Rotation is a function to rotate an image. With rotation function, a rectangle with the original image ratio is automatically trimmed to enlarge the size of the image to the original one. This process maintains the number of pixels after rotating when the image is developed, and prevents from resolution reduction after rotation. Since this process prevents resolution reduction after rotating, you can use rotation function at ease. This function works well on a picture you took slightly at a slant. This software allows -45degree to +45degree rotation. Too big rotation loses a large part of the image. In this case, use the "expansion" in the trimming functions to display all pixels lost in the rotation process and you can extract the area you need. >See 'Expansion of trimming.'

Digital shift enables deformation effect of the picture taken by a shift lens. As this function controls perspective, you can correct the narrowed upper area in the picture of buildings.
