Combining Images into a Panoramic using Photomerge

Here is another idea we can use to join our PDF files together next to one another


1) Open the images you want to combine. This step isn’t required, but I find it easier and more straightforward to open and view the images prior to merging them.

Below are the two images I am going to merge together. Notice there is a part of the image duplicated in both images. Some duplication within the images aids in merging the photos together.

This opens the dialog box that lets you select the images you want to merge. Since I open the images prior to selecting Photomerge, I select Open Files at this point. If you don’t open the image prior to selecting Photomerge, you can select Browse and navigate to the desired images. You can also select the desired layout on this screen. I usually stick with the Auto layout, but other useful options are available. The interactive option gives you an opportunity to align the images together after Photoshop has aligned them.

After clicking OK in the Photomerge dialog box, Photoshop begins merging the desired images. You will notice several windows flash open, then close again during this process. If Photoshop is unable to merge an image (cannot match up adjacent photos), it will give you a warning message.

When the process is complete, a new window opens with the images merged together.

At this point, I will crop the merged image to delete any extraneous space around the perimeter of the image. The final result is:

As mentioned at the beginning of this article, this process works best with images taken from the same spot and with some duplication in the images. I have used this feature where I did not follow these recommendations and the resulting image is less than satisfactory. It is obviously a merged image with a noticeable ‘line’ where the images come together.

So, when taking your panorama pics use your body as a tripod. Keep one foot firmly planted and rotate your body as you take photos in a 360-degree cirlce. Remember to duplicate at least part of the scene from one image to the next.

What you think comment on it please.
