    Hi Christopher.

    Well that depends a little! As you have seen from PO the Dalsa sensors behave differently to Kodak regarding long exposures. So we will wait a short while longer to see what can be achieved.

    Well yes I know that from my P65, just wanted to know if perhaps Hassi found a new way to extend the expsoure to let's say 5 or 15 minutes. If I read your replay correct it is more like the P65 which is around 30-60 seconds depending ISO and shooting conditions, am i right ?

    Why do so many people need/want 5 minute exposures?

    Most do not.

    Here is a longer exposure: H3D II 39 ISO 50 15 seconds HC 80 at F5.6...taken at 0400am. Internal clock was off in the EXIF data. 5 minutes would not have captured what was evident at the time.

    I imagine for ethereal water or sky longer exposures may work.

    I was a little concerned about the P65+'s lack of long exposure capabilities, but still bought it over the P45+. Honestly, for interiors (the bulk of my work) at ISO 50, I'm rarely longer than 4 seconds.

    I don't want a 5 minute exposure, but if the back can do that long i am at least getting very good 30 second exposures.

    Nice work Chris. Lots of folks don't really know how much work goes into shots like this.

    Re: Hassy H4D/60 Data Sheet

    Thanks, guys. I think I did manage that one in under three hours ; ) I started by turning off all the ambient lighting in the foreground, setting up maybe 15 hotlights... 3 of those and a silk hidden behind the column in the middle of the shot. I love the challenges of lighting maybe more than any other aspect of my work...
