Thank you Regina. Yes the photo is filthy with dust but don`t blame it on the film, it was my fault... When I developed this roll I didn`t take the necessary time (I had to get some sleep and was in a hurry to get this done...) so I opened the window while the film was drying and dust impregnated the negatives, I only noticed it when made the prints. I have in the past "worked on" the emulsion, scratching it on purpose but in this case it was only dust... Maybe in the weekend I`ll wash the negatives again. I have to be more conscious about quality of my presentations.
