1 High Dynamic Range Photography How to create an HDR Photo video

2 The Problem Here's the problem in a nutshell: Real-world scenes contain light ranges that exceed a 50,000:1 dynamic range. For over a thousand years, media has been limited to around a 300:1 dynamic range. So you have a mapping issue: how do you represent light values in a scene using a much more limited set of light values for a particular media? The answer – “Tone mapping” = Using the best light information from not one but a variety of photographs, combining them into one perfect ambient lighting photo!

3 A Light meter is a device used to measure the amount of light. In photography, a light meter is often used to determine the proper exposure for a photograph.light photographyexposure The exposure has a meter reading which can be changed manually to acquire an under or over exposed photograph.

Clouds Water Flags Trees and plants in wind (means nearly always ☺)
