Grab a SLR job? It turns out that mobile phones can also shoot traffic like this.

IT 168 Evaluation of shutter long exposure shooting has always been the exclusive photography skill of the camera. By controlling the shutter time, we can shoot some special effects that the human eye can't capture. About two years ago, the long exposure function was moved to the mobile phone, so the mobile phone began to play this shooting technique. Before, we did a content about long-exposure spray painting of mobile phones, "Recording naked flames and teaching you to shoot invincible hot wheels with your mobile phone". This time, for a change, try to draw traffic with long exposure on your mobile phone.

We have a whim to use mobile phones to expose traffic for a long time, mainly because of a function of a recent mobile phone: P8 launched by Huawei has streamer shutter function, which integrates several modes such as traffic, graffiti, silk flowing water and gorgeous star orbit. Of course, the function is not enough. Does it work? Is the effect quality reliable? Is it comparable to a camera? With these questions, we started this shooting task.

On the control of long exposure traffic with Huawei P8 and SLR cameras-

Mobile phone: There's really nothing to say. Just fix the phone on the tripod, then select the flow function and press the shoot button, and the effect will be the same as in the video. What you see is what you get. Whether the traffic is crowded or sparse depends entirely on when you press the stop button.

▲ The long exposure shooting of the camera still needs some experience and skills.

SLR camera: First, fix it on a tripod. To ensure the best picture quality, please choose ISO 50/ lossless RAW file format. At the same time, in order to ensure fine exposure, M mode is selected, and the lens aperture is adjusted to F 1 1 (which is not too small to generate diffraction and is within the range of optimal imaging), and the shutter time is adjusted to 15s according to the instructions of the exposure meter.

▲ The camera is black during long exposure shooting, while Huawei P8 is instantly visible.

Summary: Obviously, the mobile phone is obviously more convenient than the SLR camera in the control experience of shooting long exposure flow. Although the camera is fixed with a tripod, the setting of SLR camera depends more on the photographer's experience. As a representative of mobile phones, Huawei P8' s WYSIWYG control experience allows ordinary users to easily shoot the traffic effects they want.

Comparison of proofs between SLR camera and Huawei P8-

▲ Huawei P8

▲ Nikon D800

▲ Huawei P8 on the left and Nikon D800 on the right.

The same boot time and the same angle, these two sets of proofs can see the difference in image quality and sensitivity between mobile phone and camera at once. In particular, the bridge deck will shake slightly due to the passage of traffic, which will have a certain impact on the image quality of the mobile phone, and the camera can maintain a good picture purity.

In the same place, the same shooting start time and the absolutely stable ground, the flow effect of Huawei P8 will be much better than before, and the purity and clarity of the picture will be obviously improved. Of course, there is still a gap between the overall picture quality and SLR cameras, but from a cool point of view, Huawei P8, as the representative of mobile phones, even surpassed Nikon D800 of SLR cameras.

Experience sharing of Huawei P8 shooting traffic effect-

▲ Long exposure time is too long, resulting in overexposure of vehicle streamline.

1. The long exposure time should not be too long, and the number of cars passing through each lane should be controlled at about 2, otherwise the traffic streamline will be overexposed (as shown above). According to the traffic volume of busy sections in first-tier cities, the exposure time should not exceed 10 second, and 5-8 seconds is appropriate.

2. Before pressing the shoot button, it's best to click the middle of the screen before focusing, otherwise there may be inaccurate focusing, that is, paste (as shown above).

3. Just keep ISO automatic. In busy mode, P8 will automatically keep the lowest ISO-64, and manually it can only be set to the lowest ISO- 100. Low ISO helps to control the overexposure of traffic lights.

Summary of the mutual advantages of mobile phones and SLR cameras-

Advantages of mobile phones:

1. portability-when you pass an excellent shooting environment and opportunity, take out your mobile phone in your trouser pocket and find a corner that you can rely on firmly to shoot.

2. Ease of use-Take Huawei P8 as an example, the process of shooting traffic has achieved the effect of what you see is what you get, without any setting.

3. Interactivity-In terms of interactivity, mobile phones have always had the incomparable advantages of cameras, and can be shared on any social platform after shooting.

Advantages of SLR cameras:

1. Control-allows the photographer to control the whole shooting process, including ISO, shutter time, aperture, shooting format and other factors, and get a self-styled picture.

2. Post-processing space-the camera can provide RAW digital format files, and the tolerance of RAW files of full-frame cameras can greatly increase the post-processing space.

3. Image quality-the inherent advantage of SLR, whether it is image quality, visual field or sensitivity control. In addition, when the shooting picture needs to be printed on a large scale, SLR is still the best choice at present.
