Camera result with differing aspects

I have a square PictureBox and having trouble with differing aspect ratios when loading images from the Camera control, all with the same aspect ratio, square.

This one is a square image (circle on a transparent square obviously) 512 x 512

This one is also 512 x 512 but gets stretched for some reason. Can anyone shed light on why this happens?

From what i see,2nd image is also “square”,just that the distance from the camera to the pic is different.any thoughts,appstudio users?best rdgs,tst

If you take photo at certain angle,the pic will get streched.

Both images are files on my pc, both 512 x 512. Both created in photoshop, saved as png, same quality.

Oh,i am defeated,no ideas now.any comment to this thread,anyone?
