I would like to know if flash will be needed if photographing cars at a car show, as there is lots of spotlights and i understand that the light will bounce off the car giving lots of reflection. I will be using the canon 420ex speedlite with a omibounce which i hope will help. If there is anyone willing to give some tips will be appreciated.
Also i like to know if inside an arena where everywhere is pitchblack except for some lights how is it possible to get the best pictures as lighting will be quite bad, only some spotlights as the cars will be racing around. By the way i'm using a SLR to take pictures as well.
