Wavelength, in order or your image to be legal in basic, you just need to use adjustment layers instead of pixel layers. But you'll have the same result as if you had chosen the blend of the two distinct colours. I.e. your method with blue and yellow will result in green.

Monotone/Duotone/Tritone/Quadtone wouldda' been easier.

OKAY, here's a rough-and-ready, no aesthetic frills exploration of options:

Original image:



Grayscale mode conversion in photoshop, followed by a ps duotone of the grayscale conversion:



Red channel B/W conversion in photoshop followed by a PS duotone (of the red channel conversion then switched to grayscale mode) and a selective color duotone of the red channel conversion (made by adjusting the colors of white, neutral and black channels):



Note that the red-channel conversion is far superior to the straight grayscale conversion as far as tonal range. Note also that different base colors for the duotones have been used. Note also that these are all "warm" duotones, but you can use any color basis that suits your sense of where the image needs to go.

For whatever this is worth; they are not perfected images, but they are all basic-legal.

Robert, could you give a real quick "how to" of this step... I'm totally lost! ps. When you have the time.

Thanks

To make a B/W image using color channels in Photoshop:

1. Open color image
2. In Layers pallette, click "channels" tab at top and view each channel indvidually by turning the others off. Decide which of the three channels (R, G, or B) is closest to your desired result.
3. Go to image/adjustments/channel mixer
4. Check "monochrome" box lower left
5. Be sure "output channel" at top is "gray"
6. Play with the sliders to adjust the relative inputs of the red, green and blue channels

As a rule of thumb, the TOTAL percentages should be 100%. An all-red-channel conversion, which is what I used on this image, is 100% red and 0% green and blue. Sometimes one of the other channels is the best one, sometimes a mix of all 3 gives the best results, or 2 of the 3. You might have 80% red, 20% blue, 0% green, whatever.

This is your B/W conversion. If you want to use Photoshop's "duotone" mode, you will need to to take this red-channel conversion and...

1. Go to image/mode and select "grayscale".
2. Click OK when it asks about discarding color information.
3. Go to image/mode and select duotone.
4. click each of the color swatches in turn and select the base colors for your duotone: in this case, it was black and a warmish brown color. It could be anything.

In both scenarios, the converted images can be further adjusted with levels, curves, brightness/contrast before or after duotoning, although in this case I just blitzed through and did no adjusting, only converting.

Hope this helps...

Robt.

Rob't, Those are both very good descriptions. However, Photoshop Elements cannot perform either as far as I can see.

Sure. It's possible to create a greyscale image in PSE...but not duotone. (Basic editing rules.) This is because PSE doesn't handle "Channels" in the same way other versions do. Nor does it have a "duotone" image mode.

I'm working on figuring it out. I'm sure there's some sort of work-around. It just seems unfairly biased to people with more advanced software....and people who don't bother much with these forum posts.

Edit to add a quote from the help file: "A two-color grayscale file that uses two custom inks. Photoshop Elements does not support duotone files."

There IS a workaround, it's in my illustrated post. Make the best grayscale conversion you can and use "selective color" in the white, neutral, and black channels to "tone" the result. The poster I was answering with this dteailed workflow was asking specifically that I expand on how to do a "red channel" conversion.

Wow, THANK YOU FOR A QUICK RESPONSE!! That was the step I was missing (the layers pallett!).

I think I've got it now!!

Thanks,
Roland

Oh well. Guess I'll sit this one out, too.

I retract that statement. I think I found the work-around for Elements. I don't have time to write it up just now....but I will this evening.

In brief, enhance > adjust color > remove color. Then, Hue/Sat, check the "colorize" box. Use the hue slider to shift the color to a tone you like.

And this is what the help file says:
To colorize a grayscale image or create a duotone effect:

1. If you are colorizing a grayscale image, choose Image > Mode > RGB to convert the image to RGB.
2. Open the Hue/Saturation dialog box.
3. Select Colorize. If the foreground color isn't black or white, Photoshop Elements converts the image to the hue of the current foreground color. The lightness value of each pixel does not change.
4. Use the Hue slider to select a new color if desired. Use the Saturation and Lightness sliders to adjust the saturation and lightness of the pixels.
5. Click OK.

Having challenges like "Duotone III" that triggers discussions like this is great. It acts as a catalyst for new learning. It brings out the best of what this site is all about, learning photography.

Duotones originated as a strictly "post processing" technique which drills to the core of current site discussions.
 02/15/2006 03:57:46 PM · #65
Like others, I just don't get this "Your submission should only consist of two tones (black/white, sepia, etc)" since neither black/white or sepia tone are duotones! Also there were very few duotones in the first Duotone challenge.

So does one dare actually enter a duotone image in this contest? By selecting two diffent colors (instead of one color and black) and adjusting the curve on which they are applied, some very striking pictures can be created. But will the unwashed voters say "what the heck is this -- 1"?

Here's your chance to educate them. : )

I say enter a B&W or monotone or duotone or whatever ... I think anything which looks like it was made with a restricted color pallette will be fine. Enter something you like, and don't worry too much about the score -- if it looks like a duotone to you, most other people will probably think so too.

This is a tri-tone:

Brent: Duotone legality in PSP.
Which means, if I meet the challenge, I'll be DQed.

i read this but does anyone know how to go about the doutones commands if you're using Macromedia Fireworks?
 02/15/2006 07:03:25 PM · #68
Ok I am going out on a limb on this so no one shoot me (Mr VP??? where are you????)

I use Express Digital Darkroom for my portrait work.
That too has a one click duotone function (although limited to only a few combinations)

Would that application be legal ???

02/15/2006 07:20:00 PM · #69
I think I understand what a Duotone is. And I am using PSP X and its not as easy as PS to edit certian things. So I wanted to do a little test. I select an image and their is an option to count how many different colors their are. It came back with 41,000+. I switched it to greyscale their were 198. I then just used the colorize feature and checked the color count...198. It just tinted the same 198 fromt he greyscale to that color. I am not sure if this is a dutone or not but its about as close as I can get.
 02/15/2006 07:23:56 PM · #70
Just a little follow up....I used R/G/B levels after greyscale and same color number count 198. I then used Shadow/Midtone.Highlight adjustment and it dropped to 195. I used USMN and it jumped to 7,900. Not that the amount of colors counts. Because I am sure the colors are all from the same family.

For those PSP users, here's something to consider....

//www.xero-graphics.co.uk/set3/duochrome.htm

free plugin. You can choose which color will be toned for highlights, and which color will be toned for shadows, strength of effect, etc..

I had better luck when converting to BW/grayscale (choose your method, just make sure if you use channel mixer that you flatten to single layer first). Tweak around with the sliders and see what you can come up with.

Not exactly sure if it's legal, because it could be considered an 'effects' filter (a no no under basic). But, at the same time, it's simply a dialog box like I'm sure PS has, and produces the same type 'effect' as choosing your colors when converting to duotone mode in PS...and it doesn't visibly create any layers. I would consider converting to duotone an effect in any case, no matter what app you use to do it or what menu it falls under.

So, if you're feeling adventurous, and not going with grayscale or sepia...

That ought to stir the pot a bit. :-)

PSP User.
After looking at that example. I think i will stick with B @ W or sepia. :)
 02/15/2006 09:33:54 PM · #73
Yeah, you'd think they would post a more appealing example. But, you can choose better colors and decrease the strength. It *can* be nice...but as with any tool...can be used for evil as well. :-)

I just went to dictionary.com for the definition of "duotone". It reads "Any picture printed in two shades of the SAME color."
 02/15/2006 11:08:05 PM · #75
i see this thread is still bubbling along. has anyone come up with definitive answers to the following 2 questions:

1. are b/w or sepia actually duotones or will submitting them just get me a bunch of DNMCs?

2. if b/w and sepia are not duotones, can i legally produce a duotone with pspx?
