ChangeLog

20160201
Fix auto-updater of camera database. Apparently, this was not working for quite some time. Thank you to Annie for alerting me.
20131229
Regularly auto-clean tmp upload directory
New file count and disk usage stats on admin page to help with admin work
20120930
Added Hoefflinger to list of references
20120929
Implemented ghost removal
20120920
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 HDRI mailing list. This makes some of the WebHDR functionality available on your (LINUX?) desktop.
Tidied up the 'Other HDR Software' page
Added McCann and Rizzi's book to 'References'.
20110416
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).
20110406
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.
20110227
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.
20110205
Moved to a new server, and tarted up the CSS.
20101023
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.
20100901
Fixed a bug that caused a server Ooops through a corrupted path to the EXIF file.
20100121
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!
20080221
Some housekeeping on Other HDR Software.
20071003
Update the RYO Demo to reflect changes in the new interface.
20070829
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.
20070329
Put all references on a separate page.
Removed commercial software from the Software page.
20070308
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.
20070307
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 bar.
20070216
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.
20070111
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.
20070108
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.
20061107
Change naming convention of output images;
Fix bug that caused a lock-up when the input images were less than 800 px wide.
20061024
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 large.
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.
20060926
Increased the max upload size for the compat test from 3 to 5 MB.
20060909
Added FDRTools to software list
20060907
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.
20060829
Corrected a few typos here and there. Removed Desktop RADIANCE from the software list. Moved PFStools up in the list of software.
20060717
Fix bug that caused the uploader to reject some valid rsp files
20060506
A full-size HDR image is now available for download. So is an OpenEXR version.
More status updates on the intermediate download page
20060505
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 different places.
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.
20060310
Updated info on PFSTools, which only run under LINUX and MacOS
20060309
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
20060306
Added Photoshop CS2 to software list, and two cameras to compatibility list
20060130
Added two cameras to compatibility list
Added Photomatix to list of HDR software
Allowed asterix to be in string of camera model
20060115
Added picture of puzzle pieces, juggling balls and an old door to the Gallery.
20060110
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.
20060109
Linked the Max Planck Institut für Informatik to the Home page
Prettified and updated the Software page.
20060108
Added a Remove Lens Flare tick box to the upload. This defaults to Off, just like in hdrgen;
Added a Galery page with images taken yesterday in Lisbon.
20060106
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.
20060105
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.
20060102
Improvements in Camera Test and File Upload CGI scripts,
New management tool for camera DB (internal use only).
20051229
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.
20051228
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
20051223
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.
20051220
Added new button on uploads page to disable auto-alignment of images;
Added download of tone-mapped image mimicking the humans vision.
20051219
Added the new High Dynamic Range Imaging book to the references.
20051202
Put up this changelog;
Added an About page.
20051121
Added functionality to save the RSP file and re-use it for later sequences;
Added camera calibration.
20051116
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.
20050506
Fixed exposure formula which was missing a square with the aperture. Thanks to Alfio Castorina for spotting this.
20040104
Created falsecolor.cgi to allow for re-submitting HDR images to change the options for falsecolor.
20040103
Split up the monolithic webhdr.cgi into smaller sub-routines.
200312??
Introduced a spool directory, so only one job a time is processed.
20031125
Initial release and posting on radiance-online.org
