Changing the output size of an image.

I have a Canon PowerShot Elph 100 HS. I am taking pictures at 12M 4000x300 ~ for prints up to 16"x20". When I download them into Photoshop the measured image in inches is something like 90"x110". I cannot figure out how to change the internal setting on the camera so the download image is not so huge. Please help

Changing the output size of an image in Photoshop

I'm not sure if the resolution/dpi/ppi can be (re)set in your camera, but (re)setting it in Photoshop is pretty easy:

Image ==> Image Size, change the number in the third box labeled "Resolution" next to "Pixels/Inch" to something in the range of 200-300. (300 is generally accepted for professional prints, 200 for home/consumer prints. And note that a value of 200 pixels/inch will give you a 20x15" print from a 4000x3000 file; I'm assuming 300 was a typo for 3000 since you also said 12MP.)
