00:00:00.09 --> 00:00:02.08

- Illustrator uses the word 'blend' in two



2

00:00:02.08 --> 00:00:05.00

very different ways.



3

00:00:05.00 --> 00:00:06.08

First you have the object blends that we



4

00:00:06.08 --> 00:00:09.04

encountered back in

Chapter 23 of the advanced



5

00:00:09.04 --> 00:00:11.08

course in which you create a series of



6

00:00:11.08 --> 00:00:15.04

sequential intervals

between two path outlines.



7

00:00:15.04 --> 00:00:17.09

Second, you have the

topic of this chapter,



8

00:00:17.09 --> 00:00:20.04

Blend Modes, which

allow you to combine the



9

00:00:20.04 --> 00:00:22.08

colors of a selected object with those



10

00:00:22.08 --> 00:00:25.09

of the objects below in

a variety of different



11

00:00:25.09 --> 00:00:28.06

and potentially interesting ways.



12

00:00:28.06 --> 00:00:30.02

Now, unlike object blends,



13

00:00:30.02 --> 00:00:32.04

which rely in part on the blend tool,



14

00:00:32.04 --> 00:00:35.05

blend modes are expressed

as a long list of items



15

00:00:35.05 --> 00:00:37.04

inside a popup menu.



16

00:00:37.04 --> 00:00:39.01

And so they have names.



17

00:00:39.01 --> 00:00:41.04

For example, there's the multiply mode,



18

00:00:41.04 --> 00:00:43.07

which creates the effect

of printing one ink on



19

00:00:43.07 --> 00:00:46.04

top of another so everything darkens.



20

00:00:46.04 --> 00:00:48.05

There's the screen mode which works like



21

00:00:48.05 --> 00:00:50.05

shining your path outlines from a bunch



22

00:00:50.05 --> 00:00:53.02

of flashlights onto a single screen so



23

00:00:53.02 --> 00:00:55.02

everything becomes brighter.



24

00:00:55.02 --> 00:00:57.07

There's difference, which

subtracts the colors in



25

00:00:57.07 --> 00:01:00.03

one object from those behind it to create



26

00:01:00.03 --> 00:01:04.06

on the fly inversion

effects and many, many more.



27

00:01:04.06 --> 00:01:08.00

In this chapter we'll also

address opacity masks,



28

00:01:08.00 --> 00:01:10.03

which let you paint in transparency,



29

00:01:10.03 --> 00:01:12.05

typically within the confines of a group



30

00:01:12.05 --> 00:01:13.08

or a layer.



31

00:01:13.08 --> 00:01:16.02

Add a black object to an opacity mask,



32

00:01:16.02 --> 00:01:17.06

and you create a hole.



33

00:01:17.06 --> 00:01:20.04

Add a white object and

you eliminate the hole.



34

00:01:20.04 --> 00:01:24.01

A gradient results in a

gradual fade and so on.



35

00:01:24.01 --> 00:01:26.03

For those of you who

may know Photoshop and



36

00:01:26.03 --> 00:01:29.02

opacity mask in

Illustrator works very much



37

00:01:29.02 --> 00:01:30.07

like a layer mask.



38

00:01:30.07 --> 00:01:32.06

Okay, so obviously,



39

00:01:32.06 --> 00:01:34.06

we have a lot of ground to cover,



40

00:01:34.06 --> 00:01:35.08

and so you might ask,



41

00:01:35.08 --> 00:01:38.03

why take on two such disparate topics



42

00:01:38.03 --> 00:01:39.07

in a single chapter.



43

00:01:39.07 --> 00:01:42.03

Because blend modes and opacity masks



44

00:01:42.03 --> 00:01:45.07

reside side by side in the opacity panel.



45

00:01:45.07 --> 00:01:48.00

Meaning that they're

ultimately varieties of



46

00:01:48.00 --> 00:01:50.04

opacity's opposite, transparency.



47

00:01:50.04 --> 00:01:51.05

In other words,



48

00:01:51.05 --> 00:01:54.03

blend modes and opacity masks allow you to



49

00:01:54.03 --> 00:01:56.03

see through one object to reveal



50

00:01:56.03 --> 00:01:58.00

the objects below.



51

00:01:58.00 --> 00:02:00.01

Dang, I should've led with that.



52

00:02:00.01 --> 00:02:02.03

Well, I guess that's a rare example



53

00:02:02.03 --> 00:02:03.07

of me being opaque.



54

00:02:03.07 --> 00:02:04.05

Get it?



55

00:02:04.05 --> 00:02:06.03

Because I wasn't sufficiently transparent



56

00:02:06.03 --> 00:02:07.03

with my information.



57

00:02:07.03 --> 00:02:10.01

Here, let me clear things up.
