Excuse me, why is the photo taken by my Pentax kx so dark? How to adjust it? Are there any books that specifically introduce KX photography technology? Kneel down!

Even if exposed in mode A and mode P, the actual performance of the photos will be biased:

If your subject is in a dark background, the photo will be too bright. Solution: Reduce exposure compensation 1.5-2.5 files;

When your subject is in a bright background (such as backlit windows and the sky), the photo will be too dark. Add 1.5-2.5 for solution exposure compensation.

But digital photography is better than debt (relatively speaking), otherwise there is no room for revision later.

The environment is changing, so will the shooting. ...

It's the same to refer to any basic book, so you don't need to find "KX specialized in photography techniques"
