Making of Black Pearl Treasure by Domenico Selvarolo

Step 12 - I used a hdr image with 2 luminous panel (red on the right and blue on the left). Luminous intensity set 5.0w/srm2 for the blue and 6.0w/srm2 for the red.

In luminous panel material I added a shader with the following settings.

These are the settings for the render and the final output color. Gamma set at 1.2 for a dark scene. I have activated the bloom.
