03. SU Podium V2.6 Quick Start - Intensity / exposure
The intensity/exposure sliders are one of several ways to manipulate the exposure/brightness of an image.
- As shown in the video, the "interior bright" presets are one way to boost the exposure of an interior image with relatively little natural light.
- The SketchUp date/time plays an important role in image tone and brightness when using either of the Podium physical skies.
- Hidden LEM materials, can be used to increase the amount of light in a natural, organic way. If you must use artificial "fill lighting" to brighten up a room, hidden light emitting materials are a better choice than omni lights. This is demonstrated in the video labeled LEM examples.
- Some visualizers will remove/hide a wall behind the camera to allow more light into an interior — just one more option to consider if you need to significantly increase the amount of light in your space.
- If a render is only slightly underexposed, it is often faster and easier to simply brighten the image in post-processing, instead of wrangling with the iterative process of making adjustments and re-rendering (which could take several hours).
Troubleshooting tip — Why is my render so over-exposed?
- Preset choice - If you use an interior preset for an exterior scene, it will end up overexposed.
- Accidental LEM material - Another common mistake is applying LEM properties to a material, but not realizing that several other objects in your model are using the same SketchUp material. For example: You apply LEM properties to a light-bulb, without realizing that the walls share that same material. Solution is to create unique materials every time you make an LEM.
- Make sure the "clay" option is not turned on. When this option is checked in the environment tab, all textures are turned off and surfaces will appear pure white.
