Hi,

I just tried to add my images to MC 12, and noticed some of my pictures was rotated wrong. I am pretty sure these had earlier been fixed by rotating them in Windows image viewer (that buildt in one...). E.g. when I clicked the image, and chose rotate left, the image rotated 180 degrees (aka pi for those who preffer radians ). Then when I rotated it back, it came out correct, rotating it 90 degrees backwards.

Does the Windows Image writer "physically" rotate the image, or just mark it's rotation?

[Mr ChriZ]

The windows image rotation physically rotates them,
however it totally disregards the tag information the
camera has provided as far as I know.
It could be therefore that the rotation tag information
from the camera is left in there, and then when
MC reads them you end up with an image
rotated the wrong way...

Rotate them in MC to the correct orientation.
MC's image rotation is lossless, so you've got nothing to worry about.
Be careful using window's rotate function - you can lose quality!

MC12 will also reset the orientation field in the image file so that the files will display correctly in other programs.

[Mr ChriZ]

Still would love a Rotate 0 Degree's function in MC
which would just rotate the file physically to the correct
orientation, and remove the rotation tag data!

[Matt]

MC 12 does remove the EXIF rotation data when rotating.  So rotate until they're correct with MC, and then they should be correct everywhere.

MC 12 also supports EXIF rotation (imported to "Rotation" database field) so that images will be auto-rotated when importing from most modern cameras.

Due to these improvements over MC 11, some images rotated with MC 11 may need an extra nudge with MC 12.  This is a one time thing.

[Mr ChriZ]

ah but if they're already correct with MC then it won't remove the
EXIF data, and in applications that don't read the EXIF data
the images are the wrong way up.
If I could select all my images and tell MC to rotate the images 0 degrees,
that would be funky!
I guess I could tell it to rotate 90 degrees one way then 90 degrees the other
but on a library of 5 gigs worth of files... that could take some time!

[darichman]

So all you have to do is rotate left then rotate right (so you're back where you started) and MC will have wiped the orientation field! The image will display the rioght way up everywhere.

Like Matt said, you only have to do this once for files you had previously imported into MC, as MC didn't start reading EXIF properly until MC12

[Matt]

The first rotate may rotate differently than expected.  This is because the image goes one way, but the EXIF is also cleared which could cause it to go the other way.

However, simply keep rotating until it's the right way up and you'll be good to go anywhere.
