Five reasons why the photos in the room are not sharp enough

1. Whether the ISO value is set too high

The best way to increase the ISO value is to take photos that were never taken without the need to turn on the flashlight, or set the shutter speed faster. However, it is worth noting that the improvement of ISO will lead to missing details and increased noise. Therefore, the lowest sensitivity value set by the camera should be used to obtain detailed pictures.

2. Shutter speed is not fast enough

The longer the shutter is enabled, the more light the camera enters, and the more likely it is to cause jitter and blur. Jitter blur occurs not only when you take a fast moving object, but also when the handheld camera is shaking, it will inevitably be reflected on the photosensitive element. Therefore, either use a tripod or increase the ISO value to increase the shutter speed. The anti-shake function of the lens will play a certain role, but it should be clear that the effect is always limited.

3. Insufficient light

This is for those who are still dependent on the automatic mode and do not feel the powerful manipulation and joy of the full manual mode. In the automatic mode, if the camera detects insufficient light, the shutter speed will be reduced and the sensitivity will be increased. This will cause the above two situations. In some cases, the camera's built-in flash will pop up-this is a light that almost all photographers hate.

4. Insufficient skill in the future

Many beginners hope to use photoshop in the future to make up for the shortcomings of the preliminary technology. Obviously, I still don't know how to adjust a waste slice. Moderate post-adjustment will improve the image quality, but beginners tend to pile up all the post-technical skills they know, regardless of whether the image becomes unnatural and the image quality drops. If RAW is used for shooting, the room for later adjustments will be slightly larger. There is no doubt that poor image quality will be caused by improper future adjustments.

5. Incorrect focus

The focus issue is that many professional photographers cannot solve the problem. In a low-light environment, even the most advanced digital camera, it is easy to tell right or wrong. This is limited by the technology of digital cameras, but sometimes the AF auto focus system will find the focus for a slightly moving camera. The best way is to use a flashlight to light up the object to be taken. After the focus is accurate, lock the focus and take a photo. If this is not the case, the film may be blurred.
