<div>Okay so I am liking the HDR scene but I am a little confused here. This questions is regarding Tone Mapping in Photomatix.</div><div> </div><div> There two different Tone Mapping features, Details Enhancer and Tone Compressor. Are they each a separate mapping tool to be used separately or do you use them both for each HDR image you do? In other words do you use one or the other or both on each HDR image.</div>
It's an either/or situation. "Details Enhancer" is a local operator, and "Tone Compressor" is a global operator. You can't really do both at once.

<div>Thank You Jack, so that is what I was doing wrong. I have read all of the Tutorials here at Pop but if you wanted to expand on the two (Details and Compressor) I would appreciate it. Thanks in advance.</div>
From my review/tutorial on DPHDR:<br><br>"And while some other HDR programs have just a couple of Tonemappers, DPHDR has six, including two local, three global, and a feature called "Smooth Compressor," which, as DPHDR describes it, acts as both a local and global operator. (Local and global operators use different algorithms and crunch the data. Generally speaking, Local Operators produce much more dramatic results than Global Operator. If you see a surreal HDR, odds are it's a Local Operator; if it is a subtle photorealistic HDR, it's a good chance it's a Global Tonemapper.)"

<div>Thank You Jack, I appreciate the help. I have read all of your tutorials so far and found they answered most of my questions. I just was not real sure about the Tone Mapping options. Thanks again.</div>
