Not even a good dealer could help much. When I discovered the corner issues of the IQ260 for exposures longer than 15 minutes, Phase One denied to admit any design flaw.where is your dealer in all this?
surely they should have the answer or point you to raising a support ticket with phase?
Sorry I forgot that you have to take the 1 exposure first. It's been a while since I used this.I'm slowly getting smarter. Tested it first with Yunli's instructions. Works fine. A 1-min exposure shows me my happy stuck pixels in all their RGB glory.
Taking a 20 min exposure now.

Thanks for sharing!Mine looks fine in RawDigger. Purple on import to C1, but a WB click takes that completely away.
As shot WB: 3122, -1.4
Custom WB: 3158, -55.8
Looks like something else is going on. Either a light leak in the camera or something with that back.

"Day light" white balance gives a good suggestion about how it's gonna look like in shadows for real-world images.If I WB in C1 and then push it 4 stops, it still is amazingly flat gray.
Well that would definitely have a pink cast since the WB tint is at -55. But since the raw histograms in RD are very uniform between the RGGB channels, then I think that would be a problem with either C1 or the profile. Not with the back."Day light" white balance gives a good suggestion about how it's gonna look like in shadows for real-world images.
Good dealers are often aware of limitations, workarounds, third party options, etc before the manufacturer is and a main driver for the manufacturer to address/improve/provide those things . We've been really interested in this area and doing a lot of research and testing of our own based on the super-high-res time-lapse market.Not even a good dealer could help much.

That's also what I have thought. However even with RawDigger for the real pictures I still have some minor red cast in the shadow for the real-world images. Could you give it a go and see what happens? I think you have some not-so-strong ND filters and you could perhaps use these indoors for long exposure?Well that would definitely have a pink cast since the WB tint is at -55.

Hi Doug, thanks for the explanation. It's interesting to hear that the back will reuse the darkframe made in the first capture executed. I will definitely give it a test!Good dealers are often aware of limitations, workarounds, third party options, etc before the manufacturer is and a main driver for the manufacturer to address/improve/provide those things .

Quick note... what you are doing is not technically "disabling" the dark frame. You are forcing the back to reuse the dark frame made in the first capture executed after enabling the aerial mode.
I would suggest you and your friend's situation is better addressed through your dealer and Phase One than through the forum.
I will try if I have time. Might not be tonight though.That's also what I have thought.

You obviously didn't read #6 of this thread. This problem has nothing to do with darkframe NR. It's a general issue.So it looks like a dark frame mismatch. The back is applying the dark it has taken with the first frame - maybe with 1/60s exposure to the long exposure frame.
So next test:
Take a long exposure image, with NR on. After that, disable the NR, and take another long exposure image. That one should be much better.
So, in a nutshell, whoever designed this thing screwed up; users now have to 'lobby' P1 in order to get them to fix it ?Good dealers are often aware of limitations, workarounds, third party options, etc before the manufacturer is and a main driver for the manufacturer to address/improve/provide those things ...
Like all those diesel owning VW drivers would have gotten the deal currently on the table (in the US at least) simply via their dealership and VW HQ in Germany. Yeah, right.I would suggest you and your friend's situation is better addressed through your dealer and Phase One than through the forum.
Way too premature to state this is a general issue affecting all IQ3 100MP MFDBs.It's a general issue.
