The convoy drive to Cadwell is an event in itself, the sweeping roads through the Lincolnshire wolds and the smell of unburnt hydrocarbons mixed with the faint aroma of a McD flat white were setting me up for another great day. To cap it all it’s a bank holiday Monday and the Gods have been kind, the weather is amazing.
Before we go any further a word on checking your gear. The night before an event I will charge my batteries and format my storage cards; don’t just delete your old images it's not good for the cards. Then I will check everything ensuring that all the lenses work and are clean. Take a picture of a white or neutral wall load the image into your computer and check that you don’t have marks on your lens or sensor.
On arriving at the show check the following basic settings:
ISO. Sunny day ISO 100, dull day push it up to get the shutter speed you need. Remember the exposure triangle ISO, aperture and shutter speed, changing one will have an affect on the others.
Metering. Area mode unless it’s very tricky lighting, spot metering generally isn't great for automotive photography and definitely don’t use it for track work. A white car will under expose and a black car will over expose your image if you are set to spot metering. I take a shot of the track before the racing to confirm I have all my settings in correctly.
Focus setting. I have two user setting on my camera that I pre-program. One has continuous auto focus with back focus using 9 segments, AF-C on a Nikon which I use on track. The other is single focus AF-S with one segment for the static shots and if I want to pre-focus on part of the track.
