ToDo

Some things I would like to implement sooner or later, given the time. Please don't be shy in requesting other features that you think might be useful. See About Page for contact details.

• Facilitate storage and retrieval of camera's RSP file and calibration factor;
• Enable vignetting correction.

ChangeLog

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
