Noise reduction is typically not considered a color correction technique. It is used to reduce image noise, which is a grainy or speckled appearance caused by high ISO settings or poor lighting conditions.

A histogram is a graphical representation of the distribution of tones in an image. It helps photographers analyze the overall brightness, contrast, and tonal range of the image, allowing them to make informed adjustments during post-processing.

Adjusting the exposure is a non-destructive editing technique because it does not permanently alter the original image data. The adjustments can be easily reverted or modified without affecting the original image quality.

A graduated filter allows photographers to selectively adjust the exposure in different parts of an image. This is particularly useful for balancing the exposure between the foreground and background, or for creating a more dramatic effect by darkening or lightening specific areas of the image.

Sharpening is typically not considered a creative effect in event photography post-processing. It is a basic editing technique used to enhance the clarity and detail in an image.

A radial filter allows photographers to selectively adjust the exposure, contrast, saturation, or other settings in a circular area of an image. This is useful for creating a focal point, drawing attention to a specific subject, or enhancing the overall composition of the image.

JPEG (Joint Photographic Experts Group) is a commonly used file format for saving event photography images after post-processing. It offers a good balance between image quality and file size, making it suitable for sharing and online distribution.

A noise reduction filter is used to remove unwanted noise and grain from an image, particularly in low-light or high-ISO situations. By reducing noise, photographers can improve the overall image quality and clarity.

Levels is primarily used for adjusting the overall brightness and contrast of an image, rather than specifically for color correction. Color Balance, Hue/Saturation, and Vibrance are more commonly used tools for adjusting the colors in an image.

A sharpening filter is used to enhance the clarity and detail in an image by increasing the contrast between adjacent pixels. This can make the image appear sharper and more defined, particularly when viewed at larger sizes.

Microsoft Paint is a basic image editing program that is not typically used for professional event photography post-processing. Adobe Photoshop, Adobe Lightroom, and Capture One Pro are industry-standard software programs that offer a wide range of advanced editing tools and features specifically designed for photographers.

A vignette effect is used to create a darker or lighter border around the edges of an image. This can be used to draw attention to the center of the image, create a sense of depth, or simply add a creative touch to the overall composition.

Color Grading, Split Toning, and Vibrance Adjustment are all common techniques used for enhancing the colors in event photography post-processing. Color Grading allows photographers to adjust the overall color palette of an image, while Split Toning adds different color tones to the highlights and shadows. Vibrance Adjustment increases the intensity of the colors in an image without affecting the overall saturation.

A lens correction filter is used to correct distortions caused by the camera lens, such as barrel distortion, pincushion distortion, and chromatic aberration. By applying lens corrections, photographers can ensure that their images are accurate and free from these common lens distortions.

PNG (Portable Network Graphics) is not commonly used for saving event photography images before post-processing. JPEG, TIFF, and RAW are more commonly used formats for capturing and storing high-quality images with minimal compression.
