Dynamic Photo-HDR



Many times you see a beautiful scene and of course you take a picture! The result is often far from being the magical scene you remember.


Our eyes are very adaptive and they are also more sensitive to intensity than color. The chip in camera is none of that.

It is estimated that our eye can see over a dynamic range of nearly 24 f-stops while a digital camera can capture a dynamic range around 6 to 9 f-stops at best.


The High Dynamic Range Imaging is a set of techniques that has been developed nearly 20 years ago to overcome the limitations of electronic devices by combining multiple exposures into one great looking image.


For a well light outside scene such as the one on the right we could set our digital camera to correctly capture either, but hardly both:
  • the foreground (left image) in which case the sky will become overexposed
  • the sky (right image) but the foreground will be then underexposed
Using HDR technique we can combine the different exposures to create a single image that shows details in both sky and the land.

A High Dynamic Range photography can be created by taking few photos with different exposure, then combining them in the software into a high dynamic file.

The last thing is to tone-map the HDR image so we can see it in our screen, print it, post it on the web and enjoy.


We created our software to be fun to use, fast and straight forward. No fiddling with incomprehensible parameters. And as it is common for our products we added many cool features that you may not have seen in any other package.


DPHDR has more effects than any other comparable software like the little Planet effect pictured on right.


For example it allows you to paint the Dynamic Light effect just where you want it by using brushes.

You can use only 1 file!

Our Dynamic Photo HDR (DPHDR) can be actually used with a single RAW or JPG image with very good results using Pseudo-HDR process.


Granted, this will not expand the full dynamic range, but the process itself will in fact add a very distinctive "punch" to your image that may look just like the real thing. Try it!
