Impossible Instant Lab Framework

With this framework you can expose images using the Impossible Instant Lab.

This framework only runs on iPhone and iPod touch with iOS 6 and later. To give you the best result, you need to have a device with a Retina display.

Usage

  • Integrate the framework into your project via cocoa pods by adding the following line into you Podfile.

    pod 'InstantLab'
    
  • Import the header.

    #import <InstantLab/InstantLab.h>
  • Present the Instant Lab with your image.

    - (IBAction)expose:(id)sender
    {
        UIImage *image = ...
        [IPInstantLab presentInstantLabWithImage:image];
    }

    If you want, you can skip the first step, where you can crop the image by using the -[IPInstantLab presentInstantLabWithImage:skipCropping:] method and passing YES as the second parameter.

  • Enjoy your pictures!

Components

This section describes the major building blocks of the framework. You only need to deal with this if you want to dive deeper and interact with the individual components yourself. By doing so you're leaving the supported path.

The standard flow of an image through the expose process goes through four steps:

  • Cropping the image
  • Optimizing the image and selecting the correct exposure settings
  • Exposing the image to instant film using the Instant Lab
  • And finally a confirmation that tells the user about the expected development time for his picture

Each of those steps is represented by an own controller class. You may subclass them or call them directly with the appropriate input parameters.

IPImageCropperViewController

This controller represents the cropping of the image. It crops the image to the aspect ratio of the image on the instant picture.

You can initialize an instance using the -initWithImage: method, and passing in an image of your choice.

IPOptimizationViewController

This controller allows the user to apply basic image filters (Hue, Contrast, Gamma) onto the image. It is also the place where the user can choose on which film he wants to expose which effects the timing during the actual exposure process.

The initializer of this class also only takes an image -initWithImage:.

IPExposureViewController

This class does the actual exposure. It implements a state machine which is triggered by rotating the device face down. A diagram of that state machine can be found in its implementation file.

You can initialize that controller by invoking -initWithImage:exposureTime:filmIdentifier:. You already see that besides the image this method also expects an exposureTime (in seconds) and a filmIdentifier. The filmIdentifier is a string which is used to let the user know about the development time that is to be expected for the particular film. Feel free to pass in nil here, or choose one from the InstaLabFilms.plist file.
