How to shoot red rice at close range

The software optimization of Xiaomi camera is not enough. In order to achieve better results, rice noodles should work hard: click on the settings, first look at the settings interface, there are many options, here we only choose a few useful ones to focus on.

White balance: the color of the object will change due to the color of the projected light, and the photos taken under different light conditions will have different color temperatures. For example, photos taken by ordinary incandescent lamps may be yellow. Generally speaking, CCD can't automatically correct the change of light like human eyes. Therefore, through the correction of white balance, it will immediately adjust the intensity of the red, green and blue colors of the whole image according to the image characteristics of the current portrait, thus correcting the errors caused by external light.

Some rice noodles react to yellow photos, which is caused by white balance and environmental mismatch. You can choose it manually, and the landlord also chooses automatic here. If there is obvious color cast, shake the phone a few times to change the scenery and it will return to normal.

Sensitivity ISO: ISO sensitivity value is a measure of the sensitivity of traditional camera negatives to light, which is usually expressed by ISO value. The larger the value, the stronger the optical rotation. Commonly used methods are ISO 100, 400, 1600, etc. Generally speaking, the higher the sensitivity, the coarser the particles of the negative film, and the worse the magnification effect. However, digital cameras also use this ISO value to mark the metering system.

Rice flour reflects that Xiaomi has a lot of noise when taking pictures, because ISO is set to automatic by default, which should also be the focus of the next optimization of Xiaomi camera. Here, manually set ISO to the lowest value 100, and the noise of taking pictures will be obviously reduced. Of course, lowering the ISO value also has side effects, because more exposure is needed, the exposure time will be slightly extended, and it is more sensitive to jitter.

Photometric mode: Digital cameras basically adopt automatic photometry and measure through the lens. The advantage of photometry through the lens is to directly reflect the light intensity of the scene, that is, the light is projected onto the CCD through the lens, and the CCD sends the light signal to the CPU of the digital camera for analysis. The CPU will adjust the exposure value according to the reflectivity of the subject. Professional photographers will actually check their exposure value with gray cards and photometers.

This option is usually automatic. If you are used to placing the subject near the center of the picture, you can adjust it to midpoint metering or center weight metering.

Finally, contrast, sharpness and saturation:

Contrast is a measure of the different brightness levels between the brightest white and the darkest black in an image. The larger the difference range, the greater the contrast, and the smaller the difference range, the smaller the contrast.

Sharpness, sometimes called sharpness, is an index reflecting the sharpness of image plane and edge.

Saturation refers to the brightness of color, also known as the purity of color.

These three items can only be recognized and adjusted by the naked eye, and different scenes need different adjustments. On the whole, if the saturation is slightly higher, the picture will be bright and moving, the contrast and sharpness will be slightly higher, the picture will be clear and the details will be full.
