d) The camera should generally remain relatively stable when shooting, and the subject and key parts of the shooting should occupy more than 2/3 of the total lens;

e) Shooting of autopsy, anatomical, and organ examinations should avoid subject deformation; if it is necessary to reflect the damage and tissue changes Close-up shots should be taken when the blood vessel is changed, and a still picture of 5s ~ 7s should be maintained;

f) Filming wounds, injuries, punctures on clothing, ties, wounding tools, etc. should be scaled;

The ruler shall comply with the relevant provisions of 3.1 ~ 3.10 in the GB/T 23865-2009 Proportional Photography Rules;

g) In the same case, if more than one unnamed body camera is submitted for inspection at the same time, a distinguishable nameplate shall be placed so as not to affect the subject.

In the case, take pictures with the signage;

h) The light used for shooting should be such that the subject is not shadowed, and the subject reflected by the detail is not reflective.

8.2 Specific requirements and camera methods

8.2.1 Specific requirements and shooting methods for the basic content of autopsy video.

a) When the basic content of autopsy is taken, the camera generally adopts a top-down angle;

b) The original clothing of the corpse in front, back, and nude front, back, and back should be continuously reflected on the whole body. Camera bit should be at appropriate positions on both sides of the corpse, higher than the corpse and maintaining an overhead angle of about 45 ° with its lying position, using push or pull, Shoot from whole to partial or from partial to whole. Or use horizontal pan and mid-range picture to shoot from head to foot. or Use shift and mid-range picture to move from the head to the foot to shoot on the horizontal axis of the lens;

c) The original condition of the corpse should be a close-up shot pushed from the middle shot to the hands, soles or soles;

d) Nude head and face photography, using a medium shot, the optical axis of the camera lens should be perpendicular to the head and face of the corpse, with the mouth and nose as the focus, on the head Push to pull from face to chest.

8.2.2 Specific requirements and shooting methods of autopsy camera.

a) Photographs of corpse features should be taken continuously from the center to the periphery and from the head to the feet;

GA/T ××××-××××

b) The still images and moving lens images should be combined with each other, and used flexibly, and the camera angle should be appropriate during autopsy. Shoot various when corpse features, you should first push to the feature point, keep the still picture for 5s ~ 7s, and then pull and shake or move to the next feature point;

c) The shooting of the individual characteristics on the corpse should be pushed to a close-up shot, to maintain a still picture of 5s ~ 7s, and then pulled to its body part;

d) Shooting of small features such as bleeding spots (plaques) around the eyelid, conjunctiva, eye area, face, and other areas can use a close-up device, and 4.2.5 of GB/T 29349-2012;

e) When photographing sulci or other injuries on the neck, remove interference hair and dirt according to the specific situation, in front of the neck, on both sides of the neck and at the neck, Use push, pull and shake or move to reflect the damage and its location;

f) For the shooting of subcutaneous bleeding, attention should be paid to adjusting the angle between the camera and the light source to accurately and comprehensively record its shape and characteristics.

To achieve the purpose of reflecting the characteristics of the wounded object;

g) The shooting of sharp or blunt wounds should reflect the shape and characteristics of wounds such as wound angle, wound margin, and bridge between tissues. While using the appropriate Scenery, reflecting the body part where the wound is located;

h) When photographing the clothing, trademarks, signs, tears, and remnants of the deceased, if any dirt is unclear, first photograph the original condition and treat the object.

Card extraction and other work is completed, after cleaning and placing on a contrasting substrate, using a combination of push and pull methods, again Take front and back shots. The clothing and characteristics of the unknown body should have a still picture of 5s ~ 7s;

i) The bundle should be shot in situ and from multiple angles. Through pushing and pulling, it should reflect the characteristics of knotting and direction. After removing it, put it according to its color.

Put it on a contrasting substrate before shooting.

8.2.3 Specific requirements and shooting methods of anatomical examination camera.

a) The photographs of the positive parts of the body seen in the anatomy should be taken from the outside to the inside and from the whole to the part;

b) Deep wounds or penetrating wounds in the body. After being pushed to close-up shots, autopsy personnel use probes to probe the depth and penetration of the wounds.

Indicate

c) Skull fracture shooting, the scalp should be peeled off to expose the fracture site. After cleaning, multi-angle, comprehensive and coherent shooting;

d) intracranial hemorrhage should be taken in situ, then the brain is removed and placed on a contrasting substrate for shooting;

e) Skull base fracture shooting. If using artificial light source, please pay attention to adjusting the camera distance and light angle.

To avoid shadows;

f) When photographing blood, wounds or other injuries in the chest, abdomen, and pelvis, the camera should generally be viewed from a top angle, and the sternum and other people should be avoided.

For the blocking of industrial light sources, the distance between the camera body and the photographic surface should be adjusted, and small angle lighting should be used. Wound or damage imaging on the arc surface in the three chambers, can use manual focusing;

g) Close-up devices should be used for small features such as coronary artery occlusion profiles.

8.2.4 Specific requirements and imaging methods for organ inspection imaging.

a) Tissues or organs should be photographed in situ before harvesting to reflect their original condition;

b) After picking, they should be cleaned, and the water stains on the surface should be dipped and placed one by one on a contrasting substrate.

Photo. Can use push or pull to fully reflect its size, shape and surface characteristics;

c) Shooting of small features such as bleeding points (spots) on the organ, you can use a close-up device to push to close-up shots;

d) The hyoid and thyroid cartilage fractures can be photographed using a close-up device and pushed to a close-up shot. If the accompanying muscle tissue is bleeding, it should be taken first Then all the muscles were peeled to reveal the bone and fracture site, and then pushed to a close-up lens to shoot the condition of the fracture point.
