You will get something, but very little of any value. I would not bother.circleofconfusion wrote:You'll have to push it 3 stops which, while excessive, should give you some sort of image. It will be grainy and the greys will be a bit crushed but that's better than nothing.
Fuji's datasheet only gives timings for pushing 1 stop: http://www.fujifilm.co.uk/technical/download/acros1.pdf
Find out what the time is for your usual developer at ISO 100 and 200 and then interpolate. As an example:
lfotec DD-X (1+4) @100 9 min
lfotec DD-X (1+4) @200 14 min
That's a 55% increase in developing time so you could estimate the time to push to 400 as 22 mins and 800 as 33 mins. Which is just mad... the developer will be exhauseted by then not to mention stone cold. But it gives you a starting point.
Look at the data sheet for a 'high speed' developer and see what they suggest.
