1, which mode does SLR outdoor portrait usually use? 2, shooting portraits in the backlight, people are very dark, how should I shoot?

1, it depends on what you are shooting.

If you take a portrait of a sugar water tablet with a solid front and a virtual back, give priority to the aperture, open the aperture, measure the light with central focus, and focus with single point.

Shooting motion, people who want to express motion through blur effect, use shutter priority, slow shutter, multiple continuous focusing or area continuous focusing.

Take a small clear photo of new Japanese style with automatic file plus exposure compensation+1 file, which is slightly overexposed but does not overflow, so you can directly measure the skin.

There is no fixed pattern for shooting portraits with humanistic themes. Instead, use a small wide angle of 35mm or a pan-tilt to control the exposure according to the actual situation.

2. Backlight shooting:

Use central focus photometry or spot photometry to measure skin. But maybe people will be exposed when they are normal.

You can also use a flash to fill the front light, but the top flash tends to make the photo too dull. It is best to have an outboard flash as side light.

You can also divide metering and adjust exposure parameters according to the dynamic range. At present, the dynamic range of SLR is about 7 gears, and the PS drawing curve is relatively late.
