saving a clipped image analysis raster

I have a raster that I clipped to a polygon using the image analysis window (regular raster clip doesn't do what I want) but when I go to save the temporary raster to a hard file I get the same results as using the regular raster clip tool. Is there any way to save the temporary image analysis clipped raster so it appears exactly the same way in a hard raster file?

Using the raster clip tool:

The Clip_management tool does not change raster cell size. If you want to "cut" the cells to match your coastline, you need to use a different tool.

I believe the best tool for this is Extract By Mask, setting the cell environment to a small value, say, 100 meters, though I bet you could set the cell size to a smaller value when exporting from the image analysis layer.

Hope this helps you out!
