    Re: Condenser Head Advantage?

    Wonderful pensive pose, seems to exude her character. Does she have a slightly wandering left eye? I might crop to a portrait format. Very nice, thanks.

    If you want maximum sharpness in the bridge then treat the bridge itself as a pretty flat Schiempflug plane running from right foreground to left end of bridge. Thus you could use backplane tilt by...

    Yes Louis, I missed the 8 X 10 requirement. I think the Nikon set barely covers 5 X 7.

    Re: Bellows too short for infinity focus

    Yes, possibly do an exchange for a Nikon 360/500 T ED convertible tele. Very high quality optics with really good contrast, a feature that is very important with tele lenses.
