thanks 2f/2f. Wow it was a long post! I think i will use the NC, positive films are way too expensive for the develop too... I have 3 metz cl 45 the are preatty old but they still work...but is the only ligth I can afford rigth now . I have builded 2 softboxes using old cartons cause I cant buy me new ones.

Here´s a link on my flickrs page where I have used the DIY softbox both left-rigth 45° degrees to the subject 1,5 meter high.
Do u think they could work for that shoot or I have to borrow real ones?
