Speaking of deals, since they are now owned by the same company, does anyone know if there is a cross-platform upgrade possible when going from a Phase back to a Leaf back, or vice versa?

in comparision this example in Sensor Super Plus mode (i.e. at web size) is quite pointless.Here's a 30 second exposure from the P65+ processed with C1
What are you referring to? My example is NOT in Sensor Plus mode and neither was the one Chris was asking about... And my example above is at ISO *200* !in comparision this example in Sensor Super Plus mode (i.e. at web size) is quite pointless.
Chris' example is at 100% pixel size and yours is downsizedWhat are you referring to? My example is NOT in Sensor Plus mode and neither was the one Chris was asking about...
Oh, you made it sound like mine was sensor plus. I'll post a 100% crop tomorrow after I find the original file.Chris' example is at 100% pixel size and yours is downsized
thanks, jack! and it would be great (once more) if you could post a 100% crop.Here's a 30 second exposure from the P65+ processed with C1 at ISO *200*:
Hey, I tried, but you were having none of that!He almost attached me to the bottom of the tripod. :ROTFL::ROTFL::ROTFL:
Thanks for the samples, Jack. I think even on the ISO 200 shot the noise levels are still ok and do not totally ruin the image from a noise perspective. Can't detect any noise whatsoever on the ISO 50 sample.Okay, here you go. Keep in mind the wind was blowing about 50 MPH that morning (seriously, just ask anybody that was there) and even with my tripod relatively low, I got a lot of wind vibration during that 30 seconds of exposure, so these look pretty ugly from a camera motion PoV --- I only use them as long exposure examples.
wow! This looks incredible, I'm going back to filmThanks for the samples, Jack. I think even on the ISO 200 shot the noise levels are still ok and do not totally ruin the image from a noise perspective. Can't detect any noise whatsoever on the ISO 50 sample.
The one problem however I see with all digital long exposures of light sources is how easy they clip. This is not specific to your samples. And I'm not sure how much of the highlight transitions could be recovered from the RAW, but even the ISO 50 shot seems already severely clipped at 30 seconds. It's just one application where film does so much better.
Here's a 22.5 minute exposure shot on 8x10" Fuji Pro 160S at f/22 with a Rodenstock Apo-Sironar-N 480mm:
The shot was taken on 2010-05-28, one day past full moon.
Here is a crop downsized to 1200 ppi which is a little over 100 MP for the whole image:
It's part of SXF airport about 7 km in the distance. But I wouldn't take this image as a reference for 8x10" resolution. There are so many things that can degrade image detail during long exposure times. I rather post this sample to show how film captures light over time because haven't seen that sort of tonal quality from any digital camera in long exposure photography.

Btw, I'd also be interested in hearing from anyone who is using the Hasselblad backs on the Alpa too. e.g. CFV-39 which also looks like a good choice if I were to switch out the 645DF system which I'm not wedded to.
thanks a lot, jack! looks much better than the example i referred to earlier.This shot was 30 seconds at ISO 50 in the same wind, so has the same level of camera vibration and is equally useless as an image for other than this noise example.
Thanks David. Does this require a complicated firing process on a technical cam?Hi Graham,
Don't forget the CFV is available as a 50MP unit now.
Price is €11990, the CFV39 is €9990.
