Green and magenta skies (???)
« on: June 09, 2012, 02:04:16 pm »

I am seeing strange shifts in images I'm taking when processing them with lightroom, both with thet old and new processes. Attached is a rendering, exported WITHOUT any LR edit (all cursors at 0). I'm using a D3, with the recent 28-300. What's going on?

Thanks in advance for any help.

Best,

Stephane

Was it RAW or jpeg? How does it look in any other processor (other than LR, that is)?

Sorry for the lack of precision of my initial post. The original was RAW of course. The size of attachments on the forum prevents me from uploading the original image.

How about camera settings? What color space, saturation, contrast? Any special "styles" (landscape, portrait, etc.) applied in camera? How about Camera Calibration tab settings in LR? Also, have you tried other converters?

Especially Camera Calibration panel in LR: what profile are you applying?  I recommend one of the "Camera ...v4" profiles.  For the D3, I'm pretty sure Eric Chan's original profiles weren't optimum, and there should be the "...v4" profiles in the choice, which as I recall avoided hue twists in highlights.

Setting in LR4 is just Adobe Standard, no camera profiles applied

Almost looks like a fractional shift of one of the colour channels. CA at the corners does look too bad (not familiar with this lens)

Are you applying a lens profile?  Do you get the same with and without?

Could you post a 200-300x crop from the sky so that we can look at actual pixels?

Are you getting this on other camera bodies / lenses?

Is this new (ie have you had good files from this combo before?

Can I suggest you try the "Camera Standard v4" profile on the image, and see how that compares?  (If there's no v4 shown, just use "Camera Standard".)

Are you sure there's actually a colour shift in the sky?  I've seen storm clouds with that coloration in real life
