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.

CC 1420 LECTURE 6: POLAROID TROUBLE SHOOTING – UNDER/OVER-EXPOSED IMAGE

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.

To use 600 film in a default ISO100 camera(e.g. SX-70 Model 1, Model 2, Sonar, Alpha)

⇒ Use Flash (half power)/ Turn the exposure wheel all the way to darken (black) / Use ND filter

To Use SX-70 film in default ISO100 camera

⇒ In normal case, you should keep the exposure wheel in the middle position

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.

ECOR 1100 Lecture 3: Understanding exposure value (EV)

instant-university_ECOR1100-lecture-3-understanding-exposure-value-icon

HISTORYinstant-university_yellow-border

instant-university_ECOR1100-lecture-3-understanding-exposure-value-#1

In 1950s, Friedrich Deckel, a German shutter manufacturer, first developed the concept of exposure value (EV). He attempted to simplify choosing among combinations of equivalent camera settings.

 

DEFINITIONinstant-university_yellow-border

Exposure value is defined as the exact amount of light hitting a photographic film or image sensor determined by lens aperture and shutter speed, to product a picture which is correctly exposed – neither too light nor too dark.

 

WHAT IS IT?instant-university_yellow-border

instant-university_ECOR1100-lecture-3-understanding-exposure-value-#2

In photography, EV is a numerical scale that represents a combination of a camera’s shutter speeds (determine the amount of motion blur) and f-numbers (determine the depth of field), such that all combinations that yield the same exposure have the same EV value.

Even though all camera settings giving the same EV, it does not mean that they give the same picture. For instance, if you fasten up the shutter speed, the aperture will become larger automatically for compensation, in turns your image maintain the same EV but with shallower depth of field.

instant-university_ECOR1100-lecture-3-understanding-exposure-value-#3

EV also indicates an interval on the photographic exposure scale, 1 EV equals to a standard power of 2 exposure steps, that is, an increment of one step on the EV scale indicates a one step (also called as a stop) increase in exposure, and vice versa.

 

WHEN?instant-university_yellow-border

instant-university_ECOR1100-lecture-3-understanding-exposure-value-#4

If you think your image is quite dark, you can increase the EV. Conversely, if the image is too bright, you can simply decrease the EV.

 

WHICH CAMERA?instant-university_yellow-border

In fact, many instant cameras provide the exposure controls, like Polaroid cameras and MiNT InstantFlex TL70. For example, the EV numbers on Polaroid Land camera Model 180 range from EV 5 to EV 22 while MiNT InstantFlex TL70’s offers EV +/-1.
