iOS Build a Selfie App with Swift 2 Adding Image Filters Adjusting the Drawable Space

Images being rotated after converting to CIImage. How to fix?

I'm running the app on actual iPhone instead of simulator so I can take pics. The only orientation that works fine when taking a pic is landscape left. If I take a pic with iPhone in any other orientation (landscape right, portrait or upside down) the image is rotated when converted to CIImage and show up rotated in the collection view with effects. I know the problem is in the conversion (UIImage -> CIImage) because the image passed in this function is in always in the correct resolution:

func image(image: UIImage, withFilter filter: CIFilter) -> CIImage

However the resolution changes after the conversion:

let inputImage = image.CIImage ?? CIImage(image: image)!

Any idea on how to solve this? I've tried to change CIImage orientation after create it and also searched for some initializer that takes an orientation as parameter.

Hey Patrick Montalbano in the last video of this course Pasan Premaratne comment about this problem, suggesting a solution that would be crop the images so they will all have the same orientation. Hope it helps!
