Where in the world did you get those numbers? The latitude of XP2 Super is ISO 50 to ISO 800 with optimum around ISO 200.ywenz said:I wanted to test out the "claimed" range of the XP2 by Ilford, 200-1600 range. Shot the roll at 800 with an f4.5 lens.. eww, I don't want to be caught in that situation again!
No. C41 is a standard process. They put your film in the machine and it comes out the other end. C41 films have a lot of exposure latitude and will give acceptable results over about 5 stops. So, using xP2, you can take shots at ISOs ranging from 50 to 800 and all will be printable. However the best results will fall in the 200 to 400 range.pedro.m.reis said:In this particular case of XP2, if i use it at 200 i must tell the lab that to them adjust the processing??
Yes, you can mix ISO/ASA 50 to 800 all on the same roll. The C41 process doesn't change.pedro.m.reis said:So assuming this, in one roll, the same roll, i can make photos with ASA 50-800 ?
Yes. The frames exposed at 50 would be somewhat overexposed, but not so badly that they'd be unprintable (highlights would definitely be blown out). And those exposed at 800 would lack shadow detail, but they'd be printable.pedro.m.reis said:Where would be the "correction" ? in the printing?
It would depend on the subject. I would not recommend using 50 for a snow or beach scene. However, for flat lighting (fog or a dull day in the rain) rating the film at 50-100 would probably work well.pedro.m.reis said:If i make 2 photos, at the same object, one after the other, one rated at 50 and the other at 400, what would be the diference on the neg, and on the picture?
You generally pay a heavier price (grain, blown out highlights, completely blocked shadows) with "normal" black and white.pedro.m.reis said:So, where do B&W "normal" films differ?
In most cases with normal black and while you can compensate in printing for exposure mistakes. But compensation is usually best done in developing. Overexposure will almost completely eliminate highlight detail and underexposure will lead to larger grain and no shadow detail.pedro.m.reis said:I can always compensate 1 or 2 stops in printing no?
Slide film has a latitude of about 1/2 stop either side of ideal ... and many would argue a 1/3 to 1/4 stop.pedro.m.reis said:And Slide (positive)?
