Orange bleed on images

Friends, last evening I took the S 006 or for some first very low light shooting. With 70mm mounted and at ASA 100 I got good results with exposures up to .5 seconds. But anything shot slower than that caused an orange cast. Imagine an orange graduated filter emanating from all corners of the image spreading with diminished density towards the image center. Or like a light bleed on a negative or chrome. I am on vacation now and do not have tech to post an example but will do so by week's end. Any one have a similar experience?

Obliged.

David, usually quite intense orange cast can observed when one sets white balance to Cloudy or Shade. I'm not sure if this phenomenon is shutter speed-specific, but you may check your WB settings. Hope that helps but if it doesn't, please let us know.

David we may be able to be more helpful when you can share an example. Much depends on the actual light and source in the scene of course and white balance settings and what is happening in your imaging program and its settings

Gents, thanks kindly for the responses. I will certainly post an image when I am able to get a sample out of the camera at week's end.

Kparseg, I checked white balance which is set to auto.

I did have better luck this evening. Shot some sunset images and fireworks with no orange vignette. Perhaps just an aberration. Still would like to know what caused it.

Today, I also had issues with the Contax adapter that I use with the 35mm and 120mm. Initially the camera would not read the lens. And when I shot out there were two vertical green lines a few mm into the image, east and west. So I triggered the internal software update check (a trick a fellow at Miami Leica taught me) and all was well.

I do love this camera. Have not shot my M9 since I first laid hand on S. After dancing with Nikon DX and Rollei MF, and dabbling in 4x5, I feel that the S scratches every itch. But the reports of body and lens failures, and my own experience with M9 sensor, make me question Leica design or QC practices.

How do you trigger the internal sw update check (006)?

David, as you know the sun and moon often have the orange color. If you observe the orange cast at quite slow shutter speeds (0.5sec or slower), the sensor is getting a lot of ambient light, which is orange. As you've said, if you keep your shutter speed fast, then colors are more accurate. The same principle is behind using central shutter.

 

Do you observe the same orange cast when you shoot landscapes or anything else? Outdoors or indoors?

You press the toggle and then switch on the camera.

Thanks again for you interest.

The phenomenon occurred in the presence of fairly strong orange artificial light in an otherwise dark environment. It was reproducible consistently with shutter speeds below .5 sec. I have since shot at night with even longer exposures without issue. Kparseg, your theory on the intensity of orange ambient light causing the vignetting has merit. Last night I shot shutter speeds up to 20 sec with no ill effects. But there was no single light source as in the offending images. Indeed, I was intrigued by way sensor drew the scene of greenery with isolated pink roses in a scene so dark the auto focus was befuddled. Soft and muted and painted in a way characteristic of those vintage lenses not so preoccupied with clinical precision. Really looking forward to seeing them on a screen.

Best,

David
