If you take the out of the camera orginal to a printer and say have a 8 x 10 printed, it would be horribly cropped, and the image would be yuck. It my menory serves me that camera is a 10 megapixel, the size of the print as out of the camera would be over 48 inches on the longest side.
Take your image into elements, first make a duplicate and close out the orginal (never work on the orginal).Now go to image>image size and where it says 72 dpi change that to 300 and see how the overall size of the images changes should be close to a 12 x 8. Now if you want an 10 x 8 change the sizes in the boxes with the inches. All you need to do is change the largest number. See how close to an 8 x 10 you can get. The dpi will be large but that won't hurt anything as far as printing goes. At least it doesn't for me. I hope you can understand me but if you need I can post some screenshots.
