Chris,

It is always amazing...... you are right, every time you teach, something new crops up.  But, that's how we learn!  You might check to see if the color settings in Photoshop have all those little check marks checked that warn you of mismatches in color profiles.  Students often get sRGB files off of digital cameras and forget to convert—especially if Photoshop is not warning them.  Also, I had a combination of either CS2 or CS3 and one of the Mac operating systems for a while magically change my color space in Photoshop from Adobe 1998 to sRGB.  I never figured out what caused it, but one of the upgrades "fixed" the problem.

You should post the results from the inverted color file negatives!

John,
Thanks for the thanks and glad you got it solved. 

I am going through the diginegs part of my alt class at the moment, and figured with the amount of times I have taught this I probably have encountered every problem in the book. Now, I am not Dan Burkholder (can't imagine the snafus he has seen in all his years teaching) but just when you figure you'd seen it all, something else crops up. 

So today, what happened for the first time that I noticed, is when the students were bringing their images from one lab to another, the printing lab computer was switching the files from Adobe 1998 back to sRGB "on the fly" so to speak. So they thought that they had that part of the problem licked, and it wasn't.

THEN two students printed out negs for BW printing and forgot to desaturate/remove the color of the original image, so they got these wild red negs with magenta trees and whatnot, very cool. It was late, I had them print them that way anyway, and wouldn't ya know, the print was cool! 

And then I learn so many things from them, like the "expand view" on the drop down menu to make the curves palette bigger, and the window/arrange/float all in windows in case you lose your top of your image and can't drag it down from underneath the control bar in CS4...sharing tips like this is such a good give and take between student and faculty and I end up learning more than they do I think.

There's just not enough time in the day to learn everything Photoshop has to offer.

This week is calibration of BW and next we start cyanotype. Starting out with BW is always quickest and very easy to spot mistakes when they occur.
