Hi Folks

Having troubles with a few recently developed films.

Have started to notice some a couple of black streaks appearing right down the centre of my negs....not on every frame.....and films taken from different 35mm cameras.

Looking at the negs...it's a feint black line spot on through the middle.

I always let the film get up to temperature before putting in the cameras, put into the dev tanks in a dark room AND inside a changing bag and developing is as per instructions (Kodak D76 with 2 slow inversions every 30 seconds)

I am going to try a different reel (i use Kaiser easy load with the bulky plastic thing on them which helps the film load quicker and easier) and use the standard paterson one without the extra bit, though if it were that scratching (in fact anything scratching) the neg it'd simply remove the emulsion and leave white streaks on the negs....right?

any ideas?

Fortunately not lost anything important...but need to sort this one out.

thanks

Neal
