Using CIFilter, which image filters I should use for cloud, sunny moon light in iphone camera

Question

I'm new to CIFilters in iOS, I have to implement some image filters in my project like Cloud, Sunny, Moon light, I don't know which filter I should chose for each of this one.

Below link is the apple official site for CIFilters: https://developer.apple.com/library/mac/documentation/graphicsimaging/reference/CoreImageFilterReference/Reference/reference.html#//apple_ref/doc/uid/TP40004346-CH202-TPXREF101

I'll be very thankful to you if you guide me.

Thanks in Advance. Ahmed Jabir

You might try the CISunbeamsGenerator for the sun and the rays on the moon. As for the clouds, you might try creating some outlines for the clouds, then applying a CIGaussianBlur effect to them to make them look puffy.
Hope that helps!
