Unsharp Mask Demystified
Thursday September 9, 2004
by Ellen Anon

"Ask any number of digital photographers the settings they use in Photoshop’s Unsharp Mask filter (USM) to sharpen their images and that’s the number of different responses you are likely to get. Because of this a significant number of people turn to plug-ins to do their sharpening for them. However once you understand the basic principles involved in using the USM it is fairly easy to make it work predictably and effectively."

ImagePrint 6 Notes
Thursday September 2, 2004
by Mitch Alland

I am pleased to see that the new ImagePrint manual for v6 is a great improvement over earlier versions and is, in fact, excellent. The extensive Troubleshooting Guide section is a good addition. Also, as program installation has been simplified, I believe that most questions on IP problems that come up on online forums can now be answered by suggesting, in the best Unix tradition, that the user "look it up in the manual...." These notes are based on ImagePrint 6 build 1.08. If you are using a later build some of the issues and glitches discussed below may have been fixed, as ColorByte is aware of all of them.

This is a follow on from my Black Point Comp question since I have new info which has confused me a bit.

I was given a profile from Ilfochrome out of a Lambda and the operator told me to soft-proof the file with Preserve Colour Numbers ON. This did not make sense until I found out that the RIP driving the Lambda is not ICC savvy and by checking the PCN box I will see what my master file will actually print like. Basically I am supposed to tweak the file using this preview until I am happy and then I will get a decent printout.

It seems to me that the profile should contain all the info I need to change the numbers, in this case, a much more saturated file is needed.

So, if I 'convert' my ProPhotoRGB file to this profile I will essentially be moving my data from a working space into a device space. PS will display this using the monitor profile as normal but the actual numbers will have changed to reflect the characteristic of the output device. Thus I will still see a normal image on the monitor rather than a visually super saturated one. The output should match this more or less.

Is my logic here correct?

The method suggested by the lab seems very clumsy. They said the profile is simply a tool to allow manual tweaking of the file to when I want it. The profile was built with an Eye One so should be fairly accurate - except there seems to be no Paper White/Ink Black data in it.

Any comments would be appreciated.
