Like this location for some funky color saturated 100 Speed/ Aperture pictures - I like the painting quality - of it - but its sort of a crap shoot as to which car is there because you have to be on one section of the track going at speed and they (AI) have to be on other section - and Turn 1 is a great place for the A1 to dent the cars. - This is cropped only, no other effects.
InitialB's Shelby Paint at Turn 17 Sebring at night - I took a ton of pictures here and while I think this is a bit dark - I like the "It's night time racing feel" Shelby at Turn 17 by Sean McManus, on Flickr
Its COTA - you have to be around the emergency vehicle between t16 and T17 (right before the observation tower - shoot through two fences to the cars coming around T14 or between 14 and 15
I have a Formula E (not sure who's paint but its yellow) and more a side on view I haven't shared - My first picture and thought so every time I race there in career - I always look for some shots on the first lap before the cars are terribly dinged up.
