I think tunnel pictures are very interesting.  I think that because it snowed, it was pretty but in the spring, I would have enjoyed it more.  I used ISO 100 for all of these pictures.

This tunnel is in Patapsco State Park right after we had our recent snow.  There are icicles on the top of the tunnel.  f-stop is 8.0 and the shutter speed is 1/80.

This is another view of the same tunnel.  I love that you can see the snow and icicles in this one.  F-stop is 5.6 and the shutter speed is 1/160.  This one is my favorite.

This picture is taken off of the B & A Trail.  The f-stop is 4.5 and the shutter speed is 1/200.

This picture was inspiring to be because I like the reflection.  The f-stop is 4.0 and the shutter speed is 1/200.

This was taken mid day at Lake Waterford.  The ISO is set at 200, the f-stop is 4.0 and the shutter speed is 1/125.

This was taken at near dusk at Patapsco State Park.  ISO is set at 800, the f-stop is 4.5 and the shutter speed is 1/200.
