Funktioniert einwandfrei

Würde ich mir noch wünschen, dass nach dem Ablauf der Zeit ein akustisches Signal ertönt.

Sehr empfehlenswert!

Kein langes Umrechnen, sondern kurz die vorgegebene Belichtungszeit eingeben und schon erscheint die Zeit mit ND-Filter. Ab 30 Sekunden läuft sogar der Timer. Das ist schon sehr hilfreich. Super App!!!

Super App für ND-Filter

Sehr intuitiv und schönes Design. Dass der Timer erst ab 30sek geht, macht für mich auch Sinn da man an der dslr <30sek einfach einstellen kann.
Vielen Dank an den Urheber
