Has anyone else encountered this problem with the Nikon D1x? If so, how can this be avoided or fixed? [img]/ubbthreads/images/graemlins/confused.gif[/img]
When using studio lights, the models skin has large blotchy reddish areas, (on legs, stomach, sides of face),where non exists in real life. Also, models hands are often red/magenta compared to rest of body. It is clearly visible on my PC screen and also shows up when printed on my epson 2000p. The same pictures shot with color negative film have normal skin tones, no red blotchiness. I am using a nikon approved IBM microdrive card, shooting in high res Tiff and Raw format. I have sample pics if anyone would like to see examples, but an unable to post them here. Nikon has not yet come up with an answer. Thanks!

Hmmm... I also shoot with a D1X and have never experienced this problem. Would like to know all the settings and tech specs that were involved.
Here is an image from Rolando's first Philly Workshop. Wish I could go again this year but it just isn't in the budget.
Model is Hillary
Cam is D1X
Lens Nikon 28-70f2.8 AF -S
Lighting Dyna-lite
shot at f8 and 1/250 sync speed. ISO set to 125

Thanks for your reply. The reddish areas on skin appear in about 1/3 of my shoots using my white lightning studio lights, camera settings vary but usually f8-f11, 125, nef and tiff high res. The red tones seem to show up where there is slight shadowing rather than just darker skin tones as you would normally expect. It loooks as if the models have a reddish rash on the stomach or legs, or side of face....very annoying since i shoot a lot of glamour and figure study. Almost impossible to fix in photoshop.

Does it happen in any other instances? other lighting conditions? Where you are ..is it damp? hot? What is the white balance set on? Have you tried setting the white balance +/- ?

Wild guess - assuming there's nothing wrong with the camera and that it's simply recording what it "saw" -

I wonder if it could be due to UV in the flash? The WL's tubes are not, as I recall, UV shielded and it's possible the amount emitted varies somewhat with the recharge time, etc.

Can you reproduce the problem? If so, try a UV filter.

Good luck

John

Turn off auto tone compensation

What you describe sounds like the result of "auto" tone compensation in the D1X.

Open Nikon View, and find two images taken near at the same time, one that shows the effect, and the other that does not. Also open the "Shooting Data" panel. Then with the mouse click from one image to the other and back in Nikon View, and watch the shooting data. I'll bet one has a different tone setting than the other.

I set Tone Compensation to "Normal" and leave it there... don't leave it on auto or let the camera set it.

I have been using the D1x for about a year and have never seen this problem under any lighting conditions. But one thing is for sure: the Auto tone setting, Custom setting #24, is not your problem since this has no effect on the raw NEF files. If you have eliminated your lighting setup as the source of the problem then I have only two other guesses: 1) the NEF conversion program you are using or 2) an actual problem with the camera that needs fixed by the factory. Let us know how you solve this this one!

This photo taken with a D1x, RAW, converted by Bibble 2.99. Only minor color correction and dust spot removal in PS.
