We are newbies and need to improve the lighting and depth in our panoramas.  From one of our previous posts we learned that Photomatix could be helpful in correcting this, and consequently we would like to know if anyone could please give us some tips and advice for using the product.  We take it that we need to take multiple pictures with different exposure times, however we are not exactly sure what exposure times we should use.  In addition, are there any other adjustments that we should make in between shots?  Also, should we use Photomatix with stitched panoramas, or with the individual photos before they are stitched?  Lastly, on the Photomatix website the end result looks pretty impressive, but how well does it actually work in real life?  Any help and/or information will be greatly appreciated.  Thanks
