How about a few specifics like ... ISO, Exposure time etc.
More likely noise than dust but why do you ask?
Are you planning on a series at max magnification...200% on glossy 11x14s?
Michael Reichmann calls it pixel peeping .... does the photo on the left not appeal?
Get real...and start shooting. These backs are good for a million exposures...start looking for a few good ones.
Just a thought.

Terry,I don't know if your comments are fair. If I just got a brand new expensive back I certainly would be looking closely at the files to make sure all was OK so I could report any fault back to my dealer immediately.
Its 50 ISO, 1/320 and flash.How about a few specifics like ... ISO, Exposure time etc.

I just came back from studio.Willow did you clean the sensor before returning the back to see if it was simply dust ?
Have you checked out the noise reduction tab and tried the single pixel slider?Took my first pictures with my IQ140 today.
When I zoom in, I discovered a lot of grey spots.
Looks like dust??
Anyone knows what it is? Dead pixels?
I now tried the single pixel slider.Have you checked out the noise reduction tab and tried the single pixel slider?
It could be possibly an exposure artifact or High Iso Noise.
Here is a link to the Phase One Help Page on the topic.

You need to click on the thumbnails for a larger view. He is not referring to the 3-4 large gaps in the hair, but rather to several pixel size gray specks. If you click on the image, you should see them.I may regret this and feel like a dope, but what I see is the magnification of the section in the frame where the background light is visible through the hair. It does not look like noise at all but rather, a slightly oof bleed-through of the light that when magnified, looks like a strange artifact.
Apologies if I'm way off or not seeing what you're seeing.
Best,
Tim
Oops, yes I see them now. Thanks.You need to click on the thumbnails for a larger view. He is not referring to the 3-4 large gaps in the hair, but rather to several pixel size gray specks. If you click on the image, you should see them.
I'm inclined to agree with Guy. If the spots I am seeing are the gray spots that are being referred to....they are a somewhat irregular in size, randomly patterned and not dark black, like most dust spots. Many times, dust spots are black and spaced out considerably more than I am seeing here. Your gray spots instead remind me of the sprayed grease spots one often sees and been reported on many recent Nikon pro bodies, such as the Nikon D3 (due to mirror slap). If they are grease spots, its sometimes trickly wet cleaning them without creating smudges. Keep us posted when you have some idas what it might be.Try luminance at 20 color at 35 single pixel at 30.
And yes inspect your sensor. Not unusual to have a dirty sensor coming from the factory . Seen it in every camera I ever bought and that is many. Lots of times it is actually loose grease from new parts that gets sprayed around. So you may have to do a wet sensor clean. This is not mixed lighting either he is using all strobes here. End of the day my bet it's grease.
