The doc's say that there is a bug in the K channel for the masks.  I used the L channel and then brushed a little to fix it in CS5.

I run into problems with the CMYK in CS 5.  Mike says it is feature, but my results look different than the video.  Even if I can see wg CMYK, I do not get the maximum black option in masks.

Is there a version that I should be running for these examples?

BTW- CM has a skin mask.  Sky mask?

Are you taking the image into CM as is or are you converting to CMYK first?  If you convert the image CM is going to use your CMYK settings from Photoshop.  If you just take the image into CM and select CMYK what do you get??

Mine is working just fine for CS4 but I ahve no way of testing CS5...let's see what your process is first...

I think Mike is looking at allowing you to define the mask in more general terms...Or even allowing you to select the color for the mask.  If you have CS5 you can define the mask and CM will respect your choice.

Unfortunately, this issue is sporadic. 

I just opened a jpeg in CS5 went to CM.  And everything was fine.  wgCMYK was an option.  It allowed no  black, to max black on the gcr.  Cool.

Sometimes,  (grrrr...) I do the same thing, no cmyk at all.  If I use the K mask, no GCR options.  If I convert to cmyk, then I get cmyk options, but no gcr (photoshop apparently does not change gcr, only through different profiles).  I then convert the image back to RGB or LAB and wgcmyk works but no gcr options. 

I have two computers, both running win 7.  One is 32 bit and the other 64 bit.  For these classes, I only use the 32 bit photoshop.

I will muddle along until I break it or see the real pattern. 

It is working now (for today).

First, fix the image without concern for the sky. 

Second, mask the sky, and fix it.

Save the mask, load it in Photoshop and paintbrush the mask to fix.

In general, should you mask an area out, fix that area.  then invert the mask and fix the other area?

Steve,
Your work flow question comes down to how you want to work...
I know I sometimes add and throw away layers like they are not even there...

Which is best??  hmmm My way??  Kidding...I think it comes down to the goals.  If you know you are going to have to flip the mask over as you have described then I would create a holding place for the mask.  Layer...with Mask.  You can always paint on the mask so long as you do not flatten the layers.

Personally, I tend to work in iterative steps.  I get the image to a safe place and save...then move on...You can also use selections as a part of this instead of a mask.  Just like we did on the portraits page where you had to fix all of the separate images with a selection box...It is up to you as for what works best.  I try to be as creative and simple as I can be...It keeps it repeatable and easy to use...

Your image looks pretty good overall but it is too over saturated...Take it into lab and desaturate it a bit and see if the blues and reds are less neon...

Oops.  (I am getting tired of saying oops). 

The image I posted was with the sky boost but I disabled the mask.

This image is with an inverted mask and corrections made to the foreground.  IOW, I masked revealing the sky and fixed the sky.  Then masked the sky

Steve,
You have the saturation in a much better place..but thee seems to be a greenish yellow cast over the entire image...more blue than green.

Hmm...  I place a neutral.  It looks a little better.

You are chasing this one around a bit but this is much better...
Visually, the road in the background looks a bit too red...Maybe try adding a touch of yellow to that range of the image and see if overall it gets better...

It could just be a subjective color issue but see what you think.
