New Info: Tri-X shot iso 200--10.5min @20c, then using time/temp chart shows less than 5 min development time @21c. This is not recommended as any film developed less than 5 minutes could result in uneven development. (source:MDC)
i've read that others rated their tri-x at 200 for better results
do you pull the film during developing, or develop it as if you rated it 400
ie. are you intentionally overexposing 1 stop because you find that yields better results with tri-x
