1) What is colour management and how Perfect-Pixs can help you improve colour?

Colour management is simply a system that gets all of your devices to represent colour in a consistent and predictable way. Your need to use a colour management system because your scanner, digital camera, computer monitor and printer all display colors differently. Your color management system makes the 'translation' of color from one device to another happen in a consistent and predicatable manner. Although there are many ways to set up colour management, without real references and a properly adjust computer monitor, colour management can be difficult to impossible to implement.

This is why Perfect-Pixs should be an essential addition to your colour management tool kit! Perfect-Pixs gives you the tools to visually adjust you monitor for brightness, contrast and tone and in conjunction with your monitor gamma adjustment program lets you ensure your monitor is visually optimized for viewing and printing. Perfect-Pixs reference card give your the real world colour and grey references that help analyze, compare and an tweak your colour management system.

2) How is Perfect-Pixs used?

The objective behind Perfect-Pixs is to give photographers an affordable tool set that will let them take better pictures, adjust colors easier using their computer and print colors more consistently. To accomplish these objectives we developed a family of colour rendition, grey tone and custom white balance cards and we provide simple easy to understand instructions in a 30 page manual included with our card kit that explains how to use each of cards.

Taking Better Digital Photographs
The photographer simply takes a photos of the Perfect-Pixs grey tone card using their digital camera's meter. These test shots will tell the photographer which grey tone is really neutral grey for their camera and illustrates to the photographer how their camera captures the grey tone range. Once the correct grey reference has been determined, the photographer can use that reference for future spot metering measurements.

The Perfect-Pixs custom white balance card is used with a digital camera's custom white balance option. Using this card allows the photographer to correctly set the white balance point accurately for the particular light source that they are taking pictures under. Correctly used this should eliminate colour casts in their digial photos that can be caused by an incorrect auto white balance setting.

The Perfect-Pixs Colour Patches card lets the photographer include some know standard colors in their photo or in a test photo taken under the same lighting conditions. This provides the photographer with known colors and a middle grey point that is then used when editing their images later. Including a known colour reference in photo lets the photographer properly process the image for colour later. Without a known reference the photographer is guessing during processing stage.

Adjusting Colours Easier When Editing
In any good colour management system, your monitor is the most critical component. If your monitor is incorrectly adjusted for tone and colour then all bets are off for how your image will look on other monitors and when printed. Perfect-Pixs Card Kit includes detailed instruction on how to use the reference cards and the included image files to let photographer more accurately adjust their monitors for better colour. The cards are used to visually verify monitor setup.

When a photographer includes either the zone card or the colour card in their photo or has taken a test image of the cards, the photographer has a known tone and colour reference to use to set the proper middle grey point using their photoediting software. This technique is explained in the instructions and greatly improves image colour. The cards also provide known colours that can be compared to the image that the photographer can use for hue, tone and brightness adjustments.

Printing colours More Consistently
Perfect-Pixs reference cards when used to take better photos, correctly adjust a monitor and edit images in your photoediting program inevitability leads to better colour in your prints. However, the use of the cards doesn't stop there. The cards provide known tone and colour references that can used to with your printer to help you find the right settings on your printer for printing colour more accurately or to a least determine how you printer handles colour so that you can make the necessary adjustments when editing your images to ensure that you get consistent printmaking results.

Priced Right
Because Perfect-Pixs was originally developed for photography students, the cost of the cards needed to be lower. Perfect-Pixs cards are priced far below what other reference card manufacturers charge.

3) What makes Perfect-Pixs different than the other colour, grey and custom white card products?

The Perfect-Pixs family of colour rendition, grey tone and custom white balance cards were initially created to use as teaching aids and to help our fine art reproduction clients produce their own digital files with known colour references.

The objective was to provide easy to understand and easy to use visual colour references at an affordable price that would be useful to any and all digital photographers.

Unlike 'natural colour' reference cards, Perfect-Pixs colour cards use the primary colours used by digital photographers; RGB: Red, Green, Blue; CMYK: Cyan, Magenta, Yellow and Black. RGB are the colours used by your digital camera, scanner and monitor. CMYK are the colours used by most digital printers.

Perfect-Pixs grey and Zone cards are based on an 11 zone system. The 11 zones provide the necessary references for monitor brightness and contrast adjustment and provides photographic grey points that make Perfect-Pixs ideal for exposure measurement with calibrated and uncalibrated digital camera spot meters.

Perfect-Pixs reference cards are premium reference cards. Every card is printed at high resolution on a 1mm thick precise matte imageboard using archival inks. Properly handled and cared for Perfect-Pixs will last for years withour colour fading or colour shifting.

4) Why is it so important to have my computer monitor properly adjusted for tone and colour?

The ultimate purpose of monitor adjustment is to properly display colours and a full range of tones as accurately as possible on your computer monitor.

If your monitor is NOT properly adjusted, images can look bleached out, too dark or simply be the wrong colour. If you have an unadjusted monitor and edit images using it, then it is very likely that prints of your images will be wrong and that your images will display incorrectly on other computer monitors.

In order to visually adjust your monitor your need a real world reference like Perfect-Pixs to adjust brightness, contrast and something called 'gamma'. Since the display intensity of every pixel from your image (the input) is not displayed on your monitor (the output) exactly the same way, a gamma or an intensity adjustment of each of red, green and blue colours is needed to correct for the differences. Gamma in the simpliest terms means intensity. Gamma correction controls the overall brightness of an image and the ratio of red to green to blue used to display your images. Perfect-Pixs cards are used during your monitor calibration process to help you make your visual adjustments are as accurate as visual adjustments can be.

Without a properly adjusted monitor, all bets are off when it comes to properly displaying or printing your images!

5) How do I use my Perfect-Pixs cards to visually adjust my computer monitor?

Perfect-Pixs cards and support files are used in conjunction with a software program (like Quick Gamma or Adobe Gamma) to visually adjust your monitor.

Your monitor's brightness and contrast controls are adjusted first using the Perfect-Pixs Zone or grey Card then in conjunction with your gamma program the Perfect-Pixs Patches or Graduated cards are used to adjust the individual settings for red, green and blue.

6) Why is there no 18% grey block on Perfect-Pixs cards?

An 18 Percent grey Card is a simple grey-coloured card which is supposed to uniformly reflect 18% of the light which falls upon it.

Grey cards can be used as a reference to set the camera exposure when your light meter and camera is calibrated. Unfortunately with many digital cameras, they are not perfectly calibrated to 18% grey and other variations in camera tolerences can make using an 18% grey target impratical.

Perfect-Pixs Zone and grey cards were designed to provide digital photographers with 11 zones of grey allowing the photographer to use the grey zone that is right for them and their digital camera's 'sweet spot'. With just a couple of test shots, the photographer can identify, the right grey zone for their camera.

7) What is Perfect-Pixs custom white balance card used for?

Digital cameras attempt to find a white point in a scene and adjust all other colours in the scene using this white point as the reference. Sometimes, like all electronic devices, the results are imperfect and images may have a blue, yellow or green colour cast or the colours may simply look off.

This is why many digital cameras have a 'custom white balance' option or feature. This feature allows the photographer to measure a known white object to properly set the anchor for the image's white point.

The Perfect-Pixs Custom White Balance card is a uniform precise matte white target that provides the photographer with a known white reference target for custom white balance measurement.
