Larry, I really like your rendition but it looks like you're advancing from my post D-Caboose. If so, and so as not to add confusion, you should perhaps work and post from the original file so as everyone has a consistant starting and end point.

Cheers

Dave

Dave, you're right. Grabbed the wrong image. Here is one corrected from the original by the same process.

Well I have been learning how to use channels a bit by what has been going on in the forum. I used your instructions Flora. For some reason the hue and sat was greyed out , but when using the other function you mentioned this is what I came up with . a little different coloring than yours . I am using CS2 and my box looked a little different than yours. Neb

I think the correct color is the original post. Both the shadows and middle grey are very well balanced. The question is How do you make the image more personally appealing ie Colors you would see on a cloudy day. I noticed on a number of corrections, including mine, that had unusually high amounts of red in the shadows, the result of global corrections. Perhaps color changes should be thru masks on selected areas.

Hi everybody,

Ken,

sorry for getting back so late but I've been very, very busy (and will be for a while still....)

CJ pointed you in the right direction ... (thanks CJ!!!)

The first tutorial I read about using Apply Image (small brother of Calculations) is here.
.. and, after starting to understand what could be done with it, I started 'experimenting' with it while dealing with different problems ....

I use it regularly and it hasn't let me down yet ....

Hi Neb,

what might have happened is that you were still working on the Red Channel only ... (Attachment1)

Make sure that before giong back to the Layers and opening the Hue&Saturation dialog box, you have activated all three RGB channels again .... (Attachment2)

P.S. I'm also using CS2 .... In your 'Apply Image' Box did you tick/Check the 'Mask' box under the Opacity Option?
