1Page Photo Studio Optimizer Version 5 Release 13
PrefaceWelcome to Version 5 Photo Studio Optimizer! This new product is a dedicated Photo Studio workbench and represents an essential complement for users who want to create images and movies that will match reality.
Indeed, Photo Studio Optimizer empowers Photo Studio`s rendering capabilities with advanced technologies such as Global Illumination and Caustics.
Photo Studio Optimizer offers powerful tools to improve "like real" sensation. Thanks to 3D Texture and Bump Mapping functionalities, users will see what will be the product appearance at the beginning of its physical lifecycle.

Using This GuideThis guide is intended for any users wishing to generate photorealistic images of products.
All users should be familiar with basic Infrastructure concepts such as document windows, standard and view toolbars as well as the 3D compass.
This guide is organized as follows:
Getting Started tutorial provides information for starting a Photo Studio session
User Tasks section guides you step-by-step through basic procedures such as managing light sources, 3D textures, and so on
Glossary provides keyterm definitions
Index provides a list of terms specific to product image.

Where to Find More InformationPrior to reading this book, we recommend that you read the Infrastructure User's Guide.
You may also find useful to read the Real Time Rendering User`s Guide that allows you to define material specifications that will be shared across your entire product development process as well as map materials onto products to produce photorealistic images.
Certain conventions are used in the documentation to help you recognize and understand important concepts and specifications.

Getting StartedThe following tutorial introduces the basic functionalities you need to be familiar with when using Photo Studio Optimizer.
It provides 2 step-by-step tasks for:

All together, these tasks should take 15 minutes to complete.

Entering the Photo Studio Workbench
This first task will show you how to open the Photo Studio Optimizer which is accessible via the Photo Studio workbench.
The only pre-requisite for this task is to have a current Version 5 session running.
1. From the Start menu, select the Infrastructure->Photo Studio command.
The Photo Studio workbench is displayed:

Defining a Scene
This task gives you a quick methodology to define the parameters involved in the scene creation, i.e. light, camera, textures.
Open the Cat.CATProduct document.
Select the Shading with Material icon from the View toolbar.
The product looks like this:
1. Create an empty environment (either box, cylindrical or spherical).
2. Choose the point of view you want to use then click the Create Camera icon .
3. Click the Create Spot Light icon to define a conical light source then orientate the
light as you wish with the help of the light preview on the environment walls.
Set the lighting attenuation in order that it does not end before the environment, otherwise the environment will be almost entirely shadowed.

4. Click the Quick Render icon to check the result. Perform as many modifications as
necessary and check that what you get is really what you want to lit.
5. Apply a texture on your environment and your part(s) by clicking the Apply Material icon
and check the result by creating a quick render.
Once you are satisfied, you can create a shooting to have a finer result. To do so:
6. Click the Create Shooting icon to define the shooting parameters.
We advise you not to modify the default shooting parameters except those concerning
accuracy. When the accuracy parameters is set beneath the mid value, you should
obtain a result nearly as identical as the quick render.
12Page Photo Studio Optimizer Version 5 Release 13
7. Click the Render Shooting icon then the Render Single Frame button to check the
result. Go back to the material Properties to correct the parameter definition if necessary.
Here are a few tips for lighting parameters:
Ambient: use very carefully the Ambient parameter ("good" values are around 10%) to avoid final color saturation
Diffuse: start by setting the Diffuse parameter to the minimum intensity: when you define the material lighting, the sum of all parameters (except Shininess) should be roughly equal to 1 to render the material with realism, but nothing forbids you to choose higher or lower sum values to achieve special effects: they may simply be harder to control
Reflectivity/Specular: set the Reflectivity and the Specular parameters simultaneously
Transparency: if the material is transparent, define a Transparency value. We recommend you to define this parameter at the end.
8. When the result is satisfactory, adjust the shooting parameters to refine the result such as
the reflection number, the anti-aliasing, etc. in the Shooting Definition dialog box.
9. Click OK when you have finished.
