Nikon D50 Manuel D’Utilisation

Photographs taken at slow shutter speeds are prone to blurring.  If sensitiv-
ity is raised above the default value of ISO 200 equivalent, the same expo-
sure can be achieved at faster shutter speeds, preventing blur.  Sensitivity 
can be set to values between ISO 200 and ISO 1600 in steps of 1 EV.

➤ Shooting menu ➤ ISO

If the monitor is off, sensitivity can be set by press-
ing the 

  (ISO) button and rotating the command 

dial until the desired value is displayed in the control 
panel.

“Sensitivity” is the digital equivalent of fi lm speed.  The higher the sensitivity, the 
less light needed to make an exposure, allowing higher shutter speeds or smaller 
apertures.  Just as higher speed fi lms tend to be “grainy,” pictures taken at high 
sensitivities are prone to mottling.

At default settings, manual sensitivity adjustment is not  available in 

 , 

 , 

, 

 ,   , 

 , and 

 modes.  Instead, the camera adjusts sensitivity automatically.  To 

adjust sensitivity manually, select Off for Custom Setting 9 (ISO Control; 

 91).
