The order you take the images in is not important as long as you keep the right and left straight.
The distance you move the camera is up to you ;but, a hint is that for close objects use a small distance
and for distance objects use a larger distance.  Experiment! There is an art to it.

    If you can get the camera video directly to Snappy, you could use the high resolution mode for much better results. In the full motion mode, if you had a very still field and camera you might get better looking resolution by using the the high resolution mode with the tape running (several seconds).

Step 2: Make digital copies with the Snappy.
 
 

Step 3:Combine the two images
Quit Snappy and load Adobe Photodelux (comes with Snappy). Load the right image and make it a hold file. Load the left image. Click Hold Photo and double click the right image, click Lighten under Blend then OK. The next step is a little tricky.
Step 4: Alignment
     Alignment of the two images is almost always necessary.  By aligning just right you can make the image depth in the page change from into the page to outside the page.

To align the images  make the bottom or top layer the active layer.
     Goto "Modify On Your Own" and capture the entire layer by clicking Copy . Move the active layer by clicking the left mouse and holding  it down  inside the view . Moving the mouse will move that layer while leaving the other still. Move it some and check by letting up on the left mouse and view it with 3D glasses. If it does not look correct, move it some more untill it appears to be the correct position for best 3D.
  Upper left to lower right.
     When you think it is correct, click one time in the view area and the movement is finished.
     This step is tricky but, if you mess up,nothing is lost; just deleat that layer and reload it. Keep trying untill it looks best to you.
     If nothing seems to make the combined image look 3D, try turning your glasses around so that the red is on the right and blue on the left.  If that works you have the left and right reversed. I know because I have done it.
     You can crop off the edges that are left and export (instead of save) the resulting 3D image as a jpg or gif image to use on a web page.

Final version after croped and exported as a jpg.

     You need to know how to use Adobe Photodelux  to use this method. It is the perfect program for making anaglyphs. The only thing I have not been able to do with it is remove the red or green-blue correctly. Fortunately Snappy Adjust does this perfectly.
     Best results are achieved with higher resolution graphics like tif or bmp even, but the file sizes get really big. Also, if you save the two original views in a high resolution mode, you can go back to reprocess them as you get better at processing.

     The nice thing about Snappy 3D is that you can see the results in a few minutes and the cost, once you have the computer and snappy, is very cheap per picture. The obvious drawback is that the resolution is not photo quality, but it is better than TV quality and almost everyone is used to that.  Like I said, this method is an art.

     I have tried to make these instructions as easy to follow as possible.  If anything is still unclear, let me know.
