You would be taking long medium and short range shots of category 1 and 2 images, after doing so you would document the date and time that the photo was taken.

you will need to fill the image with the piece of evidence or area of interest so it can be properly analysed and compared.  

the photo taken needs to be at a 90 degree angle because the scale ruler needs to be next to the object, if the photo is not at an 90 degree angle the image becomes distorted and unusable.]]> 2019-05-24 09:02:55 UTC https://padlet.com/awilson138/896y5rae6nnj/wish/363210684 Equipment https://padlet.com/awilson138/896y5rae6nnj/wish/363211380
3 types of cameras:
Metric: Cannot focus lens when taking a photo which means they have limited distance in which they can take photos.  
Stereometric: This camera can be used to produce 3D photographs by taking two different photos from different angles 
Normal: All calibration for the camera is calculated. 

Shadows are eliminated by using secondary lights so there are as few shadows as possible

Different angles will be used to take different photos. A long photo will be used to take photos to get the whole crime scene. A medium photo will be used for a reference point for the evidence. A short range shot will be used to get a close angle on the crime scene. 
An ABFO scale will be used to measure the evidence and give it a reference point.
A photo log is used to record each photo taken, a description of the photo and what settings you used much be noted down.
A photo identifier tells you what crime scene you are at]]> 2019-05-24 09:07:05 UTC https://padlet.com/awilson138/896y5rae6nnj/wish/363211664 Photo identifier https://padlet.com/awilson138/896y5rae6nnj/wish/363212079 After the photo has been taken, you need to write down the case number, time and date, location and address, and the photograph ]]> 2019-05-24 09:09:06 UTC https://padlet.com/awilson138/896y5rae6nnj/wish/363212079 Photo memo form https://padlet.com/awilson138/896y5rae6nnj/wish/363212945 This is important for film cameras. It can record photographic variables, for example camera type, lens focal length, aperture, shutter speed, iso settings, whether the flash was used or not focal length - these are all done automatically with digital cameras]]> 2019-05-24 09:12:55 UTC https://padlet.com/awilson138/896y5rae6nnj/wish/363212945 Labelling https://padlet.com/awilson138/896y5rae6nnj/wish/363214553 A scale is provided from an image taken as indication as the particular size of a piece of evidence. This provides information about the conditions of which the image was taken under, these can be presented in court to make the image more trustworthy, providing an accurate representation of the scene. A labelled scale uses the same elements of a photo identifier along with additional information depending on the sops. ]]> 2019-05-24 09:20:17 UTC https://padlet.com/awilson138/896y5rae6nnj/wish/363214553 The purpose of crime scene photography is to document what is the reand where it is in relationship to the scene, whether it is obviously connected to the crime or not. https://padlet.com/awilson138/896y5rae6nnj/wish/363215211 2019-05-24 09:23:45 UTC https://padlet.com/awilson138/896y5rae6nnj/wish/363215211 Indoor forensic photography procedure https://padlet.com/awilson138/896y5rae6nnj/wish/363215847 2019-05-24 09:26:21 UTC https://padlet.com/awilson138/896y5rae6nnj/wish/363215847 Weather can affect fragile evidence, therefore protection of crucial evidence is very important. It's usually protected by portable shelter e.g. tent or canopy. https://padlet.com/awilson138/896y5rae6nnj/wish/363216003 Investigators must wear there PEE kit before entering the crime scene, then after they must fill in an entre log and being taking images.The images taken at 90 degrees angle and short, medium and long range images. Any images not presnted in court must be secured on a photolog. This is to ensure the images are safe and not tmapered woth so the defense team dont have anyhting against them, for missin images.

- distracting foreground elements: tilt the camera up

- shadow control: eliminate sun shadows and own shadows]]> 2019-05-24 09:28:53 UTC https://padlet.com/awilson138/896y5rae6nnj/wish/363216406 awilson138 https://padlet.com/awilson138/896y5rae6nnj/wish/363216442 Photography techniques such as lighting and aperture can help visualise important evidence. ]]> 2019-05-24 09:29:01 UTC https://padlet.com/awilson138/896y5rae6nnj/wish/363216442 awilson138 https://padlet.com/awilson138/896y5rae6nnj/wish/363216467 F/stop selection

A long or wide-angle view, sometimes referred to as an establishing shot.

A medium or midrange view which focuses on particular objects, areas or evidence items.

A close-up view that clearly shows what the item is, its condition and its position at the scene.

  • The majority of evidence photography is now done using digital cameras and equipment. All photographs taken are saved as originally captured, entered into evidence inventory and tracked.
  • When images are presented, they must be clearly identified as a working and/or enhanced version. The original camera sequential numbering system should be retained to show that images are in order and none have been removed. The working images should not be renamed until identified or selected for use, and original files should not be renamed at all.
