For KR1156's image start out with these in Calculations:
Source 1 Red
Source 2 Blue
Blending Add
Opacity: 30 offset:-244 Scale: 1.03

Then use apply image to clean up and a brush to remove the rim of the glass.

For JMB's image that he put up:
Start with Calculations
Source 1 R inverted
Source 2 B

Blend Add

Opacity 100 Offset: -174 Scale: 1.021

Mask

Grey

Then use apply image to clean up. Might be some density at the top of the spray though.

Some really nice tip, Chris. Definitely a great technique to add to my arsenal. The farthest thing I've gone with Calculations is b+w conversion. How are you determined which channel to blend? I've always wanted go get Katrin Eismann Masking and Compositing book. Are you involved with that book as well?

Another good way to select water is to use the force colour in PS extract tool. I remember seeing a great tutorial on this by Ben Wilmore in his Masking CD Tut.

Only as a consultant. In her first and second book on retouching and restoration she has some of my calculations stuff in there.

Channel Chops is considered the best book on calculations, but good luck trying to find a copy....i've heard that it can sell for over $400 on ebay as it is out of print, and Bert Monroy said there are no plans for a reprint or version 2 of the book, at least not on his end...

Channel Chops is a great book. Clutching my autographed copy very tightly.
I actually wanted to write a follow up to that book about 7 years ago but my publisher said there wasn't any market for it. Even talked to Katrin about it before her masking book came out. She thought it was about time a masking book came out again but we never got around to heavy duty calculations work. Maybe my publisher will listen now? Who knows. Market dictates.

Re: Water Dress (AMAZING work!) - Possibly NSFW - parcial nudity

those calculations worked nicely chris, thanks for that. Would like to experiment with it a little more next week when i have time.

i've never used the offset and scale portion before though, i will have to do some reading on this...I would like to be able to use calculations with more of a knowing on what moves to make before hand, ratehr than experimenting, would save a bit of time.

Pretty much any kind of color cast, tonal corrections can be done with calculations as well as masking. Adding detail from one channel to another, completely rebuilding a channel from two other ones, or three other ones can be done. Making black and white images. Sepia tones.

There really isn't a book out there for this. THe Photoshop Bible I think touches upon it slightly. It has been awhile since I have read it.
Chops is a older book that goes into calculations blending, but it does it more from a special effects approach than from an image approach. But you can get an idea of how it works. Search around the internet for Kais tips. He goes into it pretty well also.

I believe that katrins masking might also have some calculations work in it, at least for blending channels not sure.

If you do a search for my name and PEI on the internet you might find a article about automatic masking that I wrote for them. That was at least 7 years ago so it might not be around still. But calculations hasn't changed. Ever. Sadly.

Chris,

For the directionally challenged (such as myself), can you explain the water extraction process a little more clearer. I printed your directions and followed them until I got to the bottom of the Calculations dialog box where it says Results. It gives you three choices: New Document, New Channel, Selection. What do I do here?

Bella

You can do whichever one you like.
I prefer the new channel option so that i can modify it if needed.
The New document is ok if you are going to save it with some other masks for later use.
I rarely if ever use selection. Its to easy to accidently deselect and not notice until its to late.

So save as New Channel and load the channel as a selection etc.

Chris
