Ambient Light Adjustment

When looking at monitors and printed materials, ambient light significantly affects their color appearances.

For this reason, selection of the fluorescent lamp (ambient light) to light the room is very important when performing color management.

Corrected under a warm white lamp Bluish color tone

Points to Remember when Setting the Ambient Light

Consider the following points when selecting fluorescent lamps suitable for viewing photos.

Color Temperature

Color temperature, stated in kelvin (K), is a unit to indicate whether the color tone belongs to warm colors or cool colors. Values around 5000 to 6000 K indicate white; the lower values indicate warm colors, and the higher values indicate cool colors.

Commercially available fluorescent lamps can be broadly classified into five types depending on their color temperature.

Warm White White Cool White Neutral White Daylight
Color Temperature 3000 K 3500 K 4200 K 5000 K 6500 K

Generally, neutral white lamps are recommended for the environment to view photos.

Difference in Appearance by Color Temperature

Neutral White Daylight Warm White
Appropriate color tone Bluish color tone Yellowish color tone

Color Rendering Properties

Color rendering properties, stated in the general color rendering index (CRI Ra), are the unit to indicate the reproducibility of the color tone. The maximum value for Ra is 100; the higher the color rendering properties, the more faithful color tones can be seen.
When performing color management, it is appropriate to use high color rendering type fluorescent lamps (color rendering properties: Ra 90 or higher) or triphosphor fluorescent lamps.

Lighting Brightness

The lighting affects photos whether it is too bright or too dark.
Generally, about 500 lx (lux) is recommended when performing color management.

Ambient Light Recommended by Canon


Print Studio Pro has a function to print with color tones adjusted to the lighting of the viewing place (ambient light correction function). See Print Studio Pro Guide for details on the ambient light correction function.


Fluorescent Lamps Used at the Professional's Work Site

At the professional's work site, fluorescent lamps designed for color evaluation with high color rendering properties (D50, color temperature: 5000 K, color rendering index: 90 or higher) are mostly used. If they are not available, the neutral type fluorescent lamps can be substituted for them.

Notes on Ambient Light

Using a Desk Lamp as a Fill Light

If changing the lighting of the whole room to fluorescent lamps designed for color evaluation is not an option, you can see accurate color tones by using a fluorescent desk lamp.
