Why do you stitch images together?

When you want to print enlargements of digital images, there's usually a point where the image quality will suffer as the print size gets larger. That's because digital images are made up of lots of dots called pixels, and these pixels need to be printed very close together so that the human eye can't distinguish them. As you enlarge the print size, the pixels have to be printed larger and larger. Sooner or later, the pixels become visible on close inspection and the image looks 'blocky' and loses definition.

The same is true to a certain extent with images taken with traditional film cameras - but instead of pixels being the limiting factor, it's the film grain. The general principle, then, is that any image has a limiting size at which it will lose quality when printed.

So what's the answer? You guessed it - stitch multiple images together. This means you can print at much larger sizes without increasing the size of the printed pixels, thereby maintaining maximum image quality.

Another good reason for stitching images together is so that you can extend the field of view contained in the image.

How do you make the seams invisible between stitched images?

This is the skill of the photographer and digital post-processing artist!

Firstly, the source images have to be taken very carefully to achieve the best results. Special attention must be paid to maintain consistent exposure across all frames, and the geometrical positioning and alignment of the camera has to follow specific rules in order to avoid 'parallax errors' (changes in the alignment of near and far objects between frames). Some overlap must exist between adjacent frames to assist with the subsequent stitching.

Secondly, the frames have to be blended so that they form one seamless image. This is enormously difficult to do manually, so specialist software has been developed to carry out this task. However, using the software is an artform in itself - it can produce fantastic results, but there's a steep learning curve and it requires lots of trial and error. But that's all part of the fun!

It has to be said that you can create acceptable results using a hand-held consumer camera and manual stitching. In fact I've seen some superb panoramas created this way. However, creating high resolution panoramas like this would be extremely difficult at best (if not impossible), and the time taken to complete a project would be much increased.

Can I use one of your images in my website/magazine/poster/etc?

Yes - all my images are available for commercial use. Simply enter your details on this form, including how you intend to use the image (where it will be published/displayed, for how long, for what purpose, any branding to be applied, whether photographer's credits may be included, etc), and I'll reply personally with a quotation. All quotations are based on the individual circumstances of the client and vary depending on the intended use (this is standard practise in photographic buying).
