    Default DPI ? for powershot SX20IS

    I have tried to change settings and no matter what I do when I open an image in paint shop pro I can only get 180 dpi in the original image. Is there a way to get at least 300 dpi off the camera? I bought this camera because I am an artist and am trying to get high res photos of my paintings.

    I have been fighting with this for a long time and would really appreciate some advice. Thanks!

    The SX20IS is a 12 megapixel camera. If you're shooting at maximum resolution you should be able to get 300 dots per inch unless you're blowing up the picture to more than 14 by 9 inches.

    You can't get 300 dpi off-camera, the images on almost all cameras are at 180 dpi. But this shouldn't matter as dpi is relative to what print size you want. If i understand the OP correctly, with the sharp prints he is seeking, it would be a simple case of resizing the images by changing the dpi value.

    For example, a 4:3 aspect ratio 10MP image at 180dpi would print out at 20.2x15.2". 300dpi would print out at 12.1x9.1". Extreme 2880dpi resolution would result in a 1.2x0.9" print out.
