Hi,
I installed Jonaugust_69 _v55.67 camdriver with support for HDR photography (Manual AEB Shutter for HDR photography).
There is the following in the readme, but I don't know how to make 3 different photos in a row?
Picture Quality Normal:
New Scenes:
2.1 Manual AEB Shutter for HDR photography
EV-0.7 => EV-2.0
EV-0.3 => EV+2.0 { 3 Shuts
EV 0.0 => EV 0.0
EV+0.3 => EV+2.0
EV+0.7 => EV+1.0 { 5 Shuts
EV+1.0 => EV-1.0
EV+1.3 => EV-2.0
Is there any better camdriver for HDR?
Thanks

I guess if you have GIMP or Photoshop,
You can adjust exposure from single image..
For example, I use GIMP.
I have an image namely "DSC1234.jpg"
Open it with GIMP.
On the toolbar, select "Colour" > "Curves"
Then you'll see a y=x graph,
Just pull/drag the middle point of the line one y=x+1 box up.
Save the image as "DSC1234overexposed.jpg"
Now you have +2.00 EV from the original file.
Open the original image on GIMP again,
Same method, but this time, you pull the middle point of the line one y=x-1 box down.
Save as "DSC1234underexposed.jpg"
Now you got 3 different exposure from 1 image,
No need to use tripod or anything
Done!
Well, if you notice all my HDR images on HDR topic, I use this method on all of them.

of course this single picture technique have nothing to do with real HDR in which various exposures are still most important. single picture technique is just tone mapping

easiest way will be 3 shots with 3 different exposure compansation (EV) values. your cameraphone cannot do 3 shots at once and no matter of what you have to press the shutter key more than once
