Panoramas - part 2 of 1 2

Published 01/03/2003

Output

Long thin pans look a little weedy on A4 paper. Epson make a panorama paper (which is an option in your "paper size") or you can use the roll feed on a modern printer. We output the examples three-up onto 24" paper on an Epson 7600, running off the roll at more than 5 feet.

Panorama

1. The two images to be stitched. The illumination fall-off is equal on both images at the matching ends.

2. The white remnant of the scan is first trimmed off with the Erase tool to show a definite edge.

3. Aligning the images now reveals the change in image density across the join line.

4. A Curves Adjustment Layer is added to the right hand image (uppermost on the layer stack).

5. The curve is adjusted so that the join line blends into the tone of the image below. This also lowers the tone of the whole of the right-hand part of the image, which is not desired.

6. A gradient is applied to the layer mask associated with the Curves Adjustment layer. This leaves the left hand part of the image matching at the join but leaves the remainder of the image to the right un-altered.

7. The image tones are now balanced up.

8. To control the blend of the image structure (i.e. the building detail), a Reveal All Layer Mask is added and a gradient is dragged between the guides, which mark the ends of the images.

9. The completed stitch is seamless both in tone and structural detail. Distortion of the image by the taking lens is accommodated by painting the mask so that only one version of the building structure is allowed to show in the composite image. This was true of the Radio City Tower.
