How to Fine-Tune White Balance Settings on the Rebel t5i
You can tell the Canon Rebel t5i to shift all colors to make them a little more blue, amber, magenta, or green no matter what White Balance setting you use. To access this option, White Balance Correction, follow these steps:
Set the Mode dial to P, Tv, Av, or M exposure mode.
You can take advantage of White Balance Correction only in these modes.
Display Shooting Menu 2 and choose WB Shift/Bkt.
The first two numbers next to the option name indicate the current amount of fine-tuning, or shift, and the second value represents the amount of white balance bracketing enabled. All values are 0, indicating that no fine-tuning or bracketing is enabled.
The screen contains a grid that’s oriented around two main color pairs: green and magenta (represented by the G and M labels) and blue and amber (represented by B and A). The little white square indicates the amount of white balance shift.
Use the cross keys to move the shift indicator marker in the direction of the shift you want to achieve.
You also can tap the scroll arrows located on each side of the grid to move the marker. Either way, the Shift area of the display tells the amount of color bias you’ve selected. For example, the shift is two levels toward amber and two toward magenta.
If you’re familiar with traditional lens filters, you may know that the density of a filter, which determines the degree of color correction it provides, is measured in mireds (pronounced my-reds). The white balance grid is designed around this system: Moving the marker one level is the equivalent of adding a filter with a density of 5 mireds.
Tap Set or press the Set button to apply the change and return to the menu.
After you apply White Balance Correction, a +/– sign appears next to the White Balance symbol in the Shooting Settings display. It’s your reminder that White Balance Shift is being applied. The same symbol appears in the viewfinder, right next to the ISO value.
You can see the exact shift values in Shooting Menu 2 and also in the Camera Settings display. (To go from the Shooting Settings display to the Camera Settings display, press the Info button twice.) For example, the values indicate a shift two steps toward amber (A) and two toward magenta (M).
Your adjustment remains in force for all advanced exposure modes until you change it. And the correction is applied no matter which White Balance setting you choose. Check the monitor or viewfinder before your next shoot; otherwise you may forget to adjust the white balance for the current light.
To cancel White Balance Correction, repeat the steps but move the marker back to the center of the grid in Step 3.
Be sure that both values in the Shift area of the display are set to 0.
As an alternative, you can press the Erase button or tap its onscreen icon, found in the upper-right corner of the screen. However, doing so also cancels White Balance Bracketing.
Many film photography enthusiasts place colored filters on their lenses to either warm or cool their images. Portrait photographers, for example, often add a warming filter to give skin tones a healthy, golden glow. You can mimic the effects of these filters by simply fine-tuning your camera’s White Balance settings as just described.
