# Manually-Created Matches
You can create your own matches from within the **Match Explorer:**
To do so, first select two images in the bottom right quadrant of the screen (you may need to zoom using the mouse wheel in to see the images well). In this window, **Left click** to select the first image (green), and **right click** to select the second image (purple). By default the forward facing receptor will be displayed - you can alternate through the different receptors by pressing the number keys **1, 2, 3, 4,** and **6**.
The two selected images will appear in the top left and right windows.
Next, click **Add Match** in the bottom left window. With the match selected in the bottom left window, identify the feature in both image windows by **Left Clicking**.
Once you have created a sufficient number of matches (approximately 10-20), you can click **Calibrate** and CameraSnap will proceed with Calibration using the available feature matches. Review the [CameraSnap report ](/spatialexplorer-8-and-9/user-interface/toolbars/workflow/camera-snap/camerasnap-reports.md)to ensure a proper calibration was achieved.
