Choosing these professional monitors will get twice the result with half the effort in the later stage of photography.

For professional photographers, besides cameras and lenses, the equipment most closely related to photography is the display. For photographers, a professional monitor is very important in photo post-processing and video editing. This kind of display is not only extremely accurate in color performance, but also rich in external data interfaces, which can meet the needs of connecting and displaying various devices.

For photographers, a monitor with accurate color display is also very important. In the post-processing of photos, accurate color display can accurately restore the color of photos, and when using Photoshop and other software to adjust photos, all color operation feedback can be accurately conveyed, which is very important for the later photography.

So, how to choose a professional photography post-exhibition that suits you? Presumably, many readers will have such questions. When choosing a monitor, they are always confused when faced with various parameters and indicators.

Choose a qualified professional photography post-monitoring, mainly about the following points.

1, IPS screen

2. The color gamut should cover at least 99% of sRGB.

3. The color depth should not be less than 8 digits.

4. The value of color scale δE should be less than or equal to 2.

5. Screen size and resolution

6. Rich interface

Display panel material

At present, the displays on the market mainly adopt three kinds of screen panels: TN, VA and IPS.

TN screen: a good choice for quick response and competitive games. On the other hand, the display with TN screen has a small viewing angle and poor display color performance.

VA screen: The contrast of black scene is high and the display is purer, but the response speed of VA screen is slow and the screen power consumption is high.

IPS screen: Most monitors are equipped with screens with wide viewing angle and accurate color display, which is the first choice for monitors in the later stage of photography.

Therefore, IPS screen is the first choice when choosing the display in the later stage of photography, and the other two types of screens need not be considered.

Color range

Color gamut, also known as color space, is the range of colors that a display can present. Theoretically, the wider the color gamut of the display, the better. Generally, the color gamut of the display after taking photos will basically cover 100% of sRGB color gamut and more than 97% of Adobe RGB color gamut. Some new monitors not only support SRGB and Adobe RGB, but also support P3, DCI-P3, Rec.709 and so on.

Generally speaking, the color coverage is Adobe RGB P3 SRGB >: Rec.709 The photos in RAW format in the camera are in Adobe RGB color gamut mode. In order to avoid losing the color of camera photos during later retouching, professional photographic displays must cover Adobe RGB color gamut.

color depth

Color depth can also be called color depth, and the number of colors in a digital image is represented by the number of digits. Color depth is a very professional technology, so I don't need to elaborate too much theoretical knowledge here. Just know the color depth. The finer the color transition, the less likely it is to produce color cast. Therefore, the minimum color depth requirement for the display in the later stage of photography is 8 bit, and some advanced professional displays can reach 10 bit color depth.

Color standard (Delta-E)

Delta-E( E) value is an index to measure the accuracy of color. The smaller the Delta-E value, the higher the color accuracy. Generally speaking, it is acceptable to change the Delta-E value of the display between 3 and 6. If the value is lower than 3.0, the human eye can hardly distinguish the difference, and it is usually considered to be the same color. Therefore, in order to make the color of the photo displayed on the display consistent with the photo taken by the photographer, the Delta-E of the display should be less than 3. Professional photographers with high color requirements will require the Delta-E value of the display to be 2.

Does the monitor choose 2K resolution or 4K resolution after taking pictures?

When processing photos in the later stage of photography, it is often necessary to enlarge the photos to see and refine the details. If the screen definition is not enough, it will affect the quality of later retouching. Therefore, as a display used in the later stage of photography, the resolution must be considered.

At present, the size of the post-exhibition of mainstream professional photography is mostly 24 or 27 inches, and the resolution is 1080P, 2K, 4K, etc. Resolution represents the accuracy of the screen image and refers to the number of pixels that the display can display. High resolution can not only bring a clearer picture, but also bring more room for operation.

However, the higher the resolution of the display, the better. For example, the resolution of a 24-inch monitor is 1080P to 2K. If the resolution is too high, the icons and text will be too small and look laborious. For monitors of 27 inches and above, 2K to 4K resolution is more suitable.

Finally, choose the size and resolution of the display after photography, or choose according to the use environment and economic situation.

Rich interface

As a professional post-photography monitor, it is essential to equip SD card slot. Photographers can directly insert the SD card into the monitor to read and browse photos, and the workflow will be more efficient and convenient.

Apple's MacBook Pro computer is favored by many photographers and photographers because of its good color expression. The display with USB-C interface can be directly connected to MacBook Pro, which can not only provide display signals, but also supply power to MacBook Pro through the display, thus avoiding the trouble of switching.

Well, having said so many parameters of professional monitors, I would like to recommend some post-photography monitors commonly used by photographers.
