Aujourd’hui, j’ai vu passer cette image sur Facebook. Loin des th\u00e9ories conspirationnistes, je pense qu’il est important de ma\u00eetriser quelques bases de la photographie <\/span>pour la d\u00e9composer et diff\u00e9rencier les deux clich\u00e9s.<\/span><\/p>\n

 <\/p>\n

\"Montage<\/p>\n

La premi\u00e8re image, prise avec un t\u00e9l\u00e9objectif\u00a0(g\u00e9n\u00e9ralement avec des focales \u00e0 partir de\u00a0100mm<\/span>)<\/span>, ne se limite pas \u00e0 un simple \u00ab\u00a0zoom\u00a0\u00bb.<\/span>\u00a0Elle comprime les plans, faisant para\u00eetre les objets sur un m\u00eame plan et la lune exceptionnellement grande.<\/span>\u00a0Si elle est prise avec un capteur plein format\u00a0(24×36<\/span>)<\/span>, la focale utilis\u00e9e \u00e9tait probablement sup\u00e9rieure \u00e0\u00a0180mm\/200mm<\/span>.<\/span><\/p>\n

Les missions Apollo ont utilis\u00e9 des appareils\u00a0Hasselblad<\/span>\u00a0avec des objectifs comme le\u00a0Zeiss<\/span>\u00a0Biogon<\/span>\u00a060mm<\/span>\u00a0f\/5.6<\/span>\u00a0et le\u00a0Zeiss<\/span>\u00a0Planar<\/span>\u00a080mm<\/span>\u00a0f\/2.8<\/span>, adapt\u00e9s aux\u00a0pellicules<\/span>\u00a0and\u00a0capteurs<\/span>\u00a0au moyen format\u00a0(56×56<\/span>)<\/span>.<\/span>\u00a0Ces focales, pas extr\u00eamement longues, offrent une vue allant de large \u00e0 mod\u00e9r\u00e9e.<\/span>\u00a0Lorsqu’utilis\u00e9es pour photographier la Terre depuis la lune, la Terre semble plus petite,\u00a0car l’objectif ne \u00ab\u00a0zoom\u00a0\u00bb pas consid\u00e9rablement<\/span>.<\/span><\/p>\n

La distinction principale entre les objectifs pour capteurs plein format\u00a0(24×36<\/span>)<\/span>\u00a0et moyen format\u00a0(56×56<\/span>)<\/span>\u00a0repose sur la taille du capteur.<\/span>\u00a0Les objectifs pour moyen format couvrent une plus grande surface, offrant un champ de vision plus large \u00e0 focale \u00e9quivalente, compar\u00e9 aux capteurs plein format.<\/span>\u00a0La focale \u00e9quivalente d’un objectif\u00a0Zeiss<\/span>\u00a0Biogon<\/span>\u00a060mm<\/span>\u00a0utilis\u00e9<\/span>\u00a0sur un format moyen\u00a0(56×56<\/span>)<\/span>\u00a0par rapport \u00e0 un capteur plein format\u00a0(24×36<\/span>)<\/span>\u00a0serait d’environ 93 mm.<\/span><\/p>\n

 <\/p>\n

Il est donc peu appropri\u00e9 de comparer directement ces deux photos, vu la diff\u00e9rence des \u00e9quipements utilis\u00e9s.<\/span><\/p>\n

\"L'aiguille<\/p>\n

Ci dessus, photo de la Lune derri\u00e8re l’Aiguille du Midi, prise par ma m\u00e8re avec son Nikon P1000 \u00e0 la focale de 3000mm.
\nLa photo a \u00e9t\u00e9 prise depuis les Bossons, \u00e0 une distance de 4.7km de l’Aiguille.<\/p>\n
