At what ratios does a rectangle become a panoramic format?
When I set up an "orientation" field in my database, I drew the line
at 2:1. This is not an attempt to define a hard rule; it's just my
interpretation. For my website I set up the panoramas in a separate
browser, and I also implemented a search feature where you can limit
the results to certain aspect ratios. I could probably merge the
browsers now that I've added an automatic layout function, but I like
the idea of making the panoramas "special".
Incidentally, I found it much harder to decide what's considered
"square". I noticed that a horizontal 6x7 shot looks much squarer
than a vertical one. Because of that, I set up different limits as
follows:
Horizontal format is called "square" if its aspect ratio <= 1.25
Vertical format is called "square" if its aspect ratio <= 1.15
Those numbers were derived by measuring Pentax 6x7 and RB67 frame
sizes, and studying which photos in the database would be considered
square vs rectangular. IIRC one of the cameras shot much closer to
"square" than the other (I think it was the RB67).
It all sounds very boring, but sometimes you just have to sit down
and quantify stuff.
