Auto Rotate - Image Software
Ida Noe
Maybe I missed it somewhere?
Seems I always have to ROTATE each image that was shot vertically in order
to see it correctly on the computer screen.
What software has the ability to recognize that a photo has been taken
vertically and needs to be saved as such?
It's a bit time consuming if I had to rotate 100 images one by one.
Is there help for this situation??
Thanks.

>>vertically and needs to be saved as such?
Any software capable of doing this would be truly remarkable. Stop and
think for a moment. How is the software supposed to recognise that the
photo was taken vertically? The camera doesn't contain a spirit level or
any other device for knowing that you tilted it when you shot the picture,
so there are no hidden markers in the image file to say that it was shot
vertically.
The only thing the software has to go on is the image itself. Image
analysis is an enormously complicated science at the best of times. Could
you come up with a set of rules for deciding what pictures were sideways and
which in "landscape" aspect ratio - a rule which would work for portraits,
landscapes, indoor scenes, still life and everything in between?

Please feel free to try out my PhotoMan package at
http://homepages.tesco.net/~Keith.Sheppard/photoman/beta.htm.
With that you can select as many frames as you like (using Ctrl + left
click) from a single Windows folder and then say "go and rotate that lot"
before going off to make a cup of tea. I'm sorry that's the best I can
offer. Deciding which frames to rotate automatically is beyond my feeble
wit.

Many Canon cameras do. My Canon A80 does and automatically rotates vertically
taken pictures which can be viewed in the camera's LCD. Then when you later
downlaod your pics via Canon's ZoomBrowser software it will download and save
the pics already rotated. :)
Even my old 35mm Canon Elan IIe would sense a vertical orientation for the eye
focus mechanism. In that camera it had a little ball bearing, I'm assuming as
you could hear it moving, that would close a circuit.

It needs to get data from the camera to determine that the camera was
vertical at the time of the exposure. After the fact, it might not be hard
for you to tell, but software would have a hard time.

Canon does this automatically with their cameras and software.

all of them.

there is a slight difference in the way that the Kodak camera does this and
the Canon camera does this (at least the 10D, I don't own any other Canon's)
The Kodak cameras rotate the bits in the image and the image is then defined
as 768x1024 instead of 1024x768 (as an example)
The Canon cameras set a bit in the EXIF header that tells the Canon software
that the image is rotated. If you're not using the Canon software, the
image still comes out sideways.
Each has its advantages and disadvantages, I happen to like the Kodak
solution since ANY software that I use has the image properly oriented.

From the EXIF data in the image.

Some cameras do have an orientation sensor.

See above.

True with some cameras, but not with others. See

Torrex,
Does the zoombrowser only save the vertical images correctly if you download
FROM the camera itself?
Or, can zoombrowser also read the EXIF through a card reader and save the
images in the correct orientation?
I'll try to find my old Canon software disk......somewhere.
Thanks.

I download only through a card reader built in to my PC.
As long as Canons software is being used it works perfectly.
