    Study Notes

    Introduction

    • Images directly from cameras may require adjustments.
    • Common issues include brightness, darkness, and blurriness.

    Brightness & Contrast

    • Brightness affects the overall light and dark levels in a picture.
    • Increasing brightness can lead to noise, or graininess, especially in dark images.
    • Contrast enhances the difference between light and dark areas, making them more noticeable.
    • Excessive contrast can lead to loss of image detail.

    Color Corrections

    • Saturation controls the intensity of colors in an image.
    • Increasing saturation makes colors appear more vivid, while decreasing it dulls them.
    • Removing all saturation results in a grayscale image.

    Sharpening

    • Sharpening enhances the edges of objects, making the image appear clearer.
    • Over-sharpening can result in unnatural edges and increased noise.

    Image Noise

    • Image noise causes graininess in images.
    • Noise reduction tools can minimize graininess, but excessive use may lead to blurring and detail loss.

    Automatic Adjustment Tools

    • Automatic adjustment tools analyze images and apply corrections for improved appearance.
    • Tools like Auto Fix in Pixlr X and Auto Tone, Auto Contrast, and Auto Color in Photoshop can enhance images.
    • Manual adjustments can be made after using automatic features for finer control.

    Other Common Corrections

    • Red eye removal tools correct red eyes caused by flash.
    • Touch-up tools allow for blemish and unwanted detail removal.

    Lesson 4: Fixing Common Problems

    • Many digital camera images require editing to perfect.
    • Pixlr X and Pixlr mobile app are free tools to assist in editing.
    • Brightness and contrast determine the overall light and dark levels of an image.
    • Increasing brightness can cause graininess or noise in the image.
    • Increasing contrast enhances the difference between dark and light areas in an image, making dark areas darker and light areas lighter.
    • Excessive contrast loss can lead to a loss of detail.
    • Color saturation affects an image's vibrancy and richness of color.
    • Boosting saturation enhances colors, while reducing it mutes the overall color.
    • Excessively boosting saturation can lead to unnatural and jarring colors.
    • Sharpening enhances image clarity by sharpening edges of objects in the image.
    • Over-sharpening can cause unnatural edges and an increase in image noise.
    • Image noise reduction eliminates graininess in images.
    • Noise reduction exceeding optimal levels can blur the image, causing a loss of detail.
    • Automatic adjustment tools analyze and correct overall image appearance.
    • Specific automatic tools include Auto Tone, Auto Contrast, and Auto Color.
    • Red eye removal tools correct red eye caused by flash in photos.
