is formalized and discussed in much greater detail with examples in this article, "Thoughts on a Sharpening Workflow".

You may find the portion of the article discussing the use of the layer blending options helpful; it discusses how to set them to protect the highlights and shadows areas from damage.

One thing I always do when using USM .....
Convert to Lab Colour, then go to Channels and select the Lightness channel.
Sharpen on the lightness channel and you can, if required, apply a higher level of USM before that awful halo effect appears.
Convert back to RGB when done.
Works a treat.
As for settings ... yeah, I'd agree with most of the ones above, depending on the photo in question.
