MiNT just releases InstantFlex TL70 2.0, their second generation of twin lens instant camera, together with a lens set particularly for TL70. The set includes three ND Filters – ND2, ND4 & ND8, Close-up Lens and Lens Hood. We are pleased to get the set before it has officially released and now we can’t wait to share our experience with you!

 

CLOSE-UP LENSinstant-university_yellow-border

For InstantFlex TL70, the closest shooting distance is 48cm. With applying the Close-up Lens, you can shoot as close as 18cm.

You can take a close-up shot without leaving much background, at the same time, create a shallow depth of view image (by using a big aperture like f/5.6).

 

NEUTRAL DENSITY FILTERS – ND2, ND4, ND8 ✮instant-university_yellow-border

The set includes three ND filters and you may wonder when and which you are required to use them.

The use of ND Filter is to speed up the shutter. Actually, the difference among three ND filters is their intensity to reduce the amount of incoming light entering the camera. ND8 can block the most of light while ND2 block the least.

Fuji mini film has high ISO of 800 while it has high sensitivity to light. Especially when you shoot in outdoor, the sunny/ bright condition will easily lead to an over-exposed photo. Under this circumstance, you have to decide which ND Filter to use in order to obtain a satisfactory image.

When there is a red light shown in viewfinder, it means the shutter speed of camera is now 1/500. The relatively slow shutter speed allows excess amount of light entering the camera, tends to create over-exposure image.

The solution is easy. You can download a smartphone light meter to assist, it helps to achieve a correct exposure. For ISO, set it as 800 (default ISO of Fuji mini film). For aperture, set it the same as which you set on your TL70. Then you will get a number of time automatically.

If the time shows “1/1000”, you need to apply ND2 for shooting. If the time shows “1/2000”, use ND4. If the time shows “1/4000”, use ND8.

 

LENS HOODinstant-university_yellow-border

As long as protecting the lens, the hood can avoid glare and lens flare. So basically you can apply the hood always.

INTRODUCTION
instant-university_yellow-border

Controlling the exposure value (EV) could be really challenging to both beginners and experienced users. Sometimes you may find it difficult to correctly set the exposure wheel. This may result in over/ under-exposed shots.

Impossible film can be mainly classified into two types: high ISO (600) and low ISO (SX-70). Many people are confused about HOW to take a correctly exposed picture.

Reasons of Under/Over-exposed image

instant-university_CC1420-lecture-1-film-storage-#9

Film to use corresponding to indoor/ outdoor?

You are suggested to use flash high ISO film (600) indoor and low ISO film (100) outdoor. If you plan to take pictures in both indoor and outdoor, you should use low ISO film and use flash if necessary.

In a condition of very bright light, even when you use SX-70 film (ISO100 film), it is still possible to result in over-exposed images. There are 2 solutions: adjust the exposure wheel to darken, or use an ND filter and keep the exposure wheel in the middle position.

Most of the SX-70 cameras are programmed as ISO100. In most cases you should use corresponding SX-70 film (ISO100 film) as this will ensure the image is correctly exposed. If you want to use 600 film (approx. 6 times more light sensitive than SX-70 film) in your SX-70 camera, you need to put an ND filter before shooting or you will get over-exposed images.

Temperature differs?

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#8

Photo tends to look pale and with low contrast under cold weather.

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#9When shooting in hot weather, the image tends to look darker and grainy.

instant-university_CC1420-lecture-1-film-storage-#13

Shield after shooting?

instant-university_CC1420-lecture-1-film-storage-#4

Impossible film tends to be sensitive to light. Shield the picture immediately after ejection and avoid exposure under the Sun or bright light. You can use the darkslide (the black cover that ejects immediately after you insert a new film pack) to cover the image. Or even better, use Impossible Frog Tongue to make the shielding easier. Once it is ejected, leave the picture face down for 10 minutes for Impossible B&W films, and 30 minutes for colour films. This will largely increase the successful rate of developing nice pictures.

 

REMARKS

instant-university_yellow-border

  1. Frog Tongue is available for all boxtype/ folding SX-70 and Image/Spectra cameras.

2. The light bulbs on top of SX-70 is the original Polaroid Flash Bar. It is a disposable flash with a 10-times use flashbulb unit. Suitable for SX-70 Camera/ OneStep Rainbow. These flash bars are no longer manufactured and have been gradually replaced by electronic flash.

IU_post1

That’s why MINT created MiNT Flash Bar 2, which is a revolutionary re-usable high quality electronic flash bar device for all Polaroid folding and box-type SX-70 type cameras. It comes with 2 filters for your creativity.

mint_flash_bar2-sx70-camera

3. Lens Set for Polaroid SX-70 Cameras is also available. The set includes Fisheye, Close-up, Blue filter, Yellow filter, and ND filter. You can get as close as 12cm, take selfies with friends, get the nice blue colour of the sky, create higher contrast in B&W photos, and shoot 600 film in SX-70 cameras. It is definitely another must have item besides the flash.

WHY ANNOTATE?
instant-university_yellow-border

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#1

Many Instant Photographers may have the same X-ray concern about carrying undeveloped films when traveling. In this chapter, you will learn what to do and what NOT to do when traveling, without X-ray damaging to your instant films and cameras.

 

HOW?

BRING FILMS AS CARRY-ON LUGGAGE

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#4

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#5Unprocessed film is sensitive to light just as they are waiting to be exposed. Although Impossible Project film has a rather low ISO of 160 for SX-70, and ISO 640 for 600 cameras, X-ray of checked baggage screener may still penetrate and expose the film. Whereas carry-on baggage screener has a much milder X-ray – films under ISO800 such as Fujifilm instax mini film and instax wide film are usually not affected.

So never pack unprocessed film in baggage that will be checked. Or you can politely insist on hand-inspection of the film whenever possible.

PHOTOGRAPHING IN EXTREME TEMPERATURES

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#8Extreme cold guideinstant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#8

When you want to take photos in a freezing cold place (e.g. -10°C to -15°C / 14°F to 5°F and below), you should put the camera inside your bag or  your coat pocket and keep it near your body prior to shooting. Using your body temperature is a good way to ensure that your camera will work well.

Instant film is highly sensitive to temperature. After the camera ejects picture, immediately place it in your pocket or directly onto heat pads. A moderate room temperature of around 25°C / 77°F is optimal for developing camera pictures. Warm the photo with your body temperature is the easiest way. Low temperature will overexpose a photo. It may look bluish, lightened and less contrasted.

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#9Extreme hot guideinstant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#9

Travelling in a place with hot weather (e.g. 35°C to 40°C / 95°F to 104°F and above) is a different situation. Keeping the developing image under shade and keep it cool will help correcting the white balance and prevent reddish and yellowish to a large extent. DO NOT leave the exposing photo under direct sunlight.

Tips:
Hot temperature has a greater effect on B&W film than color. If you wish to get a better result with Polaroid cameras, snap with Impossible Color Film!

Impossible Project film can deliver good results when used within a temperature range of 13°C to 28°C / 55°F to 82°F, while 5°C to 40°C / 41°F to 104°F for Fujifilm instant film.

SHIELDING

Even with Color Protection Film, it is possible to be overexposed under strong sunlight. The first few seconds are extremely crucial for image development. Always shield the film from light when it is ejected.

Can I use a black card, to cover the film with a hand or quickly turn the photo upside down?

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#12
To put a black card at picture exit slot is economical and may help, but it will not work as perfect as the Frog Tongue from Impossible Project.

THE USE OF MANUAL FOCUS

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#14

Some Polaroid cameras such as SX-70 Sonar, use sonar to auto focus. When you are on a coach or railway cabin, visiting in museum or aquarium, as long as there is glass between you and the object, the sonar auto focus will not work because sonar will bounce back when it hits the glass. In order to shoot through glass, simply switch to manual focus and you are good to go!
