Pinhole uses a unique method to simulate the long exposure times of a pinhole camera. It does not just simulate the distortion and visual effects, it gradually exposes the scene over time like a real pinhole camera allowing effects not achievable in other "pinhole" apps or regular camera apps.

Unlike a real pinhole camera, all photos are automatically exposed correctly no matter the exposure time. It can optionally simulate the vignetting and edge light bleed typical of pinhole cameras. Exposure time can be set to one of several presets from 15 seconds up to 2 hours, or it can controlled manually for shorter or longer exposures, up to a maximum of about 24 hours.

At any point, choose an "emphasis" image that will dominate the final output—use this to freeze a moving item in the shot (this feature is experimental and the outcome varies widely based on the scene).

Saves directly to your camera roll. Load images to Facebook, Twitter, Flickr, Instagram, Camera+, etc. from there.

Note: the simulation is very memory-intensive, especially on long exposures. For the best stability please close other apps and disable networking to prevent incoming calls and push notifications (put it in "Airplane Mode"). Use "1/4 size" mode which cuts both the horizontal and vertical resolution in half to reduce memory usage dramatically. For best results, plug in your phone before beginning a long exposure.

What's new in V3.2 (July 7, 2020):

• Added file format and (if applicable) quality choices.

What's new in V3.1 (July 6, 2020):

• Added resolution choice, including new "small", 1080p, and 4k support. The 1080p and 4k sizes will expose more slowly and will be more resource-intensive.
• Fixed a few graphical glitches in the UI.
• Minor optimizations and code updates.

What's new in V3.0 (July 1, 2020):

• This is a complete rewrite of the app. The simulation will not be exactly the same as older versions, and it is still evolving so watch for updates. Feedback is welcome!

What's new in V2.3.1:

• iOS11 and latest devices supported
• Fix for iPhone 7/8 Plus crashes
• Minor code refresh

What's new in V2.2:

• New size option: There are now three sizes: "S" (old "1/4 size"), "M" (old standard size), and "L" (new 2x larger). Larger images increase processing time and memory requirements, and could potentially lead to crashes on low-memory devices.
• Improvements in edge effects quality and generation speed.
• EXIF/XMP metadata added to images. Note this data is limited, and some values do not really apply to a pinhole photograph.
• Faster saving and higher-quality image files.
• Support for newer devices and iOS versions.
• Other miscellaneous bug fixes and updates.
