The Jeffrey MacDonald Case

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

 

The three pictures FrmrCSI used in his “analysis”

 

1. Cropped section from original crime scene photo


 

2. Cropped section from original crime scene photo, but image processing and “enhancement” (apparently consisting only of changing the contrast, altering color balance and resizing) done by FrmrCSI has resulted in degradation of quality, interpolation and anti-aliasing, and the loss of the correct aspect ratio (foot is now considerably longer than it should be).


 

3. A copy of the original crime scene photo on The Jeffrey MacDonald Information Site

 

Unfortunately, FrmrCSI’s image (directly above) has less pixel information in it than the original JPEG he started with. This is apparently due to his having again having saved this final image as a JPEG, which removed even more information from the original JPEG.  JPEG uses “lossy” data compression, meaning a loss of pixel information occurs when an image is saved in that format.  The original JPEG on Christina’s website had already lost an enormous amount of pixel information when the original BMP scan was resized and saved as a JPEG, and when FrmrCSI saved that image again as a JPEG, even more data was lost.

The proof of this loss of data is evident when the file sizes are compared.  The original crime scene photo on Christina’s website is 18,622 bytes in size, but FrmrCSI’s image is only 18,172 bytes.
