The method that has been used for a long time is that of taking several overlapping pictures and then "stitching" them together to make one long (or indeed high) picture. For this method, it is important that the setting on the camera is not changed between shots. Also a steady hand (or a tripod) is needed to ensure that the pictures are level with each other. Most of our members used Photoshop Elements to stitch the pictures together, although there are several alternatives. One or two examples of this method are shown here.
One of the potential problems is that after stitching, not all areas round the edge are filled in. Elements will offer to fill these for you, but if there are a lot of pictures to stitch there may be a memory shortage problem. Bob's picture illustrates the blank areas, although it is not necessarily a draw-back. You can also crop the picture to remove the blank spots, provided that you don't thereby lose too much of the picture.
Frances accidentally changed her camera setting between shots. Fortunately it does not seem to have adversely affected the final panorama.
Ingrid demonstrated that the picture does not have to ba landscape view.
Marthe had a very large number (11) of shots to stitch.
Sonia's picture was of a skiing travelator "magic carpet". The problem here was the risk of people appearing twice in the final result! She used the camera's "Stitch-assist" setting which ensures the pictures overlap appropriately.
