I decided to develop the 4x5 film I had shot during a memorial flight here. But I did not want to use 2 press kits to develop 10 sheets of film. So I added some water to the developer and blix to have enough to fill my developing tank. But because I had diluted the chemicals I took a SWAG for my developing times. I added about one minuet and the came out very good. I had 10 exposed negatives when I was done. All with good sharp detail. My first time getting every shot fired off and in-focus with the Speed Graphic.
