Not only can new types of faint objects be discovered, but deep images of bright galaxies are very valuable, too, since they reveal faint signs of past galaxy collisions, the tidal features. Such \u201carcheological\u201d record can be exploited for investigating how galaxies formed. In the MATLAS survey, we obtained extremely deep images of 177 nearby massive elliptical and lenticular galaxies using  the 3.5m Canada-France-Hawaii Telescope.<\/p>\n\n\n\n<!--more-->\n\n\n\n<p> In our contribution, we will present the various types of objects and features seen in our images, for example tidal features, faint star-forming regions in otherwise quenched galaxies, or faint dust clouds in our own Galaxy.
