Hi losheng,

I usually develop black and white negative, so I don't have the standards for E6 handy. But sure, control strips are useful and they would come with documentation of the proper readings. If you were going to "do-it-yourself" I don't know. Maybe shoot some test target shots, like Zone System users often do, and send one roll to a lab - process one roll yourself and check the differences...
