Capture One uses the concept of 'Collections' to group images together, in the example shown below this happens to be images in a particular folder, although in reality images from various sources can be grouped into a collection. The default layout has the collection pane (thumbnails) on the left, preview / work pane in the center and function tabs on the right. All panes can be resized or collapsed, you can also work in full screen mode without a titlebar. The one big strength Capture One DSLR has over the Canon software is that all adjustments happen in (almost) realtime. That means you can make a grey balance adjustment and see the change immediately, this is far better than the rather slow-to-change Canon FIle Image Viewer. You can alternatively switch to a horizontal view (press F8) which shifts the collection pane to the bottom of the window. This is probably a more useful layout for landscape photography.
