Thank you, that was a really good article. Been doing a ton more research.
Think i'm slowly getting there.
The ISO info is very helpful too.
I conducted a little experiment on ISO/noise using my digital camera (Canon 550d)
I shot two images of similar material, but my ME super showed up with a lot more noise.
Is this normal for film cameras using 400ISO? I don't mind there being noise, as long as it's normal and appropriate to the film stock, and it's not mine or a camera error that's causing it.
Both images were shot at 1/60 with a 50mm lens The canon was at 1.8 and the ME Super was at 1.7.

Something i'm finding really strange is that i also shot a series of images at night, also at 1/60 1.7 with the ME Super and there was no detectable noise at all in the correctly exposed shots.
Even the underexposed images (shot at around 125) weren't noisy. The blacks were grey, but the grey was quite smooth.

Again, could this be a difference in the labs i'm using?
I asked the man in the new shop if they had tried to correct anything and he said that it was developed straight with no corrections.
This film stock was also Superia XTRA, as opposed to Premium. Could that be a factor? The difference is quite huge, so i'm a bit confused!
Will try more experiments tonight. Thank you again all for your input.
