Project Raster - Aerial Visually Changed

Hello,

 

When you use Project Raster should the projection result be drastically brighter than the original?  What are my choices for remedying this situation?

Here is a synopsis of my workflow...

My two attachments to this question illustrate my conundrum.  Aerial1 is the original MrSid while Aerial2 is the result after using Project Raster.  The original coordinate system was local and being projected to Web Mercator Auxiliary Sphere.  I am using ArcGIS Desktop 10.4.1.

The aerial result is being stored within a file geodatabase, the resampling technique was left as Nearest, I did not add an output cell size, and all other defaults were accepted.

I wouldn't mind having Aerial1 be somewhat lighter, say around 10%, but it seems way over the top now.  I realize I can customize the look within ArcMap for a desktop session but the eventual resting place for this aerial will be as a tile layer stored on the cloud for use within ArcGIS Online.  I will be using the Basemap Gallery Widget which requires all aerials be of the same coordinate system to function properly and since the native coordinate system for ArcGIS Online is Web Mercator it seemed the logical conversion choice.

Thank you in advance.

Jeff
