This page describes an image 24 Hours of Rainbow
Image caption:
This panoramic view taken with a smartphone of Livorno, Italy, showcases a series of vivid rainbows captured on three different days in December 2021. Rainbows are the result of sunlight being refracted by water droplets suspended in the air, typically after rainfall or during misty conditions. The water droplets act like a prism, breaking up (refracting) the sunlight into the various colours. The different wavelengths of light are refracted by different amounts, which is why we see this layering of colours. The photographer skillfully merged the most remarkable shots taken on different days to highlight the diverse sizes and brilliance of these rainbows. The locations at which the rainbows appear to be centred are different because each rainbow appeared when the Sun was at a different position in the sky. This composite image beautifully captures the transient yet mesmerising allure of rainbows, illustrating their fleeting appearance and gradual dissipation influenced by the shifting atmospheric conditions.

Image caption: Menzione d'onore al concorso di astrofotografia IAU OAE 2023, categoria Immagini fisse con smartphone-dispositivi mobili: 24 ore di arcobaleno, di Fabrizio Guasconi.
Questa vista panoramica di Livorno, Italia, mostra una serie di vividi arcobaleni catturati in tre giorni diversi nel dicembre 2021. Gli arcobaleni sono il risultato della rifrazione della luce solare da parte di goccioline d'acqua sospese nell'aria, tipicamente dopo una pioggia o in condizioni di nebbia. Le gocce d'acqua agiscono come un prisma, scomponendo (rifrangendo) la luce solare nei vari colori. Le diverse lunghezze d'onda della luce vengono rifratte in misura diversa, ed è per questo che vediamo questa stratificazione di colori. Il fotografo ha unito sapientemente gli scatti più significativi realizzati in giorni diversi per evidenziare le diverse dimensioni e la brillantezza di questi arcobaleni. I punti in cui gli arcobaleni appaiono centrati sono diversi perché ogni arcobaleno è apparso quando il Sole si trovava in una posizione diversa nel cielo. Questa immagine composita cattura magnificamente il fascino transitorio ma ipnotico degli arcobaleni, illustrandone la fugace apparizione e la graduale dissipazione influenzata dalle mutevoli condizioni atmosferiche. Riceve una menzione d'onore nella categoria Immagini fisse scattate esclusivamente con smartphone/dispositivi mobili.

Image caption: 这幅全景图是在意大利里窝那用智能手机拍摄的，展示了在2021年12月的三个不同日期分别捕捉到的一系列鲜艳彩虹。彩虹是悬浮在空中的水滴折射阳光所形成的，通常在降雨后或雾气弥漫时出现。水滴就像棱镜一样，将阳光分解（折射）成各种颜色。不同波长的光被折射的程度不同，这就是我们看到这样的颜色层次的原因。摄影师巧妙地合并了不同日期拍摄的最引人注目的照片，以突出这些彩虹的不同大小和光彩。由于每道彩虹出现时太阳在天空中的位置不同，因此彩虹的中心位置也不同。这张合成照片完美地捕捉到了彩虹瞬息万变却又令人着迷的魅力，展示了彩虹受大气条件变化的影响而瞬间出现又逐渐消散的过程。
