I used a Nikon D800 equipped with the new Zeiss Otus 55mm f1.4 mounted on a Really Right Stuff PG-02 based panoramic head. This landscape image was captured in the Japanese backcountry early 2014 (Gumma prefecture).

This short essay focuses on 4 samples images generated with my 2 favorite stitching applications, PTGUI Pro (version 10 beta8) and Autopano Giga (version 3.6).

Recent advances in stitching software reducing the overhead, improving the quality of resulting images are opening up new possibilities in terms of situations to which stitching can be applied. The number of frames captured to generate a single resulting image can range from a few to several hundreds or even thousands. The outcome are images that contain a lot more information than a single frame would have (detail, color,…).

While it was impossible to transform an 8×10 camera in a Leica M, nothing prevents you from un-mounting your DSLR from its panoramic head to snap a few frames handheld at ISO 12,800.īut if you think stitching is the way to go for a given image, the technique can be further combined with other images information expansion techniques such as Depth of Field Stacking (DoF Stacking) and High Dynamic Range (HDR). Just like 8×10 doesn’t do everything well and imposes constraints on the shooting experience and subject, the availability of stitching in one’s toolkit should never limit the photographer in his/her shooting freedom. Now, it is also important to know when not to stitch. Stitching helps make images more future proof. Looking into the future, we can also foresee an increase of the quality of display medium, such as very high-resolution screens, for which resolutions higher than those of our current cameras will deliver benefits. The same way that some folks found it rewarding to shoot with 8×10 cameras although medium format film solutions also delivered excellent image quality for most applications, stitching is about going that extra mile from amazing image quality (think IQ280 single frame) to out of this world image quality. My personal answer to this question is “because it’s fun”.
Some may ask “why bother?” when a single D810/a7r frame captured with a good lens and proper technique can yield gorgeous looking A1 prints. Quite a few affordable cameras, such as the Sony a7 mirroless body, do meet these criteria. Generally speaking I would still recommend to use cameras fitted with sensors offering the best possible “pixel quality”, notably in terms of dynamic range and noise. I like to call stitching “the great equalizer”. Even cameras often considered offering only average image quality, such as the Nikon 1 series mirror less bodies, can enable the capture of panoramic images in a few seconds that easily out-do the best 4×5 sheet of film. One major value of stitching is the possibility to reach very high resolutions with cheaper cameras offering a lower native resolution sensor.

Stitching can be done with any type of camera but results are typically best when manual control is available to freeze the exposure and control focus between frames. However the process of stitching can be applied to generate more traditional aspect ratios as well as weird looking polyline bound assemblies of doubtful taste. The best known application of stitching is the creation of panoramic photographs, those wide images comparable to the output of 6×12 or 6×17 cameras, that lend themselves particularly well to many landscape vistas. Somehow stitching helps get rid of the illusion that photography captures reality. I don’t see it as a major issue for those looking at creating art. That may indeed be a problem for those in quest of capturing reality. Some thinkers dispute the photographic nature of stitched images because they don’t capture a single moment in history, but merge several time samples. Would that be any bigger a departure from an ideal capture of reality than our other images with their poor corner sharpness, light fall off, visible chromatic aberrations,…? I happen not to think it would, but stitching defects can sometimes be uglier and don’t quite match our genetic feel for what a photograph must look like. There may be cases when it is difficult to come up with a perfect image devoid of any stitching defects. When not done properly or ingurgitated in prescribed amounts, stitching does carry an element of risk. On the downside, stitching does take a bit more time and doesn’t apply to all types of images. Stitching enables the photographer to produce images in any possible aspect ratio while increasing significantly resolution and reducing the impact of lenses aberrations such as light fall off and reduced corner sharpness.

You may want to pause here for a few seconds, check for allergic skin reactions to the idea of having to spend even more time processing images… It has been known for centuries that digitally assembling a mosaic of adequately captured images is possible thanks to the process called stitching.
