Your best bet is internegative film, available from either Kodak or Fuji. If you decide to use it, you will have to balance it. Neither films are designed to be dropped into your camera and exposed. You MUST follow the manufacturer's instructions if you expect to get decent results.(posted 9062 days ago)These films are available (in 35mm format) only in bulk rolls. They have to be refrigerated when not in use. To properly balance them you will need to have access to a densitometer, as well as the proper 11- or 21-step silver step tablet for exposure and filtration determination.
You will also need a method of filtering the light used to expose the film. Electronic flash is a no-go with these films. If you use a photoflood lamp, you will need a selection of CC or CP filters. One option is to use an enlarger colourhead, equipped with dichroic filters.
Your average photofinisher may not get much internegative film to process and print; unless you want to develop and print it yourself, you may have to take it to a professional colour lab.
If this is a bit expensive, then you could try a lower contrast colour negative film, and flash it after exposure. After establishing your main exposure, you would remove the transparancy and give it a second exposure through a 2.0 neutral density filter; some experimentation would be in order here.
