Abstract: An image editing application with a novel color modification slider tool adjusts one or more color attributes of different pixels differently when moved in one direction, and adjusts one or more color attributes of the same pixel differently when moved in another direction. This tool produces non-photorealistic effects by treating differently the highly saturated and lowly saturated pixels of an image. Specifically, the saturation tool performs either (1) a positive de-saturation effect that de-saturates the low saturated pixels of an image while enhancing the saturation of the high saturated pixels, or (2) a negative de-saturation effect that de-saturates the high saturated pixels of the image while leaving intact or slightly modifying the saturation level of the lowly saturated pixels.

Abstract: A method and apparatus for generating a grayscale image. The method and apparatus receive a single value. From the single value, the method and apparatus generate a set of grayscale weighting values. The method and apparatus generate the grayscale based on a color image and the set of grayscale weighting values. By limiting the number of values to a single value, the method and apparatus prevents a user from arbitrarily selecting a number of possible weighting values which could result in a grayscale image that is too dim or too bright. This single control method and apparatus quickly and efficiently produces a grayscale image that is neither too bright nor too dim.

Abstract: Some embodiments of the image editing and organizing application described herein provide an automatic enhancement process that includes vibrancy adjustment. The vibrancy adjustment increases the saturation of multiple pixels. The saturation of each pixel is determined by subtracting the lowest component value from the highest component value. The process determines an overall saturation of the image using a histogram. The histogram is generated using doubled saturation values for pixels with blue and green as the highest component value.

Abstract: A method and system for providing a dynamic grain effect tool for a media-editing application that generates a grain effect and applies the grain effect to a digital image. The application first generates a random pixel field for the image based on a seed value. The application then generates a film grain pattern for the image by consecutively applying a blurring function and an unsharp masking function, based on an ISO value, to the randomly generated pixel field. The application then blends the grain field with the original image by adjusting each pixel based on the value of the corresponding pixel location in the grain field. The application then adjusts the grain amount in the previously generated full-grain image by receiving a grain amount value from a user and applying this value to the full-grain image.

Abstract: A method for generating and/or modifying a grayscale image. The method receives a color image. The method generates an initial grayscale image based on attributes of the color image. The method generates a set of hue values for all the pixels in the grayscale image based on color values of the pixels in the color image. The method defines a hue curve across the range of hue values based on input received from a user interface control. The method modifies the grayscale image based on the hue values and the defined hue curve across the range of hue values.

Abstract: Some embodiments of the image editing and organizing application described herein provide an automatic enhancement process that includes a shadow lift adjustment. The process takes an input image and enhances the contrast of darker parts of the image. The process uses a structure histogram to determine an amount of shadow lift adjustment to apply to the image. The process tempers this adjustment based on an International Organization for Standardization (ISO) value of the image.

Abstract: Some embodiments provide a method of automatically color balancing an image. The method receives a selection of a user interface (UI) item to automatically color balance the image using a color balance tool that includes several color balance modes. In response to the selection, the method analyzes the image based on a set of criteria. Based on the analysis, the method automatically selects a color balance mode from the several color balance modes of the color balance tool. Upon selecting the color balance mode, the method uses the color balance mode to automatically apply a set of color balance operations to the image.

Abstract: Some embodiments provide a novel user interface (UI) tool that is a unified slider control, which includes multiple sliders that slide along a region. The region is a straight line in some embodiments, while it is an angular arc in other embodiments. In some embodiments, the unified slider control is used in a media editing application to allow a user to modify several different properties of the image by moving several different sliders along the region. Each slider is associated with a property of the image. A position of the slider in the region corresponds to a value of the property associated with the slider.
