사진을 잘 모든 각도에서 잘 찍어서 올려야 하는 듯 하다.

Here's some tips after trying and failing at this a dozen times:

1. Don't try to photo scan any furry, thin, or reflective materials. Any reflections will confuse the depth map of the software.

2. Have a clear path in your mind of where you are going to take pictures from. The basic shape of the camera angles should be a large dome that includes a lot of surroundings of the object (this layer makes it easier for the software to determine which side your closer angles are shooting from), a medium dome that centers the object and the object almost reaches the edges of the image frame (this gives the program most of the shapes), then a very small dome where you get close enough to see 1/4-1/8 of the object, to get more detail when texturing.

3. Any parts that jut out of the object should have their own additional domes of pictures that cover every angle.

4. The scan quality increases proportionally to the amount of pictures taken. I had to take 70-100 pictures to get a quality I was happy with.

5. Don't include blurry pictures or pictures taken at a weird angle.

6. A good way to know if your camera is good enough for photo-scanning is the size of the pictures it produces. At least 1.5MB is necessary and 2.5MB+ is optimal.

7. Only take outdoor pictures when it is cloudy and indoor pictures in places where the object does not receive direct lighting.
