bit pedantic to go on about a specific definition, if it does the same thing then what does it matter what you call it?
indeed- i'm just asking if his objection was to my definition of fill or technique.
petersmart said:Not quite - a single photon or electron has very little energy - for example it takes about 624 Eev to power a 100 watt bulb for 1 second (The E here stands for Exa which is 1,000,000,000,000,000,000) - so even if the photodiodes were 100% efficient - which they're not - amplification would still be necessary to reach the energy levels required for the memory cards.
i imagine there are a number of intermediate steps between sensor and memory card - ultimately there could be a process where the low energy signal is interpreted and converted into whatever the memory card needs to process.
