Set your phone to snap a picture on voice command (most of them let you do this.) You can try letting the phone snap a picture automatically, or set your phone's camera to manual focus, and set the ISO and desired time exposure(s) for the image. Make sure you don't have any stray light or lay a black cloth over the assembly. It works surprisingly well. **Q: Is it Parfocal** A: Dear customer , Thanks for your contact.
