+En utilisant `v4l2-ctl`, on peut vérifier les modes disponibles pour une caméra :  
+
+```
+$ v4l2-ctl --list-formats-ext -k

+## Module caméra Raspberry Pi 
+
+Voir ici pour les résolutions disponibles pour les modules V1 (5MP) et V2 (8MP) :  
+
+[[https://picamera.readthedocs.io/en/release-1.13/fov.html#sensor-modes]]  
+
+Le module v3 supporte les [modes suivants](https://github.com/raspberrypi/linux/blob/rpi-5.15.y/drivers/media/i2c/imx708.c) :  
+
+```
+mode_4608x2592_regs      (4608x2592)
+mode_2x2binned_regs      (2304x1296)
+mode_2x2binned_720p_regs (1532x 864)
+mode_hdr_regs            (2304x1296)
+```
+
+On peut aussi utiliser la commande `libcamera-hello --list-cameras` pour obtenir des infos sur le module connecté :  
+
+```
+Available cameras
+-----------------
+0 : imx708 [4608x2592] (/base/soc/i2c0mux/i2c@1/imx708@1a)

+```
+
+## Showmewebcam
+
+La résolution maximale est de 1600x900.  
+
+## Réflexe numérique 
+
+En utilisant gphoto, on peut trouver les résolutions disponibles (ici avec un nikon D3000):  
+
+```
+$ gphoto --list-all-config | grep imagesize
+/main/capturesettings/imagesize
+$ gphoto2 --get-config=/main/capturesettings/imagesize
+/main/imgsettings/imagesize
+Label: Image Size

+Choice: 0 3872x2592
+Choice: 1 2896x1944
