Had a nice chat with guys at photolab.

Maybe it was the red dress, or the fact I mentioned I own Hasselblad, most likely all of it combined but the man from the lab took me to back to the big scanning/printing machine to choose pictures and crops. Both kept talking about old cameras and how sensitive to temperature they were and what was it like to shoot weddings on film in winter and so.

Finally they told me that Hass film backs are pretty crappy and overleaping frames are common issue.
