PowerStitch V1.0 is an extremely powerful program that enables the combining or “stitching” of photographs. These can create either panoramas, such as the one below, or large composite images‚ permitting small format cameras to create images with image quality equaling that from larger formats.

With the advent of digital image processing new capabilities have arisen that simply weren’t possible with traditional darkroom tools. The sophisticated image compositing that PowerStitch is capable of is but one example of this. While there are quite a number of programs available to stitch images together, none has the ability of PowerStitch to effectively remove distortions.

Update: November, 2000

The following announcement has appeared on the Enroute Software web site. This is a shame, and it means that if you would like to purchase a copy of this exceptional software you’d better do so soon, since I know of no comparable alternative.

An Example

A personal project of mine is photographing sunsets from the deck of my country place on Lake Muskoka in Ontario, Canada. Not necessarily great art, but enjoyable nonetheless. I’ve always been frustrated by being limited in my ability to capture the span of this and similar vistas. Even a camera like the XPan doesn’t give the right combination of reach and breadth. A wide angle lens alone would simply make the subject smaller. What’s needed is a combined telephoto / wide angle capability. PowerStitch permits this, and a whole lot more.

Clicking on this image will display a 17″ wide version. It’s worth viewing to appreciate the resolution and detail made possible with this technique.
A 1280 X 762 display is needed to view this image without scrolling.

This photograph is made up of 4 horizontal 35mm frames. When taken, each was overlapped with the other by approximately 50%. Each scan was approximately 35MB in size and were produced with an Imacon FlexTight scanner at 3,200 DPI. The final combined file, after rendering and cropping is 95MB. This is big enough to make a print 3 feet wide at 300 DPI. 

Photographed with a Canon EOS-1V and 100~400mm IS lens @ 100mm on Provia 100F, comprising 4 frames composited in PowerStitch.

Digital Darning

PowerStitch provides a powerful yet intuitive user interface. Images to be stitched are loaded into what appears to be a 3-D workspace. Groupings of tools allow each image to be moved on a grid and aligned with each other. This is a manual process and it’s worth taking the time to get the positioning and other parameters correct. Rather than being tedious, it’s fun. As I was learning the program using the 4 files in the example above, I found that they could all be critically aligned within less than 15 minutes.

Once the files have been aligned by hand a quick preview run is done to test how it looks. This takes less than 1 minute. Once you’re satisfied with the effect the files need to beRendered. The program told me that these 4 – 35MB files would take 75 minutes to render into a single composite image. On my 600Mz Pentium III with 762MB of RAM it took 25 minutes.

The result, as seen above, is essentially perfect. There are absolutely no distortions of any kind and there is nothing that indicates that this photograph is a blending of 4 separate images‚ even when critically examined in PhotoShop at actual pixels resolution.


This is an expensive program at $399.00 U.S. You have to be serious about doing this type of photography to lay out this much money for utility software. On the other hand, if you need it‚ there’s nothing else on the market with this much power. It’s thePhotoShopof stitching programs.

Here are the hardware requirements:


Pentium (or 100% Compatible) Processor


Windows 98/98SE


DirectX 6.1




Hardware Direct3D acceleration


Free Disk Space = 5 x uncompressed total input image size.

Note the disk space requirement. 4 – 25MB images in a composite would need 500MB of free disk space while the program is working on the file. This is a processor and disk intensive program to say the least! The final file will end up as being somewhat less than 100MB in size, (using this example)‚ still quite large. Don’t create files bigger than what you can subsequently load into your favourite image editing software.

Here are the graphic cards that are currently (July, 2000) supported.This is very important. You must  have an AGP capable video card. If you do not have one of these cards, the programwill notwork!

Another Example

Wahcella Falls, © 2000 Jonathan Sachs

This enchanting photograph is another example created with PowerStitch Jonathan Sachs.

It was created from two images shot with a Pentax 6×7 camera using the Pentax 165mm lens. The two images were scanned at 1600 dpi using an Imacon FlexTight Photo scanner, yielding roughly 40MB files. They were combined using rectilinear perspective. The waterfall is Wahcella Falls along the Columbia River Gorge in Oregon.

Shooting with PowerStitch in Mind

Of course you need to avoid anything that moves between frames. A car, plane or person that appears in two separate places in a scene is a bit difficult to explain away, though it can likely be cloned out in PhotoShop afterward.

It is suggested that you shoot vertical frames, since these will help minimize angular distortion. (The program does a great job in correcting such distortions, but it produces the best results if you give it all the help that you can beforehand.)

You should also expose each frame of the composite with the same exposure and avoid using a polarizer‚ otherwise the sky will appear very uneven. A split neutral density filter will work, but don’t change its position between frames.

When scanning, similarly don’t change the scanner settings between scans. Also, trim each frame so that there are no black borders before loading them into PowerStitch.

It should also be stated that PowerStitch can also be used with original files from digital cameras‚ not just scanned transparencies and negatives. When used this way its ability to create distortion-free composite images can be very powerful, and useful in overcoming the resolution limitations of current equipment.

Field of View

To do its distortion correction job properly the program requires that manual alignment of each picture comprising the composite be done with the program set to thehorizontalfield of view for the focal length of the lens used. In other words, if you took the sequence of shots with a 50mm lens on a 35mm camera then you want to set the program’sField of Viewcontrol to about 40 degrees while doing preliminary alignment.

I’m surprised that the developers of PowerStitch didn’t provide a calculator for this since it isn’t a number that most people are aware of. You could always look these up from manufacturers literature, but that’s tedious.

Here are the numbers for the lenses that I use. If you want you can go online and use Rui Salgueiro’s Field-of-View Calculatorto calculate your own.

What’s The Fuss?

As the first edition of this review is written (July 2000) there are a couple of reviews of PowerStitch that have appeared in print. One is in Outdoor Photographer (Aug., 2000) and the other inGeorge Lepp’s The Natural Image, (Vol. 16, No.1). This edition of George’s very fine journal focuses on Panoramics, and contains a wealth of information on various camera systems and other products related to panoramic photography. Both of these magazines have hyperlinks that can be found on my LINKS page.


May, 2001

Though PowerStitch is now defunct there are many other perfectly adequate programs for stitching panoramics. In fact most digital cameras now come with such software included somewhere on their installation CD. The examples below therefore could easily have been done with any of these programs.

Arno, Florence: May 2001

Photographed with a Canon D30 and 28~135mm f/3.5L IS lens at ISO 100

This photograph of the south bank of the Arno River as it runs through Florence, Italy was taken from my hotel balcony. It was just before sunset and the muted colours nicely match the feel of the city’s palette.

Three frames shot at about a 35mm focal length were used, and were overlapped when shooting by about 30%.

Arno, Florence: May 2001

Photographed with a Canon D30 and 28~135mm f/3.5L IS lens at ISO 100

Though only 3 frames were used in the first image above I actually shot a 7 frame sequence covering 180 degrees. This photograph was stitched from all seven frames. While it’s fun it is really too wide, and the perspective is consequently confusing.

If you click on it to see a larger image you will have to scroll to see the whole thing as that version is about 15″ wide.

These photographs are part of a small series taken in May, 2001 in Florence, Rome and Tuscany.
