'Hot pixels!'

Wayne, the Hasselblad backs have the dark frame info built in. It's not an omission, it's a benefit.
How can you build it in? it varies based on exposure time and temperature. You can calibrate out some of it, but then pretty much every camera maker does that as well.

Didn't seem to work for the OP.

I think that is up for debate at the moment. He does say that he doesn't actually know what a hot pixel looks like. I don't see any. Maybe David Grover can step in. All I know is that it works for me, and has done so since the H3D.

Here's a link to 'no dark frame' in action: http://forum.getdpi.com/forum/mediu...cks/[email protected]

Try opening a file directly in ACR, that has known effect with hot pixels with some camera's. I will see if i can find the link for the information on it.

wow, those links are old ... any evidence the issue still exists? They're talking about ACR 5 (7 is due any time now) and the other thread is older than that.

Yes Wayne, people are still saying ACR removes the hot pixels. Apparently it was Thomas knoll who wrote that bit into ACR
