HDR, one of the new words associated with the digital era in photography, is defined as “image with an extended dynamic range” (high dynamic range image / photo) and is associated with the characteristics of photography and photo printing. This phenomenon is based on the fact that the human eye sees much more shades than any modern printing device or monitor can display – while, however, they forget about stereo vision and the adaptive features of the human eye, but these factors are usually discounted as more difficult for today’s technology.
Meanwhile, modern digital cameras are only capable of this to a limited extent: with all the abundance of shades that can be simultaneously captured by the matrix, modern exposure meters and optical systems are not able to set different exposure parameters for light and dark areas of the frame (for example, sky and earth at sunset ), which is why dark areas tend to come out underexposed and light areas usually come out overexposed. Naturally, it all depends on a bunch of factors, but the picture as a whole is clear. The sky is light, the earth is dark – as a result, details are lost both here and there.
A reservation should be made here: modern cameras and videography services nyc are very good, and the great photo artists have never been bothered by the illuminated sky, nor the loss of details in the shadows – they created masterpieces. However, the new time brings new requirements and requests: I want, as always, to catch two birds with one stone: work out the shadows in detail and make sure that the clouds around the sun do not light up (since we are not talents, we will at least observe the technique … maybe someone will notice).
I must say that over the years that have passed since the original publication of this article on the site, photographic equipment has stepped forward a little, and a number of cameras today can even shoot video with “double ISO”, which leads to the correct exposure of light areas due to the low sensitivity of some pixels and high sensitivity of others. The result is a rather gray picture, which is only suitable for HLG (Hybrid Logarithmic Color Gamut) displays and dense post-processing, but even now this is still just the beginnings of future technologies.
