Strictly irrelevant to the video's purpose, Andrew, but what always amazes me is how long you seem to have available to examine a processed neg in good room light before needing to put it into the stop bath. Just out of interest how much longer might you have had, should you have needed it, before the negative was damaged by the light?
The follow-up question is : Would it be possible to examine for a few seconds at least a developed film on a reel and then if it was clearly underdeveloped, put it back into the developer for a further period with no effect other than the desired effect red of increasing the development time
I suspect that there might be some problem with doing this if an attempt is made to place it back into the developer i.e. in effect damage is done only if the extra light during the examination is acted upon by more development but I cannot get my head around why this happens
This question is open to responses from others whose knowledge may also provide what precisely happens that prevents success with examination and then re-immersion
Many thanks
