There are two versions of easyHDR that can be downloaded from here - easyHDR PRO (full product,
trial - if not registered a watermark appears on output images) and easyHDR BASIC (freeware, simple
features only, no further development).
easyHDR PRO
An unregistered copy of easyHDR PRO is a trial version of the full product. It is fully functional,
however a watermark is added to the output images. If you want easyHDR PRO to
produce results without the watermark please register your copy
by purchasing a single-user license - you will receive the s/n and the key that will
remove the watermark.
Language versions:
easyHDR BASIC (freeware)
EasyHDR BASIC is much less featured than easyHDR PRO. There are implemented only the
simplest and most basic HDR genearation and tone mapping functions. However this version
is free.
How do I update to the new version? Just install the new version over the previous one. Uninstallation
of the previous version is not needed.
I have purchased a license for one of the previous versions. Do I have to buy another one for any
new release? No, once purchased license is valid for all releases of easyHDR PRO 1.xx.
