How to shoot panorama photo? What kind of lens should I use for making a panorama photo? Shouldn't I use 17 mm? I tried to shoot some panorama photo with my 17 - 35mm lens. However, I am thinking that I probably shouldn't use 17 mm for panorama photo due to the "distortion" of the image. Should I just use a normal lens for shooting panorama photo? I have already taken a few using my 17 mm lens in my recent trip and would really want to know if I can join them together to form a panorama photo. Also it would be great if someone can share the technique with me. I use the same exprosure for each photos and simply taking each photo from left to right by just rotating my tripod 3-way head. Should I always be level with the image? I mean not to tilt my camera in order to get "stright" horizontal line? Or is it ok to tilt the head? Also, I would like to know if I can use photoshop for creating the panorama photo? How? Thank you very much.

You can use photoshop. There are programs I've seen where they correct angled cameras or lens distortions, also. For example, iVista Panorama. Ariel

Ariel, thank you for your kind response. Sounds like that I shouldn't tilt the camera and use a 17 mm len although software is so powerful to correct these problem, right? Thank you,

Ella, Ariel is correct that software can be used to correct those problems, but it would be easier if you do what you can in-camera to prevent them. If your lens creates barrel distortion at 17mm, then it would make things easier if you zoom a bit until the distortion is corrected. You probably don't need to switch to a different lens, I would bet that the lens only has the distortion problem at the extreme wide end. The tilt question depends on what kind of tripod head you have and how you are tilting the camera. You can tilt the camera to get a straight horizon, as long as the panning motion turns on that tilted axis. In other words, if you tilt the camera, but the panning motion is still level with the ground you are standing on, then the stitching will be harder and you'll have to crop more to get a straight picture. It might be easier to keep the camera straight in relation to your tripod, and straighten your horizon by adjusting one of the legs of your tripod. Chris A. Vedros

Lens distortion should only be very obvious at the edges of your photo, Ella, and that won't be a problem if you are taking pictures that are intended for stitching later, because you won't need them! There should be an significant overlap between the frames: 30%-50% works best, so except for the extreme left and right sides, the edges won't show and you can allow extra width left and right to allow for cropping these. A tripod is helpful, but not essential, and you should use a reference point like the horizon to keep the frames in the same plane; in other words, yes, you should level the horizon for each shot. If you do use a tripod, remember that it pans around a point near the film/sensor plane, which is NOT ideal. Instead, you should be rotating the camera around the point in the lens where the light rays cross over. On you 17-35mm this is roughly where the lens fits to the camera body. You can buy panorama brackets for your tripod to do this (but they can be pricey). You were right to keep the same exposure throughout. It makes merging the images easier later since the differences in light and shade across the image haven't been cancelled out by the camera adjustments. The easiest way to merge the images in a programme like Photoshop is to use the Photostitch tool ( think it is most versions), but you can use Layers easily enough.

Thank you very much, David. I have never know it is not ideal to pan on a tripod with a regular 3-way pan head. Even if it is not ideal, can I still do so? I don't want to spend mony to buy the bracket until I have enough technique to take the photo. Anyway, I am really appreciated your advice and help. Thank you.

Yes, Ella, you can do well enough with a standard pan head.
