WebHDR Roll-Your-Own

The following page allows you upload a series of up to 9 exposure-bracketed images onto our server where they will be processed. The results that you'll get back are:

Please see the RYO-Demo pages for an example. The back-end software running on this server is Greg Ward's hdrgen (see under Software).


In order to produce exposure bracketed images successfully, please follow the simple rules below:

  1. Know your camera. Be familiar with the Aperture Priority and Manual modes.
  2. Use a tripod or rest your camera against a fence, wall or similar.
  3. Try to avoid having objects and people moving through your scene during exposures.
  4. Make sure the brightest image in the series is not all white and the darkest one not fully black.
  5. Switch off automatic white-balancing as it could lead to incorrect results.
  6. Don't post-process the images before submitting them to WebHDR. Use the originals. Most image processing software alters or even discards the EXIF header information which is vital for the software to determine the exposure.
  7. If you would like to increase the accuracy of the results, please read up on Camera Calibration.

We are currently experiencing server problem. R-Y-O is disabled. We are looking into this. Sorry for any inconvenience.

No, this is all too much for me.
