When it comes to webcams, don't get a webcam less than $50, otherwise you are wasting your money. You will NOT look good AT ALL.
Always, $50 or above.
I personally, would suggest Logitech.
The Webcams included inside of a Laptop is generally AWFUL, I don;t care whether you are using a Windows/IBM or an Apple, they are just trash!
The reason is because you can't adjust the angle of the camera.
So, even if your laptop came with a cam installed, GET A SEPARATE ONE ANYWAY!
This is pretty important, because some people conduct interviews for a job via webcam now, or give interviews on TV via webcams. This can make or break your 1st impression.
Using your webcam in a way that won't make you look too old, too fat, too dark, or too bright is the trick.
The #1 best suggestion I have for you is to mount your camera on top of your monitor, and angle it down at your face. Keep adjusting the camera until you look good enough in your view of yourself. Generally, you will want to see your jaw line, or jaw bone.
NEVER mount the camera angling upward. This will make you look too fat, in some cases too young, or in others too old.
If you have webcam filters, play with those, and be aware of your lighting. Daytime will be different from Night Time.
Now, here are a few tricks I did with Webcam Photos:
Several people didn't know these were webcam photos. Several also didn't believe they were Webcam photos.
But, they are.
I just adjusted them in Photoshop.
So, there's many things you can do with the right software, if you know what you are doing.
But, You will need to make at least a decent composition first.
So, as you can see, I use my artistic skills with my photography all the time.
