  • The Placement Option in the Video Preview dialog box determines how an image appears in a display device.

Understanding file properties

  • High Dynamic Range (HDR) images are 32-bits-per-channel images that represent the entire dynamic range of the visible world.
  • The HDR image represents all the luminance values or radiance that can be observed in a real-world scene.
  • Photoshop enables a user to adjust the preview so that the monitor correctly displays an HDR image.

Working with automation

  • The Merge To HDR command (File > Automate > Merge To HDR) is used to combine multiple images (each image taken with different exposures) of the same scene in a single HDR image.
  • The Equalize Histogram tonal mapping method in the HDR Conversion dialog box compresses the dynamic range of the HDR image into the contrast range of a normal 16 or 8-bit image.
  • The Exposure and Gamma tonal mapping method enables a user to manually adjust the brightness and contrast of the HDR image.
  • The Local Adaptation tonal mapping method adjusts the tonality in the HDR image by calculating the amount of correction necessary for local brightness regions.

Working with filters

  • The Reduce Noise filter reduces the granular appearance of images.
  • The Strength setting of the Reduce Noise filter reduces noise by smoothing out the random variations in brightness levels.
  • The Remove JPEG Artifact option enables a user to remove problems with low quality JPEG image.
  • The Preserve Details setting of Reduce Noise filter enables a user to bring back the details in an image that the Strength option rounds off.
  • Gaussian blur occurs when an image is out of focus.

  • The Smart Sharpen filter enables a user to sharpen some parts of an image more than others.
  • The Fade Amount determines the strength of sharpness of either shadows or highlights.
  • The Vanishing Point filter (Filter > Vanishing Point) is used to manipulate image contents that conforms to the perspective of the image.
  • When using the Vanishing Point filter, a user needs to define the four corner nodes of the plane surface in an image. In general, the corner node placement, the bounding box, and grid are blue. However, if they turn to either red or yellow, it indicates that there is a problem with the plane.
  • Selecting Off Healing mode while using stamp tool in Vanishing Point filter prevents the cloned content from blending with the color, lighting, and shading of the surrounding pixels.
  • The Lens Correction filter is used to correct common lens defect such as barrel distortion, pincushion distortion, vignetting, and chromatic aberration.
  • Vignetting is a common lens defect in which an image’s brightness or saturation at the edges, especially the corners, is less as compared to the image center
  • Vignette Amount slider in the Lens Correction dialog box enables a user to darken or lighten the edges of an image.

  • In ImageReady, select the Unify Layer Style button of the layers palette to apply the changes made to a layer style to all frames in the animation.
  • In ImageReady, selecting the Paste Over Selection option of the Paste Frames dialog box replaces the configuration of selected frame with the copied frames and adds new layers to the image that contains the contents of the pasted frames.
  • For creating some special types of animation, such as changing the color of an object or completely changing the content, a user needs to add layers that have new contents in the Layers palette.

Working with PDF documents

  • The Place command (File > Place) is used to place artwork into a new layer in an image as a Smart Object.
  • An image can be saved in the Photoshop PDF format by using the Save As command.
