Well I was very low on high grit film...so got two sheets (A4) .
Including postage it was £11 exactly...I think that is quite expensive over time compared to a lifetime with a good stone, as I already said, you can sell a stone on....film goes in the bin, I got 0.5 mic so it is really just a polishing grit, if I had to buy all the grits needed for a film progression I reckon it would cost plenty, also, when the film turns black, I bin it, I can feel how smooth it has gone and you can check the non grit side for a comparison, I dont think film wears like stone, ie: it loses grit at unequal rates, where a stone is more "uniform". How do you all decide when a piece of film has became u/s ?.
