Ok, this is it.
How do I brighten this image up like a sunny day? Is it to do with my
global settings?
#version 3.5;
global_settings {assumed_gamma .6 max_trace_level 10}

I use to set the (sun) light color at 1.5 or 1.8.
Put no_shadow to your clouds might help too

Just need more contrast.
Try upping the light.
Try #default{finish{ambient 0}}.
Try sphere{CamLoc,.0001 pigment{rgbt <.5.5.5,2>}}
Try dimming whatever fill light is lighting your shadows

The traces left by the wheels are missing! Where is the shadow under the buggy?
You may have to much ambient, try something less than the default of 0.1.
A low value for the assumed_gamma can wash out contrasts and shadows, try 1 or a
little more.

Scenes in direct sunlight have very harsh and rather dark shadows. These
will add contrast to your scene. Light the scene by one strong light and
maybe a weak fill at some places. Also, make sure to use a slightly
yelowish light instead of pure white.

I haven't got that far yet! ;)
Btw, you do know that this buggy is about 3 feet off the ground?
> Where is the shadow under the buggy?
It's there, but contrasted out of all recognition. Washed out, in other
words... :o/

Playing around with this right now. Thanks.

Yes, definately.

That last one is the problem, I think. Thanks Shay, I'm playing around
with these right now, but what does that CamLoc thing literally do?

You've done this Marc? That's cool. I'd love a go at it, not as a serious
sporting hobby, but a quick ten minute sprint down a loooong clear beach
would be fun - that would do me for life, I think... ;)
When you say a 'sidewind', do you mean at an angle of around 22 degrees?
This would make sense to me.
Another thing; are you guys strapped in at all? From the images I found on
Google, I couldn't make out if they were strapped in or not.
the strings are loose and short

'CamLoc' was just my abbreviation for Camera Location. The contrast of a
scene can be strengthened by adding a small sphere around the camera
with a gray color and transmit > 1. I think Rune was the first to try this.
