À avoir pour régler correctement son appareil photo

Les marques d’appareils photo font des logiciels pour les contrôler. Mais il n’y a pas de contrôle des blancs ou de la lumière dans ces logiciels.
Avoir un iPhone qui est capable de prendre des photos avec son appareil c’est vraiment bien.
Alors ajouter Lux Meter (et Kelvin Meter) est vraiment bien pensé pour compléter ce manque.

Luz incidente

Tengo un android, y compré la app para iOS y no tiene la opción de luz incidente. ¿Cómo lo activo en mi iPhone?

Response from developer

¡Hola! Gracias por descargar Lux Meter en tu iPhone. Lamentablemente, Apple no permite acceder al sensor de luz del iPhone, por lo que la aplicación no puede utilizarlo para realizar mediciones como en otras plataformas. Realmente me gustaría que fuera posible y añadiré compatibilidad de inmediato si Apple permite el acceso a este sensor en el futuro. Lamento mucho esta limitación y gracias por tu comprensión. Puedes escribirme directamente a apps@contechity.com. ¡Gracias de nuevo!

Amazing for beginners

Response from developer
