Nikon camera ISO sensitivity, camera sensitivity ISO set how much is better

ISO stands for sensitivity, and it is also the abbreviation of the International Organization for Standardization, which is also the organization that quantifies sensitivity. Sensitivity is a measure of the sensitivity of a negative to light, which is determined by sensitivity measurement and the measurement of several numerical values, and the International Organization for Standardization standard is ISO6. For less light-sensitive films, it takes longer to achieve the same imaging as the more sensitive films, so they are often referred to as slow films.

Highly sensitive negatives are therefore referred to as fast negatives. An ISO system that is closely related to sensitivity is the P>

ISO sensitivityThe sensitivity of Nikon cameras is relatively sensitive, and the more advanced the Vico configuration, the more his cold Du Yue.

The ISO sensitivity of the Nikon camera, this is different according to the beauty band of your camera, so its sensitivity is also different, the higher you buy, the better the sensitivity.

ISO sensitivityISO sensitivity: Generally speaking, the greater the ISO sensitivity, the more sensitive the camera is to light, and the shorter the shutter time will be, but there will be more noise in the image, which will affect the image quality.

The adjustment of the camera's sensitivity mainly needs to be decided according to different photographic scenes.

Let's take a look at the effect after ** according to different photography scenes.

The iOS sensitivity of the steering machine can be adjusted, and he is a very good machine.

The OS sensitivity should be very good, and it is recommended that you log in to that Nikon camera**.

1. Choose the lowest possible ISO sensitivity according to the environment for shooting, if it is not a very dark environment, it is generally best not to exceed.

2. In night shooting or shooting in an environment that requires a long time ** and needs to increase the ISO value, the noise will inevitably increase, in this case, the noise reduction function of the SLR is generally turned on to reduce the noise, or the noise of the picture is reduced through post-processing.

We know that the commonly used ISO values are generally ??10,000 and so on, the ISO value of advanced SLR cameras is higher, and the general sensitivity setting should be set according to the weather or light conditions. In general, the author sets it up like this:

3、.ISO settings for sunny days are 100-300.

4. ISO setting on rainy days: 200-400.

5. ISO setting for night scene or very dark environment: 100+ flash or artificial lighting, then use a tripod or fix the camera with a fixed object to reduce the ISO value to a lower level.

6. Scenes such as parties, concerts, and dance parties are easy to cause insufficient light, so you can use ISO800 or low value plus flash.

When you shoot in Pro mode, you can freely adjust parameters such as ISO sensitivity, focus method, and more.

2.You can set the following parameters:

Adjust the metering method: Tap M to select the metering method.

Adjust ISO sensitivity: Tap ISO and slide the ISO adjustment area.

When light is low, ISO sensitivity can be increased; When there's enough light, you can reduce the ISO sensitivity to avoid excessive noise in the image.

Adjust the shutter speed: Tap S to slide the shutter speed adjustment area.

The shutter speed will affect the amount of light entering the camera, and the shutter speed can be adjusted to a lower level when shooting still landscapes and portraits; When shooting moving landscapes and portraits, the shutter speed can be adjusted higher.

Adjust**Compensation value: Tap EV· and slide the EV adjustment area.

When the light is low, the EV value can be turned up; When the light is strong, turn down the EV value.

Adjust focus: Tap AF· to select the focus mode.

Adjust the color tone: Click WB · and select White Balance.

If in daylight, you can select the sun icon; On a cloudy or dark day, select the rain icon.

Tap the color temperature icon to change the color temperature to give the image a cooler or warmer tone.

Adjust the storage format: The Pro mode provides you with two image formats, JPG and RAW. Click on the jpg icon at the top of the viewfinder and select a different storage format.

The RAW format retains more details and is convenient for post-processing, but takes up more storage space; The jpg format** takes up relatively little storage space, so you can choose according to your needs.

If you select the RAW format, when you take a photo, the phone will automatically save a normal format and a RAW format**, and the RAW format ** will be saved in the RAW album in the gallery.

Turn on the AF Assist Light: To focus in low-light environments, tap the Focus Assist light icon to turn on the AF Assist Light.

3.Click the shutter to take a photo.

1. Turn on the Canon DSLR camera switch, as shown in the figure below.

2. The camera is set in Pro mode M gear, as shown in the figure below.

3. Find the camera settings screen on the right and find the ISO (sensitivity) level.

1. Different grades and models of cameras have different ways to set ISO. Some can be set via shortcuts, while others need to be set in the Deep Finger Simplicity menu. Some can also be set to activate Auto ISO at the lower limit of shutter speed compensity, and set an upper limit for Auto ISO.

This ensures a balance between shooting clarity and image quality.

2. Generally speaking, the lower the sensitivity, the better the image quality, so photographers are accustomed to using ISO100 to shoot films. Unless you shoot a moving subject, the ISO value will be increased when a high-speed shutter speed is required. Through experimentation, photographers can determine what the maximum tolerable ISO of a camera and pants is, to ensure that the image is less noisy, and a certain clarity is maintained after noise reduction.

It can be set to the maximum and then back to one gear, for example, the maximum value is 6400, you can set 3200. Generally, the noise of the camera is relatively high at the maximum ISO, and the noise is not noticeable when returning to one stop.

When setting the ISO, you also need to look at the intensity of the light, if the light is too strong (noon during the day), you can set it to 100; When the light is bad, set high (indoors or at night).

Don't be afraid to use a high ISO when using a camera

The lower the sensitivity setting, the more detailed the image. However, the light sensitivity is low, so it is not suitable for shooting moving or low-light objects. So how much to set depends on the subject you are photographing. When the automatic light is good, it is generally about 80 to 100.

Friend, the sensitivity ISO depends on the environment at the time of shooting, and the sensitivity in automatic mode is 800 ISOIf you're currently shooting with ambient darkness, turn up the sensitivity a bit.

ISO sensitivity is a measure of the sensitivity of a film to light, which is determined by sensitivity measurement and the measurement of several values.

ISO is achieved by adjusting the sensitivity of the sensor or merging the sensor points, that is, by improving the light sensitivity of the sensor or merging several adjacent sensor points.

Sensitivity, which is the ability to perceive light. The higher the sensitivity, the greater the ability to perceive light. For example, when the light is low indoors, you can turn the sensitivity higher to ensure that the shutter speed is not blurred due to being too slow.

In general, the higher the sensitivity, the coarser the granularity; The lower the sensitivity, the finer the granularity, that is, the higher the clarity. Therefore, when shooting portraits in the photo studio, we will try to choose low sensitivity to ensure the clarity of the details after magnification. For this reason, we try to choose a low sensitivity when taking photos with a shutter speed (faster than 1 to 60 seconds).

When using a home camera, as long as you put the shooting mode on "auto", the camera will automatically adjust the sensitivity, don't worry about it.

The use of high sensitivity is mainly used in low-light photography, especially in sports photography and photojournalism.

What is ISO?The great god of photography popularizes the sensitivity and his understanding of photography!

How to adjust the ISO: There is a function key marked with it"ISO", press and hold the plus main command dial to adjust the ISO.

The M stop is a manual setting: it means that the aperture and shutter are adjusted by the main command dial, and the aperture is adjusted by the secondary command dial.

Note: If you hold the camera in your right hand and have an adjustable dial near the big female finger, it is the main command dial, and the secondary command dial is at the index finger).

Some SLRs have ISO buttons, which can be adjusted by holding down and matching the dial. Some camera buttons are more simplified, and you need to go to the menu to find the ISO adjustment interface.

ISO is the speed of light sensitivity, and if you turn the ISO up, you will get a brighter image with the same shutter speed and the same aperture F-number. On the other hand, if you lower the ISO, you will get a darker image with the same shutter speed and the same aperture F-number.

In the case of manual mode, after adjusting the ISO value, refer to the camera's metering parameters and adjust the shutter speed and aperture according to your intentions.

Here's an example of an ISO application scenario: the light is not very good. In the case of ISO100, you shoot with a focal length of 50mm, the shutter speed is 1 10s, and the aperture is already at its maximum.

You don't have a tripod, and the hand shaking causes the picture to always be unclear. You can try adjusting the ISO to 800 and try using the maximum aperture with a shutter speed of 1 80s. You find that the brightness of the picture is the same, but because the shutter speed is faster, the picture is clearer.
