For several years it has been my opinion that the names on the cameras, be it NIKON, CANON, LEICA, or whatever, may attract curious eyes, particularly those who may wish to borrow one's equipment. Permanently. Thus, I have placed black Gaffer's tape, available from B & H Photo, among others, over all the names and model designations on the camera and lens. The appearance instantly becomes very mundane, almost unattractive. And when asked what one is shooting, you have the chance to say, "Oh, an old Knee-cone" or "An old Nigh-Con." A smaller, but real additional advantage of blacking out the camera is when shooting close up reflective products. The white name can on rare occasion be seen in the subject. I use the Gaffer's tape as it is high quality and does not offset the glue onto the equipment as easily.
And, while talking about stealth, which may be related to the night safety thread, how do we carry the camera? I loop the strap over itself so as to form what is similar to two half hitches which I slip over my wrist. This allows some freedom with the camera, yet it cannot be dropped. The camera moves from horizontal to vertical easily. The fingers fit nicely into the front recess when carrying and the strap keeps it on your wrist.
With all of these things, one does not look so much like a tourist.
