Possible LR2.1/CS4 Editing Bug

[Andrew Hayton]

Ok here goes,

With preferences set to edit an image in CS4 as a tiff image select an image and select the edit command. The image opens up in CS4 but with no tiff extension, only the original filename say DSCF1234.DNG.
If you save the file as a PSD first it will save correctly as a PSD and be seen by LR in the current library. If you keep the image open in CS4 and do some more editing and then do just a save then you would think that the PSD would be updated but wrong, it actually saves a new file with a tiff extension and the edit naming convention set in the LR preferences.
This could well be design but seems like a small bug or might just be me going completely bonkers

Andrew, I think I remember reading Eric Chan saying that DNGs are fundamentally TIFF files, so that they are sent in 'TIFF' format, but keep the original name.

I know this doesn't actually answer anything, but my impression was that the behavior you're noting was by design.

I been thrashing my email subscription archive, and several candidate forums, and can't find my original reference though, sorry.

That might explain half of the problem as I now convert to DNG on import so DNG is the file format going to CS4 but the saving as a PSD from CS4 should remember it as PSD although this may be a CS4 problem rather than LR although it must have something to do with how the file is tagged.
