I just acquired an amateur camcorder (Samsung HMX-Q10) that has only a few settings available, most of them are automatic.
I tried to shoot a video of me playing a bass guitar cover but it seems that the image is always slightly out of focus. I'm just slightly blurred but with HD image this kind of detail is really noticeable.
Shooting environment : me standing in front of the camcorder (~2-3 meters) with an instrument, in my appartment (walls mostly white), natural winter/cloudy lighting, white / bright brown background, black clothes, red guitar.
Cam specifications/settings : Full HD 1920x1080/50i, Exposure Value : 0, Shutter 1/50 of a second (there is a "low light mode" that set it to 1/25 but it adds colored artifacts).
I can't notice that the image is blurred on the camcorder small monitoring screen, but when I open the video on the computer it is more obvious (especially because the guitar brand label is blurred), so without proper feedback it is quite hard to manually set the focus.
So what can I do to help the autofocus ?
What can I change in the shooting environment to improve its accuracy ?
I'm thinking, maybe the lighting, the colors (background / clothes), some camcorder settings, another element I forgot ?
