Vue Atmospheres and Creating a Photorealistic Render
I generally use the Vue lighting setting of "GR" or Global Radiosity in my Vue Atmosphere Packs, as this does lend to more realistic Vue renders, a good realistic Vue Atmosphere is truly the key to the most photorealistic render. This creates the correct light color bounce from various objects in the scene, which can be tweaked and adjusted using the various settings within the Vue Atmosphere Editor. All of my Vue atmospheres come optimally set to give you the utmost reality in your renders, so if you change these settings, just be careful not to save the atmosphere back over the original file.
Global Radiosity vs Global Illumination in Vue Atmosphere Renders:
In my opinion, and generally in the opinion of most other experienced Vue artists, the ultimate in realism in your renders is gained from using Global Radiosity in your Vue Atmosphere lighting setup rather than Global Illumination. If you look around you, and carefully analyze how light interacts in the natural world, you will see actual Global Radiosity at work... Since we live in the natural world, and in an atmosphere that creates this 'scattering effect' our eyes can tell us what 'looks real' and what does not, even if we can't quite put our finger on it. GI simulates natural lighting to a degree, but it will not duplicate the realistic color bounce and 'shadow fill' as seen in the real world as the Global Radiosity setting will for the best and most realistic Vue atmosphere.

As seen in the above render, GR effectively duplicates the effect of color bounce and shadow fill. This is why in my Vue Atmosphere Packs I generally set them for Global Radiosity in the lighting tab of the Vue Atmosphere Editor. This, along with other settings and quality enhancements in the Vue Atmosphere Editor will allow you to simulate real world lighting and give you the most photorealistic render possible.
Tweaking the Vue Atmosphere for your Render
Since every scene is different, different lighting situations and requirements will come into play. Therefore when using the Vue Atmosphere of your choice from one of my packs, there are different things you can do to enhance the realism of your render for your scene. For instance, shadows are truly one of the keys to realism. We live on a world where one could almost describe our atmosphere as "soupy" at times. Light interacts with the particles in our atmosphere, bouncing to and fro, here and there. So depending upon the amount of light, the direction of light, and the atmospheric conditions the depth of shadows will change. Rarely in daytime anywhere on this globe will you find a truly pitch black shadow. Light scatters off of the particulate matter in our atmosphere and fills these shadows with reflected/scattered light. Within the Vue Atmosphere Editor, when you have the GR lighting selected, you will find a setting called "Bias".
The bias setting defaults to 0.00 in most standard Vue Spectral Atmospheres. What the Bias setting does is increase or decrease the amount of "shadow fill" in your global radiosity atmosphere. With a setting of 0.00 there will be no adjustment, leaving your shadows darker and deeper while increasing this setting (dependant upon your scene) to the positive will create more shadow fill, lessening the depth of the shadow. Try tweaking this setting and for those of you who have never tried it, you will be surprised at the results. For more in-depth explanations of this setting, I highly suggest purchasing Dax Pandhi's Vue Training Video's on Quadspinner (the link is on the Links Page), Dax creates some very high quality Vue tutorials which are a must have.
I will also be very happy to create any specific or custom Vue Atmosphere that you would like. Feel free to contact me via the contact page on this website.
