Transparency is an effect CorelDRAW users have leveraged for many years to illustrate scenes that have a very photorealistic look The Interactive Transparency Tool the focus of this section is quite different in use and in the effect you achieve than the Transparency Lens You have directions for transparency such as linear and radial, and also have various operators accessed from the Property Bar to set conditions for how a partially transparent object interacts with an object below it One thing is good to keep in mind when working with transparency in a design: this is the way you blend colors between objects That s it; your work doesn t benefit from a totally transparent object there has to be some influence from the object to which you apply transparency, and it s usually color Therefore, an alternative and perhaps easier way to think about transparency is to think about color blending One of the keys to accomplishing amazing artwork using the Interactive Transparency Tool is the fill that a semitransparent object has; in addition to uniform fills, fountain and pattern fills can also take on transparency You put fills and transparency together, and you re talking seriously sophisticated compositions! Another key lies in how you approach a drawing in which you plan to feature partially transparent objects The best use of partially transparent objects is as an accent, an area here and there in a drawing to suggest a real-world object To illustrate a real-world object such as a piece of jewelry, transparency plays a part the gem in the jewelry, for example but there will certainly be nontransparent objects in such a drawing In short, use all the tricks and techniques you ve learned in s 1 through 21, and then apply transparency where the design areas call for it In the illustration here, you can see what is today a fairly common button for a web page; it suggests glass At left you can see a wireframe view; not a lot of objects went into a fairly convincing drawing of a glass button! With the Interactive Transparency Tool in combination with your own designer s eye, you can illustrate gases, smoke, fog, mist, and steam; you can also add reflections and highlights to your work to add detail, interest and a touch of glass

CHAPTER 22:

It s important to understand that if photorealism is your goal, you ll most certainly use effects in combination with transparency: the real world has clear objects, not transparent ones For example, if you want to illustrate a drinking glass, you would consider that glass bends light as light passes through it, glass is smooth and therefore reflects highlights, and glass casts shadows As an example, Claude Rains in the 1930s classic film was invisible; he didn t cast shadows, and he didn t show highlights when he did his thing if he did, he d be called The Clear Man, not a very good movie title Transparency in CorelDRAW doesn t create highlights or reflections this sort of thing you need to illustrate The Interactive Transparency Tool is a tremendous helper, but cannot complete the artwork you have in mind However, there s another property in real-world objects such as glass that the Interactive Transparency Tool does indeed imitate: tinting you ll see shortly that an object with some transparency can cast a tint on objects it overlaps, depending on the operator used for blending the object to underlying objects and on its own color For the discussions that follow, you ll need to remember only two terms and they re opposites Opacity is the amount to which you can see an object; transparency is the amount you can t see an object Therefore, 100 percent opacity is seen in a completely visible object, and 100 percent transparency can t be seen at all
