    Brands Hatch BTCC - Amateur trying to improve...

    Hi, I am relatively new to photography and this is only my second experience at motorsport photography. I'd really appreciate some critique. All images were taken with a Canon 70D and Sigma 70-200 lens and edited in Lightroom. Thanks for looking. Mike
