When it comes to displays, there are two main types of contrast: dynamic and true. While both have their benefits, they are actually quite different from each other. In this post, we’ll take a closer look at the difference between dynamic contrast and true contrast, and discuss when each is most appropriate.
What is Dynamic Contrast?
Dynamic contrast is a technique that is often used in photography and film to create an image that is more visually striking. The basic idea is to use two different tones or colors that are in stark contrast to each other. This can be done by using a light source and a dark background, or by using two different colors that have high contrast. Dynamic contrast can also be created by using different textures or patterns.
For example, a photographer might use a rough texture for the background and a smooth texture for the foreground. By using these contrasting elements, the photographer can create an image that is more eye-catching and memorable.
What is True Contrast?
- True Contrast is a measure of the range of brightness that a display can produce. It is calculated by subtracting the darkest black level from the brightest white level. The higher the number, the greater the range of brightness that the display is capable of producing. True Contrast is important because it allows viewers to see details in both the shadows and highlights of an image.
- A display with high True Contrast will be able to reproduce both very dark and very bright scenes without washing out the details in either one. displays with low True Contrast, on the other hand, will have difficulty reproducing both very dark and very bright scenes, resulting in lost detail in both extremes.
- True Contrast is especially important for HDR content, which often has both very dark and very bright scenes. When choosing a display, look for one with high True Contrast to ensure that you’ll be able to see all the details in both the shadows and highlights of your favorite HDR content.
Difference between Dynamic Contrast and True Contrast
- Dynamic contrast is the difference in luminance between the darkest and lightest areas of an image. True contrast, on the other hand, is the overall range of brightness levels that an image can contain. Dynamic contrast ratio is a measure of how big the difference is between the darkest and lightest areas of an image, while true contrast ratio is a measure of the overall range of brightness levels that an image can contain.
- Dynamic contrast ratio is often quoted by manufacturers as a specification for their displays, while true contrast ratio is not. Dynamic contrast ratio is a more relevant measure of display performance than true contrast ratio because it takes into account the fact that human vision is more sensitive to changes in brightness at low light levels than at high light levels.
- The true contrast ratio, on the other hand, does not take this into account. Dynamic contrast ratio is a more accurate measure of display performance because it takes into account the fact that human vision is more sensitive to changes in brightness at low light levels than at high light levels. The true contrast ratio does not take this into account. Dynamic contrast ratios are usually quoted as a percentage, while true contrast ratios are usually quoted as a number.
Dynamic contrast is the difference between the luminance of an object and its surrounding area. True contrast, on the other hand, is determined by how well two colors complement each other. In order to create a sense of true contrast in your designs, it’s important to choose colors that have enough difference in hue (or color) value. For example, blue and orange are considered contrasting colors because they have a wide range of values from light to dark. When used together, they can create a visually stimulating design with high levels of true contrast.
