The full easyHDR PRO documentation is available in form of a PDF document. You can get it from the "download" section of this website.
In addition to the PDF documentation you may also find the following articles interesting:

Take a set of photos of the same High Dynamic Range scene at different exposure times, ISO values or f-stops. In order to achieve best results the Exposure Value difference between the photos should be 1 to 2EV. EasyHDR PRO will load JPEG, RAW (i.e. CR2, NEF, etc.), TIFF and FIT file formats.
Tip: you can start with sample photos that were installed along with easyHDR PRO. There are also tone mapping settings files that were used to achieve the results. You can find those examples in: C:\Documents and Settings\[USER_NAME]\easyHDR PRO 2\examples. On Windows Vista and Windows 7 the "C:\Documents and Settings" folder is replaced by "C:\Users".

Click File->Open and select all of the photos from the sequence that you want to merge into HDR. There is always a possibility to open additional photos or to remove those already loaded. EasyHDR PRO will also load photos that you drag & drop over the program window.
Instead of processing a HDR image sequence you can load a single image and do "LDR enhancement".

In order to get best quality of the result you may try applying chromatic aberration correction. The manual chromatic aberration correction tool works on the input images, so it can be used before the HDR generation takes place. Thanks to this feature you can minimize the chromatic aberration effects caused by imperfections of the lens.

If the loaded photos are misaligned in respect to each other you may choose one of two possible options in order to align them before generating the HDR radiance map. The automatic alignment feature is capable of compensating for shift as well as rotational misalignment. However, by choosing the manual alignment you have much more control over the entire process. The manual alignment tool is capable of compensating for shift, scale, rotation and perspective. Just select the main (base) photo and place the pin pairs (each pair is marked with a different color), so they point exactly the same details visible on the base picture as well as on the photo to be aligned to it.

 |
In many cases however, automatic alignment will be sufficient. Just choose the base image to which the function shall align the rest of the photos and click "Apply". By default the middle exposed photo is selected to be the base one.
When the alignment is done you may save the transformed photos for future use. You can do it any time - before or after generating the HDR radiance map.

 |
After pre-processing the input images (chromatic aberration correction and alignment) you can generate the HDR image. Instead of generating a true HDR radiance map, there is a possibility to merge the photo sequence using a pseudo-HDR algorithm (called Smart Merge) or to generate an image stack (average).
|
| |
 |
After the HDR image is generated, the photo is automatically resized for faster previewing. It is also automatically tone mapped with the currently defined settings.
|
| |
 |
Now you can play with the tone mapping settings in order to find the best result or a special effect that you want to achieve. You can use the already defined presets - in this example "dramatic-dark" preset was chosen.
Tip: hover the mouse cursor over the sliders to see short description of the particular setting.
|
| |
 |
Having chosen the best settings you can finally process the whole image at full resolution by clicking the "Process all" button.
|
| |
 |
Before saving the result you may wish to process the photo using available filters - blur, sharpening, noise removal, white balance, sample/target balance or color tone manipulation. Before applying a filter to entire image you can preview just a selected area.
There is also a possibility to rotate, flip and to crop the photo. Tip: the area selected for cropping can be moved over the image with Shift button held pressed.
|
| |
 |
Now you can save the result (File->Save). When saving as JPEG or TIFF you can choose the input photo from which the EXIF headers shall be transferred (if the EXIF is available). For best quality choose to save as 48-bit TIFF (16-bit per channel).
