Lighting Tool Instructions Click on the Lighting Tool button on the main toolbar to get the Lighting Tool controls: Lighting Control Bar The Lighting control bar is the bar with the title "Lighting" on the left end of it. Lighting Title Button Mouse over the "Lighting" title button to pop up an overall lighting help window. You can also mouse over the other controls to pop up a help window. Brush On Brush on is the normal tool for brushing on the lighting, which is a lightening or darkening of the surface. When the Lighting Tool is launched, the palette automatically switches to a gray scale to allow selecting the desired level of highlight or shadow. The neutral button is shown depressed as a convenient reference. Pick a button to the right to darken, left for highlighting. In addition, the controls on the right of the control bar allow selecting a lighting level. You can pick a value from the drop-down list, increment or decrement the existing value, quick-select zero, or directly enter a value. You can also pick a value off the 3x3 natural lighting matrix, described below. Erase Click the Erase button to get a brush that will remove lighting from an area by painting on neutral lighting, neither highlight nor shadow. If the Erase button is down, you can press All to erase the entire layer. Fill If there is an area to receive uniform lighting, and it is totally bounded by either lines or the edge of the layer, then it is quicker to use the Fill Tool. Press the Fill button and click on the area and it will be filled with the selected lighting. Sample Very often you want to add lighting with respect to what is there already. You want to darken it a little or lighten it a little. Click the Sample button to get a one-shot sample tool. Click on the area of interest and the average lighting under the brush will be selected. The sampled lighting level will appear on the palette, and you can select something lighter or darker than that. Blend Use the Blend tool to create a gradient transition between two levels of lighting. Keep clicking and dragging to move the lighting around until it looks right. All Click down the All button when you want to erase the entire layer. In the case of lighting, the All button only works with erase. Natural Lighting Matrix Use the 3 x 3 natural lighting matrix to select starting highlights and shadows for various surfaces. The first row of buttons relate to the surface most directly in the path of the sun or light source, the primary surface. Row 2 is for the secondary surface, and row 3 is the tertiary surface. A cube will typically have 3 faces lit by the sun. The first column is the sunlit highlight value. The second column is the indirectly lit back side of the surface, and the third column is for shadows cast on the sunlit surface. Lighting Chroma Adjust the slider to increase or decrease the amount of chroma in the lighting color as it is being applied. The overall amount of chroma for highlights, shadows, and background can be set with the Layer/Lighting Color controls, and this slider will provide localized modifications of the overall setting. You can make a few highlights more brilliant than others, for example. In the Munsell color system, chroma is the distance away from the gray axis. Increasing chroma makes the color less gray. Decreasing the chroma makes it more gray. © Copyright 2007 ColorCap Software. All rights reserved.
