Crowd Panos

Photographing Concerts and their Audiences

 

For as long as I can remember, I have always enjoyed showing the audience when photographing concerts. Invariably there is no way to step back far enough to capture the expansive crowd. Nor do I have a wide angle lens that can take it all in. My solution has been to make a panoramic image by stitching together overlapping views. Like this:

Evening Concert – PC Town Center  —  CLICK picture – with luck your browser will show it bigger

Sadly I can no longer link to a viewer that shows panos well, but with luck your browser will do a reasonable job.

The image here was stitched from eight separate exposures. Here are four of them.

Take a closer look at these four. You can see that stitching them faces some interesting obstacles. Yes, The photos show lots of noise. These photos were taken in the evening, night might be a better word. All at f/5.6 and 1/250s with the camera allowed to adjust the sensitivity (auto-ISO). My old camera doesn’t do so well at ISO 5000 to 25600.  On the left end the light evening sky tricked the camera into underexposing the people and I had to boost the shadows – always bad for noise. On the right end the camera reached ISO 25600 and all the noise that comes with that. I do use some noise removal app for these, but that is another story.

In the minute or so that it took to get this set people moved around quite a bit. Some people even walked along in front. That is one huge problem for stitching. Another is more subtle. Look at the lamp post. In one image it is quite bent, straight in the last. That tells you my lens produces a good about of barrel distortion. These problems, and even exposure nonuniformities are easily solved my my stitching program, Microsoft Image Composite Editor, ICE.

On the bottom it says: Camera motion: rotating motion. Stitched 8 of 8 images. Spans 169.3° horizontally, 48.7° vertically. You can see how the program ballooned the images to correct for distortion, moved them up and down for best alignment and found were to cut  from one to the next. Oh, there are stitching artifacts. In a crowd with everybody moving not even the best AI, for that matter nt even old-fashioned human intelligence, could get it perfect. ICE offers a number of different projections as you can see. For this I stayed with the default cylindrical projection.

The four steps at the top describe the major functions, Import, Stitch, Crop, and Export. In the cropping function it even offers to fill the areas around the edges with “context matching fill”. I did not make use of that for this pano.

The final step is to export. Sadly the Deep Zoom and Photosynth options are no longer of use. Time has marched on and Microsoft has given up on those tools. Even ICE is pretty much orphaned, although still available for download from Microsoft. I chose to export a full quality (100%) JPG image. You can see that it is 18098 pixels wide. That makes for a 98.78 megapixel image. I did go back and trimmed top and bottom, see first image above. The file size still came out as 99.6 MB. Yes, I did scale it down for this post.

Here is another pano. This one is made up of just two images. I am using this as the “featured image” so WordPress does not have to choke on the wide panorama.

The Unplanned Pano

Panoramas are fun, even unplanned ones

This old, long “retired”, gasoline station intrigued me. We were driving along in the rural part of Georgia, up in the northern part, when we came upon this sight. We stopped and I took a number of photos. Only when I was doing my post-processing back home did I realize that I had not taken a overall photo that showed the whole place.

Well, that what the “Create” tab in Photo Gallery is for. The first photo showed the building nicely, the third one included the fuel island, there were a number of other views as I walked around the place, and by the tenth photo I had gotten back close to the starting point and showed the pumps, including the ancient one.

Here are the two shots that together cover the whole place.

You can clearly see that I had not taken these photos from the same spot. Making a pano from these would be asking a great deal from Photo Gallery. And indeed it was asking too much. Here is what it could do. Amazing as it is, but the top left of the marque sign just didn’t match.

So on to the nest better tool, in fact the best there is, Microsoft Image Composite Editor. It too had problems, I tried the different planar motion settings and rotating motion. There were still disturbing stitching artifacts. So I did some perspective correction on each image and tried again. That was better.

A fairly good stitch but the building was way too distorted. Some more fiddling and this was more acceptable. There is a bend in the fuel island base, but I thinks it is not too bad.

Now with some cropping we have a pretty good photo of the whole place. It still amazes me what Image Composite Editor can do, even with images that clearly were not taken with stitching in mind.

Stitching Fun

Panoramas with People

There was a time when making a panorama was a tedious task. Taking the pictures had to be done just so and the assembly of different shots into a finished panorama was arduous. Having people in the panorama was difficult and mostly a no-no. Of course, that was a long time ago. Nowadays you just shoot a number of exposures moving the camera some to get overlapping pictures and the rest is just a few clicks away.

My favorite picture handling tool is Photo Gallery. I use it to import and manage my photos and to do the primary touch-ups and enhancements. But Photo Gallery is a powerful tool even though it is “long in tooth”, not having had an update in three years. It has a panorama tool right on the Create bar. You just select the photos to be combined and it does the rest.

I had a group of six shots taken on a busy street with food trucks. There were people all over the road including some children on the sidewalk in front of me. The photos were taken in rapid succession but the kids moved along quite a ways in the few seconds between the frames. I had planned to make a panorama of this scene. I just selected the photos the way they came out of the camera and sent them to Create > Panorama.

Photo Gallery uses the “engine” from the Microsoft Image Composite Editor to make panoramas. It overlaps the photos and makes alignments, warping each frame to achieve its ends. It even adjusts the exposures as necessary. Here is what it looked like before cropping:

LK8_4936-41-S1-1280

With cropping and some enhancing my panorama looked like this:

LK8_4936-41-S3-1280

If you look really hard you will notice the running boy on the sidewalk is also pictured a little farther along. Cute. I checked my originals and indeed the boy appears in all six, but the panorama tool only shows him twice. Here is a portion of that panorama done as “café art”:

Food Truck Alley

Photo Gallery also incorporates a link to ICE, the Microsoft Image Composite Editor (if installed). Now this program has been updated recently and has powerful ways of controlling the image. So I passed the six photos, now a bit enhanced but not cropped, to ICE. It assembled the parts a bit differently. The boy is still duplicated, along with his companion, and another passerby has been cloned. In the default assembly ICE did make a noticeable stitching error but it is minor. Here the uncropped version:

ICE can save the assembled composite to your computer of upload it directly to Photosynth. I did that. If you click on the image above you will be taken to the panorama in Photosynth.

Here are enlargements of the sections with cloned pedestrians:

Note how nice the “clones” fit into the crowd. They look like regular people. You might even miss them on first glance.

There is more fun that can be made out of these six photos, but that is for another time. Here are the six photos, click on them any you can see them in Photosynth. Note: If you are running Windows 10 and using the Edge browser, you probably will not be able to see this display in Photosynth. Switch to Firefox or Opera and the presentation will run. (Hey Microsoft, do you get the message?)

Museum Photography 2

Visit to the Delta Flight Museum

Delta Airlines recently opened the Delta Flight Museum to the public. The museum is located in two historic hangars, now on the Delta Airline corporate campus. A most interesting place to visit. My visit there also provided me with some additional thoughts and tips on museum photography to go along with my earlier article, Museum Photography.

The Delta Flight Museum is housed in two connected maintenance hangars dating from the 1940s. These historic hangars are now located on the Delta corporate campus adjoining the Hartsfield-Jackson Atlanta International Airport. When you visit, be prepared to show ids at the security gate.

Unlike most museum artifact, aircraft are rather large. This makes getting them into pictures difficult unless you have a very wide-angle lens. I stitch photos together. Photo Gallery does a fine job of that. Microsoft Image Composite Editor (ICE) does a superb job. I use both. ICE is especially handy when some perspective correction also needs to be done.

Delta’s first 767 aircraft is now a museum inside the museum 

The largest item inside the museum is a Boing 767 aircraft. LJK13046-P4-2000Inside the rear portion has been converted into an exhibit area with display cases along the sides.

The Spirit of Delta – Boing 767 aircraft purchased for Delta by its employees, retirees, and friends in the financially difficult times in 1982.

A number of items, like luggage carts, have been turned into display cases and there are numerous interactive displays giving information about the artifacts and the history of flight.

LJK13048-P3-1600

The Delta Flight Museum, like other museums, is illuminated for a pleasant experince by visitors not for cameras. The light requires high ISO settings and the techniques of noise reduction described in the earlier article. The high contrast range, illustrated here by the view into the “business end” of an aircraft engine and the cockpit, requires HDR processing. That technique was also covered in the prior post. For the images here I used primarily the “shadows” slider in Photo Gallery and the HDR effect in onOne Perfect Effects 8.

The many historical items take the visitor back to the early days of Delta, indeed to the early days of passenger flight. There are many interesting artifacts like the early “amenity kit”. Yes, indeed, there was a time when smoking was common in airplanes.

When we look at what flying was like some 85 years ago when Delta got started in the passenger business, we smile at how plain and  simple it all was. The equipment was outright crude, and so was the merchandising and the service.

LJK13025-P4-2000

LJK13028-P3-2000

Even I remember those simple days of flying. On my first flight on a DC-3 when we arrived at our destination the pilot hopped out, unlocked the door to the terminal and came back and unloaded the luggage. The Delta Flight Museum has the first Delta DC-3, now beautifully restored.

Of course, I couldn’t resist this opportunity for a “selfie” in the polished metal of the DC-3.

LJK13034-P5-1280

The Delta Flight Museum is still a work in progress. There are several aircraft outside the hangars that have not (yet) been integrated into the museum experience for visitors. Photography is permitted “for personal use”. There is a museum shop, of course. Be sure to pick up a memento there.

A Fall View

Here is something that is hard to do in any other display media: A tall image that you have to scroll to see.

LJK10295 B-P1-PGstitch-4-2000

This is actually a vertical panorama, stitched together from eight separate exposures. Photo Gallery doesn’t mind which way, or in what order you take a group of overlapping shots. It does a fine job of matching together your world.
