The stereogram uses the side-by-side parallel-view method. The left frame shows the left eye's perspective, and the right frame the right eye's perspective. It might be possible to view this image without a viewing device by diverging your eyes to visually combine the frames, or a stereoscope may be used.

• These photographs are part of a collection of Diapositive film (also known as slide film) which were taken using Canon EOS cameras from 1994 to 2010, explicitly to capture the 3-D view of the sceneries, landscapes or buildings. The slides were scanned using a Wolverine scanner (at approximately 4000 dpi) and then put together using IrfanView software.
• Where necessary some cropping / fine-rotation has been done for corrections. The left image and right image were taken consecutively (and not simultaneously) - with manual approximate positioning of camera as well as approximate framing of the subject(s). Hence, in some pairs, the lighting/ aperture may be different between left and right image. In others, there could be movement of any movable objects / organisms in the images.
• The images have been placed side-by-side in parallel format using the same IrfanView software. Dust, discoloration by age of slides, damage due to handling, etc., may be found, which have not been touched-up.
• Best when viewed on a smart phone with appropriate aspect ratio, using a Google Cardboard / similar VR device.
• For images with portrait orientation, the black space between the images is intentional, for good viewing experience on such a device.
• As mentioned in previous box, viewing by cross-eye technique without any devices will also yield a good 3-D visualization, but a device is recommended for best experience.
• NOTE: The uploaded images are big in size (4K to 5K pixels wide) and can give more clarity, than the default versions that Wikimedia serves on browsers (800 pixels or 1K pixels wide).
