why do I get only tree peaks on my histogram?

One regular question about the color balance coach target is: why do I get only tree peaks on my histogram?
as you can see on the left side of the hand-drawn graphics that the target is used facing the camera instead of facing the light. When you do so the difference of the light from one side to the other of each white patch changes until it reaches the amount of the next patch so you have a kind of one ongoing fading patch. As you can see now on the graphic on the second side on the right-hand side you have four peaks when the target is facing the main light remember the object of the color balance coach target is to measure the highlight to be sure that we do not get an over exposure of the light and the only way he to make this sure is to measure the highlight side with the target. So in the center of the drying you see the two side-by-side drawings one representing the target facing the camera and the other one representing the target facing the main light giving the proper exposure.
Enjoy your target and keep you posted with all your question how will answer them personally.

Returning From London, Vancouver, Victoria and Kelowna

The BoothPhoto Fall Tour has been a wonderful success. A two-day workshop in London, Ontario, where 45 photographers had the opportunity to have one day of conference style theory and one day applying what they had learned in six studio set up to facilitate learning. Our partners from Stan C. Reade spared no effort in making this day unforgettable for all.
The ColorBalanceCoach, Unilever Pro Flashes and our wide array of lights and light modifiers were on display during a special collaboration for conferences with Lens and Shutter a retailer in western Canada. I presented three conferences, one in incredible environment of Victoria, one near dramatic downtown Vancouver and another in Kelowna's beautiful green valley, home to some of the best Canadian vineyards (Of course I visited some...).
That's not all! Jean-Francois also presented his own light measurement products at the Salon de la photo de Paris and the PhotoPlus Expo in New York.

FAQ: Do I use the exposure info (F-stop and shutter speed) taken from the grey surface or the exposure info taken from the whole disc including the white and black colors ?

The exposure info that you will have when aiming at the target whole or grey patch, will be used as a starting point to set the final exposure using the 4 patches and representation on the histogram. The 4 peaks pattern on the histogram ill be the confirmation of proper exposure.
Once your histogram is perfect, be sure to be on manual mode and do not change the F-stop and shutter speed.

FAQ When I take the picture of the grey surface, should I leave my WB settings to AWB to take the picture for use in setting custom WB ?

For Canon, Nikon and other brands, it does not make any difference the mode that you are in when you take the image you will use for setting the white balance. As a second step the camera will white balance the surface or the image that you have chosen to perform the custon WB.
The FAQ are fuelled by user's questions.

FAQ: My camera has trouble focusing on the grey surface to get a picture for setting the WB. Would an out-of-focus picture acceptable ?

Many cameras have that limitation of focussing before exposure. When you walk in to fill the screen with the target, it may be impossible to focus. There is no problem as long as you are not casting a shadow on the target. So sharp or out of focus target will be as usefull to set your exposure.
These FAQ are fuelled by the user's questions.

How the ColorBalanceCoach target deals with the back light

This fashion image shot in Paris at The "Astre studio" (map) represented a challenge in the calculation of the light. I wanted the light hitting the front of the model only, using as background the graphical shapes of the architecture. The Camera was set on manual exposure and white balance. The disc was placed so it did not get any direct light from the outside. I took the reading of the white balance on the grey target of the ColorBalanceCoach target set it as the working white balance. Then I made the setting for exposure by shooting the 4 patches until the signature histogram of the CBC was obtained and used this setting as my exposure and did the shoot. To make sure I would blur the background, I used a large aperture (this is the smallest number on the setting of the aperture) here it is f/2.8. Not a single shot was missed.

Sand and snow, same exposure problem

In a backlit beach image like the one beside the camera sees all the light tones of the sky and the sand and underexposes the whole image. By reading from a grey card like the reference8, you can always be sure of the exposure and bring back great souvenir images, without spending too much time setting the image and even greater, spending zero time correcting the image in Photoshop.

The ColorBalanceCoach, performs in extreme conditions

In a snow storm there is a natural tendency to set everything on auto and rely on the work of the camera, As you can see in the first image the density and Color balance of the image is off. The image is too dark and reddish due to the cloudy conditions and the grey tone is just normal according to your camera meter. The built in meeter tries to put everything 18% GREY.
By using the ColorBalanceCoach disc as a target you can perform a densiry reading on the gry and also a custon color balance on the same grey material and then confirm your setting by looking at the histogram as you can learm on the site.
The same principle would apply on sand or beach.

In my studio I already have a studio strobe as a second light I want to use a quartz lamp?

Some steps are essential
1- decide which lamp will be the main lamp
2- do not mix different light type on your main subject
3- use your second lamp for a support effect

For example if you use the flash to light your subject you will do an exposure test and a white balance adjustment on the main subject ( using the ColorBalanceCoach), if you need to fill the shadows you may use a reflector, that will not change your color balancing and will not overpower your flash. Then turn on the quartz light and make sure the beam does not spill on the subject face or front.
If the 2 light mix on the subject it will be impossible to make a neutral white balance and your shadows will be contaminated with inproper hues.
So let’s use the quartz to light the background, even if in your view finder you see the effect of the quartz, it may not register yet in the picture. The setting you use for the flash exposure are usually based on an exposure speed of 1/125th of a second with an aperture of f/8 or more. At this speed and aperture the hot light will no register (PIC#1), to figure this out, think of how long you need to set exposure for a night cityscape. Try reducing the speed of the camera until you start seeing the effect, this will happen around 1/15th or longer, do not hesitate to reach the 1 second mark. (PIC#2), (NOTE: you may have to shut the flash’s modeling lamp to avoid the yellow modeling lamp to affect on your subject)

Official launch ColorBalanceCoach

Montreal Photographer Turns Inventor
Making Digital Photography Color-Perfect at the First Shot

Montreal, Wednesday, September 27, 2006- This week Montreal Photographer Jean-François O’Kane will introduce in a world premiere, a new colour balancing system for digital photography that he invented and perfected himself at the Photokina international fair in Cologne, Germany. The “ColorBalanceCoach” is a collapsible disk that looks like a photographic reflector. Made to fit in any photographer’s bag, it confirms in a matter of seconds the whiteness of the white, the exposure and the contrast before a single shot is taken.

"I developed the ColorbalanceCoach as the only tool that a photographer needs to keep with him at all times to take color-perfect pictures. As a photographer I pride myself on producing high quality images, but as an artist, I want to concentrate more on the image itself than on the tools and process", explains Jean-Francois O'Kane.

Mr. O’Kane developed the unique “ColorBalanceCoach” as a one-step easy to use tool for photographers. More than two years in the making, this tool was created as the answer to many questions from the hundreds of people he has taught in his lecture series as “TheStudioCoach”.

Why is a colour balance needed?
The color balance, also called white balance, is a technique that ensures that photography captures real colors, and produces an optimal rendering on a computer monitor or final print. Some digital cameras have exposure and color balance settings that can be set on automatic, but unfortunately, automatic does not necessarily mean exact and photos are often discolored.

The “ColorBalanceCoach” is made of 4 distinct regions called patches. The largest is the grey patch, made of chromatically neutral synthetic material, 18% reflective, that will remain stable in density and color for years to come. The black patch reflects only 5% of the light it receives, the white reflective patch will reflect 95% of the light and the dull translucent patch will reflect 85% of the light. The translucent patch is made of 100% colorless white fabric that will allow a shoot through white balancing area as well as a reflected low-light reflected white balance patch.

Canadian and World-wide Distribution
This new tool will be available in Canada as of October 10, 2006 thanks to Booth Photographic that has announced the coverage of the Canadian market through its network of 150 dealers. As well, it has just been confirmed that Aurora will take on the world distribution of a special edition of the ColorBalanceCoach disk.
Note to media:
Mr. O’Kane will be in Germany until October 2, and in Paris from the 2nd to the 5th. He will remain available for interviews by phone. He will be available for interviews in person upon his return.

Un photographe montréalais devient inventeur :
Il conçoit l'équilibrage parfait de la couleur
dès la première pose pour la photographie numérique

Montréal, 25 septembre 2006- Mardi 26 septembre 2006, le photographe montréalais Jean-François O'Kane lancera en première mondiale au salon international Photokina à Cologne, Allemagne, un nouveau système d'équilibrage de la couleur pour la photographie numérique, procédé dont il est l’inventeur. Le ColorBalanceCoach est un disque pliable sem! blable à un réflecteur photographique. Conçu pour s'insérer dans l'étui de transport du photographe, il confirme en quelques secondes la blancheur, l'exposition et le contraste avant même le premier déclic de l'appareil.

« J'ai mis au point le ColorbalanceCoach afin qu’il soit l'unique outil nécessaire pour obtenir un parfait équilibrage de la couleur en tout temps. En tant que photographe, je me fais un point d'honneur de livrer des images de haute qualité, mais en tant qu'artiste, je veux me concentrer davantage sur l'image que sur les outils et procédés », explique Jean-François O'Kane.

M. O'Kane a développé le ColorBalanceCoach pour en faire un outil complet et facile à utiliser. Fruit de plus de deux années de conception, cet outil a été créé pour répondre aux nombreuses questions de centaines d'élèves inscrits à des conférences qu’il dispense par l’entremise TheStudioCoach. !

Pourquoi est-il nécessaire d'équilibrer la couleur ?
L'équilibre des couleurs, ou équilibrage des blancs, est une technique qui permet de capturer les couleurs réelles et de produire un rendu optimal à l'écran ou à l'impression. Quelques appareils numériques sont dotés du réglage automatique de l'exposition et de l'équilibrage des blancs, mais cet automatisme n'est pas toujours synonyme de précision et produit souvent des photos pâles.

Le ColorBalanceCoach est composé de 4 échantillons. Le plus grand échantillon gris est fait de matériel synthétique chromatiquement neutre dont la densité et la couleur demeureront stables au fil des ans ; il réfléchit 18 % de la lumière. L'échantillon noir ne reflète que 5 % de la lumière, l'échantillon blanc en réfléchit 95 % et l'échantillon translucide mat en reflète 85 %.
Ce dernier est fait de tissu 100 % incolore permet aussi de faire une balance de blanc en mesure incidente.

Distribution canadienne et mondiale
Ce nouvel outil sera disponible au Canada à compter du 10 octobre 2006 grâce à Booth Photographic qui couvrira le marché canadien par l'entremise de son réseau de 150 revendeurs. De plus, Aurora vient d'annoncer qu'elle assurera la distribution mondiale d'une édition spéciale du disque ColorBalanceCoach.
Notes aux médias :
· M. O'Kane sera en Allemagne du 26 septembre au 2 octobre 2006, puis à Paris du 2 au 5 octobre. Durant cette période, il sera disponible pour des entrevues téléphoniques. Les entrevues en personne seront accordées dès son retour.

The quality of light

Very often I'm asked by students why the color of the same object may look different in 2 consecutive pictures?
The more obvious reason is the usage of the auto white balance on the camera, but in some occasions, we found the flash used to be defective. If the flash does not send the same amount of light each time, it can do so by changing the intensity or even the voltage to light the flash tube, sending a different light temperature.
Even if you use a ColorBalanceCoach disc to set your aperture, if the flash varies its power from time to time, even the best calibration tool will not allow you to take perfect pictures.

Take a look at the best affordables and reliable flashes on the market: Aurora

Color Balancing or color correcting

Would you rather Color Balance once at picture taking time or color correct all night after a shoot?
Or: Who painted my wall yellow?
The digital era brought with him a whole lot of fun things, unlimited shootings, everlasting roll of film and perfect auto modes. Oups! I'm starting to talk like a salesman. The auto-everything camera is not out yet.
Let do the test: ask your best subject to stand in front of a white wall while wearing a red sweater take a auto-exposure and white balance picture, now change for a green sweater and shoot and try a blue one after. Then look at all 3 pictures side by side on your computer screen.
The red sweater has a “greenish” wall, the green is on a “reddish” wall and the blue on a yellowish wall. Hey? Where is my white wall? The auto mode ate it! Or painted it!
"Color Balance" / "white balance" these 2 expressions are synonymous and can be used indifferently; because if you set your white to be exactly white, then your colors will be on target.
The auto exposure and color balance features in a camera are set and programmed to look for neutrality, the exposure will try to make everything grey, to prove it aim at a white wall with nothing on it , shoot and you get a grey picture; while the auto white balance (or color balance) will look for an equilibrium of color it may be programmed to look for a white wall but if you place in front of it a big red patch it will try to find the balance in your picture and to compensate for an abnormal area of red will try to compensate by adding green, the opposite color.
To fight the wall painting monster you will need a white balancing tool and an exposure control tool. A new product is available:
The solution is the ColorBalanceCoach disc , it will assist you in performing incident or reflected white balance, your exposure and the full calibration of your image by using the displayed histogram. To use it: Set your camera on manual. Set the exposure on the grey patch. Take a picture of the ColorBalanceCoach using the setting you just measured, then check the histogram, you should see 4 separated peaks, not touching neither end. Make a custom white balance on the grey patch or through the translucent white patch, set it as the working white balance . Shoot!

TheStudioCoach's TIPS on white balance:

--2 minutes of your time to do a good white balance at picture taking, will save you hours of color correction afterward

--Learn to look at your histogram, it will tell you the thruth. Your LCD display behind the camera may not be exact.

--Get a color balancing solution that fits your camera bag, you then have no excuse for to taking it along on photo trips.
