## What is Focal Finder?

Beschreibungen EN/DE:
Focal Finder helps you finding out how different subjects will look with a certain focal length!

It uses the camera of your device to simulate the zoom-factor and will immediately show you how your final shoot will look like.
Never switch lenses again if you don't need to! If you shoot with prime lenses, you can easily find out which one suits best for a certain subject.

You're looking for a new lens for your camera but are not sure which one? Test it with this app to find out if it is suitable for you!

Create presets for focal lengths you always want to see.

You can simulate larger focal lengths than the ones your smartphone/tablet has as well as shorter focal lengths.

Features:
- Simulate different focal lengths (Wide-Angle and Tele)
- Set Aspect-Ratio
- Show Grid
- Freeze image and save camera photos
- Create individual presets of your favourite focal lengths

Limitations:
- Depending on your device, the maximal focal length is limited. The iPhone5 can simulate focal lengths up to 800mm!
- When framing close subjects, the app may not as accurate as when framing far subjects

Keywords: Focal Length Calculator, Focal Length Finder, Focal Length Simulator, DSLR Lenses, Camera Lenses

DEUTSCH:
Focal Finder hilft Ihnen herauszufinden, wie Ihre Motive mit unterschiedlichen Brennweiten wirken!
Fragen wie: 
- ist der Unterschied zwischen Vollformat-Camera oder APC-Camera?
Welches Objektiv muss ich in gewissen Situationen einsetzen?
Wie wirkt sich das Seitenverhältnis zwischen 3:2 oder 4:3 aus?
Nehme ich eine Vollformat-Camera oder APC-Camera?
...
gehören der Vergangenheit an.

Die App nutzt die Geräte-Kamera und simuliert den Zoom-Faktor und zeigt Ihnen sofort, wie Ihr Foto aussehen wird.

Wechseln Sie nie wieder Objektive wenn Ihnen das Motiv im Vorfeld nicht zusagt! Wenn Sie mit Festbrennweiten fotografieren, können Sie vorab einfach herausfinden, welche für das gewünschte Motiv am besten geeignet ist.

Wenn Sie nach einem neuen Objektiv für Ihre Kamera suchen, aber noch nicht wissen welches, können Sie die Brennweite mit der App simulieren lassen und herausfinden, welches am besten geeignet ist.

Erstellen Sie Vorlagen für Brennweiten, die Sie immer angezeigt haben möchten.

Sie können sowohl größere als auch kleinere Brennweiten als die Ihrer Geräte-Kamera simulieren.

Features:
- Verschiedene Brennweiten simulieren
- Seitenverhältnis festlegen
- Raster anzeigen
- Individuelle Vorlagen für verschiedene Brennweiten erstellen

Einschränkungen:
- Abhängig vom Gerät ist die maximale Brennweite beschränkt. Geräte wie das iPhone 5 können Brennweiten von mehr als 800mm simulieren!
- der focalLength Wert ist der Factor der am Devise verbaut ist. (wird normalerweise automatisch erkannt, man kann aber den Wert so anpassen das die Berechnungen ziemlich genau sind)
