The Jeffrey MacDonald Case

Debunking FrmrCSI’s alleged “analysis” of the bloody footprints

 

JPEG utlizes “lossy” data compression, resulting in loss of pixel information and degradation
 

This is a JPEG scan of text.  The same sort of degradation happens in JPEGs of photos, but that degradation is often not discernible to the naked eye because the eye is too busy processing the surrounding information.
 

This link shows a crime scene photo on The Jeffrey MacDonald Information Site.  JPEGs are often used on websites because the “lossy” format results in reduced file size and therefore a faster display on the visitor’s screen.  To examine the degradation more closely, four cropped and magnified sections of the crime scene photo are shown below.  Note the “spotty” effect in various areas, the “halo” effect around some areas where dark meets light, and generally the same sort of degradation as appears in the image above:
