Improving TIFF previews.

Dear members:


The TIFF files I have stored in my system are viewed in Bridge's slideshow
with lower resolution than that of my monitor which is an Apple Cinema
Display 23" (1920 x 1200). I am currently using Bridge CS2 although I also
have Bridge CS3 installed in my system.

My idea is that the previews in the TIFF files are of lower resolution than
that of my monitor. In this case, do any of you know if there is an
application for the Macintosh that allows one to resize the embedded
previews in TIFF files so that they are full size previews ? The TIFF images
I am trying to view come from two different sources - a point-and-shoot 3.3
megapixel Olympus Z3030 camera and a Nikon Coolscan 4000 slide scanner used
to scan color slide film.

In case these TIFF images are converted to DNG and the option to include
full size JPEG previews is chosen the images generated display well under
the slideshow with the proper resolution. This would be an alternative but I
am not sure if I wish to convert these images to DNG at this point since
support for DNG is not nearly as universal as that for TIFF (Apple's Preview
which is an application I use frequently does not provide ample support for
DNG).

Another possibility is the fact that Bridge treats the TIFF files in a
different manner than it does RAW. I have used Bridge mostly with RAW images
from numerous different cameras and have never experienced a problem (with
CS2 that is) displaying these images with the slideshow view. Perhaps Bridge
treats the TIFF files differently and produces downsampled images during the
slideshow view despite the fact that the embedded file previews are of good
enough resolution and quality.

Do you have any idea of the reason why I am experiencing this problem with
TIFF files ? Is there an application that will allow me to resize the
embedded preview in TIFF files .

Is there a way (perhaps an application) for me to check the size of the
embedded preview in a TIFF file ?

Thank you for your help.
