that fills the holes with some unobtrusive or neutral color, but usually a better solution is to crop the image. The greater the rotation, the more cropping is required, so it is best to get the camera interest one-third of the way across the image, both widthwise and heightwise. To crop an image, activate the Crop tool in the Toolbox, or by pressing the "C" key (capitalized) while inside the image sweep out a crop rectangle. It will also pop up a dialog that allows you to adjust the dimensions of the crop region if they aren't quite right. When everything is perfect, hit the Crop button in the

However layers. But there are more options than that… Cropping and resizing the canvas You can crop and image with the Crop Tool, to cut away extra space and improve the composition. Trimming Using Image ‣ Trim resize the canvas to the extent of this layer. Image ‣ Trim to Selection is a faster cousin to the crop tool.
