Stair-Stepping Through a Panoramic Photograph

Hi Folks:

I’ve written a couple of posts before on panoramic photography; this one is about an idea, an experiment if you like, that I tried recently.

There’s a back story for this experiment, and that is that in the downtown area here there’s a panoramic mural on the side of a building that’s approximately 60 metres/ 200 feet long.  It’s a nice work, and I wanted to make a photograph of it.  It’s on the side of a building, and that side faces a parking lot.

Now most panoramic photographs have one basic thing in common, which is that the location of the camera doesn’t change.  If one is using a camera/ lens that’s capable of shifting, then those shifts can be used to capture more image area.  Otherwise one rotates the camera to capture each image that is rendered in the panoramic software.  I talked about this more in my Photo of the Month article for March.  I mostly use Autopano Pro for my panoramas and my HDR work; it works well for me for the most part.  I’ve also used Hugin, and more recently I’ve also played a bit with Adobe Photoshop CS5.

Panoramic Photography and Stitching “Errors”

Hi Folks:

In a previous post I rambled on a bit about panoramic photography – basically a system where one combines several images into one using software designed for that purpose.  One can also take several images of the same scene at different exposures and combine them into one HDR image using the same software.  Mostly I use Autopano Pro for stitching, although I’ve also used Hugin, and since I work extensively in Lightroom I’ve been playing a bit with Photoshop CS5‘s HDR Pro and panorama tools as well.  To create a stitched image the software looks for the same points in two or more images and assigns them as ‘control points’.  The combined image is then mapped around those control points.  Usually this works very well, but in my previous post I talked a bit about parallax errors and things like that, and sometimes these images don’t get mapped together perfectly.  This can create situations like this: Continue Reading →

Photo of the Month

Hi Folks:

Well, since yesterday was the last day of the month this post may be considered an ‘April Fool’s’ joke, but the only fool in this case is me.  Besides, yesterday was Wednesday and Marcia’s ‘Poetry Corner‘ post and I didn’t want to compete!  Yeah, like that’ll work.  Oh well… 😉

So.  March has been a busy month, photographically speaking.  I made close to 2000 images this month, and while there are those who will shoot that and more in a day, I come from a world of 36 and even 12-exposure rolls of film so I’m still not used to the scattergun approach when it comes to imaging.  Of those 2000 or so images, many were used as the basis for panoramas, or more specifically stitched images, since not all stitched images are panoramas, nor need be.
