"They not only contain the actual pixel data, but can contain a lot of other
data in the tax (where the "T" in TIFF comes from)."

Last I heard TIFF stood for Tagged Image File Format. Is "tax" a typo?

"But yes, IMHO RAW would need to be translated to an 'Image format' before
it is usable for printing purposes."

Everyone seems to be confusing what the RAW decoder is doing. It is not
converting from RAW to TIFF or JPG because both of those formats contain
RASTER data, along with a few other things such as ICC profiles. The RAW
conversion is simply applying all the camera settings that are also stored
in the RAW format, not so much a conversion as an alteration much the way
using curves alters the appearance of a photo. Conversion would imply a
change of format and raster to raster is not such a change.

RAW is the same as all the other formats plus it adds info as to how the
camera was setup allowing you to use those values or change them. With JPG
you can't easily change them.

From: Sharcy [mailto:[EMAIL PROTECTED]
"A RAW file always needs to be converted to *something* before anything can
be done with it. You can not save, print, or even view a RAW file without
some sort of conversion/translation. RAW, at least to my understanding
(anyone feel free to correct me if I'm wrong), is not a pixel format in the
same sense as JPG or any of the other formats ..."

No, I'm pretty certain, with my failing memory, you can view a RAW file
without applying the camera settings. I did it once on accident while trying
to view a file shot at something like ISO 1600. Without the camera settings
applied the photo was nearly black.

But, the main issue is the confusion between CONVERTING and APPLYING. The
RAW file is all raster data combined with all the camera settings embedded
in the file. RAW conversion doesn't convert it to another raster format
because there is no inherent difference in TIFF & JPG raster formats. It's
all pixels of black/white, grayscale, or color just saved in a different
fashion ... just as RAW is saved in a different fashion.

Once you open the RAW, with applying the camera settings, or a TIFF/JPG in
PhotoShop to print it is no longer a "format", it's all raster data.
