White Balance in Photography
White balance affects photography in somehow. It will elicit better color rendering of your images as it compensates for lighting conditions-it will render white objects as white, while the other colors will be compensated. A photo without the appropriate white balance may take restricted color cast-an example of which is a yellow tint in direct incandescent lighting or bluish tint under fluorescent light.
The Nikon D5100 has a host of white balance settings available for photographers to adapt to the different environments under which they are shooting. Not only should you know what these settings do, but you should also realize how they affect your image to enable you to make your photo captures more realistic.
White Balance Settings at Nikon D5100
There are different types of white balance settings that are present in Nikon D5100 camera, where each is designed to cope with specific lighting situations. These settings will be accessed using the menu of the camera or via the dedicated WB button behind the camera. A more detailed look into each follows:
1. Auto White Balance: AWB
Details: Auto White Balance (AWB) is the default white setting most cameras use, as is with that of Nikon D5100. The camera computes the resultant white balance settings from the identified ambient light condition level inside the shooting area. It analyzes and tries to correct color originally intended to make the image look as natural as possible.
Pros:
Convenient: Designed for hassle-free use without such manual adjustments and is appropriate through a large number of lighting situations.
Flexibility: Works fine in a number of environments, especially in mixed lighting situations.
Consistent Results: AWB won’t always yield the results required, especially in low lighting conditions. The use of AWB may at times, give the result of somewhat unnatural color casts or inaccuracies.
Lower Control: This gives less control over the color balance as compared to the manual settings.
Best of Use: AWB is fairly used in the casual general photograph purposes where you have required a fast adjustment and not worried too much about the color accuracy.
2. Daylight
Description: The daylight white balance setting could be for shooting with natural sunlight. It generally assists with daylight color temperatures of about 5500K.
Advantages:
Color Accuracy: Performs best in generating the merits of true colors and sunlight in an open, direct beam.
Consistency: Excellent for outdoor photography where the photoshoot site lighting condition will always be consistent.
Disadvantages:
Limited Flexibility: Unsuitable indoors or for use in any artificial lighting situations.
Best Use: Use the Daylight setting for outdoor photography during daylight hours to achieve accurate and vibrant colors.
3. Cloudy
Description: The cloudy white balance setting sorts the exposure for cooler color temperature adjustment, as is the case with overcast skies, around 6000K to 6500K.
Advantages:
Warmth: Gives one’s images a little warmth to the cool tones in the atmosphere below a cloudy sky.
Enhanced Colors: May enhance color output in dull or gray lighting situations.
Disadvantages:
Overcompensation: It, however, may produce very warm tones if applied in conditions where it is not needed.
Best Use: Ideal for shooting on overcast days or in environments with diffuse, indirect sunlight.
4. Tungsten
Description: Tungsten balance setting is specially set for indoor light, mostly made by a tungsten bulb, and usually, it gives an output of bright yellow-colored light that is produced at about 3200K.
Benefits:
Color Correction: Effective in correcting the yellow cast of tungsten lighting, thus rendering colors as they should be.
Better Indoor Shots: Perfect for indoor photography under artificial light.
Drawbacks:
Not All Light Sources: It may not be applicable when there are others, such as fluorescent or LED lights.
Appropriate Use: Tungsten white balance is applied to an indoor photograph setting with incandescent lights for true-to-life colors.
5. Fluorescent
Description: “Fluorescent” here is for balance setting in the context of compensatory for the coolness and greenish light casts between 4000K and 5000K produced by fluorescent lighting.
Pros:
Neutralizes the Green Cast: The greenish appearance of fluorescent lighting has been removed.
Improved Color: Adds brightness to all bright fluorescent lighting colors.
Cons:
Different Quality of Light: There are different types of fluorescent light, and so the setting may not be a perfect correction for all types of fluorescents.
Best Use: Indoor type photography under fluorescent light should be more natural in coloring.
6. Flash
Description: Flash white balance is designed for the match-up of the color temperature of an average camera flash, which is around 5500K.
Benefits Significance:
Accuracy with Flash: Which gives accurate representations of colors while applying flash so that the light from the flash doesn’t induce color casts.
Balanced Shooting: With flash and ambient lighter, hold to an equal color balance.
Limitations:
Most likely Unusable Beyond Flash: Not used in areas without flashes or mixed lighting conditions.
Best Use: Use the Flash setting when using an external flash or built-in flash to achieve accurate color reproduction in your photos.
7. Preset Manual (Custom White Balance)
This means: The white balance setting called Preset Manual lets you shoot a reference picture of a neutral gray or white card under the light conditions in which you will be shooting and use this to balance the white just for that environment.
Advantages:
– Accuracy: It gives the most accurate color correction to very specific lighting conditions.
– Flexibility: Adjusts to unique or difficult lighting situations.
Disadvantages:
Setup Required: It involves taking a reference image to manually set the white balance, which can take time.
Best Use: Preset Manual when you require precise color accuracy in complex lighting conditions, or under mixed lighting sources.
How to Set White Balance on the Nikon D5100
Setting the white balance in Nikon D5100 is a very easy operation. Here is a detailed guide for setting up white balance in numbers:
Turn on Your Camera: Ensure that the Nikon D5100 is powered up and set to the shooting mode.
Go to the White Balance Menu: Just press the ‘WB’ button on the back of the camera. Noon, the white balance setting will pop up on the LCD screen.
Select the Desired White Balance Setting: Make use of the multi-selector to scroll through all the available white balance options. Highlight the one that has the most correspondence to your present lighting conditions.
Confirm Your Selection: Finish by pressing the ‘OK’ button. It confirms your choice and exits the menu.
Take Pictures: The white balance adjusted just right, and the only thing left before taking pictures is to view the images and see whether the color is accurate.
Effective Using White Balance Tips
Get to Know Your Lighting: First, analyze the lighting situation of the location in which you shoot before you go ahead and set the white balance. Since every light source has a different color temperature, selecting the best matched white balance setting could greatly increase the accuracy of your colors.
Use Custom White Balance for Precision: For the most accurate color results in cases where there are strange lighting situations or multiple light sources, use the Preset Manual white balance setting. This is especially necessary when dealing with professional work that requires those exact colors.
Shoot in RAW Format: When you shoot in RAW format, you can modify the white balance during postprocessing without losing any image quality and this gives one a lot of room to adjust color problems later.
Look at Your Images: It is good to look at your images using a calibrated monitor or color accurate device, then the result of your white balance adjustments will be better judged.
Experiment and Practice: Do some experimenting with white balance and practice under different lighting conditions. Start to get a feel for how each setting affects your images so that you can make better decisions in future shoots.
Monitor and Adjust: You should, however, constantly monitor the color temperature and change the white balance accordingly. Lighting may change during the course of a shoot, thus becoming proactive in this respect would help in maintaining a consistent direction as far as color accuracy goes.
Problems, Issues and Their Troubleshooting:
1. Wrong Colors with Right White Balance.
Another reason your colors may be wrong, even though you’ve chosen the correct white balance, could be:
Complicated lighting: The scene where you are shooting probably has additional light sources with temperatures and causing colors to mismatch. In this instance, try using the Preset Manual white balance.
Calibration: As your monitor/display is not correctly calibrated, it is likely to influence your perception of the color accuracy.
2. Color Casts, Undesirable
Having got some color casts in your pictures, you should check that the white balance option you used is correct for the lighting source – and maybe consider adding small tweaks to the balance in post-processing when shooting RAW.
3. Trouble with Preset Manual White Balance
In case you do not get the Preset Manual White Balance set properly:
Appropriate Reference: Take a photo of the reference with a neutral gray or white card, making sure the lighting on it is even.
Correct Exposure: Ensure that the reference photo is properly exposed and never too bright or too dark. A well-exposed reference photo will yield more accurate white balance results.
4. Ineffective Auto White Balance
When the Auto White Balance (AWB) is not successful, one can try:
Lighting changes: AWB will not work in conditions of extreme mixed or variable lighting. In these situations, try switching to a preset white balance that matches the main light source.
Manual Adjustment: Manual white-balance settings, taken when AWB fails to create good color cast corrections.
5. Effects of Color Accuracy in Post-Processing.
If you find that the colors of photos after post-processing show discrepancies with reality:
Calibration of the Monitor: Calibration is essential for accurate color reproduction on one’s monitor. You will find it very helpful for perfect adjustments in post-processing.
RAW Files: Use RAW files to modify the white balance in your editing software. More color information is kept in RAW files for correcting white balance issues.
Advanced Tips and Techniques
For those who seek to get advanced in using white balance in the Nikon D5100, here are some of the advanced tips and techniques:
1. Use a Gray Card for Custom White Balance
Here, use the gray card most meticulously to achieve precise custom white balance. You can:
Position Gray Card: Position the gray card in the same lighting condition as your subject.
Get a Reference Image: Position and photograph the gray card, so it fills the frame, and it’s properly exposed.
Set Custom White Balance: On the camera menu, select the Preset Manual option and use the photograph of the gray card for customizing white balance.
2. Create Custom White Balance Presets for Common Lighting Conditions
Consider creating custom white balance presets if you shoot frequently in certain lighting situations. This will save you time and ensure that shooting in similar environments produces consistent results.
3. Experiment with White Balance Filters
White balance filters can be used to change the coloration of the lights that are used. Various colors and densities of filters are available for fine-tuning your color balance. The results can be quite interesting with some experimentation, and combined colors can often be more efficient.
4. Examine Color Balance Checking through a Histogram
The histogram on your camera can provide insight into your exposure and color balance. Ensure that the histogram does not show any clipping (spikes) in the color channels to indicate color balance issues. Adjust one of your white balance settings accordingly for a well-balanced histogram.
5. White Balance Tools in Post-Processing
Many photo editing software, for example, Adobe Lightroom and Photoshop, have advanced white balance correction capabilities. Use these for fine-tuning the white balance and correcting color problems that were possibly incurred during shooting.
