Can I take pictures with a camera or video camera with the size of 10-20KB and the height and width of 170* 130 pixels?

1, it is impossible to directly take a photo of 170* 130 pixels, because there is no such low setting for the shooting parameters of any camera and camera software, so we have to take it first and then cut it off with software (such as photoshop). Generally, self-timer will have some deviation because of framing, and it will almost certainly need post-processing software editing.

2. You can shoot by yourself, because you only shoot the head, deal with the light layout and background (the wall at a certain distance can be stretched with a cloth of suitable color, or you can directly use a solid color wall). After observing and positioning, you can delay or shoot with a remote shutter, but if you don't have a photographic basis, you may not have enough position, inaccurate focus and unsatisfactory light. Fortunately, digital cameras don't need to spend money on film, and you will always get a photo you are satisfied with if you shoot more and try more.
