how I use categories on chromasia

All the entries on chromasia are placed into one of seven primary categories: six to reflect the aspect ratio of the image, and the seventh to indicate that an image isn’t available as a print. Additionally, each photograph may be assigned to one of more additional categories or subcategories, e.g. my travel category, children category, and so on.

about the ‘panoramas’ category

This category contains image created with either Photoshop's 'photomerge' facility or Stitcher Unlimited (produced by Realviz).

When I was over in Barcelona last September, at the European Photobloggers meetup, I shot a sequence of 19 images from a high point in Park Guell. Each of the 19 images (shot at 57mm at f/8) were used to construct this image, and the final panorama covers a view of around 320°.

From a technical point of view it was relatively straightforward: the 19 images were shot using a Really Right Stuff BH-55 PCL-1 panning clamp (overlapped by around 30-40%), and then the panorama constructed with PTGui. At full resolution then the final image is 43,195px by 3516px: almost 125 megapixels.

The reason I haven't posted it before is because the small version looks rubbish, even at 1030px wide. With that in mind though I've posted a much bigger version here:


This is 7716px by 533px, and weighs in at 1.8MB, so may take a bit of time to load :)

If you were following chromasia last September you will be able to identify some of the landmarks I shot during my trip. From left to right these are: the power station; the exterior of the Sagrada Familia (an interior HDR is here); the communications tower near the Olympic stadium; and the Torre de Collserola communications tower and the Temple de Sagrat Cor.

So, if you've ever wondered what down-town Barcelona looks like from the top of a hill, now you know :)

I've been meaning to try a panoramic shot for ages and am reasonably pleased with how this has turned out. It was created from seven originals taken at 17mm, using Stitcher. This does a much better job than Photoshop's 'photomerge' function, which is ok for shots with no distortion, but doesn't do a great job with wide angle shots; i.e. there's too much distortion.

Anyway, I'm not entirely convinced that I got the composition right – I probably should have shot the sequence in portrait rather than landscape format, and I think it needs a bit more space on the right – but other than that I think it's probably ok. Let me know what you think.

Oh, and if you're interested, there's a larger version of this image here:
