Hi Creophoto,
Sorry, but if I'm reading you correctly, you are wasting your time. You take your photos at 0.1 stop per shot?
Depending on the level of contrast you are working with, three shots at -2, 0, +2 are all that's necessary. If you are in a dark room with a bright outside window, than going over to more shots may (probably) be necessary but again, only 2 stops per shot.
If you are taking raw images you could get by with -2, +2 (no "0" shot), but JPG you will need all three.
Think of it this way: think of dynamic range of a shot like trying to get a panorama of a scene. To go from the left to the right, with a 50mm lens, you might need 3 shots (with 1/3 overlap of shots) to capture the entire range. A 50-75% overlap would not create any better of a panorama. But if you had a 24mm lens (think of this as the raw image that captures more data), you will probably need only two shots to get the same amount of panorama that the 50mm required 3 shots.
I did an experiment years ago where I took the following shots of the same scene:
-2, -1.5, -1, -0.5, 0, +0.5, +1.5, +2
I then processed them as such:
-2, -1.5, -1, -0.5, 0, +0.5, +1, +1.5, +2
and
-2, -1, 0, +1, +2
and
-2, 0, +2
For each test I processed them exactly the same way each time.
Finally, I compared the results: absolutely no difference.
Now, I can provide to you two different approaches to do bulk processing of your images:
1) from within Adobe: use Lightroom Classic. Select all your images, do a right click, and select "Auto Stack by time." Now comes the (semi) tedious part: select a stack and press Shift-Control(Command)-h. That will perform a headless HDR (whatever your settings are, it will process them without your interaction). So this will be (1) select stack, (2) press the command, (3) repeat 1 & 2 till done. this will cache in LR until done.
2) Get Photomatix. You can select a folder within Photomatix and give it some guidelines and then go have lunch as Photomatix will process that folder of images.
HTH, let me know.
