Workshop Wednesdays Vol.XVI
Workshop Wednesdays vol. XVI
Welcome to Spring! Did you see the double rainbow yesterday? Does the colour of light and refraction blow anyone else’s mind? Have you ever considered how this affects a photograph and how you can manipulate the camera to achieve different results using colour temperature? With a special shoot planned for the Toowoomba Flower Festival later this month, we want to explore colour and how to create beautiful images that celebrate all the colours in the world! Happy Wednesday everyone (my favourite day!)…
“Refraction is the bending of a light or sound wave, or the way the light bends when entering the eye to form an image on the retina.
refraction is a bending of the sun’s rays as they enter raindrops, forming a rainbow.
An example of refraction is a prism.”
“Chromophobia, also known as chromatophobia is a persistent, irrational fear of colors. A severe form of this phobia can hinder daily activities and can make life self-limiting. People with chromophobia may correlate a distressing past event with a colour.”

Photo For Thought
Pillars Of Creation, Nasa, 1995
The Hubble Space Telescope almost didn’t make it. Carried aloft in 1990 aboard the space shuttle Atlantis, it was over-budget, years behind schedule and, when it finally reached orbit, nearsighted, its 8-foot mirror distorted as a result of a manufacturing flaw. It would not be until 1993 that a repair mission would bring Hubble online. Finally, on April 1, 1995, the telescope delivered the goods, capturing an image of the universe so clear and deep that it has come to be known as Pillars of Creation. What Hubble photographed is the Eagle Nebula, a star-forming patch of space 6,500 light-years from Earth in the constellation Serpens Cauda. The great smokestacks are vast clouds of interstellar dust, shaped by the high-energy winds blowing out from nearby stars (the black portion in the top right is from the magnification of one of Hubble’s four cameras). But the science of the pillars has been the lesser part of their significance. Both the oddness and the enormousness of the formation—the pillars are 5 light-years, or 30 trillion miles, long—awed, thrilled and humbled in equal measure. One image achieved what a thousand astronomy symposia never could.
Wiliam Eggleston: The Father of Colour Photography
“YOU CAN TAKE A GOOD PICTURE OF ANYTHING. A BAD ONE, TOO.”
“Until the 1970s, color photography was considered inappropriate for the artwork. Only black and white photographs met the standards of art critics. But then came William Eggleston (born 1939 in Memphis, Tennessee) and showed that color images can have a place in modern art. The colors in Eggleston’s photos are saturated and intense, the characters pose in front of the camera, and traditional ideas about photographic composition are abandoned.
After he had abandoned a college career, William Eggleston made a living as a freelance photographer. Before starting with color photography in the late 1960s, he had studied in detail black and white photography.
When Eggleston had a solo exhibition at the “Museum of Modern Art” (MoMA) in New York in 1976, and became a big star in the art world, he did not get the approval of all critics though. The reason was not only the color in his photos. Although Eggleston is often referred to as the “father of color photography”, his work is not limited only to this.
William Eggleston also introduced completely new topics to photography. For him, it seems that the reason to take a photograph of a particular thing does not play an important role. Everything can be photographed, or in other words: everything deserves to be photographed. For William Eggleston photography itself has no meaning (“There is no particular reason to search for meaning”) – and nothing is excluded from the photographic vision of the artist.”

Light is made up of wavelengths of light, and each wavelength is a particular colour. The colour we see is a result of which wavelengths are reflected back to our eyes.
Visible light is the small part within the electromagnetic spectrum that human eyes are sensitive to and can detect.
Visible light waves consist of different wavelengths. The colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end.
White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light. Light from a torch or the Sun is a good example of this.
Light from a laser is monochromatic, which means it only produces one colour. (Lasers are extremely dangerous and can cause permanent eye damage. Extreme care must be taken to ensure that light from a laser never enters someone’s eyes.)
Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted.
For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum. Red light is the only light that is reflected from the shirt. If only blue light is shone onto a red shirt, the shirt would appear black, because the blue would be absorbed and there would be no red light to be reflected.
White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected. SOURCE
Colour temperature is a measure of a light’s colour. Mastering it will help you keep your shots looking accurate and free from unnatural colour casts.
There are many confusing terms in photography, and “colour temperature” is definitely up there with the best of them. Its name doesn’t really give you much of a clue what it’s all about, and when you hear people talking about “using a Cloudy white balance setting to correct a 7,000K colour temperature” it can be easy to switch off and do your best to ignore it.
For beginners I’d actually recommend doing just that – it’s the sort of thing you can get away with not knowing while you’re learning more basic photographic skills. However, once you’re at a more advanced level, colour temperature can prove to be very useful, and is a lot simpler to get to grips with than you might expect.
WHAT DOES COLOUR TEMPERATURE MEAN?
The technical definition of colour temperature is full of terms like “black-body radiator” and “chromacity space” – in short, it’s very confusing, very boring, and above all leaves you feeling even more baffled than before.
In layman’s terms though, different light sources produce different coloured light. For example, a candle emits a reddish light, while the midday sun’s rays have a blue tint. These different colours can be expressed using a number, and this number is known as the colour temperature.
Colour temperature is measured on the Kelvin scale, which is denoted by the letter “K” or the word “kelvin” after the number. However, this is largely irrelevant – the only part we’re interested in is the number.
HOW IS COLOUR TEMPERATURE USED IN PHOTOGRAPHY?
You’re probably wondering how all this affects you and your images. Well, the human eye is excellent at adjusting to different colour temperatures, which means that to you and me objects appear roughly the same colour whether they’re outside in the sun or indoors under a lightbulb.
Digital cameras aren’t as good at adapting as we are, and as a result they “see” objects as being different colours depending on the lighting. This can lead to our photos having a colour cast – that is, an overall blue or orange tint – which makes the shot appear unnatural and unpleasing.
Thankfully cameras allow you to correct for these colour casts by telling them the colour temperature of your scene. This is done using the white balance setting – simply tell the camera what type of lighting your scene has (daylight, shade, tungsten etc), and it will use an appropriate colour temperature.
For even more accurate control, some cameras allow you to program in an exact colour temperature in kelvin. You can get a precise value by using a colour temperature meter, or by taking a photo of a white object under the same lighting and letting the camera calculate the temperature. Alternatively you can make an educated guess using the chart below.
COLOUR TEMPERATURE CHART
The chart (above) shows rough colour temperature values for a range of different conditions. The bar is coloured to show the hue and strength of any colour casts that might appear in your shot. Feel free to print it out and carry it with you to help you make quick adjustments on location.
Colour temperature can seem a tricky concept to learn, but once you get used to it you’ll find it becomes second nature. It can be an invaluable thing to know, helping you cope with all manner of lighting conditions to produce photos which appear natural and well-balanced without the need for excessive post-processing.”
Our Story of the Week
Meet the Ford Family: Tom, Heidi, Delilah and Oscar. They own a farm in Tenterfield specialising in apples and cherries and are just good, honest, salt of the earth human beings. I had the absolute pleasure of meeting them when Delilah was only a few months old, back in 2013. We recently had the honour of another photo shoot with the whole family, now including little Oscar as well. If you have ever been to the Jan Powers market at the Powerhouse in New Farm, you may recognise Tom’s face, and hopefully you had the opportunity to try the delights from the Tenterfield Apples stall! It’s families like the Fords that makes us wistful for a country escape and a wholesome, healthy lifestyle. I hope that our third photo shoot together can take place on the Tenterfield farm….Rows of produce, fresh country air, maybe in Springtime or Autumn…with the little ones running around – chooks and dogs as well of course! Ahhhhh…. one day I will make this happen! Thank you so much for trusting us with your portraits so far and just being wonderful people to know and photograph. Can’t wait to see you again soon! (And share the photos with you this week!)…
“Tenterfield Apples www.facebook.com/tenterfieldapples Farm fresh apples and cherries from Tenterfield. Tom and Heidi Ford’s property called “Bald Rock” is situated south east of Tenterfield. Their orchard was established 17 years ago and they produce Royal Gala, Fuji, Pink Lady and Granny Smith Apples and Cherries. They sell their fruit locally and at the Brisbane farmers’ markets. The apples are harvested in Autumn, and the cherries in November and December.” SOURCE
Thank you for getting this far! We hope it’s been a worthwhile read for you and we’ll look forward to checking in next week.
Please call or email anytime if we can help.
