I am currently testing creating a mosaic dataset out counties most recent aerial imagery. I have a small mosaic dataset all set up with overviews which displays perfectly in ArcMap. I can zoom through from 500,000 all the way in and can always see the imagery. It has no trouble displaying both the overviews and the source images. When I publish this out as an image service, and drop in it ArcMap, the overviews display fine, but once I zoom past 3,500, (I assume when it switches to the source imagery) all I see is monotone gray or blue (slightly different color for each tile). This sounds like a statistics issue, but I created two identical mosaic datasets, one with statistics calculated on the dataset and one without, served them up and I see no difference. Also if it were statistics, shouldn't ArcMap be doing the same thing? I do have statistics calculated on the source images. Any suggestions or ideas would be greatly appreciated. Thanks.
