I want to take another photo today

This is already the third round of the competition. Alas, I don't want to raise my requirements in advance for work efficiency. I can only find my own photo standards.

1. image File requirements: digital photos are compressed images in JPG format. The compression quality is sparse and 70 (0-100). Generally, the file size of a photo is between kb and the image length and width are as follows: 441 pixels (high) x 358 pixels (WIDE), 350 dpi resolution, 24-bit real color.

2. portrait size and position: the portrait is horizontally centered in the rectangular frame of the photo. The face width is 207 + 14 pixels, and the top of the head is 7 to 21 pixels from the top of the photo, the bottom edge of the photo is subject to the just-exposed clavicle or shirt tip.
