TIFF file from PSD

Question

Does saving a PSD file to a TIFF file format destroy or otherwise do anything to the pixels and/or quality of the file? I'm asking because I user Silverfast to scan in to PS CS5 Extended and when I saved each scan I did so as a PSD thinking it is the best option. But now the issue is that I can't edit the PSD file with Camera Raw which seems to have much better global options to fix image issues.

Answer 1

function(){return A.apply(null,[this].concat($A(arguments)))}

ACR purportedly has the correct "workflow" (not quite, but certainly better than PS). Another advantage of ACR is that it won't modify the original, so that is kind of good too.
LOL, define "correct 'workflow'".  It's impossible.  Anyone claiming to have a "correct" workflow is deluding themselves and possibly others.  It's even quite possible to challenge the term "better".
There are people teaching that doing image editing actually IN Photoshop is somehow "bad".  Keep in mind they make money by teaching, not by getting results with Photoshop.
And your statement that ACR "won't modify the original" is literally true because ACR isn't an editor in itself and does not have a "Save As" capability.  However, if you open a TIFF file with it into Photoshop, then do File-Save you WILL overwrite the original.
My point is this:  There's a lot of "accepted dogma" in the Photoshop realm that sounds really right.  Just be wary of it, and try to understand what it really means in your own context, because it simply isn't always right.  There is no "right".  There's too much art involved to even define "right"
Most things you can do in Camera Raw you can do in Photoshop proper.  I agree that Camera Raw does give you different ways to do things, which may well be more understandable.
