Five images stitched together


Recommended Posts

Software, as we all know, is simply wonderful these days.

I had a little time on my hands out of Burntside Lake today,

so I took five overlapping landscape images and merged them in

PhotoStitch, which is Canon software that comes bundled on a CD

with the 30D and later cameras.

It's a VERY simple process using the software, which does almost

all the thinking for you. There sometimes is a little mending and

blending to do along the stitched edges, but usually not much.

Some things to remember when capturing the images are to make

sure your tripod is level so when you swing the camera from side

to side as you progress through the images you're not going

uphill or downhill. You'll also want to shoot in manual mode.

Allowing in-camera metering will deliver slightly different

exposures with some of the frames, making it virtually impossible

to get a good-looking panorama.

You may note a blotchy appearance in portions of the sky, which

is my fault. I did this quickly. For a print I'd take more time

and care to blend and mend.

While a look at the shorelines gives the impression the horizon

is not level, it really is. The islands and shorelines are all

at different depths within the image.

So here I've of course downsized for the Web, but without even

interpolating (adding pixels) in Photoshop CS2, I could print

this to four feet across, and with a bit of interpolation (CS2

and CS3 are great at it), I could easily print this 8 feet across

or more.

Looks great Steve. Well done. I've played with this a little and have the images line up and all, but have had trouble with consistent exposure from one frame to the next. Still some work for me to do.

Mike, with the Canon PhotoStitch software it really IS pretty simple as long as the photographer follows a couple basic procedures outlined above.

I'm assuming the newer Nikon cameras have some similar software version bundled with the NEF converter and such, too.

I like it Steve. I've used the software for a few panos with pretty good success. I just shot a baseball game at the dome and did a 5 shot pano handheld that worked OK, but the roof lines because it is a dome did not match even though the field and action did.

Dan, I've seen other stitched panos of stadiums with the same problem. I expect it's a matter of lens distortion. Even the best SLR lenses have some of it, although if I remember correctly, Canon makes some tilt-shift lenses that are widely used in architectural photography because of their lack of distortion.
