Guest phantomguy1 Posted March 5, 2009 Report Posted March 5, 2009 1. Just wanted to know if there is a way if you want to focus on something closer and make the background blurry. 2. Also to add more color to the pictures because my pictures always seemed washed out ... I will edit the post if I have more questions but thats all for now. Thank you!

As a Broadcasting Engineer I can tell you that you are talking about something called Depth of Field. DOF is very dependent on the size of the imager. In tiny cameras such as these, the imager is really small and the math involved just wont allow for good shallow depth of field. This is very common on small imaging device cameras, as the folks buying those fancy 1 chip pocket HD cameras are finding out about now. You need an imaging device in the range of a 16mm film camera image area to start with and up to 35mm and beyond to really get it. To do that you need a larger lens that is much further away from the image pickup device. Short answer, can't do it under normal conditions. The lower light the more the iris is open on the camera but these devices don't have an iris anyway so that won't help either. Cameras like this control the light entering the imager by controlling the shutter speed generally, coupled with an artifical ASA setting that is. Sorry, it does take nice sharp images in bright light though. Sean Edited March 5, 2009 by DeepBlueEditor

Maybe I might get it..... but not until Summer when the weather is nicer for picture taking. Thanks for the info!
