Other changes
  • MacOS: Fixed possible crash when tone mapping presets panel was resized,
  • Fixed crash when new project was created while 3dLUT dialog was previously shown & live tone mapping was enabled,
  • Fixed some problems with DPI scalability (dialog logo sizes or text/value area length), especially visible at larger scaling ratios like 300%,
  • Fixed issue with nested EXIF headers (EXIF was not found in some kinds of photos),
  • Fixed bug in lens detection in case of some models,
  • Fixed problem when loading very wide photos (wider than 46339 pixels),

It is useful especially in case of scenes with cloudy sky or fine detailed textures. It is very sensitive, so making the effect too strong can bring out noise or JPEG compression artifacts, especially on flat surfaces like blue, cloudless sky.
  • Full EXIF data transfer from JPEG, TIFF and RAW formats to JPEG and TIFF (installation of an additional program: EXIFTOOL is needed).
  • Color tone adjustment in post-processing. Possibility to tweak color saturation selectively for highlights and shadows as well as possibility to adjust color temperature.

  • Corrected problems with the main progress bar.
  • Repaired a compatibility problem that prevented from running the program on Win95/98.
1.42 - 11.02.2008:

New features
  • FITS (Flexible Image Transport System) image format support. The format is used i.e. in astrophotography.
  • Automatic JPEG rotation (on load) upon camera tilt sensor data stored in EXIF.
  • HDR image generation size reduction. Allows faster generation of a HDR image if full resolution is not needed. Can be also used for faster previewing.
  • Drag and drop functionality. Photos that are dropped on the program window are automatically loaded.
  • Possibility (set in the Program Options) to register the program as default for opening Radiance RGBE (*.hdr) image files.
  • Saving the last settings of the HDR Generation window.
  • Improved workflow - auto alignment as a separate tool, saving aligned photos at any time, possibility to undo alignment.
  • Twice faster automatic alignment with rotation compensation.
  • About 20% faster tone mapping.
  • Possibility to choose photos to be involved in the Image Stacking.
  • Possibility to select photos to be aligned manually or automatically.
  • Improved curves tool. Adding knee points with left mouse button click. Removing with right mouse button.

Corrected bugs
  • The "Add directory" option now correctly adds directories that have an "archive" attribute.
  • Repaired copying to clipboard.
1.41 - 04.12.2007:

New features
  • Image stacking - calculation of simple average of input photos instead of generating HDR. This feature shall be used with noisy photo sequences taken at the same exposure settings, however could give good results also with bracketed shots.
  • Additional option in the Manual Alignment tool - possibility to compensate for shift and rotation only, without scaling.
  • Possibility to move the pins in the Manual Alignment tool with keyboard arrows. Click with the mouse on the pin and while still holding the mouse button use the arrows.
  • The program warns if the user tries to save the result photo when the size reduction is enabled.
  • Possibility to turn off some of the confirmation dialogs, i.e. when a new project is started.
  • The memory usage is smaller, so bigger photos can be processed. With the /3GB switch enabled it is possible to process photos even bigger than 50MPix.
  • The program windows don't pop up during the batch processing any more. So, during the batch processing, other applications can be used without interruption.
Corrected bugs
  • The program will finally work on systems with /3GB switch enabled.
  • Default values in the tone mapping settings are now written with the proper decimal separator - as defined in the Regional Settings in Windows.
  • Corrected bugs in the RAW loader and converter - long paths or filenames (not in 8.3 format) shouldn't be a problem any more.
  • DCRAW should work on Windows Vista.
  • Temporary TIFFs created by DCRAW are now properly deleted during the batch processing.
  • TIFFs saved with AutoPano software will now load without problems.
  • The "Maximal image dimension" setting in the "Program Options->Automatic size reduction" is now working.
1.40 - 09.10.2007:

New features
  • Saving the HDR image in Radiance RGBE (.hdr) file format.

Corrected bugs
  • Possibility to run many instances of the program (i.e. two easyHDR's running in batch processing mode to more efficiently use the multi core processor capabilities).
  • Loading RAW files from root directory (i.e. "C:\").
  • The program crashes no more when HDR is regenerated and the size reduction is other than 1x.
  • Corrected sample tool in the white balance and sample/target balance.
  • Possibility to process *.hdr photos in the batch processing mode.
1.32 - 24.06.2007:

Auto alignment (for now translational only). Much improved toolbar and extended abilities of settings sliders. Preview size reduction - it is possible to process a resampled version of the HDR during tone mapping settings tuning instead of the entire photo. Possibility to hide the right panel, go back to the default settings, revert settings...

1.24 - 21.12.2006: Bigger open and save picture windows. Bigger and more handy sliders. Real saturation parameter instead of the "old saturation" tool that is since now called "compression". New language version: easyHDR in French.
1.23 - 06.12.2006: Additional language versions (German & Spanish). Added JPEG EXIF headers transfer capability. Corrected auto-preview feature. Some other minor changes like progress window showing up when photos are loaded.
1.22 - 11.11.2006: Much faster (3-8x) tone mapping with the Gaussian and bilateral shadows/highlights mask. New tone mapping method - combination of results created with the Gaussian and bilateral masks. Automatic preview option. The preview area is updated automatically when one of the tone mapping parameters is changed. Also, a bug preventing RAW conversion has been repaired. The bug concerned cases when there were spaces in the RAW file path name.
1.21 - 19.10.2006: JPEG error #36 issue has been resolved. Two bugs that were causing crash in Sample/Target Balance have been repaired. Result saving settings (like JPEG quality or TIFF compression) are now saved and restored as program starts.
1.20 - 28.09.2006: The 'Step 3' tab has been redesigned and two new tools have been added to it. The new tools allow color tone adjustment to the tone mapped image. More on that can be found in the documentation. Also DCRAW integration with easyHDR has been improved and the DCRAW converter has been updated to the most recent version (which finally works fine also on Windows 2003 Server). Some additional minor changes like: new cursors, '1:1' and 'fit to screen' zoom buttons.

1.18 - 06.07.2006: Batch processing, project save/load, tone mapping settings save/load.
1.17 - 13.06.2006: No crash during processing if "Auto Add" is checked before the first image is opened. Status of "Auto Add" and "Shadows/Highlights Mask" checkboxes is saved on exit and restored when the program starts.
1.16 - 05.06.2006: Two bugs corrected - crash when bilateral tone mapping was applied at low edge value and a crash on loading some TIFF images i.e. saved in PTGui).
1.15 - 14.05.2006: TIFF format support added. You can load 24, 48 or 96-bit (HDR floating-point) uncompressed or compressed with "deflate" method TIFF images. The tonemapped result can be saved as 24 or 48-bit TIFF (with or without compression).
1.14 - 04.05.2006: If you have purchased or you are going to purchase easyHDR please be sure that you have downloaded at least v1.14. A small bug that could occur on some computers has been repaired. This error affected only a licensed version.
1.12 - 30.04.2006: The most time consuming procedures as tone mapping and filtering are executed in a thread that works in the background so the application window does not freeze during processing. The median filter functionality has been improved (opacity and threshold parameters added).
1.11 - 12.04.2006: Bug correction. Now the program can be used at other screen dpi resolutions (eg. 120 dpi), not only at 96 dpi.
1.10 - 07.04.2006: New tone tmapping algorithm (shadows/highlights mask) - allows much greater contrast reduction between bright and dark areas, but preserves local contrasts, so the images look really neat. Corrected filters (gauss, bilateral and unsharp mask) - now they are faster and have greater functionality (opacity, amount values). Auto add feature (can be used if there is no shift between images to be stacked).
1.04 - 25.02.2006: New stacking and tone mapping method that does not loose color information and allows higher contrast. Corrected gamma adjustment and some minor bugs. (LAST FREE VERSION).
1.03 - 08.02.2006: No image size limit, image alignment with a mouse, contrast enhancement - setting points on the histogram.
1.02 - 04.02.2006: Two errors in image shift procedures corrected.
1.01 - 03.02.2006: New compilation (for 6MPix images).
