1. More user-friendly – improved user interface.
2. Shortcuts simplify the job – the ‘overview’ window has been replaced by workflow shortcuts, with single click access to generating HDR images, tone mapping, exposure blending and batch processing.
3. Large pictures are handled much better.
4. Available as a Photoshop plugin or Lightroom plugin.
5. The ‘alignment’ option works with more precision. Though this slows the process, results are far more accurate.
6. The ‘Settings’ dialog, the Preview and the Loupe are all in their own independent windows, and can be moved around the screen separately.
7. Preview can fill the entire screen - this is good to get a close look at image details. Luope and Preview can also be seen simultaneously.
8. Presets are available - one can save and reload presets. This is a boon, as one can save preset values for all the parameters and apply them on a batch of photos without having to do so for each one separately.
9. The Tone Mapping feature has much improved. Easy sliders adjust Strength, to get the right Histogram, Light Smoothing, to get the correct tonal quality of light, Microcontrast controls to adjust ‘flatness’ and give that pop-out feel, and sliders for adjusting Luminosity and Colour Saturation.
10. One can simply ‘drag and drop’ images onto an open Photomatix window to load files. No need to navigate folder trees!
