About this app

"Oh no! No more!"
Have you ever had the experience of "I want to know what kind of starry sky photos I can take at this location in this season," "I arrived at the location but couldn't see the stars or constellations I wanted because they were hidden by the mountains," or "I couldn't decide on a good composition with the lens I brought with me?"
Yamanoha can reduce such failure cases by simulating the mountain ridges and starry sky for the location, shooting time, and lens used in advance.
"Infinitely expanding starry sky photography expressions"
Yamanoha accurately depicts the mountain ridges and starry sky as seen from a location based on information such as "date," "hour, minute," "direction," "elevation," and "angle of view of the specified lens." Each setting can be easily changed, so you can efficiently perform any simulation.
Yamanoha also has a star trail calculation function that overlays the diurnal motion of the stars. When you want to create a work in which stars leave trails using the "Live Composite" function on OM SYSTEM cameras or the comparative brightness compositing function of image processing software on your PC, you can check in advance how long you need to shoot to create the trail you envision.

1. Specifying the shooting location
1) Selecting the shooting location
Select the shooting location you want to simulate from the list. 10 locations are registered by default.

2) Adding a shooting location [A subscription is required to use this function]
To add a new shooting location, enter the latitude and longitude, or specify the shooting location from the map.

※ Only available in Japan.

※ This function requires an Internet connection to download topographical data. Communication charges are the responsibility of the customer.

2. Specifying the time
Specify the time you want to simulate. Tap the calendar icon to change the year/month, and tap the D/h/m button to change the day/hour/minute.
You can also tap the time specification button to select the current time/moonset (ridgeline)/moonrise (ridgeline)/sunset (ridgeline)/sunrise (ridgeline)/beginning of twilight at dusk/end of twilight at dawn for that day.

* The dates and times that can be specified are 2020-2030.

3. Specifying the composition

1) Switching between vertical and horizontal composition

You can switch between vertical and horizontal composition by tapping the vertical and horizontal composition switch button.

2) Specifying the azimuth and elevation angle

You can specify the direction and elevation angle by sliding the Yamanoha view up and down. You can also select and specify fixed values for the azimuth and elevation angle by tapping the azimuth icon.

3) Specifying the focal length of the lens and fisheye display [A subscription is required to use this function]

You can specify the focal length of the lens you want to simulate by tapping the wide/telephoto button. Fisheye lenses are also supported.

* Sensor sizes supported are Four Thirds, APS-C and full size.

4. Starry Sky Event Information [Subscription purchase required to use this function]

Monthly information on starry sky events for starry sky photography and useful information for photography unique to starry sky photographer Kitayama Teruyasu.

*Internet connection required for this function. Customers are responsible for communication charges.

5. Other Functions
1) Star Trail Display [Subscription purchase required to use this function.]

To display the star trail, turn it on and tap the h/m button to specify the time.

2) Half Sky/Full Sky Display

Half sky/full sky display and star chart can be displayed. Half sky display shows the starry sky in front of you when you are sitting, and full sky display shows the starry sky directly above you when you are lying down.

3) Bookmarks

You can bookmark the simulated results and call them up at any time.

* Star trail display and half-sky/full-sky display cannot be bookmarked.
* Deleting a shooting location will also delete the related bookmarks.
