Photography isย time-consuming. There’sย more to it than bringing aย camera and setting it on Automatic Mode before pointing it towards everything you see, as many tend to believe. A photograph, at least a good one, often requiresย some knowledge before it is taken: Where willย the sun be? What shutter speed is ideal? These questions areย often importantย factors to how the image will appear.
Luckily we live in a world where we have huge technological advantages. In fact, there are applications on your smartphone that can answer the questions above for you with only a couple of clicks. Using such applications can save a lot of time both when preparing for a trip and when using the camera. In this short article I’ll give you my two favorite mobile apps for photography.
Disclaimer: I’m not getting paid by any of these companies to promote their apps. These are simply apps I find useful for my workflow.
The Photographer’s Ephemeris – $8.99
The Photographer’s Ephemeris (TPE) helps you plan outdoor photography shoots in natural light, particularly landscape and urban scenes. It’s a map-centric sun and moon calculator; see how the light will fall on the land, day or night, for any location on earth.

During the last few months, I’ve also been exploring a similar application named PhotoPills thatย I can also strongly recommend. In fact, PhotoPills is a little more advanced than TPE and also shows a great deal of information regarding space and astrophotography. If you like photographing stars or the moon, I would recommend PhotoPills instead of TPE.
NDCalcย ย – $0.99 (New Versioin NDCalc 2)
When I was getting into Long Exposure Photography, NDCalc was one of my most used applications. For those who don’t know what Long Exposure Photography is, it’s a technique when using a slow shutter speed.
Instead of manually calculating what exposure time you need when using a Neutral Density filterย NDCalc does itย for you. All you need to do is insertย what would be the correct shutter speedย without a filter and then selectย what filter you use. If the exposure is more than 4 seconds it shows a countdown button thatย sets off an alarm when it’s done.
Even though this is an excellent app that will make your life a little easier,ย I still recommend learningย to calculate exposure times manually since it is important to understand what you are doing.
I’m curious โ What is your favorite photography application? I’m always on the lookout for something new and useful.

I use these apps on the Android cellphone Samsung Galaxy S5 when planning time to shoot. ๐
Great article! I’ve got TPE for Android, could you recommend an equivalent for NDCalc available for Android? ๐ Thanks!
I use Exposure Calculator with my Android Samsung S5. But most of time I start with one minute exposure and adjust according to the histogram…
Hi Bardiel!
I’m happy you enjoyed the article.
I haven’t used a Android in many years, so I don’t know exactly what apps are best for it. However NDCalc is also available for Andriod as far as I know. See this link: https://play.google.com/store/apps/details?id=com.briandorey.ndcalc&hl=no (I don’t know if it is the same creator though.)
