If so, is there a different way to get the same results?
If you're using ACR shoot RAW, I just got - but haven't used Photomatrix (time issues) which I guess allows you to use JPEGs (don't quote me on that + you should always shoot RAW anyways).
Setup on a tripod and use the self-timer set to 2 seconds or as long as you want to wait if you don't have a remote shutter release. Expose the scene correctly (take a test shot & look for your shadows and highlights to reach the 'compromise' you would normally be forced to make).
Wherever you end up with your aperture setting for your artistic taste, keep it there. Now shoot the scene with varying exposure lengths. Keep it open for one frame 2 stops +, one frame 1 stop +, then reverse the other way with you're shutter speed settings.
Now you have 5 RAW images that go from too dark to too light with the 'correct' exposure in the middle. In PS go to File>Automate>Merge to HDR, pick your RAW images and see what you get!
I'm sure someone can explain Photomatrix & tone-mapping better, but as far as getting the needed shots, I hope the above helps.
