>>3639011Yeah the lubricant drying up is what I thought too. I figured the cold was making it worse as I don't have that issue indoors or when it's not super cold.
Those specific lines look like surge to me rather than bromide drag though. You can get either. Bromide drag is from under agitation and surge is from over agitation. On 35mm it comes through the sprocket holes, but on 120 it just looks fucky.
