[putri]

when im tilting the camera upwards to get more sky in a landscape..is it neccasry to correct

the front an back to make it parrellel and perpendicular t the groud?? when do i do it?

Yes - the best option (if your camera allows it) is to use front rise. Either way I recommend that you do it early, because you've precisely focused.

It is not necessary, it is an artistic decision about how you want the photograph to look. It is a convention of Western European art / perspective for centuries that perspective be rendered with a frame that is plumb (perpendicular) to the ground. Deviating from this rule is most noticable if there are elements in the photo with vertical lines, such as buildings. But this "rule" is merely a convention, not a law of nature. If you like the photo better with the back not plumb to the ground, then the back doesn't need to be plumb to the ground. The convention has been weakened by people's experience with photos from handheld cameras, which are commonly tilted to capture the desired portions of the scene.

 

As Jean-Batiste says, front rise is the fastest way, and before final focusing is the time to establish your composition. If you run out of front rise, then you can tilt your camera upwards, then use tilt to bring both standards back to plumb.

Depends. If what you want is an undistorted photograph, then you would want to level and plumb the film plane. This will, for example, keep the vertical lines of the trees or buildings straight and perpendicular as they are in real life. If the film plane is tilted, you often get "keystoning" where the trees seem to bend and the tree tops move toward the centerline of the film. Leveling and plumbing the film plane in landscape work is very often accompanied by using front rise (to get the tops of the trees in the image).

 

One place where you might not want a level and plumb film plane in landscape work is with a near-far composition. For example, a stream with a rock near you (bottom of image) with ice in the stream farther away (at the top of the image). In this case, you might want to tilt the film plane back (top toward you). This distorts the image, but in a "good way" as it makes the foreground rock "loom larger" in the image. This technique was a favorite of Fred Picker, who loved to wander around icy streams in the New England USA winter looking for these types of compositions.

 

In other words, use the camera movements to make the artistic statement you want to make.
