Astrotu that is a nice edit. Im not familiar with lightroom at all soI do not know what +35 means,I use Nikon capture where you can adjust the exposure up to +-2 stops. If you are using different images you should not need to adjust the exposure at all that should have been done at the time of shooting. I have heard that Photoshops contrast adjustment is not that great in terms of the way it reinterprets the photo, however Ifind the results look good to my eye. Curves works fine as well, just go a little further with your adjustments, always go over the line and scale back, you need to see what is toomuch rather than just slowly creeping up on a point you feel is right.
If you are new to photography and or photo editing on a computer I would say stay away from HDR programs. You need to understand proprer editing first before you get into a higher level like HDR. Its like buying a pair of skis and heading straight to a double black diamond. Many of the people on this site who are posting HDR images are very skilled at photo maipulation and understand how to take an HDR image and allter it in Photoshop to create a stunning image. I have been working with editing for about two years now and have just recently got into HDR. I think I've gotten pretty good at it but a photo can take up to 45 minutes or an hour to get the way I want it.
