Super 8 EKTACHROME 64T motion picture film exposed in old cameras

The automatic exposure system of many Super 8 cameras can read the notches properly and will meter correctly. Any camera that is capable of detecting 6 positions of the film speed notches on the Super 8 cartridge should have no problem. Consult the camera's manual. Use this Super 8 Cartridge Notch Ruler to inspect the mechanism in your own camera.

The automatic exposure system (electric eye) of some Super 8 cameras will not be able to properly expose Kodak Ektachrome 64T film. Some cameras will think that the cartridge is 40 ASA Tungsten stock and will over expose by 2/3 stop, others will think it is 160 ASA and will under expose by 1 and 1/3 stop. You may be able to handle this in several ways:
 * 1) if the camera has manual aperture control, set exposure manually
 * 2) if the camera has +/- exposure compensation, choose 2/3 stop underexposure
 * 3) expose at 40ASA and find a lab that will pull-process, or process it yourself with an E-6 home chemistry kit. Kodak's technical info on pull-processing is here (PDF).
 * 4) adjust the calibration of the exposure meter (as a repair technician would) (not recommended if you plan on shooting other Super-8 film stocks or selling the camera to someone else later on)
 * 5) if the camera has non-reflex (non TTL) auto exposure, use a Neutral Density ND 0.2 filter on the taking lens if the camera reads the cartridge as 40 ASA, or a ND 0.4 filter over the electric eye if it meters 160 ASA
 * 6) if the camera thinks it is 160 ASA, then adjust the exposure override to +1 to underexpose only -1/3 stop
 * 7) make a new cartridge notch so camera thinks it is 160 ASA, and then adjust the exposure override to +1 to underexpose only -1/3 stop
 * 8) enlarge the cartridge notch so camera thinks it is 160 ASA, (if Ektachrome 64 cartridges are recycled, will making the notch bigger render the cartridge less recyclable???) and on a non-TTL exposure meter cover the exposure meter (but not the taking lens) with a ND 0.4 filter. Make the EK 64T notch 0.2 inches larger such that the bottom edge is 0.5 inch from the centre of the cartridge.

Colour correction filter
Kodak states that an 85B filter should be used to colour balance for daylight use. For best colour reproduction you should use an external filter rather than the 85 filter built in to old cameras. Another option is to use a weak warming filter (Wratten 81A) in front of the lens together with the internal Wratten 85 which will lower the colour temperature to the same level as the Wratten 85b alone. For many purposes the built-in filter will be close enough, or colour correction can be done in post processing if you are transferring to video.

 * Leicina Special
 * Lomo 214, 215

Cameras that will not meter correctly, but have manual override
These cameras will not handle auto exposure properly as they will not understand the 64 ASA notch. This is because they have a simple notch-sensing button that only registers 40 ASA T or 160 ASA T, as was common of the last super 8 cameras. You must adjust the aperture to be 2/3 stop less than the camera meter suggests. The technique depends on the type of manual override that is available.

Manual aperture, adjust the aperture to be 2/3 stop less than the camera meter suggests or use an external meter:


 * Agfa Movexoom 4000 Synchrosound
 * Bauer S715XL, S709XL (the manual states the meter sets only 40T/25D and 160T/100D) discuss
 * Beaulieu 1008XL (with +/- density trimmer located inside film compartment)
 * Bell & Howell 1239XL (with +/- 0.8 stop density trimmer inside film compartment)

Adjustable exposure compensation, select -2/3 stop:

 * Chinon Pacific 80SMR
 * GAF 505 XLM (photo)
 * Revue Sound CS60AF

''EE lock. Point the camera at something to make the aperture 2/3 stop less open, then press the EE lock:''


 * Bolex 160
 * Bolex 350 Macro Compact
 * Eumig Mini 5

NOTE: The Bolex 150, 155 and 160 can handle film speeds from 40 to 160. ''EE lock. Point the camera at something to make the aperture 1 and 1/3 stop more open, then press the EE lock:''


 * Canon 514XL, 514XL-S (cameras believe it is 160 ASA Tungsten)

note: Canon 514XLS will overexpose by 1 stop in normal light, by just hitting EE switch-no other changes. Will overexpose 2-3 stops in very bright light, by hitting EE switch- no other changes- per owners manual.

Backlight Switch:
 * Minolta XL-225, XL-440 and XL-660: modify 64T film cartridge by cutting out slot the same as vintage 160 ASA cartridge- sensing pin will then extend into slot, and camera will recognize 64T cart as 160 ASA film- then simply hit "backlight" switch while filming, and hold BL switch in "on" position for entire time while film is rolling-(reason: switch is spring loaded)- this will overexpose by 1-1/2 stops, resulting in exposure rate= approx. 60 (info on 1-1/2 stop overexposure with backlight switch, taken directly from original owners manual) This will work with any camera that has a backlight compensation switch.

Plus one stop compensation, cartridge notch could be broken so camera will read it as a 160 ASA, then adjust the overexposure control switch to +1, so it will actually expose as 80 ASA, underexposing only -1/3 stop:


 * Bolex 350 Macro Compact
 * Agfa Movexoom 6 and 10, also has manual over-ride. Same for 100D- will meter at 80 ASA over-exposing by only +1/3 stop.

Unknown: It's unknown whether these cameras will rate the 64T as 40T or 160T, but they can be adjusted manually to handle the 64T correctly:


 * Chinon 12 SMR Pacific (s. manual, chapter "exposing film at asa's other than 160 and 40")
 * Porst Sound FM 120S (relabled "Chinon 12 SMR Pacific", hence s. manual, chapter "exposing film at asa's other than 160 and 40", too)

Cameras with only manual exposure
These cameras have no built in light meter so of course will handle the new film fine:
 * Bentley BX-720
 * Boots Comet 121
 * Halina Super 8
 * Kodak M2, M12, M22
 * Plus Super 8

Cameras that will not meter correctly
These cameras will not read the cartridge notches correctly and do not have manual exposure control or exposure compensation settings.
 * Agfa Microflex series
 * Bauer Compact 3 XL
 * Bell & Howell T10, T20
 * Canon AF310XL, AF310XL-S
 * Canon Auto Zoom 318M
 * Chinon 313 P XL
 * Elmo Super 311 Low Light
 * Focal XL303 (Only has backlight compensation so cut cart to meter as 160 then use back light control.)
 * GAF XL 415 (In an experiment I simply lowered the lighting until the underexposure warning stayed steady unless pointed nearly directly at a light source. The film came out just fine. Could have used slightly more,(1/3 stop)lighting. Perhaps to the point of the warning going out when pointed near, but not directly at the light source.)
 * Minolta XL-220
 * Minolta Pocket-Z
 * Most of the Kodak Instamatics and XL cameras
 * Porst Reflex ZR422 (Has only ASA 40&160 for Kodachrome K40, Tri-X or other films with the same exposure)
 * Revue Super8 S-100
 * Zeiss Ikon ES8

Cameras with non-TTL automatic exposure
The following cameras cannot meter accurately with the Ektachrome 64T film but have non-reflex (non TTL) external light meters. If the camera reads the notch as 40ASA, use a ND 0.2 neutral density filter on the lens. If it reads the notch as 160ASA, use a ND 0.4 neutral density filter on the electric eye.
 * Kodak XL series
 * Kodak Instamatic M4
 * Eumig Mini 3
 * Eumig Nautica
 * Canon 310XL (photo)
 * Boots 3300 Power Zoom
 * Bell & Howell 670/XL

Cameras that should work...
...correctly with the e64t according to their manuals, but don't according to some tests:
 * Beaulieu 1028 XL 60, 1018 SX 8 and 1008 XL (s. Talk:Super_8_EKTACHROME_64T_motion_picture_film_exposed_in_old_cameras)

Note: These Beaulieu's have a density trimmer inside the film compartment, that can be adjusted +/- one stop to compensate for film speed difference.
