Creating panorama shots in Photoshop CS3

Petra Tou Roumio, Cyprus, birthplace of Aphrodite

When I can’t decide on a creative issue on a website, or if I have to write something, I procrastinate. Don’t you? This morning, my procrastination led me to review the photos I’d taken while on holiday in Paphos, Cyprus, in April last year. I rather fancied the idea of entering the Creative Challenge at Webshots Blog and thought there might be something suitable in the Paphos folder, but there isn’t. I had a very handy, small Nikon camera with me on holiday, but the light was very bright in Cyprus and the camera tended to over-expose.

However, I thought I’d try making a panoramic shot of Petra tou Roumio Bay in Photoshop CS3. The individual photos aren’t anything to shout about, but the view as a whole is breathtaking. Photoshop has enabled its users to assemble panoramic montages in several earlier versions, and has provided more scope with this facility in its latest CS3 rendition.

Open Photoshop. Go to File > Automate > Photomerge. A dialog box opens offering you five editing options, depending on how much control you want to take over the process. There’s Auto, Perspective, Cylindrical, Reposition Only and Interactive Layout. Rather than my trying to explain what each of these options do, I think you would get a more intuitive grasp by going through the process. You are able to choose the photos that you want to include, either by having them already open in Photoshop, or in a folder, or by using Control + Click on a PC (presumably Apple key + Click on a Mac) on the particular files within a folder.

Make sure that there is an identifiable feature at the edge of each photo which can be matched to the next one, and you should have taken each of the photos with the same camera settings from the same spot for the process to work most smoothly.

Click OK and Photoshop goes into action building the panorama. Depending on the amount of RAM in your computer and how big each individual photo file is, this could take seconds or minutes. I have a lot of RAM on my PC, but it still took at least 10 seconds to build my panorama of Petra tou Roumio.

The delay might have been caused by the fact that Photoshop simply couldn’t match one of the photos at one end. There wasn’t enough of the recognisable feature for the program to work on. In this case, I cropped and saved the panorama image as a psd file, then expanded the canvas, making sure to stretch it to the right, added a new layer, opened the offending photo, selected and copied it, and then pasted it into the new layer in the panorama.

It wasn’t a perfect match but the clone tool used on the top layer helped me smooth out the obvious joins. Since most of the join was sky and sea, this was fairly easy. You’d have a hard time of it with something detailed. Alternate between the underlying panorama image and the top layer to adjust your clone tool settings. Then I cropped the photo once more.

I had to resize the image and save it for the web to be sure that it wouldn’t overload bandwidth and might actually have a chance of displaying in its entirety on a web page. Click on the image above and it should open in a pop-up box.

What’s the story behind Petra tou Roumio? Cyprus has been a centre for the worship of Aphrodite and fertility and her earlier incarnations since even before Greek times. There’s a magical quality about the light at Petra tou Roumio, which lies at the southwestern point of the island. The bay is backed by white chalk cliffs. The whiteness of the chalk stretching under the sea gives the colour of the water a milky quality and also enhances the blue. The light is very bright.

The legend is that Aphrodite/Venus rose out of the sea here at the rocks, where the seed of her father Uranus fell into the ocean. For a most wonderful representation in art, see the Botticelli painting held in the Uffici Gallery in Florence, Italy.
