How to keep flat and steady in photography

Flat means that the horizontal line is not crooked, that is, whether the image you see when taking pictures is horizontal or vertical. This requires you to take pictures and straighten the machine. Don't shoot sideways.

Steady means that your hands don't shake when you take pictures. Because the first condition of clear image is to make coms or ccd fully sensitive within a certain period of time. For example, it takes ten seconds to take a clear picture, but your hands are shaking. Isn't that unclear? Generally, as long as the card machine can keep at 1/30 seconds, it can shoot clearly. It's better to be over 1/60 seconds. Use high iso in dark environment. Or turn on the flash.
