This is again wonderful Emil. Would love to try this out once. Actually, since you are using the defunct Polaroid 665 pos/neg, how do you apply solarization??? I have never done solarization, but from what I understood, you have to apply a short burst of strong light during development. Do you peel apart the polaroid before full development, and than close it again or so???
Marco: almost: overexpose a little - then let it develop as normal for about 20 sec (depending on how much solatization you want) - then re-expose (I peel the film/positive apart, and then give the negative a strong flash exposure - then just leave the negative for a couple of minutes, and then do as allways (water - rinse - fix).
