Understand these 18 questions about mobile photography, no matter whether you take photos or videos, the effect is more professional (Part 1) Continue to share the remaining 9 questions from the above.

10. How to choose the photography style in the mobile phone?

There are 5 photography styles in iphone13promax, "standard, high contrast, high saturation, warm tone, cool tone". The iphone photography style is different from the filter functions in other mobile phones. The photography style algorithm will run directly during the imaging process. The AI ​​algorithm can intelligently identify various elements in the image and avoid inappropriate color changes. The filter effect will be more natural. The photography style function can basically meet the shooting needs of ordinary users to adjust the color temperature in specific scenes, eliminating the trouble of post-processing. Open the phone's "Settings - Camera" to find the "Photography Style", swipe left and right to choose a different effect of the photography style.

11. How to choose a mobile phone tripod?

Don't feel troublesome, whether you are taking photos or videos, a tripod is indispensable, and it can't be too much work. For example, I do not approve of the simple shelf on the left side of the picture above. It is barely usable indoors, but it is more troublesome to use outdoors. If the ground is uneven or there is a slight breeze, the stability will become poor. I use a camera tripod (the right side of the picture above), which has a foldable structure and is highly portable. It is enough to add a metal phone clip (pictured below) with the same base as the quick release plate. Just think, when shooting long exposures or time-lapse photography, even a little bit of jitter can ruin your work, right? So stability is the most critical performance of a tripod.

12. What is the closest focusing distance of the lens?

If the object is too close to the eye, we can't see clearly, right. The same is true of the lens, too close to the subject will not be in focus. Each lens has its own minimum focusing distance, which is simply the closest shooting distance at which the lens can focus when it is close to the subject. If you want to shoot good works, you must first understand the equipment in your hand. No matter how many lenses your phone has, you should know the closest focusing distance of each lens. I'll sell it, and it's a little homework for everyone. Test the closest focusing distance of your phone's lens, and then send it to the message area. Format: XX mobile phone, wide-angle lens (/ultra wide-angle lens/telephoto lens), the closest focusing distance is XX cm. Since the mobile phone is relatively thin, the closest focusing distance ≈ the working distance, you can measure the closest shooting distance that can focus between the mobile phone and the subject.

13. Is a telephoto lens really only suitable for shooting distant scenery?

It is true that a telephoto lens can make people or scenes in the distance very large, but this is only the most basic usage. In the hands of professionals, telephoto lenses are more used to express perspective compression effects and close-up close-ups. The image above is a screenshot of a frame from a video I shot, and this is what I shot with a triple telephoto lens. Some people may say "you can also use a wide-angle or ultra-wide-angle lens to shoot this picture", wrong! Because wide-angle and ultra-wide-angle lenses take pictures at close range, there will be a lot of distortion.

14. Do multi-lens phones still need external lenses and filters?

Required. Although most mobile phones are now multi-lens, some external lenses and filters are still irreplaceable. For example, the macro lens, the picture below is the effect I shot with an external macro lens. Although many mobile phones have a macro shooting function, the effect is still very different from that of a professional external macro lens. Then there is the polarizer, which can adjust the reflection effect of non-metallic surface objects. Such as glass, water, sky, plants, etc., we can strengthen or weaken the reflection effect according to the needs of shooting.

15. Why is the audio and video of the interview video I shot out of sync?

This question has been heard by many people, but I have not encountered it, so the answer I gave is for your reference only. There are many reasons that cause the audio and video to be out of sync. As far as the shooting is concerned, I guess it is a problem with the computing power of the mobile phone. If the video you shoot has audio and video out of sync, you can consider reducing the frame rate. If you used 60fps before, you can try 30fps next time.

16. Why should I choose low pixel or low resolution to take photos or videos in low light environment?

At least don't choose high resolution or high resolution. Because the area of ​​the image sensor (cmos) has not changed, increasing the number of pixels means that a single pixel becomes smaller, and the absorption of light will naturally become worse. On the contrary, choosing a low pixel or low resolution can absorb more light, and the noise in the picture will naturally be reduced, thereby improving the picture quality.

17. How to lock the exposure without locking the focus when shooting video with an iPhone?

Most of the videos we shoot are to lock the focus and exposure values, but some scenes only need to lock the exposure. For example, we take a picture of a person walking by from a fixed camera. If the focus and exposure are locked, then the person will only be clear at the position you locked, and the closer he is to the lens, the more blurred he will be. At this time, we only need to lock the exposure, and let the mobile phone automatically adjust the focus. I take iphone13promax as an example, the specific operation is as follows: open the video shooting interface of the mobile phone (horizontal screen), click the icon of the adjustment slider in the lower left corner (in the red circle in the above picture), and then there will be an exposure adjustment icon on the right side of the screen. slider. We adjust a proper exposure as needed, and then press the shutter to shoot. The phone will automatically recognize the person in the screen and adjust the focus at any time. In this way, a clear effect can be achieved when the characters are walking. The exposure adjusted in this way is locked, so there is no need to worry about the flickering of the screen due to changes in the amount of incoming light.

18. Why does the picture quality deteriorate after slowing down the speed of video editing, and are there any countermeasures?

The frame rate of most movies is 24fps, which means that the static images of more than 24 frames per second are played, and to the naked eye, they appear to be continuous and unstuck dynamic images. Suppose you shoot a video at 60fps, and the speed is doubled to 30fps, which is acceptable. But if you continue to slow down, when the frame rate falls below 24fps, the picture may freeze. If you use clipping to edit mobile phone video, when slowing down, you must remember to select "Smart Frame Compensation", and then click "√" to confirm, so that it will not be stuck.
