There are two versions of easyHDR that can be downloaded from here - easyHDR PRO (if not registered a watermark
appears on output images) and easyHDR BASIC (freeware, but with limited features, not developped any more).
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 of easyHDR PRO 1.xx. Do I have to buy another one for any
new release? You can update to the latest version of easyHDR PRO 1.xx for free, however if you want to use
version 2.xx you'll have to purchase a new license.
