Photography students, questions about metering and focusing.

I haven't used 1.5D3, so I can't answer it.

2. There is no conflict between metering and focusing. Photometry defaults to the central area of the camera, so it is not wrong to set exposure parameters based on the photometric points.

3. Different areas can be set for the focus, which is convenient for composition. You can also lock the focal plane by pressing the shutter half-way, and then make a composition. The focal plane will not change because of the change of composition.

4. HDR can be used for backlight shooting, but in fact, if you expose one according to the person, expose one according to the sky, and then change the sky directly, HDR is not effective.

5. Backlight can be filled with flash.

6. It is best to choose in the morning or evening when the light is not too strong, so that when you fill the light through the reflector or flash, you can take into account the brightness of the characters and the level of the sky at the same time. If the light is too strong, give priority to people, and then use the sky material to add the sky again.
