If photometrics is checked then even the effect on the preview window is eliminated, so apparently none of this does anything at all.
What is happening is that the exposure fusion function applies the Hugin white balance and vignetting parameters to photos, but not exposure. This is because all exposure fusion is doing is getting the 'best' bits from each photo and putting them together. If Hugin adjusted the exposure of all the photos in each bracketed stack then fusing wouldn't have anything to work with, since all the photos would look the same. (You could argue that Hugin should ignore vignetting parameters too, since vignetting gets removed anyway by exposure fusion, but nobody has ever complained) So the Eev settings are applied with normal unbracketed panoramas and to bracketed HDR output, but not to exposure fusion output. If the result is too dark you need to adjust afterwards in an image editor, beforehand in your RAW converter, or drop the darkest photo from each bracket. Hope this makes sense, basically Hugin does everything in a photometrically correct space - Except exposure fusion which is just a clever visual trick and not photometrically meaningful at all. -- Bruno -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
