best renderings ever done by me using final gather... according to me
 

These are one of the best rendering i have done on MR... no lights!!!!!! only two poly planes with the incandacense level set to maximum.... and about the car... it was actually a game model... not mine... i souped it up to make it a high res car... all the details added by me... b4 its was only textures... and the wheels are completely mine!!! muahahaha

here is another one:::

Nice!
 

Nice rendering, on the second pic it looks like you could of tweaked the min max samples up a little, there seems to be some blotchy artifacts on the ground?

How long did it take to render?

yes..i wanted a bit of blotchiness.... only a 1300 rays.. and 1.200 max and .12 max and took a Min and 7 secs to render

here is another i got by playing with the poly planes


:Edit:

Facts about the FG of this one:

Rays: 7000 (hell yeah)

Max: 24

Min: 2.4

when I am messing with MR - I created a scene 1 plane, 1 sphere and 1 cube. created a nurbs sphere with a bit of incandescense and used preview final gather.

It looks good apart from the fact that there are no shadows? In your scene there are shadows - how do you get that look?

take a look at this example... here the poly plane (with a lambert shader and incadasence level set to maxiumum), it acts like a source of light.. (attached image)
