I reported a couple of months ago about a Black Frame Syndrome<\/a>\naffecting my D200, whereby the raw image data was fine, but the embedded\njpg previews were all black. (A NEF<\/span> file has two embedded JPGs<\/a>.)<\/p>\n\n

Because I shoot<\/span> raw<\/a>,\nthe only practical effect for me is that I get<\/span> a black<\/span> frame when I try<\/span> to\nreview the images on the camera LCD, but someone shooting in JPG mode would\nfind all their images completely blank. Yikes!<\/p>\n\n

This happened to me for the second time yesterday, but this time I\nbelieve<\/span> I've figured it out.<\/p>\n\n

It turns out that the D200's white balance setting can be set to a\nwhite<\/span>-balance preset that has not yet been defined, and when this happens,\nyou get the Black Frame Syndrome. The raw file<\/span> is saved with the\nwhite-balance notation as if automatic white balance had been selected, but\nthe non-existent preset is used for the JPG engine, yielding a blank<\/span>\nframe.<\/p>\n\n

Thus, if you find yourself suffering from “Black Frame Syndrome”, check\nthat your white-balance setting is not “Pre” (or, not one of the five “Pre”\nsettings that's not yet defined).<\/p>\n\n

The white-balance setting is adjusted with the thumb-wheel while holding\ndown the “WB” button, and it turns out that I sometimes<\/span> hit that by\naccident when I intend<\/span> to hit the ISO button next to it. It's my fault<\/span> for\nusing the wrong control, of course, but it's certainly a camera<\/span> firmware\nbug that it allows you to use a white<\/span>-balance preset that hasn't been\nset.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
