Re: [Digital BW] Artifacts with Digital images

4 exposures, the sensor shifted half a pixel (well) can increase the 
resolution without increasing the noise. The MF digital backs have that 
feature and can go beyond 4x. Their size is already above full frame 35 
mm, well size relatively big. The Horseman bodies allow the use of MF 
digital backs + Nikon 35 mm lenses.

The same is more or less done in the Epson flatbeds and Nikon film 
scanners, several RGB sensors with wider wells placed after another at 
distances from one another interfering with the well distances that give 
a higher sampling rate than one sensor with the same wells wouldn't allow.

So there's another solution to break the fixed sensor size - resolution 
- well size dilemma. Takes time and motion.

I expected an addition to the Anti Shake sensor in Konica Minolta 
cameras that would exploit that idea as well.

The information obtained from high resolution/smaller sensors is getting 
better too. The dynamic range of the Fuji E550 / E10, the better quality 
of the 7MP compacts compared to the earlier 8MP compacts suggest that 
this will improve the information of larger sensors as well.
