EasyHDR PRO 1.50.2

EasyHDR is an image processing software that produces high dynamic range (HDR) images from normal, 24-bit, photos taken with a typical digital camera.

>> blend a sequence of photos taken at different exposure values into a High Dynamic Range (HDR) image
>>tone map HDR image into an 8-bit per channel REALISTIC looking result that can be displayed on computer screen or printed

>>align the input photos using manual-alignment feature (compensates for shift, scale, rotation and PERSPECTIVE) or...

>>...use auto-alignment feature, that compensates for shift as well as rotation

>>adjust tone curve shape to fine-tune the contrast

>> do post processing on the tone mapped result without any quantization losses - on floating point data (blur, sharpening, noise reduction, white balance, color tone adjust)

>>convert and tone map RAW images from your digital camera

EasyHDR blends a sequence of photos taken at different exposure times and applies tone mapping in order to create the result. No more overexposed or underexposed photos. With easyHDR BASIC you will be able to create pictures with dynamic range of human vision or even greater!


What is a HDR image?

High Dynamic Range image covers much wider dynamic range (light to dark ratio) than a normal digital camera can record (due to noise and overexposure). A HDR image is created by blending an image sequence of photos taken at different exposure values (various exposure times or ISO sensitivity). Each photo in the sequence shall cover a part of the dynamic range of the photographed scene. The resulting HDRi will therefore contain the full information from all of the photos.

How to take an image sequence?

If you try to photograph a scene and get some unwanted over- or underexposured areas you may consider taking a bracketed sequence that could be later blended to HDR and processed. The easiest way to do so is to turn on autobracketing (AEB) in your digital camera, set the number of photos in the sequence and the EV (Exposure Value) spacing. The 0EV photo will be taken at the exposure time, ISO and the f-number measured by the camera as the best for the particular scene. The other photos will be deliberately underexposed (negative EV) or overexposed (positive EV) so they will contain details that are lost in the 0EV photo due to noise and overexposure. The photographed scene should be static - there should be no movement or light change during the photo sequence acquisition, otherwise ghosting effect will be visible in the assembled HDRi. Therefore you should use a tripod to take the photo sequence. EasyHDR, however, has a built-in auto-alignment feature that compensates for shift and rotation between photos, so taking a photo free-hand won't necessarily mean a bad result. If the autobracketing isn't sufficient you may want to manually vary the exposure time, with the constant ISO and f-number. When you i.e. take 3 photos at 1/200 (A), 1/100 (B) and 1/25 sec (C), this will mean that the photo (A) is underexposed by 1 EV relatively to the photo (B) and the photo (C) is overexposed relatively to (B) by 2EV - so you have a photo sequence: -1EV, 0EV and +2EV.

load BMP, JPEG, 24/48/96-bit TIFF, FITS and Radiance RGBE file formats

save as BMP, JPEG (without loosing EXIF headers), 24/48-bit TIFF or Radiance RGBE (.hdr)

use batch processing option to automatically process tens of image sets without any user interaction

easyHDR features and requirements:

Operating system: any Windows (95/98/2000/2003 Server/XP/Vista)
Screen resolution: 1024x768 or higher
Memory: more RAM means that bigger images can be processed. Recommended minimum: 512MB.
The program is "Large Address Aware", which means it supports the /3GB setting enabled in Windows.
Image file format support
loads: 24/48/96-bit TIFF (uncompressed or deflate compressed), Radiance RGBE (.hdr), 24-bit JPEG, 24-bit BMP and FITS
saves: 24/48-bit TIFF (with or without compression), 24-bit JPEG (without loosing EXIF data), Radiance RGBE (.hdr) and 24-bit BMP
built-in converter DCRAW can convert RAW images from most digital cameras (among them: .RAW; .CRW; .CR2; .RAF; .MRW; .NEF; .ORF; .DNG; .PEF; .X3F; .DCR; .KDC and .SRF) to extended dynamic range, 48-bit TIFFs (without quality loss).
Manual alignment: uses a planar stretching method to compensate for shift, scale, rotation and perspective misalignment.
Auto alignment: easyHDR is able to automatically compensate for shift and rotational misalignment.
Generates a true HDR image or a simple stack of photos.
HDR generation with an anti-blooming option.
Global and local tone mapping operators.
Curve adjust tool.
Histogram black & white point clipping. Manual or automatic.
Preview: process only a selected area or the whole, resized photo.
Program settings can be saved to a file and later loaded. You can also save and load entire projects.
Batch processing - you can prepare a list of image sequences (with associated settings) or previously saved projects, choose result file format and destination directory, click "Do all" button and leave easyHDR to do the whole job automatically. You can also do LDR enhancement or HDR file generation only (without tone mapping).
Postprocessing, while still working on floating point data (no quantization losses). Available are: gaussian blur, unsharp mask, median and bilateral (noise removal) filters and also two color adjustment tools: neutral point (white balance) and sample/target balance.
Image transformations: rotate, mirror and cropping.
Program is in English, Polish, German, French, Portuguese, Russian, Italian and Spanish language versions.
