Still have a Colour Cast

[palker]

Hi guys,

Not sure if this should be posted in M8 or Digital Darkroom.

I've an M8, with the Leica IR/UV filters. It has 1.110 and coded lenses with the lens detection on. I'm using Aperture 1.5.6 and Mac OSX 10.5. I only take RAW images.

Over Christmas I've taking photos and under Tungsten light (manual white balance set in camera) with a Summilux 50mm and I still get a Magenta tinge.

Ok its not a pain to remove the biggest amount of it .. I use the Mid-Range colour tint wheel from the exposure tab and push it away from the Magenta side towards the Green and a little de-saturation - usually about 0.9. I've saved this as a Preset.

It is mostly visible in people's faces, and lips. Where everyone looks to be wearing pink face powder and lipstick.

The filters were an improvement (thanks for the free filters from Leica).

What am I doing wrong? Is there anyone else with this combination getting similar results?

I have had the camera about 4 months now, and I'm finally getting the hang of the other techniques, like focussing 🙄 but this is a pain that I had hoped would be cured with the filters and coding.

Phil.

The manual white balance has to be set with an expodisk or grey card. Try auto white balance, or tungsten if you are in that environment.

Update,

It's been that long since I used Photoshope ... I forgot to try my images there. I opened them in Adobe Bridge/Photoshop and no colour problems .. so it looks to be an Aperture thing.

Any Aperture users got any help to offer? Apart from wait till Macworld 🙂

Bottley is right, under Tungsten use Tungsten to get a decent default setting. It is no problem to correct just about anything if you are shooting DNG though. I find I have to tweak white balance on about each shot - with any camera. Do make sure you use a calibrated monitor, otherwise your prints may turn out surprising.

Hi Jaap,
Its not about white balance, without any adjustment in Aperture the reds blow out towards pink, lips and faces look a little like there has been pink face powder, I also noticed our red leather sofa goes towards pink too. Same Photo no adjustment in Photoshop/Bridge (CS2) opens with normal face tones and lips that look like no lipstick.

Trawling last night I found some similar posts on LUF, and it seems that the RAW.PLIST has changed under 10.5 For the M8 it seems to have an A and B profile and that Aperture somehow decides which one to use.

** Update **
So I finally fixed it by doing the old trick of using the Nikon D200 profile. I found the raw.plist and after a making a copy of the file I pointed the M8 profile at the D200 settings. And no more blown pinks .. and normal skin tones are back.

I hope any changes we are hoping for this week will not set me back .. if so I Spotlight will work and find the raw.plist this time.

I now have a small exercise to re-generate all my M8 previews to stop the profile doing it each time I open the images .. no big deal, and then undo my Color Tint wheel changes.

Bon Chance.
