Single shot HDR

Tags : 

It is not always possible performing 3 or more shots to make a HDR. When we take photos of people or objects in motion, the fusion of images obtained in the HDR would be blurred and not detailed. In these cases, if we want to process this picture like an HDR, we have to take our shot in RAW mode. So open your RAW file in Photoshop with Camera Raw.

To do a single shot HDR, we need to create 3 separate images that you can merge adjusting the exposures and saving the three photos with different names:

First image:

[/lightbox]

The first image we will get is the standard one. Place the exposure to get the right amount of light and save the image to TIF.

Second image:

The second image will be our under exposure. So we have to lower the exposure to 2 stops. Looking at this picture to get the maximum detail in the highlights. After this, save the image to TIF.

Third image:

[lightbox link=”http://www.giuseppesapori.com/wp13/wp-content/uploads/2011/10/Immagine3.jpg” title=”Over exposure”]


[/lightbox]

The third image will be our over exposure. Raise the exposure of two stops, looking at this picture to get the maximum detail in the shadows. This step is complete, save the image to TIF. Now we have the three photos that we can merge in Photomatix and process the image with tone mapping.

Remember that getting a single shot HDR  remains a second choice rather than standard HDR cause the result image will loose part of the dynamic range that distinguishes this type of photography. However this process is always a very good  way for all those times that we have not available    choice when we don’t have a tripod or we take photos of people and moving objects.
