Hi everybody

I am working on a project and would like to use the method where there is only one color in the print and the rest is black & white.

Could anyone direct me to a tutorial or a past thread that explains this? I couldn't seem to find anything when i was looking through past forum posts.

Thanks

Rick

Hey Rick I was wondering the same thing. I tried desaturate....no cigar. I tried channels....ditto. I tried color ballance. The winning entry last week is a good example Licorice L'Amore. Maybe dsidwell can give us a tutorial :)

Theres already a tutorial about it on the site:

Here

Its kind've the opposite to what you want but the same applies.

For it to be DPC Legal you'll have to desaturate the individual colors across the whole picture, but if you're just making a picture that's not for DPC. I would suggest using the selection tool and then desaturating the different colors. This way you can desaturate ALL the color out of The parts you don't want color, and not just specific colors. You can see in Licorice L'Amore that there's tiny bits of red left on their earlobes and his nose. That could have been avoided by using the selection tool, BUT that'd be illegal for a DPC entry.

In Photoshop you go to image / adjust / hue and saturation. Then you use the drop down menu to select the color you want to desaturate, then just drag the saturation bar all the way to the left. This is really useful in post image processing for dpc entries. You can get those colors looking their best.

The trickiest part, after desaturating all of the colors, is that human skin has so many colors in it. This is why when you look at Licorice L'Amore, you can see red on the nose and ear of the guy, so I found that you need LOTS of light. Notice how the shirt of the woman in the photo is just a tad over exposed? That's part of the price you pay.

I used a regular 150 Watt incandescent bulb on this couple and it was very close to them--just out of the frame. This did two things: first, it made their skin both brighter and more "yellow," which is important. Second, and unexpectedly, it really enhanced the red hues of the licorice to almost cartoon colors, so I was lucky, as you'll see.

When I began using Photoshop, I first used levels and curves to brighten the faces of this lovely couple even more. The biggest challenge here was that the man was so much more tan than the woman; curves solved this problem pretty well. Brightening their faces also washed out a lof of the color, too. It also overexposed her shirt. When I finally desaturated all of the colors but red, there was still lots of red on their faces and arms, but my wife reminded me that the licorice was TOO red and cartoony. So that fixed my problem: I simply desaturated the red by about 35 percent. Viola!

Hey everyone!

My area of expertise is rock photography. This is a photograph I did for a client that might fit the mold of what you are looking for. What I did was take a color photo I shot at one of their shows and use the desaturation brush to turn the colored areas into black and white. It took about 10 seconds to do, very easy. I used Paint Shop Pro to edit this picture, but I think photoshop and Painter have almost the same tool.

Hope this helps! It is just a different method of this technique.

hmm for some reason the photo I attached is ALOT smaller than the original, and looks awful. Here is the link to the original if anyone is interested:

My favourite method if the coloured part is small is to create a colour layer and fill it with black to make it b/w. Then I make a layer mask for the colour layer and mask out the coloured areas with varying brush sizes.

Thanks very much! I've been dying to figure this out and your method is the first on I tried that really worked for me.
Here is my first attempt with the technique.

Shari, Are you sure that is your first attempt? it looks great!!! I'm glad this method worked for you! I find it to be the easiest (and fastest) way to do it! Congrats on the nice image.

Wes, bless your heart! You've explained it so well I can finally follow the directions. Thanks!

I do mine differently. This isn't DPC legal but it's great for prints or whatever.

example checkers photo

I make a b/w or toned copy of the color photo. Layer the b/w copy over the color photo. Using the eraser tool, in this case at about 30 % or less, I erase over the area I want color to show through. I then merge the layers and save with a new file name.

I do this exactly like this...
Although, if you have some tones of this color in your picture that you want to get rid of, you simply copy that part to a new layer and deaturate the master in "Hue and Saturation"

here is my thing: Perspective in Orange - The guy who is sitting is also wearing a orange clothes, I copyed him into a new layer etc.etc.

i've done quite a few images
leaving the subject color, and the rest of the image BW
what i found works well is to use the magic wand/ marquee tool
to select the area you want to leave color. carefully (zoom in)
I then COPY to a new image ( transparent ). convert the original to grayscale
then back to RGB color. drag the new image into the original and carefully align it.
here is an an example done in that manner

Thanks for finally teaching me how to do this w/o using a filter (I find they're hard to control)!



Would have fit in nicely for desolation ;)

It depends on how they're achieving the effect. If for good reason you think something is done illegally, hit 'DQ' but don't let it affect the score you give it.

I used one b&w image to create this photo:

two-coloured photo

Converted image to RGB, duplicated the original background layer, then through the hue and saturation command in Photoshop I colourized both layers with different colour. Then erased portions of the top layer to reveal different colour underneath.

This is DPC illegal for submissions, but if you want to create images for your portfolio, you can do just about anything that hits your mind.

Here's one that I took last weekend. It was kind of boring in full color or full b&w. I like it this way. I still haven't gotten too comfortable with layers, so I actually just selected the door, inverted the selection and then desaturated. Also covered up two white notices on the door.

Thanks everybody for sharing your comments. My first go at the technique: Discipline

OK, the technique that I use to achieve this look is to go into my photosuite 4 program, I choose colorize, and make the whole picture black and white, then I go back and use the eraser tool to change the parts I want color back to color.

My question is, is this technique legal for the dpc challenges?

Well i got dq´d for that kind of editing so i assume that is not legal
 09/05/2003 04:41:07 PM · #25
no, that method is not legal because your picking the spots to recolor- not editing the image as a whole. Desaturation (entirely) works- leaving the chosen colors behind.
