Dynamic Photo HDR software is formidable, not only for multiple exposures can be used with a single RAW or JPG image with very good results. It is an easy to understand and has several tone mapping procedures
Works with most RAW camera formats
Recently went to version 4 has all the picture settings, including: white balance, levels, gamma, hue, chromatic aberration, Barrel and Pincushion correction, perspective correction and more.
Provides a few interesting filters like Orton Effect
Provides the possibility Color Correction using Kelvin parameters with preview table.
I recommend highly

I have tried this software but I have realised that when I save the photo in tiff format and then I open it in PS it is saved only in 72dpi?! What am I doing wrong? HDR was made with three photos in 240dpi.

What does the dpi matter? It is a printing measure, not ppi.

Some of us print, ya know....

thank you for the info.

The best way to save is in. Psd (photoshop format). This equates to a file of two layers, one is the original file and the other is the predecessor of Dynamic
