• Better color depth

  Better color depth

  Color depth refers to the number of unique colors that a sensor can faithfully capture. Cameras with better color depth will demonstrate smoother transitions from one color to the next, and avoid "banding" in areas with subtle shading. (Blue skies are an example of where you might see color banding.)

  More color depth is generally better, but you'll struggle to notice a difference between two cameras with less than 1 bit of difference. Color depth above 22 bits is considered excellent.

  23.2 vs 20.2 bits
  Capture richer, more accurate colors
• Higher effective ISO

  Higher effective ISO

  Maximum effective ISO is an estimate of the highest sensitivity at which a camera can capture excellent quality photos.

  Cameras with higher effective ISO will be better choices for indoor photography, night shooting, and indoor sports photography, especially if you intend to make large prints.

  You can learn more at our glossary entry.

  791 vs 189 iso
  Take photos in low light with less noise
• More dynamic range

  More dynamic range

  Cameras with more dynamic range allow you to take photos with dramatic differences in highlight and shadow areas while retaining detail in both.

  Think of a brilliant sunset on a rocky beach: Bright sunset in the background, with dark rocks in the foreground. High dynamic range means more of the extremes will be faithfully reproduced.

• Longer stills battery life

  Longer stills battery life

  Cameras with longer battery life can take more photos before exhausting their batteries.

  Special note: The measurement standard for battery life stipulates that if a camera has an internal flash, it must be used for 50% of photos taken. For this reason, comparisons of one camera with an internal flash to another without will not be comparable
