I have just downlaoded various pics from my Digi Cam and also watched some video that i took earlier today. They are Grainy and of poorish quality to what i would expect.

Would this be becaue of the lighting indoors where the pics/vid was taken?

I have not used my video camera outside in daylight yet but i will be trying this tommorrow.

Could be. If your cameras have automatic ISO they will probably have set themselves to the highest available sensitivity in the low light environment, which would cause you increased noise (looks like grain).

I'm no expert, but my experience has been that you get much better results in brighter conditions, also my DV cam has sports modes (which I suppose are just a faster 'shutter' speed) which help when there's a lot of movement in the picture.

Yes it will be. You'll need extra lights to get a better pic.

In low lights, camcorders boost the signal automatically by amplifying it, but the trade-off is noise as you have seen. Digital can work wonders bu not miracles!

Using a 'sports mode' means the camera uses a faster shutter speed but a larger aperture (so the overall exposure is the still correct). Hence you get frozen sportsmen but less depth of field. To get more light in over and above any 'auto' setting, you'll have to use Exposure Compensation (+EV) or set it to Manual.

Best just to put some lights on though!

I have taken many pics using my digital camcorder (Sony IP55) The image is only just over 1mp. The pics look great on my PC until I use zoom in low light when they deterioate quite badly.

I have no problems though when filming in any conditions.
