Sorry for the delay. Getting ready to leave town for a few days, and the girlies aren't very considerate.

One of the better ways is like this:

3. Ad-Layer > HSB and bring Sat all the way down
2. Ad-Layer > Curves and manually tweak contrast in each seperate channel
1. Colour photograph

It is an absolutely wonderful technique. Does wonders for converting fleshtones. If you are not in the mood for Ad-Layer Curves, feel free to try Ad-Layer Brightness/Contrast or something else. Personally, I prefer Curves.

Remember: you can paint on the Ad-Layer. Let's say you have some sky and a building. Well, pumping up the contrast on the clouds destroys the building; and pumping up the contrast on the building destroys the clouds. Just paint!

4. Ad-Layer > HSB with Sat all the way down
3. Ad-Layer > Curves with clouds manually tweaked and painted in
2. Ad-Layer > Curves with building manually tweaked and painted in (basically an inverse of #3)
1. Colour photograph of some sky and a building

Excellant technique to play with.

Gotta go!

Stroker, when you're back, can you explain in further detail how you do this? [confused]

Go off now, get away and enjoy your break!

Wendy, the 2nd half of Introduction to the Curves Command, Page 2 talks about this.

Add your Curves Ad-Layer.
Using the drop-down, go to Red and tweak
Go to Green and tweak
Go to Blue and tweak
Go to RGB and tweak one last time.

Ah yes, thanks for the 'refresher', Stroker! [righton] That's a fabulous tutorial and one that I went through months ago. It seems that I forget more than I learn these days if I'm not putting it into regular practice! [innocent]

Hi Blake,

I'm not familure with the use of such filters for black & white so I went to a page where a fellow uses them.

After seeing wht you are talking about at least I think this is, I would suggest this.

Find a photo with the filter(s) applied that you want and open it in photoshop. Then take your eye dropper and sample that color to see what the RGB setting is.

Here is a link to the page I looked at and I must say I never knew this type of photography exsisted.

I don't know if this helps or not but I gave it a try. 8)

Hi Blake,

I think this is what you are trying to achieve?



Curves will give this effect too. [righton]

Hi Blake,

I did some goofing.

I tried the method I mentioned but I didn't use the channel mixer I used the Curves tool.

I sampled the image above that shows the example of the filter.
When I sampled the filter I got the RGB settings from that.
Then I went into the Curves settings and applied
the numbers to the corrosponding colors.
I placed the numbers in the OUTSOURCE not IN!


R = 210
G = 31
B = 52

This is your original picture.





This is your image with the RGB settings.



I don't know if this is how it's supposed to look or not like I have mentioned I havenever used filters so I'm just guessing.

Hope this might have helped in some way. [righton]

Always something to learn around here!
