Flash has a gradient feature. This gradient feature has two forms: one is linear, and one is radial, and in your exercise files folder you'll see the project file for this. Linear, as it suggests, is a simple left to right. It can go up, down, or diagonally. And the radial feature can be of circular form or elliptical; it can even be tweaked them to an egg shape. So it's fairly limited; quite straightforward. It can't do anything organic, so if you want it to curve to an S shape, you're not going to have a good time with it. Nevertheless, as simple as it is, it can be used to pretty great effect as long as you work within those constraints.
Click the Zoom tool, or Z on the key keyboard. So if we look at the frame 1 of this file, you'll see what I call the "bowl of light". This is what it was called back in the golden age of animation where you could combine variations of different gradients to create an illumined spotlit area and favor that area for your animation action, or your staging. So that's the basic principle that we will be applying throughout the course whenever we use gradients. I'm going to show you the big problem that plague gradients in this program, and that's banding. This can happen in many programs; you will see it in Photoshop too if you get very, very subtle.
I find that this happens much more often when you use subtle gradients. And these red lines here; they are the transitions. Ideally of course, we would like to see a completely smooth from dark to light, and we're not seeing it. So this is something that we are going to have to continually watch out for. I've also noticed that depending on the monitor that you're using, you might see it or not see it. So depending on your output -- if you are going to be working for an iPhone this probably isn't going to be something that you need to be worry about. If you're going to be working for something that's going to be seen on a television screen or a larger screen, you really have to watch out for this.
I work on a Cintiq at home -- if you don't know, the Cintiq is the monitor that you can draw directly onto -- and I find that one of the drawbacks of the Cintiq is that the screen is a little bit darker. It's a tradeoff in the design of that Cintiq, or any of those screen tools. I would strongly recommend, before you get too deeply into this, that you test this pipeline for yourself; for your own workflow. Make sure that you are comfortable with whatever artifacts might or might not emerge. It comes down to your project; what it looks like. If it is going to be subtle like this, as you can see there is very little banding here.
I don't see very much evidence of it at all. You might see some beginning to appear here, but that falls within that band that I'm comfortable with. You might not be; you might be extra intolerant of it. It's just something to be aware of as we proceed through the course.
