The former applies a perspective adjustment to each image the latter repositions and/or sizes the image layer.Ĭheck Live Alignment to allow the above perspective adjustment to be made non-destructively (this may affect performance depending on size and number of images to be stacked). (Optional) Uncheck Automatically Align Images to manually align images later in the Layerspanel.Ĭhoose a Perspective or Scaling operation from the menu to allow for successful auto-alignment. Click Open to add the images to the stack list. Could be used with stacked video frames (within the same scene or shot).įrom the dialog, click Add to locate and select your images for blending. Entropy-analytical: represents the number of bits required to encode information in the stack. Darker results represent greater noise and less tonal uniformity (more pixels further away from dominant grey level). A brighter result represents low noise levels and a tonal uniformity (most pixels at dominant grey level). Kurtosis-analytical: detects the peakedness of an image.Can be used to determine tonal and spatial differences between images. Skewness-analytical: highlights edge detail and indicates the intensity of pixel value distribution.More intense distributions are shown very clearly. Variance-analytical: as Standard Deviation, indicates how pixel values are spread between images.Useful for object removal as it clearly indicates areas that will be averaged out with a Median operator. Standard Deviation-analytical: measures the distribution of information between the images.Usually results in overexposure, but can be used to lighten very underexposed imagery. Total-produces the total value of pixels from each image. Can be used to increase tonal range if used with bracketed exposures.
