How to dim Canon's 60D camera when taking photos in darkroom?

In addition to using the night mode, turning on the flash and turning on the focus auxiliary light, the following measures can be taken to improve the focus success rate:

1, increase the ISO value (for example, to ISO 400,800, 1600 or even higher).

ISO value is a measure of the sensitivity of digital camera to light, which is usually expressed by ISO value. The greater the value, the stronger the photosensitivity, and the smaller the value, the weaker the photosensitivity.

When there is insufficient indoor light or shooting night scenes, using high ISO value can greatly increase the success rate of focusing. But the noise of the photo will also increase accordingly.

2. If the ambient light source is dark, you can increase the exposure value (such as ++ 1EV, ++2EV) to highlight the clarity of the picture.

In the process of digital camera shooting, if you press the half shutter, the LCD screen will display a picture similar to the final effect, and focus and exposure will start at the same time. The exposure at this time is the exposure of the final picture.

If the picture is obviously bright or dark, it means that the automatic metering accuracy of the camera has a big deviation, and exposure compensation should be forced.

Digital camera can browse the picture immediately after shooting, and at this time, you can see the brightness of the shot picture more accurately, and there will be no discrepancy. If the shooting result is obviously bright or dark, it is necessary to shoot again and force exposure compensation.

Be sure to ensure the stability of the camera when taking pictures, and the camera shake will also cause the photos to be out of focus and blurred.
