While musing about the topic and playing with the technique some more recently, I discovered a nice method for some of my landscapes. The source images were automatically exposed raws which I converted to 16 bit TIFF. When combined, the total dynamic range was beyond a single LDR image, so I either had blown highlights or too-dark shadows - even though the information was there in the 16 bits of the output, it had to be squashed into diplayability. So I let hugin calculate the whole panorama twice, once -1 EV from the calculated optimum, and once +1. Then I enfused the resulting two panoramic images. Since the two panoramas are from the same pto, the alignment is perfect, and enfuse picks the nice sky from the darker one and the defined shadows from the lighter one - just the type of dynamic range compression enfuse is so good at.
Alternatively, you could have made a single 16 bit output panorama, and generated the two (-1 +1) exposures from it for enfusing. In effect an HDR workflow with tonemapping at the end. Enfuse's USP is that one can go straight from the multiple exposures of a stack to a tonemapped output, without an HDR version ever existing. What we appear to be discussing is a way of leveraging enfuse's undoubted strength in situations where we do, in fact, have an HDR.
