2) Technical example. Since you have asked about High def
I queued up one of your B&W neg and have captured a couple of frames to illustrate something.
graintest0000.jpg is a 5.2 meg capture of a frame (this is a colour capture). Examination of the frame may lead you to believe there is sensor noise as can be seen in the grey noise.
Bring up graintest0000.jpg and graintest0001.jpg separately with a jpeg viewer set to a viewing scale of 1:1.
Flip back and forth between the two images and you can see the noise structure barely changes at all. The grain noise stays put.
In fact graintest0001.jpg is an average of 64 captured frames. If the graininess seen in graintest0000.jpg was due to sensor noise, or light source noise then basics physics would dictate that graintest0001.jpg should have 8 time less noise which is not the case.
Now in fact, I can see a tiny noise reduction in graintest0001.jpg which is also suggested by the lower jpeg file size.
It may be tempting to attribute this small change to image sensor noise averaging , but alas I suspect this small change is due to micro-vibrations in the room during the 64 frame sampling. I suggest this because the image of the dust particles become marginally less sharp in the 64 frame averaged image graintest0001.jpg whereas they should become sharper if there was no physical vibration.
Consider 8mm /2500 pixels = 3.2 micro meters per pixel and you start to get an idea of how little vibration it take in the transport system, camera etc. before the extra resolution is wiped out. Even after you transport a frame there is usually an elasticity to the film which will give after the transport.
Getting the lens and sensor up to high definition specs is just the start of it.
I am not sure what the grain size specification is for your film - it would be nice to know.
Of course in the case of colour developed film each of these grains may appear as colour noise.
One thing I have noticed and need to think about is that I can even see colour fringing around the suspenders. Is it due to
a) original camera?
b) light diffracting through film base?
c) my lens ?
d) software?
The odd thing is the fringing is present even around the3 centre of the image which is not normally the case with chromatic shifting with lenes.
