How to adjust the ISO of the camera

How to adjust the ISO sensitivity of SLR camera for me?

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

2. Set the camera to professional mode M, as shown in the figure below.

3. Find the camera setting screen on the right and find the ISO file.

Extended data:

ISO can usually set the lowest value, such as standard ISO, because the lowest ISO picture has the best effect, but the light is better where you need to take pictures. Under the same conditions, the lower ISO is 2 1 13, the darker the picture, but the better the picture quality. When the light is strong, the lowest ISO is the best choice.

The shutter speed should not be lower than 1/50 seconds, because judging from the accent, this is hand-held shooting. When the shutter is low, the hand will shake and the photo will be burnt.

When shooting in professional mode, you can freely adjust parameters such as ISO sensitivity and focus mode.

2. You can set the following parameters:

Adjust metering mode: Click _ to select metering mode.

Adjust ISO sensitivity: Click _SO to slide the ISO adjustment area.

When the light is weak, the ISO sensitivity can be improved; In the case of sufficient light, the ISO sensitivity can be reduced to avoid too much noise in the picture.

Adjust the shutter speed: Click _ to slide the shutter speed adjustment area.

Shutter speed will affect the amount of light entering the camera. When shooting static scenery and portraits, you can slow down the shutter speed. When shooting sports scenery and portraits, you can increase the shutter speed.

Adjust the exposure compensation value: click _ v to slide the EV adjustment area.

When the light is weak, the EV value can be increased; When the light is strong, reduce the EV value.

Adjust focus: click _ f to select focus mode.

Adjust hue: click _ b to select white balance.

If you are in the daytime, you can choose the sun icon; In a cloudy or gloomy environment, select the rain icon.

Click the color temperature icon to change the color temperature to make the picture look colder or warmer.

Adjust the storage format: Professional mode provides you with JPG and original image format. Click the JPG icon at the top of the viewing box and select a different storage format.

RAW format photos retain more photo details, which is convenient for post-processing, but it takes up more storage space; Photos in JPG format occupy relatively small storage space, so you can choose according to your needs.

If the RAW format is selected, the mobile phone will automatically save a photo in normal format and a photo in RAW format when taking photos, and the photos in RAW format will be saved in the RAW album of the gallery.

Turn on the auto-focus auxiliary light: To focus in low light, click the auto-focus auxiliary light icon to turn on the auto-focus auxiliary light.

3. Click the shutter to take a photo.

How do novices set ISO parameters in different situations?

If you want to know what kind of ISO value is needed under what circumstances, you must first know its influence on shooting.

First, what is the sensitivity (ISO)

ISO controls the brightness of photos. Different from aperture and shutter, shutter and aperture control the amount of light, while sensitivity is to improve the sensitivity of camera photosensitive elements. The lower the sensitivity, the darker the photo; The higher the sensitivity, the brighter the photo. However, with the increase of sensitivity, the more noise there will be in the photo, and the image quality will decline.

Second, the influence of sensitivity on shooting

Improving ISO can improve the brightness of the picture.

The larger the ISO number, the more sensitive it is to light and the higher the exposure of photos. In order to get the best imaging quality, we should use low ISO shooting as much as possible. However, if the light is not good, using low ISO will lead to slow shutter speed, and if there is no tripod, it will easily lead to blur. In order to avoid this situation, we can use high ISO shooting when necessary to make the photos clear.

Low sensitivity

2. High sensitivity will bring noise problems.

The noise is mainly due to the tiny particles produced by the electronic image sensor in the process of receiving light and converting it into electrical signals, and these particles are usually caused by electronic interference, but the main body does not.

Generally speaking, the amount of noise is also related to the length of exposure time. The longer the exposure time, the more noise. When using high sensitivity, if the exposure time is reduced accordingly, the noise will not be too serious, and many cameras have automatic noise reduction function.

Third, the ISO setting of common shooting scenes

Portrait shooting

It is best to adjust the aperture to f5.6 or more, with a small depth of field and a prominent subject. The distance should be adjusted according to the needs of bust, whole body or local close-up. In the case of sufficient light during the day, the sensitivity should be set at around 100, and the maximum should not exceed 400.

Night scene shooting

Use a tripod or put it on a fixed object (steps, stools, etc.). ). The camera uses gear (aperture priority), the white balance is set to automatic or incandescent mode, and the aperture is set to f8 or even number. ISO should be controlled within 200, and the shutter speed should be slowed down to extend the exposure time appropriately to prevent passers-by from entering the screen.

Night character shooting

Use tripod, set automatic white balance, ISO is within 100-400, gear A and aperture are around f8. Use slow synchronous flash. When the shutter is pressed, the flash flashes once and flashes again before the end of exposure. During shooting, the subject does not leave the line of sight.

How to adjust the iso of SLR camera?

Turn on the switch of the SLR camera, set the camera to professional mode M, find the camera setting screen on the right, find the ISO file, press the ISO file, and turn the handle to the corresponding ISO value, so you can easily take a clear photo. Definition and application of sensitivity ISO The so-called sensitivity refers to the ability to perceive light, that is, the ISO value. ISO values are usually ISO 100, 200, 400 or higher. Generally speaking, at low sensitivity, the picture is clearer and finer, and the details are deeper. And high sensitivity can also cope in dark environment.
