The joy of 'stitch': David Noton on creating multi-image landscapes with the Canon EOS R

Sometimes, one image just isn't enough. Photographers have been creating composites and collages since the 19th century, but today's post-capture software allows for the seamless 'stitching' of multiple images to create one incredibly detailed digital file, with the possibility to print at enormous sizes.

Award-winning British landscape photographer David Noton is renowned for creating beautifully-crafted 'stitched' images. He's particularly famed for his 'letterbox-format' panoramic scenes of landscapes around the world. For his latest project, however, David has been making images that combine more than 20 single photographs, which gives both incredible resolution and tonal range. "To shoot these images, I had to dig deep and learn to do things I haven't done before," the Canon Ambassador says. "So it was challenging."

Shooting with the EOS R

Because he was shooting lots of images of a scene, each individual photo had to have a narrow angle of view, so he used lenses with longer focal lengths. Together they combined to make wide, hugely detailed landscapes.

Each final image was made up of around 21 different shots – for horizontal images, David would shoot three rows of seven shots and for verticals he'd shoot seven rows of three. One of the challenges of shooting a composite image in this way is the length of time it takes. Photographing a landscape at exactly the right moment, in the ideal lighting conditions, is central to David's work. But when he was shooting multiple images, the light would sometimes change significantly during the time he was shooting the sequence.

"There's always one moment when the light's at its best, so I would get to my location and have it all scouted and know what I was doing," he says. "Then, when the light started getting good, I'd begin working on my sequences, using manual mode and keeping the exposure the same across the frame. I would do quite a few sequences as the light evolved, to make sure I had captured it when the light was at its best."

As well as choosing the best time to shoot, David had to tackle the variation in light across the whole of the frame. "Getting the exposure right is really difficult and you have to meter from the middle of the scene," David says. "But it does help if you've got a camera such as the EOS R that offers good shadow and highlight retention. Then, in post-production, you can bring out detail in the darkest shadows or brightest highlights in the frame."

Variation in light was less of a problem on the night shoot, but photographing in those conditions was even more time-consuming. "The trouble with the night shoot was that the actual exposures were something like 30 seconds each," he says. "So if you're doing 21 frames at 30 seconds each, taking into account the time you're spending re-composing, it takes around 20 minutes for each sequence."

David's image stitching tips

David says the key to shooting successful stitched images is to be methodical in preparation but as quick as possible in execution. "You have to go to the location to do a test run beforehand. Get your tripod so it's rotating dead level, because a wonky horizon will stand out horribly," he advises.

"Then work out your framing based on doing overlapped images. You need to work on the basis that you've got to give yourself more frames than you need. You can always crop the image down. So although the images I shot were based on something like 21 images stitched together, I was doing more. This allowed me to fine-tune the crop subsequently in post-production using PTGui Pro software.

"You've got to be meticulous with the way you work, but you've also got to work fast because light is changing as you make the exposures. With all 'stitches' it's all about pre-visualisation because you can't see the finished product through the camera. You need to have the end result in your mind from the outset."

Printing the image

The wealth of detail offered by stitched landscapes is best appreciated in large format prints, such as those produced by Canon's imagePROGRAF PRO-4000 printer. David's image files from the Canon EOS R, processed through Canon's Digital Photo Professional software, were further enhanced using Canon's new print software solution Professional Print & Layout. It includes the DPRAW print function, which enables high-definition printing, and the HDR print function, which allows for the adjustment of highlight areas in high-contrast images.

"I was able to use this software to pull back highlight information, even blown highlights, and enhance the tonal range of the prints," he says. "The difference between the 'before' and 'after' images was like night and day. The end result was a print that had incredible detail and clarity, partly because of the number of images used to make it, but also because the tonal range is really impressive."

David says that when he sees the final product it makes all the effort of creating stitched images worthwhile. "I still think it's magic when you assemble all the images you're going to use, click the button to stitch and they come together on the screen and finally in the print," he says. "That still gives me a kick, after all the years I've been shooting landscapes."
