Re: Pictorico pinholes
Diana, Low humidity will definitely cause more dust marks on the negative and perhaps more pinholes. I use a humidifier in the winter when making negatives. If you still get some pinholes or dust marks, these are a pain because they will print black with most processes and thus are hard to spot on the print. If I get pinholes or dust marks on the negative, I put the negative on a light table emulsion side down and look for them. Then I spot them with an extra fine Red Sharpie pen. This will block the UV light and give you a white spot on the print that is much easier to touch up. The R1800 seems the worst of the lot when it comes to pinholes and dust spots.... I think this is because the inks are slower drying. Best Wishes, Mark Nelson Precision Digital Negatives - The System PDNPrint Forum at Yahoo Groups www.MarkINelsonPhoto.com
