The S45 does not rotate images in the camera. All it does is set a
tag in the EXIF data to indicate the orientation the camera was in
when the picture was taken.
With the EXIF data orientation set, software can:
- Display the photo correctly (but not change the actual file)
- Perform a rotation (usually losses) on the actual file, and
re-write the file.
Note that the JPEG files contain both the actual image data and a
thumbnail. You would normally want the orientation of both to be
the same (I think!)
First... Some camera downloading software have the option of
automaticaly rotating the image based the embedded EXIF orientation
information. I use Downloader Pro by Breezebrowser, which does this
(and I use this option).
This does a lossless rotation of the actual file. Downloader Pro is
smart enough to re-write the Orientatation data back to "none", and
rotate the thumbnail so that downstream software does not get
confused!
Next.... Some image viewing/browsing software has the option to
display the image based on the EXIF orientation information.
(BreezeBrowser has this option). In this case the actual file is
not re-written, just the display is changed.
Finally, Some viewing/browsing software software allows you to
batch rotate the files based on the EXIF orienttation tag.
Stupid Newbie Move: After getting used to taking lots of photos in
a portriat orientation, I proceeded to try taking movies on my
S45... you guessed it... in a portrait orientation! Hmm... if I
turn my laptop sideways..... Oh Well..

BTW, do you know if rotating the original in the camera is lossless?
Thanks,

You probably know that ZoomBrowser rotates the images when they are
transferred if it senses that rotation is enabled in the image.
This function is set in the S45 menu.
If you are not using ZB for transfer, you can still rotate images
after the transfer. Open ZB to the folder with the images, select
and rotate them via the rotation button on top. If the images have
been edited, ZB will sometimes produce a warning of quality loss.
Another option, in the tools, preferences menu, you can select to
rotate the original or (create and) rotate a copy.
