Hi
At some point I need to actually test my film speed for more accuracy but at the moment I am not quite setup for it. But I have found that rating pretty much any film I shoot by half (e.g. tri-x @200) and develop for the normal published development time for that particular developer, has immensely improved my negative quality so much so that doing a custom speed test has been put on the back burner. In a high contrast scene I will typically pull for 10-15% development time. So with this logic, if i want to shoot say tri-x at box speed should I use the development times for 800 iso? And would the same apply if I wanted to shoot delta 3200 @ 3200 (vice my 1600) by using 6400 development times?
Thanks to all in advance.
