A couple of comments:
- Good photographs are made by good photographers. Ansel Adams with a Brownie camera could probably take better pictures than I ever will.
- Kodachrome gives you three things. Wait, 4 things.
- Outstanding color in properly exposed areas.
- Featureless washed out blobs 'o white in overexposed areas.
- Black pits of nothing in underexposed areas.
- Excellent definition
The narrow exposure latitude is a benefit in that it makes the properly exposed portion of a photo (hopefully the important part) really jump off the page, while everything else fades to white or black with little or no definition.
By turning the ISO way down and the contrast way up on today's cameras, you *might* be able to simulate the look of Kodachrome. I say might because I haven't tried.
