"Starry Camera" App




Super Sensitive Camera Application

This camera app is able to take pictures of a real starry sky. You can take stars of the first magnitude and stars of the second magnitude or less in good condition.

You can also get the pictures processed through more than seventy kinds of image processing filter.
You have only to set your iPhone camera toward a starry sky on a tripod, set the number of exposures, release the shutter and just wait a minute or so to take pictures of the starry sky.

This app can take pictures of a dark starry sky clearly by the technique of multiple exposures that makes exposure time quasi-longer.
Please try with the following multiple exposure parameters for your first use.
Brightness = "normal"
The number of exposures = 50
When the picture you have taken is too dark, increase the number of exposures or change the exposure compensation value to plus (increase). When the picture taken is too bright, reduce the number of exposures or change the exposure compensation value to minus (decrease) When you set the number of exposures to one, you can use camera app as normal camera.

The main functions of this app are as follows.

[Initial setting]

  • (1) Selecting Camera or library Select a rear camera or front camera to use. Or, in addition, if you select a library, you can import photos from camera roll without taking photos.
  • (2) Selecting resolution Select ‘High’, ‘medium’ or ‘low’ resolution. The resolution depends on iPhone model as follows.
    iPhone5, iPhone5c, iPhone5s: 
     (rear camera) 2448x3264, 1080x1920, 360x480   
     (front camera) 960x1280, 720x1280, 360x480
    iPhone4, iPhone4s: 
     (rear) 1936x2592, 720x1280, 380x480 
     (front) 480x640, 480x640, 360x480
    iPhone3GS: 
     (rear) 1536x2048, 480x640, 360x480
    
  • (3) Setting multiple exposure parameters Select ‘bright’, ‘normal’ or ‘dark’ as the brightness of the exposure. You can set the number of multiple exposures from 1 to 100. (If you have selected ‘Bright’, the number of multiple exposures is only from 1 to 20)
  • (4) Setting color temperature When you set color temperature to ‘apply’, you can set it from 1,000 ° K to 12,000 ° K. If you don’t set color temperature to ‘apply’, it uses automatic setting.
  • (5) Setting exposure compensation If you set exposure compensation to “apply”, you can set it from -5.0 to +5.0. (This is an original value and different from the EV value.)
  • (6) Setting dumb shutter If you select silent shutter mode, you can reduce the shutter sound with the volume button. However, if you set it to "mute", the shutter sound will become normal sound. When the number of exposures is 2 or more, the number of shutter sounds is one (for iPhone5).

[Camera function]

You can do camera work according with the parameter set in advance. It allows for pinch in/pinch out digital zooming. In default, the focus is set in the long distance rather than the automatically setting for shooting the stars. If you take pictures of objects at short distance, tap the object on the preview screen and adjust the focus. You need to fix iPhone on a tripod in two or more exposures cases since the shutters are released the exposures number of times. The images might be shifted when you take pictures keeping iPhone in your hand. The shutter also has a 2 -seconds timer for avoiding camera shake when you tap.

[Display list function]

The photos taken in this app is stored in the camera roll and in app itself too and you can see the list of them with the shooting date and time information. You can delete the images by tapping the ‘Select’, and tapping an image you want to delete, then tapping the ‘Trash’ icon.

[Image processing function]

When you tap the image on the list, it displays the list of filters for image processing. It has about 70 filters such as 'Brightness','Contrast','Blur','Sharpening','Sepia','Monochrome','Edge detection','Sketch' and so on. Select a filter from these filters and you can do actual processing to the image on the screen by the selected filter. The image processed can be stored in this app and the camera roll, then you can do another processing subsequently.
This application is compatible with Japanese and English environment.
