3 Setting Noise ReductionN High ISO Speed Noise Reduction This function reduces the noise generated in the image. Although noise reduction is applied at all ISO speeds, it is particularly effective at high ISO speeds. At low ISO speeds, the noise in the darker parts of the image (shadow areas) is further reduced. Change the setting to suit the noise level. 1 Select [High ISO speed NR]. Under the [z3] tab, select [High ISO speed NR], then press . 2 Set the level. Select the desired noise reduction level, then press . X The setting screen closes and the menu will reappear. [M: Multi Shot Noise Reduction] This applies noise reduction with higher image quality than [High]. For a single photo, four shots are taken continuously and aligned and merged automatically into a single JPEG image. 3 Take the picture. The image will be recorded with noise reduction applied. With [High] or [Multi Shot Noise Reduction], the maximum burst for continuous shooting will greatly decrease. If you play back or directly print a 1+73 or 1 image with the camera, the effect of the high ISO speed noise reduction may look minimal. Check the noise reduction effect or print noise-reduced images with Digital Photo Professional (provided software, p.366). 131
