Exposure Control Lighting Effects - discreet 3ds max Tutorial

Jacquelin Vanderwood August 1, 2004   1 Let's start by looking at the original scene. Through the lens of the camera we can see a building with lamps place around it. It also contains a variety of lights that have been hidden. In this lesson we want to understand Exposure lighting and how to use it, so let's get started.   2 We can access Exposure Control through Rendering and Environment.   3 Here is the dialogue box that we will use to process the lighting.   4 If you click in the box you'll see Automatic Exposure Control, select it.   5 Click on Render Preview to see the changes.   6 Below Exposure Control sits the Parameters box. Depending on the type of exposure picked will dictate the what appears in the dialogue box below. For Automatic Exposure we see Brightness, Contrast, Exposure Value, Physical Scale, Color Correction, and Desaturate Low Levels. These are the current settings for the above picture.   7 If we change the settings to Brightness 40, Contrast 60, Exposure Value 1, Physical Scale 1000, and change Color Correction to blue, look at the change in the scene.   8 Our whole lighting scheme has changed because we've specified different parameters. Because we changed Color Correction to blue, we also see a change in the colors of the scene. (As a note: for best Color Correction use pale colors.)   9 All I've done here is change the color to yellow.   10 We can overexpose the scene by increasing Brightness and Contrast.   11 Here we've set Physical Scale to 800. What this indicates is approximately 800 candles more or less. Physical Scale only works on Standard lighting and not Photometric lighting.   12 By setting a negative value in Exposure Value we get a very dark scene.   13 To reset the lighting just select no exposure control. Play around with the settings. You'll find it much more easy to learn it that way.   Copyright 1998-2004, Jacquelin Vanderwood, All Rights Reserved
