filters-filter-accessories Looking For Point Light Information?

Bonjour a tous
J’ai fait l’acquisition de se trépied sans vraiment de grandes attentes et car j’avais besoin pour faire des prises de vu nocturne de laisser mon appareil photo en position pendant des temps trop important pour ne pas bouger, j’ai donc choisi le moins cher de la marque Sunpack.
Premier bon point le prix, quasiment au même prix que mon mini trépied
Deuxième, beaucoup de réglages, même si la précision laisse un peut a désirer (en même temps a 14$…)
Troisième, le poids, assez léger pour les options de réglages.

Bon certes ne vous attendez pas a un trépied ultra stable pouvant supporter un reflex avec un téléobjectif, et se réglant sans accoue. Mais si vous avez un appareil photo de taille moyenne a petite, pour prendre des photos de toute la petite famille en vacance qu’une seule chose….. foncez ;)


Help answer the question about Point Light
Consider two ways that light might hypothetically get from its starting point S to its final point?
Consider two ways that light might hypothetically get from its starting Point Light point S to its final point F by way of a mirror: by reflecting from point A or by reflecting from point B. (L = 40 cm) Since light travels at a fixed speed in air, the path of least time will also be the path of least distance. Show by calculation that the path SBF is shorter than the path SAF. cm (path SBF) cm (path SAF)
