I would also like to understand the Unsharp Mask settings. I have never used photoshop but I can't imagine that e.g. the settings Amount 85% Radius:1 Threshold:4 would turn out the same in photoshop as they will do in Gimp (i.e the result of the image after having used USM with the same settings). So if anyone on this list dare to give a rough translation between photoshop USM settings and GIMP USM settings I would be happy as well.

Thanks for the links Dan they are great sources. But none of them really tells me about the relation between PS and GIMP USM settings. Myself, I usally set radius 10 , amount 0.5 and threshold to 4 and play with the values around those defaults a bit until I am happy, but it would be interesting to see if someone actually knew the relation between PS and GIMP USM.
I will search for USM PS and GIMP using Lycos and Altavista to find a few more links.

(I found this as a one link about it as well http://www.cambridgeincolour.com/forums/thread2386.htm )

Sven,
Yes I haven't found any direct conversions yet, but in the meantime here is a page that is a great article in that the guy compares how to use USM in Gimp, Photoshop, and ImageMagick, which I only came across lately via Linux and mobile development research I was doing:

http://redskiesatnight.com/2005/04/06/sharpening-using-image-magick/

That's a good one. I was going to write to him and ask him something about his site, but I'll also ask about the usm conversion.

I have never used/seen Photoshop so don't know the ratios between PS and GIMP USM.

What are the ranges for Photoshop ie Gimp's are Radius 0.1-120
Amount 0-10.00
Threshold 0-255

Once we have this then we can convert the PS settings and see if they look the same in Gimp.

You can if the numbers refer to the same scale, but you do not know how the numbers are scaled/weighted.

That's a good one. I was going to write to him and ask him something about his site, but I'll also ask about the usm conversion.

There is a table in the article referenced above which suggests that radius and threshold are the same in Gimp and Photoshop and that amount in Gimp is one hundredth of that in Photoshop.

Norman

Yes, this information was good. It do as Norman points out make a suggestion of relations. I think it seems valid so I am happy with it. Thanks.
