CC 1235 LECTURE 4: Factors affecting the tones of photos

Even when we use the same Polaroid, the outcome may look so different in a sense that the pictures have various tones. Some are yellowish and reddish, while some may have the blue toned.

What to determine the tone of a picture? Is it related to the camera or the film? We list out 4 major factors to clear your mind.

1. Weather/ physical condition

IU-CC-#1(1)On-Chan

Photographer: On Chan / Location: Ethiopia, Africa

Instant film is highly sensitive to temps. When you shoot in a freezing cold place (e.g. -10°C to -15°C/ 14°F to 5°F and below), the photos tend to look bluish, lightened and less contrasted. And the heat does affect the film. Under hot weather of 35°C to 40°C/ 95°F to 104°F and above, the images all turn out with a reddish or yellowish overtone.

IU-CC-#1(3)Ming-Chan

Photographer: Ming Chan / Location: Hokkaido, Japan

The tone of colour varies under different temperatures. In other words, it depends on how cold/warm you are placing the photo for development. For the Impossible’s current generation of films (mid 2016), the full development takes 20-30 minutes. During this period of time, if the temperature is around 10°C to 15°C/ 50°F to 59°F, the image tends to look bluish, whereas if the temperature is above 30°C/ 86°F, the image tends to look reddish.

2. Source of light

IU-CC-#2(1)Eric-Luk

Photographer: Eric Luk / Camera: SLR670-S / Film: Color Film for 600

It is also related to the colour temperature of light source. Sun is actually appearing bluish in hue, but incandescent light bulbs eject light in yellow. Our eyes have the ability to compensate this colour difference but instant films don’t. So we usually find the bluish image outdoor and yellowish toned indoor shots.

IU-CC-#2(2)Eric-Luk

Photographer: Eric Luk / Camera: SLR670-S / Film: Color Film for 600

Instant film is daylight balanced. From sunrise to sunset, dawn to dusk, the amount of sunlight determines the tone of picture, too.

3. Batch of film

IU-CC-#3(1)Simon-Bernabei

Photographer: Simon Bernabel / Film: Color Film for 600

Different batch of film can cause a lot, too. Before mid 2015, Impossible has not come up with the new formula chemical, so the photos were still a little bit reddish and yellowish. Starting from around Apr/ May 2016, Impossible have changed the formula, more chemicals are allowed to spill over. The new films produce more bluish images.

IU-CC-#3(2)Harriet-Browse

Photographer: Harriet Browse / Film: Color Film for 600

4. The application of filters

IU-CC-#4(2)

The use of accessories gives the photo a special tone. For instance, the blue filter will raise the colour temperature, filling blue tones all over the canvas.

IU-CC-#4(3)

Photographer: Ming Chan / Accessories: MiNT Lens Set (blue filter)

Therefore, please noted that the colour tone is nothing to do with the camera. It matters most with the film and the environment you are photographing.

INTRODUCTION
instant-university_yellow-border

In lecture 2, we have discussed about a cleaning method for the Polaroid SX-70 cameras. After opening the film door, it is easy to see if the rollers are clean. But for some other instant cameras like InstantFlex TL70, it may be difficult to check the rollers as they are located inside the camera body. Don’t worry, we have a solution for this. Apart from asking MiNT warranty centre for regular service, you can do it yourself.

 

CIRCUMSTANCESinstant-university_yellow-border

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#11

When is the time to clean the rollers?

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#12

When you found that there are some unwanted white spots or marks shown on the film, this is probably the cleaning time.

instant-university_CC1420-lecture-7-daily-mint-tl70-cleaning-#6

STEPSinstant-university_yellow-border

1. Put double sided tape on one side of the film in order to make this side sticky.

instant-university_CC1420-lecture-7-daily-mint-tl70-cleaning-#1

Noted: We recommend you use the Scotch Permanent Double Sided Tape and don’t stick the tape on double sides of film at one time. If the tape is too thick the film may be hard to be ejected from the camera.

c862b94b0d28e1b3dd1489071f836f45

2. Open the film door and put the film close to the rollers, assist with hand.

instant-university_CC1420-lecture-7-daily-mint-tl70-cleaning-#2

3. Press the film-ejecting button.

4. When the rollers are pressing the film, the tape sticks away the dirt on one rollers.

Noted: As the width of film is shorter than the length of rollers, when you place the film near the ejecting mouth, put it incline to one side first, and the other side next, this can make sure you clean the whole roller.

instant-university_CC1420-lecture-7-daily-mint-tl70-cleaning-#3

5. Repeat step 2 to 4. This time, turn the film over and let the sticky side touch the other roller.

instant-university_CC1420-lecture-7-daily-mint-tl70-cleaning-#4

instant-university_CC1420-lecture-7-daily-mint-tl70-cleaning-#5

6. Try to do the above steps several time until you think it is okay.

Noted: If you think the the tapes aren’t sticky anymore, you should change a new film with new tape to continue.

Nature of instant camera

Image develops within 5 mins after being ejected from the camera.

instant-university_PH1000-lecture-1-camera-go-think-#2

instant-university_PH1000-lecture-1-camera-go-think-#3

Can machines think? This is a long debating question raised by Alan Turing, a British pioneering computer scientist.

instant-university_PH1000-lecture-1-camera-go-think-#4

Alan Turing

Camera is without a doubt one type of machines. From the time we load the camera with film, check settings, set aperture and shutter speed, correctly focus the desired subject, get nice depth of field and composition as we want, to finally clicking the shutter button. The light capturing actions all happen in a split second.

instant-university_PH1000-lecture-1-camera-go-think-#5

Obviously we, humans, are the one who control the process. But have you ever wondered if camera has the ability to think during the image taking process?

If camera could think, in what way would it affect the final images? Would it adjust the settings and create a different picture and style from photographers? Can it be said that some great photographic arts such as Moon and Half Dome from Ansel Adams are actually masterpieces from camera itself?

instant-university_PH1000-lecture-1-camera-go-think-#1

Moon and Half Dome by Ansel Adams (Credits: http://www.ansel-adams.org)

If camera could not think, does it mean humans are the sole controller of the image taking process? Like famous quote from Ansel Adams: ‘you don’t take a photograph, you make it’. Let’s think about this.

CC 1235 Lecture 3: Decoding the Impossible Code on your Impossible film

instant-university_CC1235-lecture-3-decode-the-impossible-code-title

instant-university_CC1235-lecture-3-decode-the-impossible-code-icon

Look at the back of an Impossible film and you will discover a series of numbers at the edge of chemical pouches. What does this 10-digit-code mean?

In a moment you are going to decode these numbers. Are you ready? Here we go!

instant-university_yellow-border

0415443213

You can break down the code into 5 groups, you will know the production date and type of film by reading this code.

instant-university_CC1235-lecture-3-decode-the-impossible-code-#1

1st and 2nd numbers: Production month

3rd and 4th numbers: Production year

5th and 6th numbers: Machine used for the production (for internal records)

7th and 8th numbers: Film type

9th and 10th numbers: Production day

instant-university_yellow-border

Here is the list of various film type codes used as the 7th and 8th numbers:

02: B&W film for SX-70

32: B&W film for 600 and Image / Spectra

70/72: Color film for SX-70 (including Monochrome Cyan SX-70)

80/82: Color film for 600 and Image / Spectra (including Monochrome Magenta and Cyan 600)

instant-university_yellow-border

So “0415443213” means that the film is a B&W film for 600 and Image / Spectra which was produced on 13th April 2015 by machine #44. Isn’t it easy to decode?

Next time when you are contacting the customer service of Impossible, please state the number of the film as it is easy for the team to understand which film you are referring to and its exact production date!

CHEM 1110 Lecture 2: The chemistry of instant film – how it works?

instant-university_CHEM1110-lecture-2-the-chemistry-of-instant-film-title

instant-university_CHEM1110-lecture-2-the-chemistry-of-instant-film-icon

INTRODUCTIONinstant-university_yellow-border

In 2008, Polaroid closed their last factory manufacturing analog instant film. When people thought there was no film for Polaroid cameras anymore, a group of former Polaroid employee was willing to continue the business and save instant film from going outmoded. Yet, besides taking over the last surviving factory, they did not obtain any technology or recipe of producing instant film from Polaroid. They had to invent a brand new analog film by themselves.

instant-university_CHEM1110-lecture-2-the-chemistry-of-instant-film-#1

Stephen Herchen, The Impossible Project’s chemist

“Instant film is the world’s most chemically complex man-made thing. There’s nothing in the modern age which can do what it can do. It is an entire science and an entire art form unto itself.”
– Stephen Herchen, The Impossible Project’s chemist

When the film comes out and you are watching it develop, there are over hundreds of chemical reactions happening. In this lecture, you will learn how an instant film is developed in a chemistry approach. It is, in fact, a really dramatic process happening.

 

COMPOSITIONinstant-university_yellow-border

1. Silver bromide (AgBr) – sensitive to red, green or blue light
instant-university_CHEM1110-lecture-2-the-chemistry-of-instant-film-#2

2. Hydroquinone (C6H4OH2) – decorated dyes cyan, yellow, magenta, dark blue dye or dark room dye – each dye is paired up with a particular silver bromide

3. Potassium thiosulfate (K2O3S2) – developing agent
4. Potassium hydroxide (HKO) – developing dye
instant-university_CHEM1110-lecture-2-the-chemistry-of-instant-film-#4

 

PROCESSinstant-university_yellow-border

1. Light is capture by the camera lens and focus onto the film.

2. In the negative, there have to be something that can reach to that light and that chemical is called silver bromide (AgBr).

3. Moreover, in this negative, there are 3 dyes, each of those dyes is paired up with the particular silver bromide.

4. When the film is releasing, the rollers of camera squeeze the developing fluid inside the film.

5. The blue dye creates a darkroom environment. Those dyes come in contact with the developing fluid, in which they are able to migrate from the negative to the top of the film where they can be seen.

instant-university_CHEM1110-lecture-1-the-impossible-evoltuion-feature-#9

Impossible | PX 70 Color Shade Push! (Credits: The Impossible Project)

PX 70 Push! is much improved experimental version and yet the color is easier to fade out. The relatively high sensitivity of light / temperature features a whole new color system. Unless the images get peeled, otherwise they shift to blue under the ongoing chemical reaction. In a hot environment, the film turns to red or turns to partial green in a cool one.

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

[ Development time ]
Approximately 4-10 minutes

*PX 70 Push has been discontinued.

instant-university_CHEM1110-lecture-1-the-impossible-evoltuion-feature-#10

Impossible | PX 100 Silver Shade UV+ Film (The Impossible Project)

This batch of films are more stabilised in development, plus the sharper images have successfully aroused the interest of Polaroid users. This eliminates the possibility of undeveloped patch, uneven distribution of chemicals and out-of-tone image, having a satisfied result in imaging.

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

[ Development time ]
Approximately 10 minutes for color film &
approximately 3 minutes for black and white film

Impossible | PX 70 Color Protection (Credits: The Impossible Project)

Impossible innovates the color protection formula which enormously improves the opacification process. As claimed by the company, it does not demand for immediate shielding of the photos after shooting, which is a revolutionary product from Impossible.

Users are suggested to use the color protection film indoor or in suburb. At the beginning of development, it is still fine to expose under light and people can directly observe the process without having an overexposed image.

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

[ Development time ]
Around 25-30 minutes for color film

*Films under phase 5 – PX 70 Color Protection, PX 680 Color Protection & PX 680 Gold Color Protection – have been discontinued.

BIOGRAPHYinstant-university_yellow-border

Edwin Land was born in Connecticut, United States in 1909.

In 1929, when Land was still an undergraduate in Harvard University, he created polariser, an optical filter which passes light of specific polarised light and blocks waves of other polarised light, at the age of 20.
instant-university_HIST1010-lecture-1-edwin-land-life-in-an-instant-#3

The technology of polariser has a wide range of applications. It was used in the production of sunglasses, military hardware and color animation.
instant-university_HIST1010-lecture-1-edwin-land-life-in-an-instant-#4

In 1937, the Polaroid Corporation was officially established.

In 1939, Polaroid created color animation for jukeboxes, 3D glasses for movies, and the ability to dim light coming through a window.
instant-university_HIST1010-lecture-1-edwin-land-life-in-an-instant-#5

In 1943, Land’s 3-year-old daughter asked him why she could not see the photo immediately after it was taken. He felt a rush of inspiration.

His answer to this? 4 years later in 1947, Polaroid one-step instant camera, the world’s first instant camera was invented.
instant-university_HIST1010-lecture-1-edwin-land-life-in-an-instant-#6

In late 1948, this never-before-seen camera – called the Polaroid Land Camera – hit stores shelves, made an instant success and took the world by storm. It was available in sepia tones only.
instant-university_HIST1010-lecture-1-edwin-land-life-in-an-instant-#7

In 1950, Polaroid’s first instant camera using black and white film was born. It was popular for both military and civilian photography.

Harvard University awarded Land an honorary doctorate in 1957 for his lifetime of scientific achievement.

Polacolor, the first instant camera using color film was introduced in 1963.
instant-university_HIST1010-lecture-1-edwin-land-life-in-an-instant-#8

Land was a pioneer as a manager of Polaroid. In 1960’s he hired women and minorities for management and research positions ahead of many other firms.

In 1971, Land formulated and introduced Retinex theory – both the eyes and the brain are involved in the processing.

In 1972, Land introduced Polaroid SX-70 – a camera with the picture emerging from the camera automatically. It has become one of the most popular products and increased the company’s revenue by 4 times from 1961 to 1972.
instant-university_HIST1010-lecture-1-edwin-land-life-in-an-instant-#9

A failure of film venture called Polavision was a financial disaster to the company. Land resigned as Chairperson of Polaroid in 1980.

After retiring, Land founded the ‘Rowland Institute for Science’ to go on his research on optics. His lab eventually discovered how color is perceived in the human brain.

In 1991, Edwin Land died in Cambridge, at the age of 81.

SFA 1203 Lecture 2: After effect – Manipulation by Impossible film

instant-university_SFA1203-lecture-2-manipulation-title

instant-university_SFA1203-lecture-2-manipulation-icon

WHAT IS IT?instant-university_yellow-border

Manipulation is an alternative artistic “painterly effect”. You can convert a normal picture into an Impressionism painting or oil painting! It is very creative, isn’t it?

From old films like Polaroid SX-70 Time Zero or 600 to The Impossible Project. You can create an image with unique result through manipulation, before the emulsion dries.

instant-university_SFA1203-lecture-2-manipulation-#1

“Manipulation makes your Impossible PX70 and PX680 like a little impressionist canvas.” – Carmen Palermo (Credits: The Impossible Project & Carmen Palermo)

 

HOW?instant-university_yellow-border

instant-university_SFA1203-lecture-2-manipulation-#2

Manipulation involves taking a blunt object by applying pressure to a still developing Polaroid. The tools used to the process could be a wooden stick or Cold Clip Pen by Impossible. Sharp tool would ruin the emulsion layer so avoid using it.

instant-university_SFA1203-lecture-2-manipulation-#4

Use pressure to create a blending and slight distortion on the chemicals. Remember, the picture can no longer be restored.

instant-university_SFA1203-lecture-2-manipulation-#3

**Drawing on Impossible film is not as easy as the original Polaroid SX70 film. To do so, it is better for you to heat up the image by hairdryer first and draw harder.

YOU MAY ASK…instant-university_yellow-border

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#11How to know when the film is produced or expired?

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#12On the packaging of The Impossible Project film, there is a 4-digit number (MM.YY). And there are two types of dates: one is ‘production date’, the other is the ‘best before date’. If it is ‘production date’, then use it within 1 year since the production date. If it is ‘best before date’, then use it before the stamped dates. It is suggested that the film should be used before the date printed in order to obtain the best photographic result.

In 2016, The Impossible Project will gradually unify the date system. All new packages are going to be stamped with production dates regardless of box types.

instant-university_CC1235-lecture-2-fresh-film-and-expired-film-#5
While you will find only ‘best before date’ on Fujifilm instant film. It is suggested that the film should be used before the date printed.

 

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#11Can I still take pictures with expired films?

instant-university_CC1420-lecture-3-air-traveling-with-instant-films-and-cameras-#12Each instant film has pouches filled with photographic developer. Chemical changes and easily runs dry as film ages, resulting in color shifts, a loss in image contrast or uneven spread of chemical over the film. But still, quite a lot of instant photographers are willing to take risks of using expired films. The reason being is that expired materials can create unexpected yet fun results such as bluish or greenish picture. It’s not the end of the day even if films expire.

instant-university_CC1235-lecture-2-fresh-film-and-expired-film-#4
