Summary of common problems in novice photography

1. Why are the photos I took with a SLR blurred?

There are many reasons for blurred photos, such as blindly opening the aperture too wide, and eventually not only the background is blurred, but also the subject is blurred; For example, the shutter speed is set too slowly to capture the moment when the object moves, and only the motion trajectory is recorded; Or because of the focus, the subject looks blurred because it is not facing the person.

2. Why can't the aperture coefficient be adjusted or displayed in gray? Is the camera broken?

This situation is not that the camera is broken. At this time, think about whether the lens is not installed according to the correct steps. Align the red dot of the lens installation mark with the lens installation mark of the fuselage, rotate the lens, and hear a click, indicating that the lens is installed.

3. Why does someone take a big photo?

According to the perspective principle, the object close to the lens is large, and the object far from the lens is small. The wider the lens, the more obvious this phenomenon is. When you shoot with a wide angle, it is necessary to put the lens close to the model's face when shooting a close-up portrait. The final effect is that the face close to the camera is larger and the shoulders slightly away from the camera are smaller. When taking close-ups of portraits, it is more appropriate to choose 50mm and 85mm portrait lenses, which are in line with the standard focal length of the contents.

4. Why does the color of my photo feel strange?

There may be two problems with the strange tone: one is the incorrect white balance setting, and the other is the improper choice of photo style.

Suppose you take a still life indoors and choose tungsten lamp as the white balance, then this photo should be taken in this color anyway.

5. Why does my photo look like a lot of particles?

There are many particles in the photo, mostly caused by ISO sensitivity. This particle is actually called noise. This is a side effect caused by the high sensitivity and strong light amplification ability of the camera photosensitive element. The higher the sensitivity, the more noise there is in the photo. It is generally recommended that Quan Huafu set the sensitivity range to 100-6400, and half frame set the sensitivity range to 100-3200.

6. Why does my photo look hard? Not as beautiful as others?

The light is very hard, either the shooting time is wrong or the shooting accessories are wrong. The midday sun is usually very strong. If you want to shoot soft light, you can choose from 7 am to 9 am and 4 pm to 6 pm. In addition, it may be that there is no soft light box, soft cloth, etc. when using lamps. Hard light hits the face of the character directly. All people who shoot indoors can add accessories to the lamps to make the light softer.
