Photography is straightforward.

I am a senior photographer. Let me give you a systematic answer:

You tend to miss. Why? Because you stand up straight when you shoot, you look straight into the viewfinder and everything you see is positive. Even if the camera is tilted, because your eyes are looking straight, you think it is positive, which is the key factor causing the tilt.

How to solve this problem? It's simple. It's called asking for help. In your picture, there must be some horizontal or vertical reference lines that your eyes can see, such as the horizon, such as doorframes, such as telephone poles, and even people standing straight. It is very useful to take them as your reference objects and observe whether they are parallel (or vertical) to the horizontal and vertical borders of your camera picture in the picture. However, it should be noted that if the lens you use is ultra-wide-angle (the equivalent focal length is below 24MM), then the edge distortion and perspective distortion will lead to the original straight line distortion. At this time, the horizontal and vertical lines you need to refer to must be near the center of the picture.

Through some technical assistance, such as setting the auxiliary line of the well in the viewfinder (available in 700D), the auxiliary basis of the above method can be increased. In addition, it is also a common method to use software to make secondary composition by cutting (as long as it is not too crooked, it will not lose many pixels).

Practice with the above methods, you will become more and more experienced and shoot more and more accurately.

There are still questions to ask, all of which are manual, and I hope to adopt them.
