1. I sent the following yesterday, don’t think it ever showed up on here:

Your software (e.g., Photomatix) can take a single image and use those for an HDR process. Much like what Ralf’s manual process is doing, the software as I understand it will take your original file export, create a working file dupe that is underexposed, another that is overexposed, then combines those as those they were were three original exports. You are throwing away a lot of information that might have been in the originals if you had done the bracketed exposure in the first place. 3. If you do try the in-camera HDR option, you will find that the time you are waiting for the camera to process the several exposures into one HDR file and then write that file to the card is a good time to read a short novel. Or you could drive to a nearby Starbucks or Tim Hortons and get a coffee. stan On Mar 31, 2015, at 8:44 AM, Eric Weir <[email protected]> wrote: >> On Mar 31, 2015, at 3:27 AM, Ralf R Radermacher <[email protected]> wrote: >> >> Doing your HDR in postprocessing has a number of advantages.
