Laptop cameras are often USB devices. Some laptops disable cameras (for security) with obscure function keys or possibly BIOS settings. Since laptops are power-challenged, they usually turn the camera off when it is not being used. You should see a USB camera device with lsusb if the camera is active. You can search for the linux module using the USB ID's. Searching for linux configuration reports for your laptop model may give useful details. A recent model laptop may not yet have a linux camera driver.
https://wiki.ubuntu.com/SkypeWebCams has a long list of cameras (including integrated laptop models) that are known to work in linux.

This my laptop (4 year old) QE62 6QD-670XFR (apache pro)
Made by MSI, see https://forum.ubuntu-fr.org/viewtopic.php?id=1976971&p=4 says
Après 2-3 galère, idem Ubuntu 18.10 installé sur un MSI GP62 6QF.
Tout est fonctionnel: - La caméra, qu'il faut activer avec Fn+F6 ===> Il faut l'activer pour avoir le micro intégré (sur Windows le pilote gère les 2, donc rien d'anormal). - Les fonctions Fn essentielles comme le rétro éclairage du clavier, le volume du son et l'éclairage de la dalle - Le trackpad Google translation pour les Anglais:
After 2-3 galley[sic], ditto Ubuntu 18.10 installed on an MSI GP62 6QF.
Everything is functional: - The camera, which must be activated with Fn-F6 - It must be activated to have the microphone integrated (on Windows the driver manages the 2, so nothing abnormal).
- Essential Fn functions such as keyboard backlighting, volume of sound and slab lighting - Trackpad

Do other Fn keys work as expected? Does you system have a Fn Lock key? Did you check for the USB device? Fn+F6 may not do anything if the camera has been disabled in the BIOS. The drivers may not load automatically, and may not even be installed without further work.
The steps are:
1. turn on camera (BIOS and/or Fn key) 2. what is the USB device info (vendor and product ID's)? 3. which kernel module supports your camera? 4. is the module included in Fedora?
Install "guvcview", if you have a camera and it supports it then it should find it. It should support any uvc compatible camera and almost all of the last 6 years of cams have been uvc.
if fn-f1 is caught by gnome that implies that maybe fn-f1 == f1 and that non-fn presses may going to the bios.
I have seen laptops default to function keys to the bios and fn-f1 = function key to os, often the default is setable in the bios.

I don’t think you are hitting the right key sequence. Pressing the F1 key alone brings up the gnome help, Fn-F1 does something hardware-dependent.
Fn-F6 (pressed in that order, keeping the Fn pressed down) should activate and deactivate the camera.
You can test this by pressing the other hardware buttons like the key for keyboard backlight, screen brightness and volume, which are activated with Fn and the marked F keys.

So you don't have brightness or sound level control? This is rare in my experience, but that has been with products from large vendors (Apple, Lenovo, Dell, etc.).
What is the normal function of Fn+F1 (usually there are icons to indicate the purpose of the Fn+Fn keys) on the key tops.
As Roger mentioned, check for a BIOS setting to enable the Fn keys.
It is a built in camera HD type (30fps@720p)
If it is a USB device you need to find the ID's with lsusb once you have it turned on. It is possible that the camera can be turned on via ACPI.
I tried to check from the bios, but I cannot find a camera.
There may be an option to enable the Fn keys. Ubuntu tends to support a wider range of hardware without extra work than Fedora, but if Ubuntu can enable the camera there should be a way to do it Fedora. You could try booting a live Ubuntu USB key. If the Fn keys work, check the kernel command-line and loaded modules for something that enables the keys.

This is not generally true on newer laptops (and macs). The default of pressing the key is the special function. To get an actual function key (F1, etc), you have to use the Fn button. Sometimes there's a BIOS setting to swap that.

Yes, I enabled it.
fn+f6 generates (in a gnome-terminal) ~ fn+f10 opens a firefox window option fn+f7 opens a window when I do it from firefox There are the only fn+fx which work now. But, I do not remember, but I obtained that fn+f12 generates the sleeping mode. Maybe when I disabled the fn/win option in the bios. I am going to check
f6 seems to generate the same sequence. ~
