SX50 HS Panoramic
Feb 18, 2013

Took my SX50 for a walk with my trusty manfrotto tripod and 135 images and 55 minutes later I had enough images to hopefully create the panoramic I attempted and was unhappy with at the same location a week previously. There are a couple of small errors, one image from 135 is focused on the wrong spot aaargh! Let's see who finds it first.

EXIF   (for those who like to see)    
   Model                   Canon PowerShot SX50 HS
   Date/time               17/02/2013 15:32:43
   Image
   Exposure time           1/200 s
   F-number                f/5.6
   ISO speed ratings       ISO 80
   Exposure bias value     0.00 eV
   Metering mode           Center weighted average
   Focal length            33.805 mm
   Custom Rendered         Normal process
   Exposure mode           Manual exposure
   White balance           Manual white balance

Anyways, I am really pleased with the finished image and have uploaded to one of my sites, please follow the link below if panoramic images interest you.

That is very, very impressive, thank you for sharing!

I tried to find out the unfocused patch and also found one at some one and a half marker size distance from the bottom and some three and a half markers size from the left margin: there are some branches in the foreground that suddenly lose focus; in the background there is a white car parked near a house entrance at the left of the building... I don't know how to point it better

Happy shooting,

Augustin

GREAT shot(s). Even the moving traffic looks really good. What software did you use to do the stitching? Did you start with JPG images? Obviously a pretty high powered computer to handle this large file. Thanks for sharing this terrific image.

Incredible!  This puts Gigapan to shame.

Spectacular work.  I think you should be paid to travel the world and do this everywhere.

I used CS6 and exported the file as zoomify. It is approx 50% of the original size at time of export, the original is 69128x7866 it was approx 26-28 frames across and 5 rows. I used manual exposure as I have been rather disappointed with canon's in-camera stitch function, not least because you get such little control of the final image. I locked the tripod vertically (It took a long time to get the tripod level before starting (this is most important!)). I took the images in live view by just fixing onto something in the right hand side of the image and panning the camera. Hence 26 to 28 images, some rows had more going on so I was able to have smaller laps.

I moved the focus flexizone, especially around the bushes, but the one on the basketball court beat me, I thought I had been careful to focus through the branches each time. I couldn't lock the focus as the distance changed with each shot. I used a remote trigger to cut down on vibration as much as possible, there was a bit of breeze up there so this proved difficult at times.

>>One hint I took from pros which really worked well: At the beginning of row 1 I put 1 finger up in front of the lens and shot a frame of my finger, and another single digit at the end of the pan. At row 2 I used 2 fingers, then 3 fingers and so on. This was amazingly useful back home when I needed to sort the images. <<

I stitched the images row by row rather than just throwing 135 images at photoshop and going to bed. Subsequently, I have discovered there must be a cut off with image size and photoshop, as it would only allow me to save the full sized stitched images in PSB (large document format) or tif, but a tif that is not compatible with any other software I have other than windows photo viewer. A full sized jpg would have been nice, alas.

Great tutorial, Julian. That image took a lot of effort and your workflow comments are very much appreciated.

I considered RAW, but to be honest, the extra time extracting each RAW image would have been excruciating and I was quite happy with Canon's superfine Large JPEG images. The fully stitched image is a whopping 1.4GB I can't afford the disk space to also keep the RAW negatives.

I have some RAWs from the previous week and to be honest I struggled to make them better than Canon's JPEGs.

Julian,

Thank you so much for the detailed description of your process. I have never attempted more than one row panoramas. I don't know if I have the patience to do the processing. I am really impressed with your work. I'm not surprised that you used JPG's. Raw files would have been so huge. Thanks again for the extra details.

Steve
