700S is a 35mm tungsten balanced colour negative film that can be C-41 processed in any lab worldwide. For a clean image, shoot at ISO 400. For a grainy image, shoot at ISO 800. Although most people shoot parking lots and gas stations with this type of film, Mr. Negative says 700S really shines when shooting moody portraits during the day, or at night with a flash. 
DX coded for Point & Shoot Cameras.
Manual shooters have full control over creativity being able to shoot at 400 or 800.
