There has been a breakthrough in LCD TVS recently. The Samsung LN-T4681F (AVAILABLE ALSO IN 40" AND 52") has a contrast ration of 500,000:1. Impressive. Sony also has an OLED TV with a contrast ratio of 1,000,000:1. When you get to 500,000 you see an almost perfect black. If you have a movie and the screen is black, you might think that the TV is off. When you see the 1,000,000: TV you definitely think it is off. the eye can detect any contrast ratio pretty much. But i think you mean what is the ratio when your eye simply sees black. and that is when you get beyond 500,000:1. It doesn't really get much darker and blacker than that.

What contrast ratio can the Human eye perceive?
The human eye, at any particular instant, can perceive contrast ratio over a range of 400:1 to 10,000:1 according to numerous references. However, the human eye is a dynamic organ and can adjust, both chemically and via iris movement, over some 30 minutes in steady light conditions to perceive higher contrast ratios of up to between 1,000,000:1and 10,000,000:1. One can think of the eye as an adaptive detector. Age is a factor influencing what contrast ratio might be perceived by the particular individual. The images displayed can affect the perceived contrast ratio with the human eye being able to detect higher contrast ratios for static images as opposed to moving images. Ambient Light Conditions Even small amounts of ambient light (one LUX - a candle flame) significantly reduces the ability of display devices to render higher contrast ratios (in the 1,000's). A black area can only be as black as whatever incident light is reflecting from it. You cannot "project" the color black. Doubly detrimental is the rapid drop off of the eyes contrast sensitivity with higher ambient light levels. Spatial Frequency The eye is sensitive to the spatial frequency which is a factor related to the distance between the contrasting image elements in relation to each degree of field of vision at the eye. Consider that the frequency is the count of the number of alternating vertical stripes of black and white across an arc of one degree with the eye as its origin. Increasing the number of vertical stripes across the arc (making them thinner) will, beyond a certain point, reduce the eyes ability to perceive contrast ratio - even though the actual contrast between the white and black stripes remains the same. For a practical demonstration of this concept try this dynamic demonstration of the eyes variation in contrast sensitivity with spatial resolution by the USD Internet Psychology Laboratory. Differences in contrast ratios in the multi-thousands should only be a consideration in choosing between display devices when you are going to place them in a strictly controlled, very low ambient light environment - something like a windowless home theatre room with dark finishes on all walls and surfaces. For higher ambient light viewing environments brightness should be a much higher rated selection criteria than contrast ratio. There is no substitute for judging between the image quality of displays than viewing them side by side with your own eyes in a viewing environment with an ambient light level similar to where they would be located.
How many stops of dynamic range does the human eye have?
The human eye can perceive about 20 stops of dynamic range.
What is a Dynamic line in art?
A dynamic line in art refers to a line that conveys movement, energy, or tension, often guiding the viewer's eye through a composition. These lines can be curvilinear or angular and are typically used to create a sense of action or emotional intensity. Dynamic lines contrast with static lines, which tend to evoke stability and calmness. Artists often utilize dynamic lines to enhance the overall expressiveness of their work and to engage the audience more actively.
How does contrast work?
Contrast is the difference between elements in a design, such as colors, shapes, or textures, that helps create visual interest and hierarchy. By using contrasting elements, designers can make certain parts of a design stand out and grab the viewer's attention. This technique can help to organize information, guide the viewer's eye, and create a dynamic composition.

What are the best tips for using a fish eye lens for phone photography?
When using a fish eye lens for phone photography, make sure to center your subject for a more dynamic effect. Experiment with different angles and perspectives to create unique and interesting shots. Avoid using the lens in bright sunlight to prevent lens flare, and consider editing your photos to enhance colors and contrast.

When is it appropriate to use metallic photo paper for printing photographs?
Metallic photo paper is best used for printing photographs when you want to enhance the vibrancy and depth of colors in the image. This type of paper is particularly suitable for images with high contrast and rich colors, as it can make them appear more dynamic and eye-catching.
