DJVU vs JP2 comparison

File name	File type	File size and link to image	Comment
Cell	Original CR2	13Mb	The original camera file. One of the hanging pans has concentric rings etched into it.
Cell	PNM	30Mb	An uncompressed file for later conversions. Note the detail in concentric circles in the hanging pan.
Cell	DjVu	1.4Mb	Converted with c44 -decibel 47 -slice 2,12,72,83,93,103 -bpp 0.001,0.01,0.02,0.10,0.25,0.5,1
Cell	JP2	30Mb	Converted with pamtojpeg2k A very small file just to see what happens with a very small JP2
Cell	JP2	1.4Mb	Converted with pamtojpeg2k At the same filesize as the DjVu, JP2 has a visible loss of quality in the concentric circles
Cell	JP2	30Mb	Even at double the file size of DjVu, there is loss of detail where the plant leaf overlies the concentric circles
Cell	JP2	30Mb	An even larger JP2 file still showing noise in the rim of the hanging pan
Cell	JP2	30Mb	A JP2 of this file size is not useful for saving on storage space
