Initial value

SHUTTER

The use of an electronic shutter function enables shooting

 

 

with proper brightness, as more brightness results in higher

 

 

shutter speed.

 

 

The ExDR function allows even the shooting of a subject

 

 

having different luminous flux density by composing a picture

 

 

shot at 1/100 (1/120) sec. shutter speed with a picture shot

 

 

by a high-speed shutter. ( ): TK-C1480U

 

 

NORMAL: This fixes the shutter speed to 1/50 (1/60).
