Yes, that is why I said "ripple" and "virtually". Taking the peaks as a normalized '1' the valleys are at say 0.9 which is a change of -0.15 EV - not much in terms of exposure.
Either you can go on-line and research all things HSS or I can go and then tell you what I think which you may not then understand. Could take a while to reach agreement by the looks of it ...2. The curtains appear to be heading to infinite speed.
I'm more than likely totally lost. Either that or the graphs are not what I think they are. Same thing I guess.
That puts us at the level of Poisson statistics ... if one photon at 555nm wavelength whacks my green sensor pixel, there is a 35% chance that an electron will be generated and stored as a charge in the photodiode capacitance during exposure.PS Just to throw an extra clog in the gear box: What level of light intensity is required to produce an effect on the sensor?
So maybe enough photons that the ADC output would be raised by one least significant bit with a 95% confidence level.
