Pictrure Style


Versione Italiana

The Picture Style is a patch applied to the image, during or after shooting, to change the color range you want. Can be regarded as a film with characteristics of sharpness, saturation and hue different according to the choice. During shooting, the Picture style, are applicable only to permanently while the RAW format JPG will only be associated, this means that in post-production with the Canon DPP you can choose to leave it applied or change type, whereas in Room Raw will be worth the Picture Style excluded. The best way is to shoot in RAW + JPG in order to have even the raw files for any changes.


EOS digital cameras have the Picture Style pre-loaded but you can also add others, CANON downloaded from the website or obtained by users, what we will see in the next step will be just the ability to create new ones to our pleasure. To create the Picture Style, Canon provides a program called "Picture Style Editor" for free download from the site. Before learning how to use the editor, you have to start from the base, ie to understand how colors are expressed.

The espresso color in the picture is made up of three elements:

- H (Hue) = Tone color corresponds to the color perception

- S (Saturation) = thickness, namely its live or off

- L (Luminosity) = brightness, indicates the amount of light of the color


HSL is a model representation of said "natural", that is, close to the psychological perception of color by the human eye.


All colors registered in the photograph can be arranged somewhere on this bicubic representation as a numeric value (coordinates).

The color is represented by a chromatic circle while the brightness and saturation of two axes (X and Y). The values​​, in decimal term, vary from 0 to 359 for the variable H (expressed in degrees) and from 0 to 100 for the variables S and L (expressed in %).


The colors, however, expressed in computer science are composed of three elements:

R = Red

G = Green

B = Blue


These are the three primary colors for the electronic management, which combined together generates a color tone with possible variations of saturation and brightness. In term decimal ranging from 0 to 255, each is composed of a register of the value of 1 byte (8 bits). Where R, G and B = 0 corresponds to black while with R, G, and B = 255 corresponds to white. Below is shown a combination of value, in both methods, to generate the white.




As you can guess, in RGB mode to lighten a color you have to adjust all the variables, unlike in the method HSL just increase the variable L; therefore the latter method is preferred because of its simplicity and accuracy but still not suitable for a quantitative description of a color, so there are other "natural" methods such as HSI or HSV that will not expand but for those who are interested can follow this link.



Picture Style Editor

Launch the program and load an image from the File> Open Image ...

Supported formats are: CR2, CRW, TIF, TIFF.

In addition to the photo will open a second window, the Tool Palette, which is necessary to change the parameters of the colors. The palette is divided into three parts: Base, Axes six colors and specified colors.



In this initial screen, you can adjust the foundations of images such as sharpness, contrast, saturation and color tone. These are the same parameters that can also be changed from the camera.

Among others, at the bottom, there is the Tone Curve Adjustment, which allows you to adjust the contrast and dynamic range.

Before you make the adjustments you need to set the base Picture Style. From the menu choose the style best suited to the image, the ideal is to create a new style from "true and fair".

Below are some of the settings to be taken as a starting point for types of photos.


For images with portraits                                                    For natural images

- Sharpness low                                                                  - Sharpness to zero

- Saturation slightly high                                                     - Low Saturation

- Contrast to zero                                                               - Contrast low

- Toni colors to zero                                                           - Toni colors to zero


For pictures of landscapes                                                 For monochrome images

- Sharpness high                                                               - Sharpness high

- High saturation of the green and blue                               - Saturation to zero

- Contrast slightly high                                                      - Contrast slightly higher

- Toni colors to zero                                                          - Toni colors to zero




It is recommended not to overdo it with the basic settings as these have a total effect on the image.




In this second screen, you can adjust the HSL or more of a sample colors between red, green, blue, yellow, cyan and magenta.

A useful tool to change the brightness or saturation of a specified range of color. The regulations are applicable in different positions for each color sample.

Also in this case it is advisable not to exaggerate the adjustments, because the range of the selected color contains a large gradient of the same color and are settled all the same way, yielding a final result far from that charge.


The adjustments made by this board tools are applicable to Picture style only if saved. Pf3, a new format that contains more information.




Specific colors is the last board tools. As functionality is similar to the previous one, Axes six colors, with the difference that instead of selecting a range of color here you can select with the eyedropper tool, a color tone specific and detailed. The changes you make, such as brightness and saturation, will be applied to that one color without affecting the other tones of nuance.


Prior to sample the colors you can adjust the tone curve using the diagram on the bottom left. You can add up to 10 points selection.


To select a color, you must activate the "dropper" in the upper left, then can select a specific color from the picture or the color table. The numerical value of the selected color appears in the box at the bottom right in the form of HSL or it can be displayed by selecting it from the drop down menu to RGB or LAB. Conversely, you can select a color without the use of the dropper but directly entering the numeric value in the same box.




In addition to the numeric value in the box above, you will see the sample into two qudretti, the left represents the currently selected color while the right changes. The changes will be effected through the HSL sliders.

You can add up to 100 sample points, all on the same color can be influenced by two or more samples, the overlap is displayed in the color wheel with a gray segment while in the color samples you will see a yellow warning light on the colors influenced , is not to be considered as an error but only an alert for any adjustments applied.



Avoid the superposition of colors is better to use a few points samples but adjusted well.



Finally, save your own Picture Style clicking on the icon of the floppy (located on right hand side). Choose the format for saving,. Pf2 is the old format without the control of six axis color adjustment while. Pf3 is the new format but not managed by any cameras.






Using EOS Utility to load the Picture Style realized. Connect the camera to the PC via USB cable, select "Set camera / remote shooting", the second screen click "Register User Defined style" and finally load the Picture Style a single customizable to each channel of the camera.
