The software used is Photoshop's own photomerge. It covers the practical problems - keep the camera steady and level, use a spirit level - and the problems of the different types of geometry you can target and the distortions that can ruin a panorama.

However this is a better discussion of the problems and techniques than most. Many of the images presented are clearly remarkable and not achievable using a single shot technique without unfeasibly high lighting levels!Ĭhapter 5 is about the reasonably well known topic - image stitching. Of all the chapters in the book this is the one that made me want to get my camera out and try to create something different. When we do get to some automated help the tool is PhotoAcute again, Combine ZM and Helicon Focus. This is one of the best chapters in the book because the theory is well explained and issues such as determining the optimum aperture setting to use are dealt with in practical detail.

This is one technique that it is possible to use manual methods and indeed the authors show how to manually stack exposures to select areas that are in focus to show through. The following chapter moves in the fascinating area of combining multiple shots to increase the depth of field.

The technique can also be used to decrease noise, by averaging and hence allow you to take pictures at a higher ISO and the merits of this are discussed. I'm not convinced that this is necessary as the software is fairly self explanatory. The resolution increasing software used in the tutorial is PhotoAcute and the book takes you almost click-by-click through using it. It might have been better to treat both topics together in one chapter and discuss their relative merits. The alternative way of achieving the same result is to stitch together a panorama and this is discussed much later in the book. The basic idea is that you can use averaging and interpolation from a set of shots of the same scene to increase the effective number of pixels and reduce noise. Next we have a discussion of the typical workflow in a multishot session - which camera, which file formats, some basic tools, what are the problems and so on.Ĭhapter 3 brings us to our first technique - super resolution. In fact quite a few of the shots were less than perfect - but overall the lack of perfection was slightly reassuring! I wasn't always convinced that the presented effects were worth the effort, but they mostly go to show that multishot technique brings about an improvement. The book starts off with an overview of the different multishot techniques you might want to use and offers small examples of what you can achieve. It also isn't DIY multishot and there are no suggestions or hints on how you might write your own utility to do the job. The first thing to say is that it mainly uses Photoshop as its editing tool and it isn't apologetic about using commercial software - so this isn't really multishot on the cheap. You can't really say that the techniques described in this book are fully developed as yet - there is plenty of scope for innovation and creativity.

You could imagine doing some of the tricks in the traditional darkroom but multishot is really only possible with a digital camera. Multishot techniques are a way of pushing the camera, and even basic imaging physics, beyond what is normally possible.
