There is no discrepancy indeed.
After exposing and processing the film you still need to print it (or telecine), which is what John is refering to. There, just like in the previous steps, you can make adjustmens as well. If you overexpose your neg and process it normally, you will have an overexposed negative. Then when you print it, you can correct for this overexposure by printing down (making it darker), so that your endresult will be correctly exposed image.
By rating the filmstock differently from the manufacturers rating (either overexposing or underexposing it) and correcting for this in the printing, one can achieve different looks. A lot of Dops tend to overexpose their stocks by a third to a full stop, especially if they are shooting Super35, to get tighter grain and good blacks.
On the other hand there is Harris Savides who underexposes his stocks sometimes between 2 and 3 stops (as he did for 'The Yards), to get a more mellow look. For that film he shot anamorphic, which due to its greater negative area allows for more underexposure latitude than say Super 35.
ok i see. when choosing to pull process there are two decisions to be made:
1) development time of negative at processing stage and
2) stop adjustment at printing stage (i assume this is where it will become a positive print)
i think i'll be using this process for a 16mm film i'll be shooting so there'll be more questions coming soon, but here's another i can think of for now:-)
is there necessarily a difference between rating the stock at a different asa and using the "new" stop reading as opposed to leaving the rating the same and just making your own stop adjustments??? hope that makes sense.
also on a side note. where did you start making your own films and camera assisting - UK or Luxembourg? its just i'm from the UK myself and was curious about the way in which you've combined an obvious commitement to making your own films as well as working in camera depts on other projects. this is a route I am particularly keen to follow. any info very much appreciated.

p.s. thank you for all the other info.
