That's one way of doing it or you could just stretch the original image to fit the 16:9 frame. Nothing in the picture would give away the fact. I do like the fade to night effect.

Unless you are trying to capture a moving subject then synchronising the shutters is not important. LikecI said, I used to just take two pictures, with the same camera, and move it about three inches.

I've only just found hits post from back in June last year. I had a dabble with 3D images about the same time that you did Lin but I actually took two photos of the same subject but moved the camera about 3" between each shot (about the distance oue eyes are set). The method I followed to alter the two images to Red and Cyan was much more complicated than this method (so complicated I can't even remember it). I have viewed this tutorial example with the 3D glases and it is surprisingly good but I dod think that taking two images would produce a better result. I always find it fascinating to watch someone else working in PS as they often do things differently to how I work (like creating a new layer and re-naming it). Moving the image with the arrow keys is a game changer, I have always dragged the image with the mouse and it is very tricky to do acurately. I will try to dig out one of my 3D pitures and post it on here but I've got to go out now.

If I may join in this offshoot of the main topic. I think Barry is mostly right about long AV's but there are a few points to consider. I don't think anyone should try to speak for everyone, only say "in my experience". There is a world of difference between a single person watching a show on a PC or laptop and an audience sitting in a room. It's very easy to stop watching at home and there can easily be distractions. The fact is people sit for up to three HOURS to watch a film. I know films are different o AV's but it does prove that it is possible to keep a viewer glued to the screen for a long time if the content is good. On the down side to long AV's, even if each image was on screen for 10 seconds (which is a long time) then you would need 306 images to make a show of 51 minutes!!!! Certainly my AV's tend to rely on a "trick", like one image slowly being revealed bit by bit, and once the viewer has got it then it can't carry on much over five minutes. At our Camera Club we have one AV competition per season and it is called "Pieces of Eight". Originally it was called that because one member would put eight pieces of music on a cassette tape (that's how long ago it started) and people had to choose one and add their own images. We kept the name, after that idea stopped, and limited each entry to 8 minutes in length.
