EOS 1D Mk2 custom white balance problem
Hi,
I use an Expo Disc to set custom white balance on a 1D Mk2 in my white high-key studio. Once a custom white balance is set I would assume all shots taken on that setting are using the same colour temperature. This morning I've been testing different raw converters and I've found some 'interesting' problems. Capture One and RawShooter seem to have different white balances when choosing 'as shot' for different images i.e. several shots using the same custom white balance have different colour temps. The shots are also very 'cold'. Bibble does a better job of producing more real colours when using 'as shot'. Canon's Digital Photo Professional seems to have consistent colour temps for all shots and importantly the colours look correct on my calibrated screen. This leads me to think Capture One, RawShooter and to a lesser extent Bibble are not using the custom white balance information correctly. I've seen lots of comments about Canon's DPP software being less capable than these 3rd party converters. But my tests today do worry me. Has anyone else tested this or seen similar problems. For outdoor shots using auto colour balance then Capture One does a great job. But I'm now having doubts about it's colour accuracy. I have noticed previously that the colour temperature for the same image as reported by these raw converters is different for each tool. This can't be right??!! Thanks, Graham. ------------------------------ Graham Russell Photography - www.grahamrussell.info ProSportPhotos - www.prosportphotos.com |

Has anyone else tested this or seen similar problems. I use the 1D M II and both Capture One and RawShooter ... this is a known bug with the latest version of C1 (V 3.6) and with RSE 1.1. Basically Canon "hides" the custom white balance tag and these programs didn't locate it properly, so you cannot use the custom white balance feature with them, unfortunately. For outdoor shots using auto colour balance then Capture One does a great job. I agree, which is why I use it. Supposedly the V3.7 release in May will fix this. In the meantime you might want to browse the C1 user forums at www.rawworkflow.com for a lot more info on this issue, which is a real pain for many users. Bill |

Bill, thanks for the info. At least I'm not doing something wrong!!
I'll just stick with Canon's DPP for now then. I'm very happy with the images it produces. A nice addition would be the ability to see clipped blacks and white when you adjust the end points of the histogram and the dynamica range adjustment. Perhaps I've missed something with the tool, but I haven't found it so far. Graham. "Bill Hilton" wrote in message oups.com...
