Conversion from Color to B&W tritone

Text and images by Matt Brandon - All rights reserved.

A few people have commented on a technique that I have used in my B&W conversion of Raw images. I have two confessions to make here. First, is it is not B&W. It is Tritone, a type of grayscale conversion found in PhotoShop. The second confession is I am still new to it. So, if you read this and have a better method, I am open to hear about it. I will say that what I am doing here seems to be working.

I learned this technique from a photographer friend I met on the net, Mitchell Kanashkevich. This guy has some fantastic images of India. You should check them out.

I am on a Mac, so all this applies to Photoshop CS2 for the Mac. I think most of this should be applicable to a Windows version of Photoshop and Elements. OK, so lets make a Tritone image:

First open your image, either in RAW or JPG. Go through your normal workflow. Make all your layer adjustments, levels, curves, and any other adjustments you feel you need to do to tweak and balance the image. Now flatten the image.

Now go back up to the menu and this time select Image>Mode>Duotone.

Next, go to Image>Mode>Grayscale in the Menu. This will give you an unremarkable B&W image. Not much to look at, but unbelievably many people stop here and claim this as their finished B&W image. Not us, let’s go on. Now go back up to the menu and this time select Image>Mode>Duotone.

This will bring up the Duotone options. Under the Type pull-down menu, select Tritone. Now you are given three options of ink to use. Here is where you can get creative. You can use the inks I am going to suggest in the next paragraph or use the preloaded inks under the Load button. If you click the dialog’s Load button you will be taken to the Presets folder. The Presets folder contains all kinds of fun stuff, but we are concerned just with the next folder called Duotone. Select the Duotone folder then the Tritone folder. Once in here you will be give a choice of three more folders; Gray Tritones, PANTONE® Tritones and Process Tritones. Open any one of these folders and select any of the choices. If you don’t like what you get, try another one. If you don’t like any of them try my combination below.

What Mitch and I use for the most part is Ink 1: Black; Ink 2: PANTONE 1205 C; Ink 3: FOCOLTONE 5012. Select between Pantone, Focoltone and other inks by clicking on the square ink sample in the dialog box. Once you have three inks you like loaded, press ok.

At this point the lovely balanced image you had before is lost and the image looks pretty dark. Have no fear.

Now go to Image>Mode>RGB to switch the mode back to RGB. Now go back to your Levels adjusment and crank up those highlights and mid-tones to a level you like. What I often do now is make a adjustment level for Selective Color. I then select the blacks from the pull down menu. I then boost the black level of the black color choice up 10 to 15%. This gives me some richer blacks and a nice contrast level.

And there you have it! Now just go back to your normal work flow for any last minute tweaks and sharpening.

I hope this helps and gives you a “B&W” image of which you can be proud!
