No, I'm not talking about enhancements for the photos your phone takes, but for the apps that enhance your use of your "real" cameras. We do not need another app to add animal ears and noses to our selfies.

I use "The Photgrapher's Ephemeris" to plot positions of the sun and moon at various times of day and locations. Find it invaluable in getting the right location and angle of light for a particular shot. It's only a couple of dollars IIRC, and I wouldn't be without it. There are weather-centric apps for locating areas with potential fog and lightning, but I haven't tried any of them.

"Light Meter" is a Lux scaled incident meter that uses the camera cell for measurements. Helpful in doing studio light ratios and other similar stuff to determine dynamic range in a scene. It matches my old Norwood Director almost perfectly.

"My Light Meter" is an app that can be operated in reflective and incident modes (I haven't bought the incident dome, so I can't speak to its accuracy there). I was genuinely surprised by how closely it matched my Luna Pro on most reflectivity levels, maybe even a little better on dark surfaces.

Finally there's "Shutter Speed", which is a shutter speed measure, especially useful for older film cameras. Like those above, it's very cheap. You can buy a plug in light to connect to your phone for more accuracy at higher shutter speeds, but the basic model graphs a sound recording, which you can use to pick out the points when the shutter opens and closes. I have a bunch of old Compur and Copal shutters I wanted to check, and this has worked very well, especially at slower speeds, where lag most often shows up on a mechanical shutter. I'm slowly working through all of my equipment with it, but so far, I have found it very accurate - comparing very well on a shutter I recently had tested and calibrated. The neat thing is that you can save each camera (or integral shutter lens) after testing any one speed, so you can easily pull up a list that reminds you that 1/500 is 1/3 stop over on your Rolleiflex and your Super Ikonta runs 2/3 stop slow at 1/15, but regains its accuracy below that. For film shooters and old camera lovers, this is wonderful, and reassuring if you're worried about any of your old gear. I plan to get the plug in light at my earliest opportunity, but you have to order it from Germany, in Euros.


What apps do you find useful? I had honestly never thought about it until recently, but I'm sure other Hoggers have some that they use regularly.
