How to take a one-inch photo with a digital camera

If you have a tripod, stand up and shoot vertically, so that you can make full use of CCD. If you are not familiar with photography, I suggest you find a room with a window. The window is bigger and the distance between the two sides is more than one meter, so that it will not be disturbed by ambient stray light. Let the person being photographed face the window, your back is right, and don't let your shadow cast on the person being photographed. The camera uses the highest pixel and the sensitivity is ISO 100. Just use the automatic photo mode. If it is not good, use manual or shutter first. Let people stay in the middle of the picture with a proper distance above their heads. Just take a picture of the position of the second button below, so that the workload of later cutting will be better. I don't know what color you want to use as the background, but don't leave people more than half a meter in natural light, or the contrast with people will be too great.

After shooting, import it into the computer, open it with PS, set the cutter, the size of one inch is 2.5*3.5 cm, and the resolution is 300 pixels/inch, then typeset and print.

I don't know what kind of printer you use. Some printers have the function of typesetting and printing ID photos, so they are different. However, I recommend that you adjust it slightly in the computer, and the effect will be much better.
