title: IOS8. Photos application bug?
body: <p>When I use filters in standard Photos application in IOS8, I can't get full metadata.
  I try two methods fetch metadata:</p>
  
  <pre><code>[manager requestImageDataForAsset:asset options:options resultHandler:^(NSData *imageData, NSString *dataUTI, UIImageOrientation orientation, NSDictionary *info) {
      CIImage *ciimage = [CIImage imageWithData:imageData];
      NSMutableDictionary *exif = [NSMutableDictionary dictionary];
      [exif addEntriesFromDictionary:ciimage.properties];
  }];
  
  [asset requestContentEditingInputWithOptions:editOptions completionHandler:^(PHContentEditingInput *contentEditingInput, NSDictionary *info) {
      CIImage *cimage = [CIImage imageWithContentsOfURL:contentEditingInput.fullSizeImageURL];
      NSMutableDictionary *exif = [NSMutableDictionary dictionary];
      [exif addEntriesFromDictionary:cimage.properties];
  }];
  </code></pre>
  
  <p>I have not found any mention to the application Photos. I get such a result is always:</p>
  
  <pre><code>{
  ColorModel = RGB;
  DPIHeight = 72;
  DPIWidth = 72;
  Depth = 8;
  Orientation = 1;
  PixelHeight = 2592;
  PixelWidth = 1936;
  "{Exif}" =     {
      ColorSpace = 1;
      PixelXDimension = 1936;
      PixelYDimension = 2592;
  };
  "{JFIF}" =     {
      DensityUnit = 1;
      JFIFVersion =         (
          1,
          0,
          1
      );
      XDensity = 72;
      YDensity = 72;
  };
  "{TIFF}" =     {
      Orientation = 1;
  };
  </code></pre>
  
  <p>Has anyone found a solution how to get the metadata of the images that have been edited in Photos?</p>
