Color correction layers like Exposure and White Balance can be applied to a single layer instead of the entire composite. You can do that by selecting a layer and then adding a new correction or by dragging the correction layer to another layer until an arrow icon appears. |
The Stamp, Display Correction, Sharpen/Blur, Denoiser, Lens Effects and Source layers are listed in the Layers panel by default to any rendered image. Their order cannot be changed.

Normally you would specify the ICC file for your calibrated monitor here. Programs like PhotoShop display images using your (primary) monitor's ICC profile automatically. However (at least for the moment), 3ds Max is not a color-managed application and you must manually load the monitor ICC profile into the V-Ray frame buffer in order to match the appearance of your images in PhotoShop. |
