Here’s another alternative free HDR imaging software for people who want to create HDR images but can’t afford those popular but pricey Photomatix Pro 4 and Adobe Photoshop CS5. I have just installed the latest version of Luminance HDR, Ver. 2.0.1 and I noticed that it has been greatly improved from Version 1.9.3. It’s easier to use and the improved performance is really noticeable.

Supported HDR formats:

  • OpenEXR (extension: exr);
  • Radiance RGBE (extension: hdr);
  • Tiff formats: 16bit, 32bit (float) and LogLuv (extension: tiff);
  • Raw image formats (extension: various);
  • PFS native format (extension: pfs).

Supported LDR formats

  • JPEG;
  • PNG;
  • PPM;
  • PBM;
  • TIFF (8 bit).

Supported features

  • Create an HDR file from a set of images (formats: JPEG, TIFF 8bit and 16bit, RAW) of the same scene taken at different exposure setting;
  • Save load HDR images;
  • Rotate, resize and crop HDR images;
  • Tonemap HDR images;
  • Copy exif data between sets of images;
  • Supports internationalization.

Luminance HDR is available for Linux, Windows and Mac OS X, see Downloadabove. A wiki space provided by Sourceforge acts a central place for all the documentation. A great deal of discussions and images related to Luminance HDR can be found on flickr.

Testing Luminance HDR 2.0.1 - Output 1

First Impression

After doing a couple of HDR images I find it to be a great tool, probably better than picturenaut (another free hdr software) . It now supports Canon CR2 raw files, I didn’t have to convert raw files to Tiff, unlike in the old version 1.9.3. On my testing I was going to use 7 raw files to merge into hdr, but for some unknown reason Luminance crash twice when initially merging those 7 raw files, so I tried to use only 3 raw files and it worked like a charm. Another problem I noticed is when using the Align Images feature. The first set of photos that i was going to use was shot handheld, naturally I would want to align the images, but every time I use the feature, Luminance will crash. If I don’t use the align feature the merge images are a little blurry because they are misaligned. Thank goodness I used a tripod when I took the photos above.

Last thing I noticed is the inability to save the final result to Tiff, I prefer to save the final result to a Tiff format than Jpeg, tiff  retains the full quality of the image, allowing me flexibility to enhance or tweak the image to photoshop if needed.

Well, I still have to do some testing before I can do a recommendation. But for now, based on the two sample photos above, I may find a way to incorporate it in my workflow.
