i have created some tiffs and pngs by exporting the USA topo maps from ArcMap using export to tiff and export to png.  I set the dpi for 300.  When load the image into arcmap it loses alot of quality in the raster.  when i open the tiff or png in windows photo viewer (default app for my computer) the images look crisp and clear.  any help?? Thanks!
