## Step 3: Preprocess and merge the photos The next window lets you specify options for preprocessing and merging the photos. If your photos were taken hand-held, check the Align source images box and select the By matching features method. The three photos of the Grand Canal were taken using a tripod, but we still check the alignment option to correct for small alignment problems that may happen even with a tripod. If your scene includes moving objects or people, check the Remove ghosts option. If the bracketed photos you loaded are RAW files, check the Reduce noise option. You may also check this option with jpeg or TIFF files. Click on Preprocess to proceed till the next step.
