- 1/12s: take first snapshot (JPG image with 1/12s exposure. Shutter remains open)
- 1/6s: take second snapshot (JPG). Shutter remains open.
- 1/3s: last snapshot of the sequence. Save the third image and finish process.

What do you think?

I'm dreaming of a better way to take HDR Photos Single Pass in this case in 1/3s:

Take a 1/3s Picture at once and reading the Picture from the CCD in three runs!

Open the Shutter, read after 1/12s, still exposuring, after 1/12s the 1/6s picture and still ongoing after 1/6s the 1/3s picture. Then you can close the shutter.

Mmmh... a dream!

It is not possible for the CCD I guess?
