Hi

No XP2 needs C41 processing unless you want to eliminate its good points.

mini lab or c41 kit at home or mix with scales though the developer is getting difficult to source.

XP2 allows you to shoot at 100 ISO during day and at 800 ISO in evening and use same mini lab without altering process- it will wet print ok at 800 ISO but you may not like the shadows at 8x10.

It's dye image is different from silver.

Some people use 1600!

Id never try to push or underexpose normal film it makes printing very difficult and horrible prints.
