As Adobe Photoshop cannot manage the spectral information from Maxwell Render images, the Color adjustment layer can only mimic the high precision spectral changes that Maxwell Render performs, so this poses some limitations. The Color adjustment action performs a hue-saturation change, so it is not possible to change the color of a pure white emitter. In this case (and in general with pure white, grey or black desaturated emitters), we strongly recommend replacing the “Color” adjustment layer with a more complex “Channel Mixer” adjustment layer. The “Maxwell Layer Adjustment” action has been tested in Photoshop CS3, CS4, CS5 and CS5CS6.

There is a limitation in the Photoshop Standard versions (not present in the Extended versions), which means that the Adjustment Layers cannot be created in 32-bits mode. Because this action works in 32-bits and uses Adjustment Layers to allow non-destructive adjustments, it won’t work on the Standard versions of Photoshop. If you are using the Standard version of Photoshop, you can work around this limitation by converting your render to 16-bits (without merging) to be able to use the Action, as Photoshop is able to create Adjustment Layers in 16-bits. In 16-bits you will get a better result by setting your light layers to “Screen” blending mode, instead of “Linead Dodge (Add)”. Obviously, converting a 32-bits render to 16-bits will produce a reduction of the tonal range of the render. |
