In-Camera HDR Detailed Tutorial - How to create High Dynamic Range images

This video explains into depth how to create a photograph that offers an increase in the dynamic range (or higher dynamic range) that is done by using your camera's Multiple Exposure alone rather than using Photomatix HDR (High Dynamic Range) photographic image software, which usually result in unusable garbage due to lack of knowledge in tone mapping.

Since doing this in-camera offers realistic higher dynamic range than garbage results coming from Photomatix.

No, you cannot use Auto Exposure Bracketing while Multiple Exposure because with AEB enabled, the Multiple Exposure will be disabled. Enjoy.



Multiple Exposure supported camera models:
• D3-Series
• D2-Series
• D700
• D300 / D300s
• D200
• D7000
• D90
• D80

Camera models that do not support Multiple Exposure:
• D1-Series
• D100
• D3000
• D3100
• D5000
• D70 / D70s
• D60
• D50
• D40X
• D40

Photo retouching: Make HDR (High Dynamic Range) pictures - HDR Tutorial

HDR technique enhances details in a picture and allows achieving truly unique results. It can be carefully used in order to produce most natural results, while a heavier processing would lead to more particular creative results.

Tools
The software tools needed to produce HDR images are a RAW file processor (Photoshop is ok), and an HDR specific software, the most famous one is PhotoMatix.

How to shoot the pictures
There are two ways to get source pictures for an HDR processing.The first one relies on the AEB (Automatic Exposure Bracketing) function of the camera: it allows setting the camera to automatically shoot three pictures of the same subject, each with a different exposure level.
The second one requires a single RAW shot, which will be used to produce three or more images during the post-processing phase.

Tutorial HDR Photography - How to realize HDR photographies

High Dynamic Range, technichally speaking, means achieving as a result a very wide dynamic range, exceeding the physiscal limits of the sensor, thanks to the possibilty of easily combine digital pictures each having exposure settings optimized for the different areas of the scene.

From this definition follows that it is impossible to achieve a true HDR picture from a single shot, because a single shot has a dynamic range inside the sensor's limits.
The HDR technique has some limitations, as all techniques, the main one is that it can only be applied to static subjects and scenes, with the camera mounted on a tripod.
Sometimes the term HDR is referred not to a photo-editing technique, but to pictures showing very saturated colors, high contrast and diffused brightness allover the image, whose can be obtained from a single shot with some post-production job. But this is not a true HDR in the sense we meant in this paper, it is just post-production.
The main characteristic of a true HDR picture is a very wide dynamic range, wider than the sensor can phisically capture, and therefore with "opened" shadows and "limited" highlights even when the contrast is high, in those situations where a sensor would tipically close shadows and/or burn highlights. Situations where a single shot (whatever the RAW file is processed) cannot contains complete information. Therefore, it is obvious that it is impossible to get HDR images from a single RAW file.
