Bong As long as you are using the same tools and nothing changes it doesn't make a difference. A number is just a number. It is the results that count. I had a student once, a young high school kid who had to shoot at an EI of 900 and the development time was way out there (I don't remember)had great negatives. He had a problem camera and no money to repair. we just figured out what he needed to do to get proper results. Take a breath, use the same equipment, keep time and temperature constant , and if the prints are great don't get caught up in a number(posted 8499 days ago)
