enblend: input image UINT8 but previousUINT16

[ll0zz]

Hi,
I tried to use Hugin on 7 Tiff16 images from my EOS5D camera.
Process can't complete (see below).
I'm using Hugin 2010.0.0.5045 (in french) with Ubuntu64 10.10
All images have been converted the same way from raw (.CR2) to TIFF16 using Ufraw 0.16

Tiffs generated by Hugin seem to be indeed different, the first (panoQuaix100000.tif) is 38.6Mio whereas others (panoQuaix10000n.tif) are around 23.2Mio

Regards,
GB

Can you install tiffinfo, run it on all the input photos and send the result here?

Unfortunately Hugin (or rather enblend) doesn't support mixing 8bit and 16bit photos. If Hugin has somehow created a mixture of 8bit and 16bit files from uniform 16bit input photos then this would be a bug.

Thank you for the tip about tiffinfo, exactly what I was missing to check if the files were Tiff16 or Tiff8.
And indeed it seems I had trouble with Ufraw that memorize some settings between two images, and doesn't for some others, so I ended with mixed Tiff8 and Tiff16.
So this was not a bug.
But maybe Hugin could warn user he's mixing 8 and 16 bits images, or enblend show a more explicit message ?

Nevertheless, thank you for your time and your work.

What version of enblend do you have? a comment in an earlier report (Bug #679094 (sf-2549583)) for this issue says it is fixed in enblend.
