samples for comparison

This is an attempt to make an alternate repository not limited to 8bpc, hence catering to 10bpc screens or better.
At present, I could not exceed 13MB creating a bpg from a 16-bit TIFF DP1M picture (via lossless 16bpc png) using a bpg encoder :

Tools : http://bellard.org/bpg/


These are various sizes obtained with different colot depths and compression ; they could be seen with decoders linked in the above site. 
    720,308 bytes  DP1M3502_8bpcQ28_ycbcr.bpg  default quality
 7,294,420  bytes DP1M3502_12bpcQ0_bt709.bpg  
 7,944,021  bytes DP1M3502_8bpcQ0_bt2020_x265.bpg   
13,051,134 bytes DP1M3502_12bpcQ0_bt2020_lossless.bpg

and these are the sizes of the 16bpc sources :
56,536,164 bytes DP1M3502.X3F
88,564,104 bytes DP1M3502.tif
70,688,608 bytes DP1M3502.png



If this is suitable, I might populate these sites later, according to the category they fall under :
