The photos taken by Canon SLR camera 70d are relatively dark

Darker photos indicate inaccurate exposure, which is called underexposure in photography terms.

Underexposure means underexposure. It means that during the photography process, the brightness of the light felt on the photosensitive material is insufficient due to insufficient estimation of the brightness of the subject. The result of underexposure is that the subject is dark, lacks brightness and contrast, and the image texture is coarse and noisy.

The reasons for underexposure when shooting with SLR cameras generally include the following aspects:

1. Taking photos in automatic mode under backlight conditions

2. Exposure compensation The setting is set to reduce the exposure

3. Press the shutter when the viewfinder prompts that the exposure is underexposed

4. Use the flash to take pictures at night

5. Taking photos in a large area of ??light color

6. Using spot metering but not aiming the metering point at the subject
