The panoramic photography is quite diverse and everyone agrees it’s a photo is a wide format. However, different people have different perspectives, for some, it’s a wide field of view, while for others it’s a virtual tour. It is up to you and how do you perceive this type of image.
The ration must be at least 1/2, but the most usual one is 1/3. Due to computer science, panoramic photography is very diverse. It is usually done by assembling the pictures, and it becomes effortless to make all sort of panoramas with this process. So, let’s discuss what format can be suitable for panoramic photography and from what field of view.
Panoramic photography is above all an image that has a wide format. When the ratio between height and length is at least 1/2, then we consider such photo a panoramic one. In this case, the filed doesn’t matter too much, but some people love when it over 120 degrees because it embraces the angle of human vision, which is more than 140 degrees.
This ratio can, of course, be longer, and reach up to 360 degrees. But, the most common format is 1/3, and many famous photographers use this ratio. You can find many photo frames in this format.
The ratio 1/7 is typical for 360 degrees’ panoramic photography and is shoot with a classic 35mm lens. This type of ratio is used as a header for websites.
What field of view?
For some people, the ratio height/width is enough to describe panoramic photography, while for others, this also includes a wide field of view. If we shoot a photo with a lens that features short focal, bellow 20mm, and then assemble pictures, the field of view will be essential.
It all depends on a number of images you are trying to assemble, but also if the field of view embraced by each of them. For instance, three pictures shoot with the 17 mm include more than 150 degrees for a ½ ratio. However, three images taken with a 50 mm only include about 75 degrees.
Another interesting thing to consider, if you make panorama by reframing the photo, then geometric distortions are very different. You should keep in mind that once you reframe the image, it can be distinguished from the same picture realized by assembling. This difference in size limits the final definition of the photography.
In the reframing it will be 1800×5500 px, and by assembling the final file will be 5200×15500 px.
What image definition you should choose?
In film-based photography, when a photographer wants to achieve the best possible quality of the photo, he would work in a medium or big format. He can make panoramas by reframing these photos taken with a wide angle in 24×36 in a format ratio 1/3.
On the other hand, if he wanted not only to shoot panoramic images but also to have a minimum of definition to make high-quality prints, then he will select the dedicated scenic body like XPan. In this case, the picture will not only be less definite, but the gain will appear brighter.
You should choose the ratio based on the panorama you are trying to capture.
