The data is all there.

Just need to play with the sliders. Please keep in mind that the screen stretch function is performing a linear stretch on the screen buffer data. This is the reason why you're highlights look saturated and your shadows black clipped. Obviously you need to adjust the red and green triangles to reduce the clipping. The point however is that the data is all there. linear stretching does not show the mid-tones well hence the contrasty look.

Now, take a couple more sub frames and combined them and save it as a 16bit tiff. Use photoshop or gimp to do a non-linear stretch. Or you can use MaximDL's DDP and log stretch functions to fill out the bit space.
