Taking pictures with a digital camera is like shooting slide (reversal) film: you have + - 1/2 F stop exposure latitude.
This means if you overexpose by 1/2 stop you will get "washed out" highlights that must be fixed (sometimes not possible) by digital editing software, or 1/2 underexposed very dark images that also must be corrected using digital imaging software.
Since 2010 the newer low end and point and click digitals have become better at preventing the washing out and have maybe a 1 stop over from what is the correct exposure and still maintain a good image - a 1 stop range error margin compared to color negative and B&W films 3 stops.
I found that by permanently setting my camera to underexpose by a 1/3 stop prevents highlights from being washed out.
Anytime you must use software to correct for improper exposure you will lose quality.
Most digital cameras allows you to take video with them. My first digital camera, a Nikon N5700 is what I used to video the Lancaster flying in the UK other aircraft at the Reno Air Races performed this trick. My point and shoot Nikon S550 does 720 quality and my high end D90 takes video at the 1080P quality - even the phones you get through most Verizon, Sprint and T-Mobile prepaid plans now have cameras with video capability. This is a whole new area where some still camera "rules" do not apply. Other sites are more specialized and better suited to tell all about making movies so this list will cover a few basic ideas.
When possible, try and take movies using a tripod. If not, then practice, practice, practice, rotating your whole body when filming so as to avoid camera shake by locking your arms against your body and then rotate.
