Did you mean after printing the TIF? Powerpoint is optimized for the screen
and I suspect that when it is saved as TIF it is duplicating the screen
resolution of the Powerpoint rather than the original file you imported.

That is to be expected since they are alternative formats which reproduce
exactly whatever the exporting program gives them.
>I had planned to use Photoshop to crop it and save as a JPEG for the website.
>How can I improve the quality?
Not being familiar with how Powerpoint exports I can't comment on that. I
do know that screen dumps into Powerpoint can be a problem if the PP
presentation is prepared at one resolution (the working PC) and displayed
at another (PC projector).
>Is there a better way to make a montage?
I can understand that Powerpoint can be fast but I would have done the
montage where the flexibility of say Photoshop would easily beat
Powerpoint. Plus you eliminate the processing steps involved in going into
Powerpoint. The old rule about every copying step leading to some
degradation obviously applies.
