Introduction
Mary Sue works in Accounting. She dropped off an old photo of her uncle Albert washing a car. The photo is in good shape, there are no artifacts, and Mary wants to be able to show a color version to all her friends: Her picture is black and white, at present. She came to see if Liam’s team can help.

Colorizing

Liam has just completed a meeting with Mary Sue. Together, they discussed what the overall theme of the site should be. Oneof the user groups will be an internal intranet, meaning its use would be limited to MMC employees.There will be a segment that appeals to the employees. Currently they see a need for two sections: Vacations and Hobbies. They will ask employees to submit photos relating to those two sections. A few photos have already come in. Three days have passed, and Liamhas flagged the best within each section. Let’s look at those photos.

At the conclusion of the chapter, you will be able to:

  • Color black and white photos
  • Change colors for an existing photo

Here is where Liam created a folder structure; you do the same now.. Create a child folder of NewMedia named Apps. Inside Apps create a Photoshop folder. Then add Chapter 4. Follow Chapter 4 with anImages folder.Figure 4.1 illustrates the folders configuration.

Figure 4.1:The folder configurations

We will start with what you see in Figure 4.2 and with the content you can see in Figure 4.3

Figure 4.2:The starting picture

Figure 4.3. The revised photo

Find the assetsandopen them.

They are: car.jpg, kitten.tiff and farm.bmp. They should be in your Chapter 4>Images folder.

Photoshop provides many ways to arrange assets. Figure 4.4 shows one such alternative.

Figure 4.4. Our starting workspace.

A little review.

(1)Which graphics formats can we use for displaying photographs on a Web page?

(2)Whichgraphicsmodes does Photoshop support when creating a new document containing a background?

(3)What other workspace can we use to show the arrangement of the three photographs?

Checking for RGB

When you listed the graphics modes, we hope you replied one was RGB; that’s the format we want for now.

Select one image at a time and, if necessary, change its mode to RGB: Only Farm should need to be adjusted via a Menu selection:

Image>Mode >RGB:

Note: Index mode commonly used for print, limits you to 256 colors. See the Appendix 2 for more information on indexes.

Note: Here is a common approach for selecting items: Select their background, and then choose the inverse. Backgrounds are often easier to select, as is the casehere with kitten.

Resize the kitty.

Q: Do you remember the menu item that will tell you the size of an image? And is also used to resize images?

  • Resize to 150 pixels wide

Figure 4.4. The panel to view and modify photos

Kitten’s background is all white, so it should be easy for us to use the Magic Wandto select the background and then use Select> Inverse.

Your turn:

Select the kitten’s background using theMagic wand:

  • Click with the Magic Wand in any white area:
Figure 4.5. SELECTING A background

This process selects the background;However,we want all but the background:

To do so, choose:Select> Inverse

Here is the result.

Drag the kittenyou just selected onto the car in its lower left corner:

The next figure shows the updated layers

Adding a new Background

Using a Layer maskMary Sue has a question She wants to know what a layer mask is..Liam explains” Imagine a Halloween mask that covers part of your face. Someone accidentally sprays a blue paint. What happens when the mask is removed?”.

We want to mask out trees and sky.

Place the complete Background (squash) image under the car layer

  • Basically Use the brush to mask out the background (sky, trees etc), exposing the farm under the car..

Switch to the Squash document

Select all (Ctrl-A)

Edit>Copy (tCrl-C)

Switch to the car layer

Edit>Paste (Ctrl-V) onto theCar document (Ctrl-V)…you can’t see the car anymore!

Here is the updated Layer panel.

Figure 4.7. An updated Layer panel.

When you paste into a layer, a new layer is created (Layer 1, in our case)

Rename the layer asBarn:

Figure 4.8. Update Layer 1

Lock the Barn layer (why?)

YourBarnlayer might be incorrectly poisoned above the car layer. Think what we’re going to do:There will be a car layer on top of abarn layer. We will then erase portions of the car, exposing the underneath barn scene.

Figure 4.9. An incorrect layers order

Oops, we actually need the opposite of what we have

Pull the Barn layer down (Drag the word) so it’s underneath the Car layer. You can see this in Figure 4.10

Figure 4.10. A correct layer sequence.

As stated earlier, we will mask out what’s not needed on the Car layer, ineffect, erasing what we do not want . The red arrows below show what we will mask out:

Figure 4.11. Establishing what to mask.

To do what we want to do: Use a Layer mask.

Choose the car layer

Observe the bottom of the Layer panel: find the Add Layer Mask button/icon

Figure 4.12. Add the Layer mask.

Choose to apply a mask;Click it

An empty white box appears on the Car layer’s mask…white hides nothing, so nothing is masked now.

We will “paint” with black “paint”. Where we paint (in black )will be erased and a mask that hides is created.

Click the white box.

Make sure the Foreground color is black. i.e .Press D (default)

Figure 4.13. Verifying the Foreground is black.

Press “D” for default

If necessary, reverse the FG/BG so Black is on top

Figure 4.14. Making sure the Black color is selected

Click on the Brush tool:

Figure 4.15 Selecting the brush tool

Set brush size around 50px, and 24% Hard,

Mode to Normal

Note: don’t be reluctant to experiment with these properties.

Figure 4.16 Initial mask properties

If you select too much, reverse black and white colors and paint in white

Let’s add some orange color so it looks like dawn or dusk; oranges and yellows are said to be warm colors, blues are considered cool. We will add a new layer on the top of the stack so it affects everything below it:

Select the carthumbnaillayer (NOT the mask)

Apply a photo Filter

Note:In pre digital days, if we wanted to apply an effect to our photos we had to screw glass filters on the front of the lenses. A very popular filter was an 85, called a warming filter….Today, all is digital.

Choose Window>Adjustments The Adjustments panel opens, as seen in Figure 4.18

Figure 4.18. The Adjustment panel opens.

Choose photo filter:

This New Layer window pops up, Name it Warmas we did figure 4.19

Figure 4.19. Prepping for the warm filter

Look for this panel which pops up when you click OK

Choose warming filter (85) and increase the density ( maybe 65%)

  • Save as BlackAndWhiteV5.psd

Suppose don’t want cat to have the sepia color…just move its layer above the filter layer

Now: Want to bring out the colors of the barn

  • Select the Barn layer

Layer>New Adjustment Layer >Vibrance

  • Click OK
  • Increase the vibrancy and saturation sliders

OR

  • Select Barn Layer
  • Choose Create new fill or Adjustment Layer:
  • Choose Vibrance
  • In the dialog box than opens, increase vibrance and saturation sliders:
  • Paint over the Barn

Next, Let’s add text: “Here I am washing my new car”

  • SelectWindow>Character

The text we add will go to a new Text layer

  • Use a color of your choice, a script font, about 30 pt, a contrasting color
  • Can pick up a color from the image:
  • May want to move it above the car layer
  • File>Save (psd)
  • Save again as jpg

My Final Version:

OK, let’s finish up

  • How would you Save for Web
  • Create a new html page and insert the car jpg version
  • Save the page as colorize.htm
