HDR Photography - a Primer

Real Estate Agent with Page Taft Real Living

I recently joined a local camera club (Connecticut Valley Camera Club) and heard a brief discussion about High Dynamic Range imaging (HDR).  The speaker was talking about using this technique to eliminate the light glare that typically occurs when you are shooting a picture inside on a bright day and the outside light forces the camera sensor to under-expose the room resulting in a very dark interior.

This is an inside photo that illustrates the difference between a normal "auto-exposure" and an HDR process photo:

 "Normal" Interior Photo - note dark interior

 This technique also works with exterior photos as can be seen below (note washed out sky and bright washed out area on left side):

To learn more about HDR photography, just go to the HDR Photography Group on Active Rain - there's lots of good articles there to provide you with more insight into this remarkable technique.

Tip:  you need a camera that can easily make multiple exposures (typically -1, zero and +1 stops or more) and a TRIPOD IS A MUST. 

Then you will need a computer software program that can process the photos.  There are several available - I've used Photomatix available from HDRsoft at this web site: http://www.hdrsoft.com/ (approx. $99.00)

Check out their web site and let me know if you are impressed!

Hi Edward,

Your 'normal' shots are actually very well done, and you could get the same effect just by tweaking them a little. But I like good HDR too. Thank you for sharing.

Ed, I thought the first picture looked great until I continued to scroll down to the HDR picture, WOW what a difference.
