Using ArcGIS 10.2 for Desktop, I just tested drawing imagery in ArcMap from Add Basemap and then using File | Export Map to create a raster (in my case *.jpg) file, and this worked fine.
you don't need to make an atmospheric correction for the MOD13Q1 product because it was generated by the Maximum Value Composite method,this means that among 16 rasters (16 days) the reflectance value for a pixel is the least contaminated by clouds, but also the one with the maximum value. They provide information on the quality of data VI (vegetations ...
Free high resolution imagery, especially as recent as three months, will be difficult to find. I would suggest checking with local and state GIS offices to see if they are willing to release any aerial imagery they might have recently flown. Commercial companies (DG, Astrium, etc) will not give out their data for free.
As BradHards noted, "pleasing" is subjective. That being said, two methods come to mind: (1) Create a new constant raster, erase the islands (assuming you have a vector layer for their boundaries (if not, create one)), and calculate euclidean distance away from the island shores. ESRI has a white paper outlining this method here, although the general idea ...
If there was a shadow in the raw image, say from a tree or tall building, it will still be in the image after the rectification process. Essentially, parts the photo are being stretched or warped to match the position of visible objects in the photo to known places on a map; this will correct for the pitch, yaw, and roll of the plane during the flight, and ...
