Could use some help with this one. I tried using the 8X10 BTZS tube to develop some negatives the other day and all of them had scratches in the emulsion. OK, I'm new at this method. I've tray developed my large negs in the past with no problems but thought this might be something I could use with more control in the darkroom. Problem is my darkroom is not all that light tight, so I usually wait till it gets dark, and since the day's are longer now...well, you get my drift. My solution was to use my Harrison Pup Tent to load the 8X10 in the tubes. Kinda like stuffing 10lbs of "stuff" in a 5lb bag. I realize I would have more control not using the tent but thought I'd ask for other folks experience with this system. Thanks.
