Isn t it all very slow to capture with cameras?

The fastest focus is focus-free, which is the so-called superfocal focus followed by manual focusing, which is an empirical problem and cannot be practiced quickly. The slowest is autofocus, and of course, modern digital cameras can also achieve autofocus in about one to two seconds.

The fastest metering is metering-free, which is actually easy to understand, you enter a scene and immediately set it manually according to the situation of the scene, don't measure the light every shot, it must be very fast. Of course, the premise is that you are familiar with manual operation, and this is enough with a little contact and a little experience.

As for the second floor, it is basically impossible to finish things in 0:00 seconds under the automatic situation. In fact, the computer is very stupid and very unreasonable, whether it can be almost the main thing is still up to people. At the beginning of the 20th century, the famous documentary master Bresson had a large number of captured works, not to mention autofocus and autometering, and even computers did not exist at that time.

This can be adjusted, and now the autofocus of the digital camera must be relatively slow, plus the ** time is a little longer, it is even slower.

Where the light is good, manually adjust the focus, then the shutter can be set shorter, so that it is fast.

If the light is not good, then you need a wide aperture, and a longer ** time, if it is autofocus again, then the time is a little longer.

To put it simply, the time of the fully automatic digital camera will be a little longer, and the fully manual, if the focal length has been adjusted, the shutter time will be adjusted by itself, which can be long or short, but too short The image quality is not necessarily good.

I'm sorry to hit you, I've only seen a few kittens, and I think the tigers in the world are so big?

Also, if used properly, the shutter lag of the current card machine is not more than half a second, and the technical relationship with the user is not small, professional sports cameras, the shutter lag is tens of milliseconds, and you can shoot more than ten shots in a second Good lighting conditions Focus can be completed in an instant when you press the shutter halfway.

Strongly require a DSLR, so fast that you have nothing to say, from focusing to completing the shooting, a few tenths of a second is enough.

PS The ones you use are all small digits, and you are embarrassed to take them out in front of a high-end camera.

Generally, the camera reflects slowly, and there are the following situations:

1. The camera shutter time is long, which is obviously slow reaction time; In low light, the camera will automatically increase the shutter time to increase the amount. If you want the camera to be faster, you need to reduce the shutter time, but in order to ensure the amount of **, you have to increase the ISO, or increase the aperture, or increase the **compensation.

Or add a flash.

Second, the camera pixel setting is large, the compression ratio is small, and the camera processor processing time is relatively long; The higher the camera pixels, the smaller the compression ratio, and the larger the memory occupied by the photo, the longer the camera's processing time, from broadcast to broadcast to memory card.

It will take time. If this time is too long, reduce the number of pixels captured by the camera accordingly. Generally, 300-500w pixels can be used for family souvenirs, and the quality is medium.

3. The camera memory card is slow; Today's high-resolution cameras need to be equipped with high-speed cards to keep up with the need for high-capacity memory. SD card before.

It is a regular card, and the speed is much slower than SDHC. If you want to increase the speed of your camera, choose a high-speed SDHC memory card. Fourth, the flash recycle time increases; If you use a flash when taking photos at night or in a low-light place.

After each flash, the flash needs to be recharged, during which time the camera reacts more slowly and does not return to normal until the flash is fully charged. In this case, it is inevitable that the speed will drop, unless you use a large-capacity battery, but the battery is used very quickly in the early stage, and when the power is not sufficient, the camera using the flash has already reflected relatively slow.

5. Of course, this is the worst imagination, that is, the camera is broken.

It is mainly affected by the performance of the machine itself.

What model do you use Samsung, and how big is the memory that you bought that year, tell me, I also use Samsung, how slow is it in general? It takes a few seconds.

When the image sensor records the image, it is converted to a signal and then displayed on the LCD screen.

There's either your memory card slow.

It's hard to judge if you don't have a detailed explanation.

In fact, all digital cameras are like this, the screen is on when focusing before shooting, and then the screen is black, and the CCD CMOS data is credited to the memory card for a few seconds in between, and then, if you choose to play back each shot in the menu, the machine will automatically read the data from the memory card, process it and display it on the screen. The speed of this process depends on:

1. The read/write speed of the memory card.

2. The speed of writing and reading cards of the camera.

3. The processing speed of the camera's ** display.

4. The speed of the camera's screen brushing, 5. The cache size of the camera, such as a powerful machine for continuous shooting, its cache is very large, etc. If you want to improve the speed, it is recommended to turn off the function of playback after shooting in the menu (my camera is called playback, maybe yours is called another name), so as to save several steps of time. You can continue to take the next picture, and after a while, you can play it back and watch it one by one when you have time.

Mid-to-low-end cameras have this problem, because the manufacturer uses a non-advanced shutter and internal circuit system, and the boot speed and photo-interval of a good camera will be much faster! It's a congenital reason, or why the parameters of the camera have a boot speed! The higher ones must be a little more expensive.

If it's a high-end machine, such as a DSLR or a high-end portable phone, it will be much better!

Ask why Nikon's camera is slow to respond to taking pictures.

This one is for stability on a tripod. 2.I turned on the reflector pre-up, because my D3 was really in the left turntable.

D90 should also be there. Find it yourself. 3.

**Time is too slow, slow response is long time.

Problems with the body or too many photos are almost full of memory.

Samsung phones are generally recommended to do the following:

1.Turn your phone on and off again.

2.Go to Phone Settings - Apps - Tap Camera - Storage - Clear Data.

3.Back up your phone's data (**book, SMS messages, multi** data, etc.) and restore your phone to factory settings.

If the problem persists, it is recommended to send the phone to the nearest service center for testing.

DSLRs do not recommend using live view.

Rationale:1SLR through the reflector and then to the viewfinder is the characteristics of this camera, the viewfinder and LCD screen real-time framing are through different framing focusing systems, the design of real-time framing is only auxiliary, such as when the light is not good, the main job of the SLR is to view the lens optical framing, which is its biggest advantage;

2.The principle of real-time framing is that the reflector is pushed upwards, and the shutter is opened, so that the lens light is directly imaged on the image sensor, and then the image processing chip sends the image on the image sensor to the LCD screen, and the image sensor is powered on all the time during framing, which will increase power consumption;

3.The real-time framing speed of the SLR depends on its image processing chip, ignore this point first, when the real-time framing, the shutter should be open all the time, the shutter closes quickly after pressing the shutter control button, and then opens again according to the shooting parameters**, closes after completion**, and finally reopens and waits for the next shot, opening and closing the shutter once more than optical framing, which leads to double the shutter consumption, and secondly, the shutter lag becomes longer.
