In this world of technology the thumb rule is generally used. Meaning more the pixels greater is the image quality. While many researchers say that 8k will revolutionize television some argue that transferring from 4k to 8k might bring some challenges. This article will tell you all you know about 8k innovation
4K and 8k
4k and 8k generally mean the number of pixels that are present in the horizontal screen. For instance, consider a movie screen. Now, 4k here means 4,096 pixels and 8k would double that amount which means 8,192 pixels. So one might think that 8k resolution means twice as good as 4k but according to some researchers, this is not the case.
Authors like Routhier debate the fact that 8k is useful in delivering static shots but this can also have a negative effect and close-ups on shorts. Furthermore, Routhier says that increasing the resolution will only be helpful in covering the blur. Meaning the images will not be clear to the viewer. This is because 8k innovation will operate at 240 framer per second which is 10 times more than the basic frame per second. Hence most of the shots in television will be blurry and users won’t benefit much from 8k. Thus some of the issues of 8k innovation can be stated as follows
⦁ Motion blur
⦁ Too much detail in the close-ups
⦁ When watching a movie it can make the actors and actress have wrinkles and blemishes which can be very unflattering at times
Features of 8k innovation
⦁ Use of 33million pixels(7680×4320)
⦁ 16 times more than full HD
⦁ 4 times more than 4UHD
⦁ Ability to correct brightness automatically
⦁ Overcoming dizziness
Befits of 8k innovation
1. Sharpness is not resolution
Most of the people think that sharpness and resolution are the same. In reality, it is not true. According to researchers, more pixels would mean improved image quality. Furthermore, these researchers state that more pixels don’t mean more sharpness. So you might think if more pixels does not more mean sharpness then what does it actually do? Higher resolution makes use of its sensors to curve down the images smoothly. These sensors able to align dimensionally with the images which make the images more lifelike

2. Human point of view for 4k
Most of the people say that the human eye is not able to detect images which are less than one arc minute. Researchers like Saaski have a different opinion. According to him, our brain is made in such a way that it can see very small bits of information. Meaning our brain has the ability of hyperacuity. This ability provides the human eye with more depth and realism.

Better colors with more pixels
Curved lines are made smooth by higher pixels. Similarly more pixels would mean gradient shifts, subtle color and more depth to images. This means more realistic colouring and lifelike images. From the image above it is clear it is clear that the hue changes are from the top to bottom and front and back.
