Objectives: Students learn to use Selection tools.
Essential questions:
1. How and when to use Marquee tools?
2. How and when to use Lasso tools?
3. How and when to use Quick Selection and Magic Wand tools?

 

Save the file and open it in Photoshop.

These are the selection tools. They are grouped together. We are going to use all of them for this project. Some of them will be much easier than the others. But it is really important to try them all.

The only tool we are not going to use is the last one - "slice tool" - it is for Web graphics.


The first group of selection tools is called "Marquee Tools".

Rectangular and elliptical marquee tools will let you make rectangular or circular selections.

Single row and Single column tools will let you select a row that is 1 pixel high or a column that is 1 pixel wide.

Right now select an Elliptical Marquee tool. We are going to select a circle.

To make a round selection you just click and drag the cursor over the area that you want to select.

Try it.

If you want to select a perfect circle (or a perfect square) hold SHIFT while dragging.

If you want to start your selection from the center out hold Option (Alt) button.

If you want both of these options (perfect circle drawing from the center) hold both keys.

Try it!!!

Now zoom in the area with the blueberry. Select it.

The next step is to move the blueberry over the carrot slice.

Move tool is for moving!

Select the Move tool. Place it inside your selection. Do you see the cursor changed to scissors? By using this tool right now you are cutting the blueberry out of the background in order to reposition it.

Drag the selection over the carrot slice.

While your blueberry is still selected, you can adjust its position (with a mouse or using the arrow keys on the keyboard)

Once you deselect it - it it permanently embedded into the image.

Deselect:
Select > Deselect on the menu bar
or Command D (Ctrl D)

Use the same Marquee tool to select the carrot slice.
Double-click the Hand Tool. It will zoom out the image so you are able to see it all.

Use the Move tool to drag the carrot over the melon.

See? It looks like an eye....

DO NOT DESELECT YET!!!!!!

Let's add the second eye.

It is important that your carrot is still selected.

There is a way in Photoshop to duplicate selections and move them at the same time.

Choose the Move tool.

Place the cursor inside the selection (carrot).

Hold Option (Alt) key. See a small plus sign? Keep holding it down.

Now move you carrot to create another eye.

Position the second slice.

Release the mouse.

Release the Option (Alt) key.

Next - choose the Magic Wand Tool.

Magic Wand selects the pixels that are of a similar color.It works better to select objects that are of a uniform color.

In our case it will be the pear.

You are going to select it with the Magic Wand.

 

 

So... Select the tool.

 

 

 

Then look at the Option bar.

 

Set Tolerance to 32. That means that the Magic Wand will select all pixels within the range of 32 shades darker than the initial color and 32 shades lighter than the initial color.

To set the initial color - click on the dark yellow area of the pear.


See? All pixels that are within the range were selected.

What about the light yellow part?

 

To add to existing selection - hold SHIFT

 

 

Hold down Shift and click on the light yellow area.

The entire pear should be selected now.

Double-click on the Hand Tool to view the entire image.

 

 

Choose Move Tool.

 

Drag the pear over the melon.

Looks like a nose?

Zoom in the area with the kiwi.

You are going to select it. One way to select is to use the Elliptical Marquee Tool.

You are going to use Quick Selection Tool.

This tool is a cross between Magic Wand and a Brush Tool. It selects as you move it around.

You can change the size of it in the Option bar.
I chose size 8.

Now place it over the kiwi and click, hold the mouse and move the cursor over the green area.

Don't hold it too long - it will select too much.

If it did not work right - deselect and start over.

Move the kiwi over the melon (use Move Tool).


The next tool to use is Lasso Tool. Lasso is a freehand selection tool. You can draw your own selection.

 


Zoom in the area with the mushroom.

To select mushroom draw the selection around it. Try to stay close to the shape. But if you don't - not a big deal. We'll fix it.

Remember - drawing your own selection - you need to return to your start point. Selection is a closed shape. So you need to end at your start point.

If you need to fix your selection:
use SHIFT to add to selection
use Option (ALT) to subtract from selection

Move the mushroom like you see on this picture.

Zoom in the area with the grapefruit.

You are going to use Magnetic Lasso Tool. It is similar to Lasso Tool. It also allows you to "draw" the selection, but.....

Magnetic Lasso will snap to the edges of the objects that you draw. Actually, it snaps to the biggest contrast between the colors (values). Usually, the biggest contrast is the edge of an object vs. the background.

This is what you do:

1. Click at the bottom left corner of the grapefruit with your Magnetic Lasso tool
2. Start dragging the tool outlining the top part of the shape. Stop at the bottom right corner.
3. Double-click at the bottom right corner. It will close the selection with a straight line.

Move the selection towards the melon. You are going to make an ear out of it.

Next - rotate the ear ( and resize it)

To do this go to Edit > Transform > Free Transform
or Command T (Ctrl T)

You will see a bounding box around the selection.

Inside the bounding box is a Rotation point. Think about it as a pin that holds the shape. If you rotate the shape the pin would stay where it is now. You can move the Rotation point within the shape or outside the shape.

Place the cursor next to a corner of the bounding box. The cursor should become a double-headed arrow.

Rotate.

To resize the shape drag a corner of the box.

To resize without distorting and stretching the selection - hold SHIFT while resizing.

After you're done - press RETURN (ENTER).

Choose Move Tool.

Duplicate the ear.
(hold Option or Alt while dragging)

Flip the ear:

Edit > Transform > Flip Horizontally

Deselect

 

For the next task you will be using two tools: Lasso Tool and Polygonal Lasso Tool.

Polygonal Lasso Tool allows you to make selections with straight segments. All you do is click.. click... click...

Zoom in the area with the bow tie pasta piece.

Choose Lasso Tool


 

 

It is really important to follow the steps exactly as they are described:

1. Start at the upper left corner. Click and drag the selection line following the shape of the bow tie. Stop at the upper right corner.

2. Do not release the mouse yet!!!

With the mouse down, hold Option (Alt) key.

3. Now release the mouse (still holding the Option (Alt) key down). The cursor changed to Polygonal Lasso Tool.

4. Start clicking to follow the pasta's zigzag shape.

5. Stop at the bottom right corner.

6. With the mouse down, release the Option (Alt) key. The cursor changes back to Lasso Tool.

7. Follow the shape of the pasta and stop at the bottom left corner.

8. Holding the mouse down, hold Option (Alt) key. Draw the left zigzag side.

9. Finish your selection at the start point.

The last selection to make is the intricate shape of a bunch of radishes.

We are lucky we need to select this complex shape from a solid color background (white).

There will be 2 steps in selecting it:

1. Use Rectangular Marquee Tool and draw a rectangular selection around the shape. Make sure you just get the white background into your selection.

 

2. Choose Magic Wand Tool. You are going to deselect the white area from this rectangular selection. Remember? To subtract from selection you hold down Option (Alt) key.

So... Holding the Option (Alt) key - click on the white area inside the selection. This will leave you with a perfect selection of the radishes.


Move it above the eye.

 

Duplicate it:

Use move Tool and hold Option (Alt)

Flip the eyebrow:

Edit > Transform > Flip Horizontally

 

You are almost done!!!!

Deselect

 

Now let's get rid of the left side of the image!

Choose Crop Tool

Draw a box around the Melonhead person.. :)

 

You can adjust the size of it (and even rotate)

 

Press RETURN (ENTER)

 

File > Save

You are done!!!!

This is what it should look like!

Type your name and print it out!
