I should mention that I am importing the images from my camera into Bridge.

Are you importing into a local drive on your puter?  You should.

FWIW.  One of my intense pet peeves... is seeing people taking photographs portrait mode!  Especially 16:9.

I just dont get it compositionally or practically and if the shots are intended for "video"...less so..

I tend to watch movies and TV etc on my couch... sitting on the right hand side ( camera right ) of couch.

If all of a sudden the stuff I'm watching gets horizontal I simply lay down on my left side and put my head on pillow and relax.

So I can watch stuff like this basically with my head rotated 90 degrees to the left ( camera left ) 90 degrees.

Then if the images get right side up again and were shot correctly etc..I can just sit up on my couch to normal position again.

The alternative is to get up off couch and turn the TV sideways.. which is way more work for me than just laying down.

Just some ideas I'm throwing out here...

Well, one good thing about going sideways... a lot of art critics think that if you can turn an image around on its axis ( sideways, upside down etc ) and the "composition " still looks cool.. than the picture is very good.

There's always a silver lining.

Bill, you're absolutely right and I was remiss in my first response above.  I checked some of my folders and in one of the first folders from several years ago Windows Explorer displays photos as both portrait and landscape.  I used the camera's software to import the photos but I don't recall whether I also rotated them in Explorer or if I was on a different OS (probably a different OS).  In any case with newer photos from only about 1 month ago I see that Explorer only displays the images in landscape orientation, although some of the pics were clearly oriented as portrait when I took them with the camera.  And I'm sure in the camera's software they are rotated.  Go figure.  I can't explain the difference between the old photos and the new ones and how they are displaying in Windows Explorer.

my only point in answering the question of the OP was to answer how to adjust rotation and it seems i had the wrong answer to begin with.  you're probably right about everything aesthetically speaking concerning landscape and video though.  i don't really work in video but saw this question in my rss and decided to enter the discussion.  perhaps i should have strayed away but the question was geared towards bridge, photoshop, still images, etc. and i do on occasion take stills.  no worries.

I didn't think of Picture in Picture either but that could be a good use.

What I was thinking of is all the people I see on the subway with their iOS devices shooting video in portrait orientation.  And shooting stills that way.  If they wanted to make a linear slideshow of their captures in Premiere then I could see the point of this discussion.

Do you get beaten up very often Jim?
