To
make a panoramic picture, you need at least 2 pictures that will be
assemble using photomerge. Be sure that all the photos are match when
combined using photomerge.
Here’s a few tips how to ensure you will
get better result when taking a picture for photomerge. Because your
source photographs play a large role in panoramic compositions.
a. Overlap images sufficiently Images should overlap by approximately
25% to 40%. If the overlap is less, Photomerge may not be able to
automatically assemble the panorama. However, keep in mind that the
images shouldn’t overlap too much. If images overlap by 70% or more, it
can be difficult to work with them, and blending may not be as
effective.
Try to keep the individual photos at least somewhat distinct
from each other.
b. Use a consistent focal length Avoid using the zoom feature of your camera while taking your pictures.
c.
Keep the camera level Although Photomerge can process slight rotations
between pictures, a tilt of more than a few degrees can result in errors
when the panorama is assembled. Using a tripod with a rotating head
helps maintain camera alignment and viewpoint. When photographing a
panoramic scene from a high place, the natural inclination is to keep
the horizon level in the viewfinder. However, this actually produces a
noticeable rotation between images. Try using a tripod to keep the
camera level when taking photographs in this situation.
d. Stay in
the same position Try not to change your position as you take a series
of photographs, so that the pictures are from the same viewpoint. Using
the optical viewfinder with the camera held close to the eye helps keep
the viewpoint consistent. Or try using a tripod to keep the camera in
the same place.
e. Avoid using distortion lenses Fish-eye and other distortion lenses can interfere with Photomerge.
f.
Maintain the same exposure Avoid using the flash in some pictures and
not in others. The advanced blending feature in Photomerge helps smooth
out different exposures, but extreme differences make alignment
difficult. Some digital cameras change exposure settings automatically
as you take pictures, so you may need to check your camera settings to
be sure that all the images have the same exposure.
If you already have all the pictures, follow this step to make your panoramic photos:
1. Select File > Automate > Photomerge
2. In the Photomerge
dialog box, click Browse to open all the file you want to merge. Select
Attempt To Automatically Arrange Source Images if you want Photoshop to
try to line the images up in their proper order. Deselect this option if
you want to arrange the images in the lightbox yourself.
3. Click OK when you have open all the file.
4.
Adjust image position by dragging or rotating it if necessary. If you
want to save each image in the composition in individual layers, select
Keep as Layers. (This is useful if you need to correct the color of each
image separately.)
5. Click OK to get the photomerge result.
Note: You can use crop tool to cut the unwanted edge of the picture.
