WebHDR Roll-Your-Own is currently down. We are looking into this. Apologies for any inconvenience.
- Fix auto-updater of camera database. Apparently, this was not working for quite some time.
Thank you to Annie for alerting me.
- Regularly auto-clean tmp upload directory
- New file count and disk usage stats on admin page to help with admin work
- Added Hoefflinger to list of references
- Implemented ghost removal
- Upgraded to the latest version of hdrgen (28 Feb 2012)
Removed ToDo list from this page. Realistically, It'll never happen...
Published WebHDRtools on the
mailing list. This makes some of the WebHDR functionality available on your
Tidied up the 'Other HDR Software' page
Added McCann and Rizzi's book to 'References'.
- Fixed some lousy coding with the new heat map feature that caused
all available memory (and more) to be gobbled up when large images were processed.
As a result, the uploaded images are now scaled down to 1600x1600 before
any further processing takes places. Also limited the upload to 12 MB (down from 20 MB).
- It seems that WebHDR is finally working on the new host. I've re-written some of the code,
and tidied up most of what was left. Check out the new HDR heat map.
- WebHDR is now fully integrated with the new JALOXA site, except for the dynamic RYO pages
which still have a different look.
- Fixed a bug that caused the ISO film speed to always be 100. Big thank you to Tom for spotting this.
- Moved to a new server, and tarted up the CSS.
- For some bizzare reason, the code that took care of the exposure calibration factor
got dropped. This must have happened around 2007. No-one ever noticed this, but
it's fixed now. Sorry.
- Fixed a bug that caused a server Ooops through a corrupted path to the EXIF file.
- Can't get access to the externally hosted site, so WebHDR is back in LEARN for now.
This also means that some of the recent changes have been lost, and that all recent additions
to the camera and EXIF database are lost. Working hard to bring WebHDR back to a usable
state. RYO functionality is currently not available.
- Re-added Bracket and Picturenaut to the software list. Thanks, Google cache!
- Some housekeeping on Other HDR Software.
- Update the RYO Demo to reflect changes in the new interface.
- Major re-write: Added upload status bar (HDR only, not camera test);
- Much improved status page using AJAX rather than re-loads, inlucing place in queue;
- Re-designed download page, false-colour re-submit is now AJAX based;
- Fixed potential parsing error with user-supplied RSP files;
- Fixed calibration factor that was always ignored (Thanks to Kasper for spotting this.);
- False colour images use auto-scaling introduced in Radiance HEAD release;
- More input verfication and sanity checks, on server and upload page.
- Put all references on a separate page.
- Removed commercial software from the Software page.
- Made some compatibility fixes for IE on the upload status page;
- falsecolor re-submit form is now hidden by default;
- falsecolor scale defaults to 'auto', using the Radiance HEAD release.
- Removed dynamic range indication. It's non-sense.
- Set up a mirror server with the help of the Dachary familiy. It's much faster than
the old one. Will use this new box for development.
- Re-wrote the file upload stuff to take advantage of the UberUploader AJAX status
- An averaged RSP function is generated for each camera that has been used with WebHDR.
It's linked into the Camera Compatibility page. Eventually this averaged RSP function will
be used to process sequences that hdrgen refuses to complete, but the data needs to be
tidied up a bit before this can be implemented.
- One more result: Dynamic range. This is peak-to-peak, so needs to be taken with a grain
of salt or two. Better would be to use pfstats, which will be implemented soon;
- Moved RSP file higher up on the results page to encourage people to use it.
- Added OpenEXR and JPEG-HDR as medium-sized output if file is wider than 800 px;
- New preview JPEG-HDR on Results page, 256 px wide (like the histogram);
- Removed the normtiff tone-mapping operation, since this now done with JPEG-HDRs.
This should speed things up a little;
- Auto-generated Tar ball for trouble shooting.
- Change naming convention of output images;
- Fix bug that caused a lock-up when the input images were less than 800 px wide.
- Added Artizen and Pixel to software list,
- Upgraded to RADIANCE 3.8. The most noticable new feature is the different
colour mapping for false colour display.
- Added histogram to R-Y-0 Results page. This allows you to find out whether
the dynamic range covered by your exposure-bracketed sequence was sufficiently
- Replaced pfilt with hdrcvt for scaling down the HDR. hdrcvt is now also used
instead of pfsoutexr for converting to OpenEXR format.
- Added JPEG-HDR output format.
- Upgraded hdrgen.
- The list of compatible cameras is now updated whenever an HDR is made or a
new model tested for compatibility. This means the the page loads much faster.
- Added page on tone-mapping.
- Increased the max upload size for the compat test from 3 to 5 MB.
- Added FDRTools to software list
- Added CinePaint to software list;
- Fixed a long-standing bug that would sometimes prevent the correction factor
from being parsed.
- The Calibration Factor on the page on camera calibration was upside down.
Thanks to Laia for pointing this out to me.
- Corrected a few typos here and there. Removed Desktop RADIANCE from the
software list. Moved PFStools up in the list of software.
- Fix bug that caused the uploader to reject some valid rsp files
- A full-size HDR image is now available for download. So is an OpenEXR version.
- More status updates on the intermediate download page
- Added info on the rsp curve to calibration page
- removed all the exposure stuff from the cgi files and stuck it into
exposure.pl. It was getting messy, since those routines are used in three
- Fixed a problem with the Casio EX-P600. The EXIF field for the film speed
is called 'CCDISOSensitivity' rather than 'ISO', like with all other cameras.
- Added JPEG-HDR to list of HDR file formats.
- Updated info on PFSTools, which only run under LINUX and MacOS
- Added the original image sequence to the Demo introduction
- Fixed some broken links in the demo
- Re-wrote the Camera Compatibility page. It now consists of an auto-generated
list of cameras that have been used or tested with WebHDR. This list
also links to the EXIF data from all models.
- Merge the Camera Test into Camera Compatibility. One less page
- Added Photoshop CS2 to software list, and two cameras to compatibility list
- Added two cameras to compatibility list
- Added Photomatix to list of HDR software
- Allowed asterix to be in string of camera model
- Added picture of puzzle pieces, juggling balls and an old door to the Gallery.
- Fixed a bug that prevented hdrgen from accepting the no-autoalign and remove
lens flare options;
- Swapped out one of the gallery images against a nicer one;
- Updated the list of supported browsers for the Luminance Map;
- Updated the demo pages.
- Linked the Max Planck Institut für Informatik to the Home page
- Prettified and updated the Software page.
- Added a Remove Lens Flare tick box to the upload. This defaults to Off, just like
- Added a Galery page with images taken yesterday in Lisbon.
- Added HDRView and MakeHDR to the list of software
- Changed the file extension for all HDR images from .pic to .hdr
- Went through all pages and corrected some typos and ambiguities.
- Removed the -d option from the tonemapping. A contrast ratio of 500 (which I thought
was typical for LCD screens) produced pictures that looked too dark.
- Added demo pages for the Roll-Your-Own. They look like the real ones, but come with
pre-defined dummy values. All contents is pre-generated. For those four demo pages, the
site navigation is disabled, and instead additional buttons are used to go back, forward
within the demo, or to drop back to the real site.
- Added a super-cool Luminance Map tool allowing for the interactive display of
luminance values on top of a falsecolor image. It includes a calibration panel to sync the cursor
position with the underlying array of luminance values. This feature needs some more
cross-browser and cross-platform testing.
- Improvements in Camera Test and File Upload CGI scripts,
- New management tool for camera DB (internal use only).
- Updated the Calibration page (I read in the new HDR book last night...)
- Finished migrating all cgi scripts from cgi-lib.pl to perl::CGI,
- Added more sanity checks and feedback on the upload confirmation.
- Sexed up the navigation bar. I didn't wast any time trying to make it look good in
Internet Explorer. If you use IE and think it looks ugly, go out and download any other
brower. Try Mozilla Firefox, for instance.
- Added a printer friendly style sheet
- Added new admin interface (internal use only)
- Changed falsecolor re-submit cgi script, so it no longer requires the browsers referrer
to be accessible. This caused problems with some proxies and caches.
- Added new button on uploads page to disable auto-alignment of images;
- Added download of tone-mapped image mimicking the humans vision.
- Added the new High Dynamic Range Imaging book to the references.
- Put up this changelog;
- Added an About page.
- Added functionality to save the RSP file and re-use it for later sequences;
- Added camera calibration.
- Rewrote the EXIF stuff to use the Perl module Image::ExifTools,
instead of exiftags. This fixed some of the issues with dodgy EXIF tags.
- The false colour re-submit page now keeps the settings of the previous run.
- Updated the camera compatibiliy list. A lot more cameras should work with
WebHDR now. Perl rocks!
- Removed all software featured on the EXIF header page that is not cross-platform;
- Added Reveal and Image::ExifTool to the list of software.
- Fixed exposure formula which was missing a square with the aperture. Thanks to
Alfio Castorina for spotting this.
- Created falsecolor.cgi to allow for re-submitting HDR images to change
the options for falsecolor.
- Split up the monolithic webhdr.cgi into smaller sub-routines.
- Introduced a spool directory, so only one job a time is processed.
- Initial release and posting on radiance-online.org
