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. If you have a device with a high-performance camera these days, you might even be able to capture the Milky Way, depending on the conditions. (Conditions include long exposure (e.g., 4 seconds or more) x 10 or more continuous shots, and keeping the ISO as low as possible while still achieving sufficient brightness.) You can also get the pictures processed through dozens or more kinds of image processing filter. To take pictures of the starry sky, you have only to (1)set your iPhone camera toward a starry sky on a tripod, (2)tap the star icon (star1, star2 or star3), (Star1 is recommended.) (3)release the shutter, and just wait a minute or so. Adjust the long exposure parameters using manual exposure depending on the results. For Star 1, select the brightest pixel for each pixel in the continuous shooting image to highlight the brightness of the stars in the dark night sky. Star 2 raises the tone of brightness according to the number of continuous shots and shoots brightly. Star 3 adds brightness to each pixel of the continuous shooting image and shoots very brightly. Even with the same number of exposures, the images are brightly combined in the low to high order of star 1, star 2, star 3. However, please note that the brightness of Star 3 tends to be saturated.
