App 1: Lightmate Light Meter
How accurate do you think the light meter built in to your 30 or 40 year old camera truly is? Not very. During the daytime in bright conditions, your built in lightmeter is perfectly fine, but once you start taking photos indoors, at dawn or dusk, it becomes less and less reliable. This is where Lightmate comes into it, Your mobile phone has an advanced camera that is designed to shoot in all conditions, no matter how challenging. Light mate uses this camera to give you the exact settings (shutter speed and aperture) you need to use to achieve fantastic photos no matter how dark or bright it is.
Ive used a few different lightmeter apps and they are all very similar. Lightmate is a free app which is why Ive chosen it over other options
App 2 : Viewfinder Preview
This is a simple app but can be a very powerful tool. It does exactly what it says on the tin. You can choose any film format, stock and lens and see an exact preview of how it looks on your mobile phone screen. This means you can see an exact preview of how your composition looks before you take the exposure. It has a few benefits, such as being able to preplan your photos, use it to observe how tones appear before taking your photo and of course, saving wasted shots.
This app is available on the appstore for €4.99
App 3: Reciprocity Timer
If you shoot at night time, Im sure you will have had issues with reciprocity failure. Reciprocity failure is when the relationship between shutter speed and aperture no longer acts proportionally. This often happens at long exposure times when shooting film. This handy little calculator will tell you the exact time you should be metering for when you need to shoot longer exposure times.
