easyHDR 3.17.0 – High Dynamic Range imaging

EasyHDR is a photo editor software for Windows and Mac. It uses HDR image processing techniques (High Dynamic Range imaging, or HDRi) to make your photos free of unwanted over and under exposures. This program really takes your works to the new level, allowing you to achieve stunning, realistic or dramatic results.

Finally you can get rid of underexposed, overexposed and noisy areas in your photographs. You can also discover new possibilities – by taking pictures in places where are very difficult lighting conditions.

It is capable of importing many image formats: JPEG, 8/16-bit JPEG2000, HEIF/HEIC, 8/16-bit TIFF, PNG, FITS or any RAW photo.Thanks to integration with DCRAW and LibRAW. EasyHDR supports RAWs from Canon (including CR3 format), Nikon, Sony, Fujifilm, Panasonic, Pentax, Olympus, Leica, Kodak, Samsung, GoPro, DJI, etc. Also RAWs taken with smartphones.

Assitionally easyHDR can import OpenEXR (*.exr), Radiance RGBE (*.hdr). Also the 32-bit floating point TIFF HDR images that were previously generated with any other HDR photo processing software.

With easyHDR you can apply lens correction to fix chromatic aberration and lens distortion, then align the photo sequence (manually or using the automatic feature) by compensating for shift, scale, rotation and perspective misalignments. Objects that have moved while the HDR sequence was taken, can be removed with automatic or manual ghost removal tool.

EasyHDR Features

• Merge several differently exposed photographs (JPEG, JPEG2000, HEIC, TIFF, FITS or RAW) into a HDR image.
• Tone map to get the final result. With tone mapping algorithms of easyHDR get realistic or dramatic HDR results – you got the flexibility.
• Develop RAWs from all kinds of cameras and make HDR photos.
• Lens distortion and chromatic aberration correction.
• Enhance a single RAW or JPEG photograph.
• Free Adobe Lightroom plug-in (installed along with easyHDR).
• EasyHDR is a multiplatform HDR photo editor software – works on Windows and macOS.
• High DPI display support (compatible with 4K or Retina screens).
• Correct the white balance during tone mapping, or in case of RAWs, also at import step.
• Live preview while working with full resolution of the photo.
• Work with layers and masks – define different tone mapping parameters for various areas of the photo. That gives unlimited flexibility. A must have for an advanced photographer.
• Apply 3d LUT color grading – easyHDR imports any LUT files.
• Automatic, but also a unique manual Image Alignment allows to process photos taken without a tripod. It compensates not only for shift and rotation, but also for perspective.
• Automatic and manual Ghost Removal feature ensures that moving objects (cars, people, clouds or trees) won’t spoil the final photo.
• 360 degree panorama awareness option (applies tone mapping properly on the left and the right edges of the image).
• You can boost quality with noise removal filters. It can be done before and/or after the photo is tone mapped.
• Advanced Batch Processing allows fast processing of big numbers of input photographs. The HDR sequences are found automatically.
• Built-in and user thumbnail presets.
• History of tone mapping parameter changes – allows live undo/redo.
• Clone & healing brush tool allows removing dust particles, or unwanted objects from your photos.
• Fully supports Color management.

Changes in easyHDR 3.17.0 (2025-11-26):

New features

• MacOS: native support for Apple Silicon (Apple M, Arm CPUs). EasyHDR is now an universal binary working natively on both newer Apple-M as well as older Intel Macs. No more need for Rosetta 2. That also boosts easyHDR performance by 10-30% on Apple M computers. Minimum supported is now macOS 11.5 Big Sur.
• Manual alignment; option to draw additional feature rejection mask, used for auto pin placement,
• Added option to select OpenEXR pixel format (see in Program Options). Previously only 16 bit float was supported, now user can also choose 32 bit.

Improvements

• Improved noise filtering for Local Contrast,
• Auto alignment; reject features close to image corners and edges, it should improve alignment in some cases,
• Manual alignment; the auto pin placement option respects method selection (shift-only, shift-rotate, or shift-rotate-perspective),
• New command line parameters, to allow HDR image output and skip tone mapping,
• Improved mouse cursors in Ghost Removal tool.

Other changes

• Fixed crash when handling failed HEIF load,
• Fixed possible crash when switching Layers,
• Fixed issues with GUI scaling for various screen settings,
• Updated Qt framework to 5.15.17,
• Updated OpenEXR library for 32 bit format support,
• Updated LensFun database with new camera and lens definitions for lens correction,
• Updated LibRAW for new camera RAW support,
• Updated Exiftool,
• Updated OpenJPEG (support for jp2 and j2k formats).

Changes in easyHDR 3.16.2 (2024-06-27):

New features

• Added AVIF image loading support (*.avif images, with AV1 compression). Supported natively on macOS 13 (Ventura) and later. In case of Windows, the required system version is Windows 10 1903 or newer, but required is also “AV1 Video Extensions” codec utility by “Microsoft Corporation” (free, via Microsoft Store), if not already installed in the system.

Improvements

• Distortion correction in the crop tool is now split into two separate, X and Y values, allowing better adjustment of photographs taken with fish-eye lenses,
• Fixed and improved flat frame calibration of RAWs. It was not working properly in case of some cameras due to bad black level (bias) value that was being assumed,
• Added EXIF transfer option “Keep MakerNotes”. Enabled by default (as it always used to be). Uncheck to fix issues with segmented EXIF being not recognized by some other software,
• Use “Flash Exposure Compensation” value when calculating EV,
• Improved preview for the sharpening effect being applied at tone mapping stage,

Other changes

• Corrected linear mode of chromatic aberration correction,
• Fixed issues with handling huge photos (arithmetic limits),
• Fixed stability issue in batch processing,
• Updated LensFun database with new camera and lens definitions for lens correction,
• Updated LibRAW for new camera RAW support,
• Updated Exiftool.
