Complete newbie question. Whenever I've tried to stitch shots together I can never get them to line up properly.
If I get the lake bed correct, then the tree tops are off etc.
How do you get around this? Is it just because I've used a crappy camera with a lot of lens distortion? Or because I'm swaying too much as I pivot?
Thanks
The best way to do it is to
1) Use a tripod if possible (if this is not possible then try and rest the camera on someting)
2) Make sure you are using at least a 50 mm focal length so that you don't get barrel distortion (Zoom the camera so that it is about half way between wide angle and telephoto if you have a point and shoot)
3) lock the exposure settings and focal length, so that it should fit together nicely
3) try to make sure that the right and left 3rd of you image is also covered by the images either side, though this doesn't have to be obeyed, bascally you want some overlap and to avoid having to join on complex parts, it also means that you have room to crop or delete bits from the edge of an image
Then if your using photoshop
4) Stitching together I find is usally quickest and easiest manually in photoshop. you can use the perspective and distort transform tools to line up any problems at the edges, though if you follow 2) then these shouldn't be to much of a problem, especially if you crop some of the side of each image.
5) To "blend" one image to the next. Firstly I import each image as a seperate layer in photoshop,
6) Align them by eye, and then create a new layer mask for each layer
7) Using the gradient tool from white to black, drag the gradient along the part where the two images join (you must be doing this in the newly created layer mask)
8) To tidy the image up you can use the balck or white paint brush on the layer mask to select parts form the top or bottom images respectively
