Exposure Difference Work:
I took the average allumination of each sub image, got to know the min and max illumination across all the sub images.  Then varied the illumination of the sub images w.r.t the average illumination.  So the ones with less illumination got an increase in their color properties, and those with more illumination decreased.  Check the extra arguments to the AccumilateBlend funciton.  You might not see a whole lot of difference
in the exposure corrected image but you will see a change if you compare pixel values.  A better idea would be to only consider the right and left sub images when correcting the illumination.


IScissor work:
Added dragon boats to the Deception Pass panorama.
