Controlling the brightness
Brightness (or exposure) is closely linked to depth of field. Brightness is governed by three factors: aperture (or iris), shutter speed
and gain. In a well-lit setting, an ND filter can be used to control the light level and enhance the "bokeh" effect.
Gain/ISO
The NEX-EA50 allows for higher gain (or ISO) settings, where
the image signal level is amplified electrically to boost the
image brightness. In this way, the NEX-EA50 can produce
excellent images with minimal noise in low-light settings such
as a darkened stage, where conventional video cameras would
have too much noise.
* Gain and ISO sensitivity can be set independently, with priority
given to either as required.
How to set/operate
1. Set the AUTO/MANUAL switch to MANUAL.
2. Press the GAIN/ISO button to display the gain or ISO value.
3. Set the gain switch to H, M or L as required.
Setting range:
Gain H (18 dB) M (9 dB)
ISO H (800) M (400)
TIPS
The gain and ISO settings can also be modified via the menu system. Navigate to CAMERA SET then either GAIN SET or ISO SET.
L (0 dB)
L (160)
ISO range: 160 – 5,000
When the GANMA picture profile is set to ITU709, the ISO range becomes 200 – 6,400.
Note: ISO range may differ for other picture profiles.
9 9
Gain range: 0 dB – 30 dB
