Rant

One thing that bugs me is when people ask "what settings were you using" when in Photography there is no real right or wrong settings for a particular situation. I have rules I tend to abide by but that is just personal preference when I shoot. I have relatively steady hands and almost always shoot handheld so I tend to run as low as 1/60th combined with the flash to get a sharp result. For aperture I like to stick around the f8/10 range as the car remains in focus and optically my lens/camera excels here. I always use a circular polariser, if you do any car/bike photography then these are a must as it controls and often completely cuts out unwanted reflections on metallic objects so I make sure I always have my CPL handy. Other than that it's often just a case of trial and error, I run the flashes flat out at full power for the sole reason I can place the flashes further away from the car and obtain a wider spread of light, recycle times are increased but If you cant wait 4 seconds between shots you need a lesson in patience. No light meters, Umbrellas, 10,000W strobes with diesel Generators, 20 man production teams or professional photo retouchers here I'm afraid
