Photoshop Conversion to Black and White

 

The great thing about Photoshop is there are almost always several ways to accomplish the same result.

The bad thing about Photoshop is we often get confused with all the different ways there are to accomplish the same result.

One technique that often makes good pictures better is turning your digital colored photos into Black & White images.

"Why do that," you ask?

Sometimes, the many different colors or patterns in a photo distract from the overall appearance. Or, sometimes you want to feature only one particular aspect of a scene  - and that can be done with selective color. That's accomplished when you turn the original image to black & white and then allow only your chosen feature(s) to be in color.

Here is a reminder of the most popular ways to turn a colored image to black & white:

Image - Adjustments - Desaturate

Image - Adjustments - Gradient Map (preferred for preserving details) be sure palette set to default B/W

Image - Mode - Grayscale

Image - Adjustments - Threshold (absolute black or white, no grayscale here)

Layer - New Adjustment Layer - Hue/Saturation (move saturation slider max. left) good for selective color by later using layer mask to bring areas back to color

and for the more artistic look...

Filter - Sketch - Chrome

Filter - Sketch - Conte Crayon

Filter - Sketch - Graphic Pen

Filter - Sketch - Halftone Pattern

So next time you've feel the need to go Black and White, plan a few extra moments to try out something new.

Photos to Sketch Drawing

After posting the previous lesson on converting color photos to pencil line art, many of you wrote asking for something better suited to portraits.

Your wish is my command!

Here is the simplest method I have ever found:

Duplicate your image using keyboard shortcut Ctrl-J
or you could also use Layer - New - Layer via copy

Next, desaturate (turn to B/W) the new Layer 1 using
Image - Adjustments - Desaturate

Duplicate Layer 1

On the new Layer 2 go to:
Image - Adjustments - Invert
now your photo should look like a negative

Now change the Blend Mode to Color Dodge
Whoops! Your photo just went all white...
well, that's all right.

We're going to now use the magic to give new life
to your photo...it will now be re-born in sketch form.

Ready?

Apply Filter - Blur - Gaussian Blur

BINGO! The magic sketch appears.
Now wasn't that simple and fun?

For best results, move your slider full left then bring back up until you get the best effect. You can also experiment using motion blur or radial blur in place of gaussian.

Finish up, if need be, by getting rid of any stray looking areas. To get the job done use the eraser tool, paint over with a white brush, or use a layer mask technique, whichever you prefer.

Remember, there's nothing like having all these tips right at your fingertips.
