Largest thermal imaging photo sentence

The largest thermal imaging photo consists of 1,051 photos and was achieved by Lelch (China) in Shanghai, China, on 17 October 2024.

The attempt was held at Lelch headquarter in Shanghai as a part of the new product launch. Research department has been working on diaper technique for the past few months to test how well its new flagship product of daytime and nighttime Lelch Buttock Care baby diapers absorb moisture from a baby’s skin. For testing, over 100 baby volunteers from 32 places across the nation as well as some baby manikins took part in it. Thermal technology was used to observe the conditions of diapers worn by babies living in different areas. Colors of varying shades printed on photo papers display the internal humidity and temperature inside diapers. Photos used in the attempt were all from those lab tests.
