Interesting. I know the sensitometer at Kodak Rochester for testing MTF exposes the film with line pairs between 2 cycles/mm to 100 cycles/mm, so modulation past 100 cycles/mm for those EXR plots would be extrapolated. As mentioned prior, stock specifications published by Kodak are "customer...

I've skimmed through this discussion so forgive me if some of these points have already been stated but to offer some potential insight. Kodak Vision compared to the previous Kodak EXR stock primarily saw an improvement in sharpness for the cyan dye layer (red sensitive layer), aside from that...

Depending on the scanner. I had a monochromatic scanner in mind which can adjust the analog gain of each channel exposure made via custom filtration. But in both scenarios, amplifying the sensor voltage or manipulating the raw input code values can only work with the electrons captured. Think...

Exactly. For color negative in particular, most people use high CRI white illumination and neutralise the base via white balance, but that's effectively analog gain, polishing a turd signal. If instead the orange mask were neutralised with light (cooler spectra), it would allow for a more...

Yeah base fog typically sits around a transmittance of 0.5, so that's appropriate. 14-bit would be fine for colour negative especially. It must also be noted that base density is an average, there's a good stop in transmittance above and below contributing to granularity for D-min.

It's always preferable to use at least a 16-bit sensor, especially for black and white film which can reach a D-max of around 3.0. If we assume a 14-bit sensor, there's very little code value resolution for highlights. CV 16383 - 100% transmittance - 0.000 density CV 8192 - 50% transmittance -...

This section seems to line up with what I've read from other studies: "A photographic emulsion layer may be exposed and developed, then all but a single layer of grains next to the base washed off. By studying the remaining grains with a technique called residual grain analysis, described by...

Your assumptions seem quite sound. I had a quick skim through "Modern Photographic Processing Vol.1" which was recommended above. They presented quite high resolution photomicrographs of the reduction process of individual crystals. The reduced silver ions form more of a filament structure, even...

Heaps of great resources shared here. Thank you.

I read somewhere that developers distinguish between exposed and unexposed silver halide crystals by a particular threshold determined by the amount of reduced silver ions in the crystal lattice structure. They particularly observed a threshold of around 3 - 5 reduced silver ions to silver atoms...

Hi, I'm trying to interpret the differences between log sensitivity and "relative" log sensitivity for a given color negative spectral sensitivity curve. First off, how is spectral sensitivity for a given color negative measured and plotted? Why is it the case for Kodak 2242, that it is...

Okay cool, I think i'll give the Zeiss a try then. Looks promising. The main question I was asking is whether or not the Zeiss supports everything the f3 has to offer, such as aperture priority. Or are all manual aperture F mount lenses compatible?

I'm wondering whether the Zeiss Planar T 50mm f1.4 ZF.2 would be a good functional match for the Nikon F3, meaning it completely supports the Nikon F3. I've only came across two images of people using them in combination. So it's either an undesirable match, or that the budget for the...
