Creating panorama shots in Photoshop CS3

Petra Tou Roumio, Cyprus, birthplace of Aphrodite

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.

Photos published in Schmap travel guides

I've had significant response from my Flickr photo account, with people contacting me to use photos for publication or as part of projects.

Today, I've heard from Schmap dynamic travel guides. Several of my photos, uploaded to Flickr and published under a Creative Commons licence, are being used in their guides to Paris and Florence.

I've downloaded the player and find that it's a well-integrated online map guide to hotels, restaurants, attractions, bars, museums, gardens etc to all sorts of places all over the world. Try it out.

Learning photography with the Canon EOS

I was inspired by the hype surrounding the release of an affordable digital SLR camera to go out and buy a Canon EOS 300D model early in 2004. I'd used Canon film cameras in Oman, which had come highly recommended, and decided to advance with technology.

I took the camera with me on a trip to Oman in March 2004. See the photos of Musandam, Iranian smugglers and Dubai at Oman Vistas. I was very pleased with the quality and the resolution although it seemed to me that the camera tended to underexpose shots.

It was only when I was actually in Musandam trying to take a photo of a kingfisher with my Sigma telephoto lens, which had worked perfectly well with my Canon EOS film camera, that I realised that there could be compatibility issues. The lens proved to be temperamental and although I managed to use it to take close-ups of the family at cricket in the 2005 season, I could not rely on it.

This year, I've had requests to use several of my photos on various of my websites, taken variously with a Pentax Optio 430 – see the Muscat, Grand Mosque and Nakhl folders at Oman Vistas, and a Nikon Coolpix 7900 – see my photos at Flickr – as well as the Canon EOS 300D. Although the Nikon claims to have a higher resolution than the Canon, at something like 7.3 megapixels per inch, plus it's small, compact and very handy, I couldn't get over the image quality produced by the Canon.

I felt it was time to develop my photography skills. After all, there's no point in having an expensive camera if you don't know how to use its full potential. Besides, I could see a market in selling my best photos on the web.

Canon outsources its training and information services in the UK respectively to Experience-Seminars and EOS magazine. I booked three courses held over three days last week on 'Making the Most of Your EOS' held at the Huntingdon training centre.

Initially, I was dubious about the cost. It seemed a little absurd to pay almost half as much again as the original cost of the camera body to learn what I should probably have been able to learn from the manual – but I learnt a great deal more than just how to use my camera. I also learnt basic photographic skills – shutter speed, aperture adjustment, depth of field, metering, how to use flash, and also some very basic Photoshop techniques which can bring out the most in a photograph. This is because the trainer is a professional photographer with years of experience.

And yes. Canon cameras work best with other Canon accessories and peripherals. Use dedicated Canon lenses and Canon printers to get the optimum results.

It didn't take long to work out that not only was my 300D now obsolete, but it was also the bottom of the range. Amongst those cameras brought to the seminars last week were four or five EOS 5Ds, which will set you back over £2,000, without the lenses and speedlites.

One lady, who is going on safari to Zambia in October, had brought her new EOS 350D, which impressed me with its smaller, lighter size.

The biggest problem that I could see with the 300D was its slowness. It takes four seconds to bring the camera out of sleep mode to take a photo, by which time, the photo opportunity has passed. This is particularly galling for sports and action photos because the camera takes so long to record to memory before another photo can be taken.

Thus I have been sufficiently motivated to upgrade to the new EOS 400D with 10 megapixels, virtually all the other settings offered by the more expensive cameras and a more compact size to boot. It's also costing less than what I paid for the 300D back in 2004.

As an example of what I learnt, here are three photos of an orchid taken with flash, all in P mode with ISO set at 400. One is taken with evaluative metering in full flash, another with partial metering in full flash and the third with partial metering in bounce flash. Unfortunately, I was still suffering from problems of underexposure by the camera – which I shall have to investigate – but I was able to redeem my errors by adjusting levels in Photoshop.

The third photo is by far the best. You see the petals of the orchids as you would if you looked at them in reality. Both the other two photos exhibit what I would call 'pearlisation' on the petals, which gives a false result. This is due to burnout (overexposure) on disparate details by the flash. The second photo displays total burnout in one area on one of the petals.

It's when you can see the visible results of what you have learnt and the added confidence that brings, that would make me thoroughly recommend this training.
