    Question about the Sony HLV 42 Flash???

    How come this function does not work with the A100?

    Auto WB Adjustment
    The Auto WB adjusts the white balance automatically, with color temperature information signaled to the Alpha camera before WB is adjusted.

    Thanks

    Sony does some stupid things with their flashes. Kinda like how off camera flash ratios don't work with the 58 when mounted to any other bodies other that the higher end ones.

    Does the manual say it will work with the a100?

    It says it won't work with the A100. I just wanted to know what it did?

    I believe each flash is tuned for daylight WB nomatter what lighting you shoot in.
    So when your body is set to AWB, it is warmer indoors and so on depending on the ambient lighting.
    So with the 42 AWB, it's supposed to maintain the AWB of the camera and not make your shot look like daylight WB when you use in conjunction with AWB mode on your body!

    Then if you shoot in RAW it won't matter?

    I'm probably not the best person to explain this but AWB is basically fully Auto.
    RAW or JPEG, it totally depends on the ambient lighting. If you shoot indoors under incandescent light, AWB will make the image look nice and warm just as if you selected a custom WB in your camera that suits the ambient lighting.

    It's just that AWB is not always accurate and may look too cool or too warm when it is not supposed to. For example when i was shooting my son continuously in AWB without changing locations, about 10-20% of the shots were a different WB because the camera was just guessing. So AWB will not always be accurate.

    However if you shoot RAW, you can change your WB in PP without destroying the rest of you image unlike trying to change it in JPEG.
    In RAW you can just select AWB and fix it later. In JPEG you want to try to have the correct WB because JPEG is a destructive format and messing with it later will impact the whole image.

    So normally if you have a flash mounted and pointed at a subject indoors where the lighting temperature is 5600k and shoot, the output will be lets say 3000k or whatever the flash is tuned for. You will lose the ambiance of the location cause the flash frigged it.

    But with the Sony flash AWB setting, when the camera is set to AWB, it can recognize that the indoor light temperature is around 5600k by communicating with the body and the flash tries to maintain the output at around the same temperature regardless of JPEG or RAW without the washed out cool temperatures direct flash produces.

    I'm not sure if it does this my adjusting the flash power output or by the body temporarily switching to a different WB to offset the temperature of the flash bulb.

    Thanks for the detailed explanation. I think I understand it. I will have to keep shooting and see what I get.
