I have developed my own BW negatives for 20 years. I am now delving into the carcinogenic world of BW reversal processing. As with any film development, consistency is key to getting repeatable results. I will use the Ilford Reversal Process as published, with PanF 50. My question is in regards to the Re-Exposure, ie., fogging, process. It seems several folks favor just holding it up to a diffused window light source for a minute per side. This seems a little inconsistent, so I'm just wondering if there is some consumer-grade apparatus for re-exposing the film in a precise and consistent manner. I have not been able to find such an apparatus by searching the internet. So, ideally, somebody here is going to send me a link to a < $150 re-exposure apparatus Alternatively, I have a large softbox with a single baffle that gets little use. I was thinking about adapting it to accept a 100watt bulb, and laying the film diagonal across the panel for 60 seconds per side. My only concern with this is that there is a slight hot-spot in the middle, by about 1/2 stop, which might lead to the middle frames being re-exposed differently from the edges.
