When Photoshop Photomerge goes wrong
When I was up in Los Angeles for National Train Day on May 11, I made a trip to the Capitol Records Building in Hollywood. The last time I was there was in 1978. At that time the building had a huge lobby full of gold records, most notably those from The Beatles and The Beach Boys.
I took many pictures, and twenty years later when digital cameras, scanners, and editing software came along, I scanned them. Sadly, I lost all of them in the Great Hard Drive Crash of August 2005. I was hoping to recapture those pictures.
The building was closed on May 11 (Sunday), and looking in the front entrance glass doors indicated that there no longer is a huge lobby. It’s now like most skyscrapers with an unattended lobby with a directory and elevators. No gold records to be seen anywhere. I satisfied myself with pictures of the building.
Since traffic in Hollywood is heavy, getting into the street to take one picture of a tall building wasn’t feasible. Pictures from the other side of the street were full of utility poles and wires. I decided to pick a spot without junk in the picture and take five or six pictures of sections of the building, my intent being to have Photoshop CS6 do a photomerge when I got back home.
Here is what the photomerge gave me:
I think you will agree with me that the first try at photomerge could be considered photomerge gone wrong.
In looking at the six pictures, I saw that Photomerge was trying to merge two lower pictures that looked rather normal with four upper pictures that had that dastardly tall building retreating perspective the farther up the buildng you got.
My solution was to merge the first two pictures, then merge the next two pictures, then merge the last two pictures. That left me with three pictures. Since the top two were more alike than the bottom two, I merged them, leaving me now with two pictures. A final merge of the two semifinal merges gave me this:
Leads me to believe that the fewer pictures you force Photomerge to use, the better the resulting picture will be. Thus, if you have lots of pictures in your Photomerge, merge them two by two until you arrive at the final two-picture merge. If you started with ten pictures, your flow chart to the final merge would look like this.
