Do you already know 360-degree panoramic photos? If you don’t know, it’s a photo that can be seen up, down, left, right, front, fullback looks like what the photographer saw. Actually, there are many formats for photo 360, one of which I will discuss is the Equirectangular format or the popular 360 ° x 180 ° display photo also with the name full spherical panorama, as well as VR Photo (Virtual Reality Photography). If you have ever seen the street view on Google Earth or Google Maps, like that equirectangular photo. You can benefit from the following things when it comes to 360 photograpghy.
Basically, all types of cameras can be used to make this 360 ° photo, either a mobile camera or digital camera and DSLR. Well, the most common (and easiest) is to use digital cameras and DSLRs. For digital cameras and DSLRs, the larger the sensor, the easier the manufacturing process and the good results.
Again, any lens can be used. It would be nice if the lens used is a small focal length. DSLR kit lenses generally use 18-55 mm. If a DSLR is used in addition to full-frame, then we need to know the 35mm standard, because there is a crop factor. DSLRs with APS-C sensors, for example, the crop factor is 1.6. So when using an 18mm lens, the equivalent focal length is 1.6 x 18 = 28.8mm. So, an 18 mm lens at 60D or 550D, the field of view is equal to a focal length of 29 mm on 5D or 6D.
Other equipment needed is pano head and tripod. Panohead is a device as a camera holder so that when taking 360 ° images there is no parallax. Is that parallax? Parallax is the difference in perspective of the image recorded by the camera because of the changing position of the camera lens pupil. Parallax takes a difficult (or even failed) image to put together. Panohead is quite expensive and rarely sells in Indonesia. I once knew an overseas website that sold the cheapest at $ 100. Don’t worry, you can make it yourself.
