I got a 4x5 off of eBay yesterday. So how should I process the film? B&H has a Yankee day tank. Google Yankee tanks the hits cam back with some negative review about it. Thought about using trays in the dark, but would that leave undeveloped areas on film where it touches the rib of the tray? Even thought about design an extension for the plastic type reels that way I could use my 3 reel tank.
