Thinking about all these approaches for getting increased dynamic range.
What software can combine images in the following fashion?
You sample a scene over multiple exposures.
You sample one exposure to pick up shadow details and another to pick up detail in the highlights. Nothing new there!
You notice certain pixels change value in relation to their surrounding pixels!
For example, an area in the scene shot at 1/1000 sec was all black. You then shoot the same scene at 1/100 and noticed the pixel in the centre is darker than its neighbors.
Or similarly, another part of the image was all white when shot at 1/100sec.
You then shoot the same scene at 1/1000sec and notice the pixel in the centre is darker than its neighbors.
Can you get the mean difference (average or similiar) value of any pixels that have changed in relationship to their neighbors, and use this new pixel value in a combined image?
