Sony 190 camera

190 is a professional camera with two operation modes: manual and automatic.

If it is fully automatic, the white balance, gain and electronic shutter parameters are all detected by the camera itself. Just press W-T..

190 is followed by an "auto-lock" option. If you select it, it will be fully automatic.

If it is manual operation, it needs to be adjusted.

1, white balance

White balance is used to tell the camera what is white. Only when the camera understands white correctly can you restore the color of the picture normally.

There are two ways of white balance: preset and manual adjustment.

2. Exposure parameters

Exposure refers to the brightness of the picture, which has three functions: aperture, gain and electronic shutter.

Aperture is the main light entry control of the camera, which can be used automatically or manually.

If the amount of light entering the aperture is insufficient, the gain can be increased.

Gain is a way to amplify brightness through electronic circuits.

3. Gray pills

When the amount of light entering is too large, you need to add a gray piece to limit it, which is ND. If necessary,

You will be prompted on your LCD screen.

4. Color temperature

The color temperature of 190 camera is tested by the machine itself, so it is unnecessary to set it.

If you are not sure about the parameters, then the best way to shoot is automatic shooting.

Just select "Auto Lock" on the back of the camera, and the rest is to dial the corresponding gray meter if the camera LCD prompts "ND 1" or "ND2".

This is the recovery process.

The main work is "subject determination" and "scene determination". . . . . . at work
