    White Balance Problems

    Today I took out the G1 for a first walk hoping to do some serious shooting. I m still a newbie using this camera. The results were awful. Has anybody encountered similar problems? Who could help?

    Data: Sunny day, 11 AM, partially snowy, camera set to spot metering, "A" mode, lenses I had used extensively with good results and no problems on the M8, Novoflex adapters. Pictures resized from original JPEGs, no other corrections. RAWs show same W/B problem.

    Attachment 11223
    Landscape 2, better colors, grass much too dark, too much contrast (for my taste) , Nikkor 4/20mm, ISO 100

    Thanks

    Peter, This may sound silly. Did you check the WB settings? Usually AWB (auto white balance) returns a decent color palette for these conditions.

    I know where you think it was set to daylight on camera but can you look at the exif data and see what is says on the original RAWs for the white balance setting.

    Unfortunately WB seems to be the G1's achilles heel. I've pretty much settled on correcting in RAW if shooting colour with mine, using a preset to get close initially. But blue casts are one thing I've run across in similar situations.

    I cannot find any white balance information. How can one get at it?

    If I look at the In Camera Temperature in Raw Therapee it is set to 2741 for the first picture

    In Silkypix, you can change the WB to anything you like, Peter.

    Sure Vivek, as in any other RAW converter I know, but that is an inconvenience I would prefer to avoid. Editing 50+ pictures to even be able to preview them properly after a days shootout is not my idea of pleasurable photography. No such problem ever with the M8.

    Hi There Peter
    There is your problem - daylight should be somewhere between 4800 and 5300 (roughly, depends on converter etc.)

    I agree that you should be using the sunlight symbol for outside, but I wonder if it got changed inadvertantly, or some camera setting over-rode it. (or, indeed, RAW therapee has done something).

    Just this guy you know

    Peter, I don't know if Silkypix has this option since I haven't tried it yet, but quite a number of other RAW converters allow you to correct one image and then copy/paste that info (WB in your case) to all the others---and that part would be done (I happen to use LR 2.2).

    That might be a possibility, Jono, since it would be easy to accidentally touch the small WB button, for instance when setting the zoom for manual focus. I think this should be improved.

    Hi Peter Werner
    Nice to see you here on this forum as well
    I'm not familiar with the G1.
    But when I look at the Exif informations with Opanda IExif Viewer I see the following data (among others).

    First image
    Exposure Program: Aperture priority
    Light Source: Unknown
    White Balance: Manual white balance (!?)

    Third image
    Exposure Program: Normal program
    Light Source: Fine Weather
    White Balance: Manual white balance (!?)

    Could it be that you have chosen some sort of manual WB that overrules all other WB related settings ?

    Hi Steen,
    Thank you for your analysis
    The WB button of the G1 is very small and you can easily touch it accidentally when setting the G1 for manual focus. I guess that is what must have happened. In future versions, they should modify this and/or making it more difficult in Firmware, such as asking for confirmation when modifying WB.

    Peter,
    I went to the zoo yesterday and was walking around. At least 4 times my hand set the white balance to K. I noticed it right away each time, and only had a couple of shots that I had to correct. Panasonic really needs to work on those ergonomics.

    Be careful of chimping at the zoo.
