From: Mr. Bill [mailto:[EMAIL PROTECTED] "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? From: Harman Bajwa [mailto:[EMAIL PROTECTED] "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.
