These photos are reviewed especially for your request regarding ballroom photography. Lightings in ballroom (indoor) are usually not enought to produce vivid sharp pictures. We got to sacrifice by using very high ISO hence creating noise (what to do) and at times unwanted motion (another what to do). Personally, i use a stronger point-flash but with a tracing paper over it... If ot flashes to bright at our audience (the people in our photo compositions), it would be not nice,
HAPPY PHOTOGRAPHING CREATIVELY
