Photographer Field Tools (Pro) v2.9

Requirements: Android 3.0 and up

Overview: All-in-one solution that is designed to leverage the map to provide the necessary tools for photographers to pre-visualize the scene in combination with the Sun, Moon and stars.



** There is a beta release of this app in progress and we would like more people to try it out. It has a viewfinder feature which allows you to view the Sun, the Moon, the stars and the Milky Way as if they appear in your camera's viewfinder. If you are interested in trying it out, please send an email to [email protected] from your gmail account that is on Google+. We can invite you into a beta user community to access the beta releases. Thanks. **

A major upgrade in the 2.x release. We added some great ephemeris features related to Sun, Moon and major stars which allows you to plan the photo shooting even better!


Ansel Adams dedicates the beginning of his first book "Taos Pueblo" to visualization. He introduced the idea of "previsualization", which involved the photographer imagining what he wanted his final print to look like before he even took the shot. Of course there are many great photos which were taken impromptu. However, for landscape photographers, being able to previsualize the scene before going there will greatly reduce the chance of being caught unprepared and will greatly increase the chance of getting better shots.

Photographers use various tools to help them pre-visualizing the scene. Nowadays, many of those tools are phone apps. This Photographer's Field Tools (or PFT in short) is all-in-one solution that is designed to leverage the map to provide the necessary tools for photographers to pre-visualize the scene in combination with the Sun, Moon and stars. Some questions that you might ask yourself before going out for a photographing trip are:

* Where is the Sun or the Moon at the time and the location?

* When and which azimuth is the Sunset or Sunrise today or on any date at any location around the world?

* Where should I go to get a nice view of the scene?

* How far am I from the scene and at what angle will I look at my subject?

* Do I get a clear view of subject from a certain location where is no mountain blocking the view?

* What lens should I bring in order to capture the whole width or the height of the scene?

* How do I compose the scene considering the subject’s elevation and the sun or moon location?

* Can I get the composition I want using one shot so that both foreground and background are in focus or will I have to take multiple shots and stitch them together because of the depth of field is not large enough?

* How many shots do I need to take to create a panorama and how many angle should each shot cover and how many angle should I rotate the camera between each shot?

* Is tonight a good time for star trail photography? How long can I exposure without being affected the rising moon? Where should I aim at the sky to get the Polaris at the center?

If you are interested in the answers of any questions above, the PFT is the right tool for you. In a simple app, we included Tools feature for you which allow you to find out GPS coordinates, elevation, distance, elevation gain, whether there is a direct view between two locations on the map, focal length (both horizontally and vertically, landscape orientation or portrait orientation), depth of field (DoF), hyperfocal distance and panorama, and all of those are represented to you visually on the map. In addition, the Ephemeris features include the sunrise, sunset, moonrise, moonset time and location, twilights, special hours of the day, position of the Sun and the Moon, Sun/Moon Finder, more than 100 stars (such as Polaris) azimuth and elevation angle, star trail planning and exposure time calculation, timelapse and hyperlapse calculation etc.

And we also promise you that more exciting features are on the way in the next few releases!

v2.9 improved the date/time slider to allow you to tap anywhere else to dismiss it, fixed a bug calculating the end time for star-trail, fixed a bug in timelapse calculator, adjusted the tap and long click behavior in the star-trail
