M file means pure manual operation, and you can control the aperture and shutter yourself. (But at this time, most SLR will automatically measure light for users' reference, but it will not interfere with users' settings. )
The significance of photometry is that the machine provides you with the number of apertures and shutters. In automatic mode, the machine will determine the shutter and aperture according to the values obtained by photometry.
——————————— I suggest you learn the basics.
Let's talk about a common problem, that is, you don't know the knowledge of photometry, because the first question and the second question are the same.
Then answer them in turn.
1. The camera determines the exposure value by measuring the light and assigns the work to the aperture shutter. What you need to know is what metering modes the camera has. Different measurement models have a lot of knowledge about different measurement environments.
2. At this time, you may need exposure compensation and negative film compensation to avoid overexposure. Of course, if you master spot color photometry, it may be better to know how to find neutral gray photometry.
3. The same parameters, in theory, will not be much different, not visible on the LCD, but should be seen on the same monitor.
I suggest you look at the explanation of photometry in the reference materials, which is very detailed, from beginning to end.
It suits you.
And bloggers can't wait to answer your questions!
