Does APG's LZW compression work well?

by j_h_w » Tue Jun 02, 2015 6:40 pm

I am working with APG 64bits 4.0.1 on Win7.
My input files are 16bit TIFs (Sony *.ARW, converted by Adobe Camera Raw).
My APG rendering produces 8bit TIF with LZW compression.
A typical output file size is 215 MB. Fine, no artifacts or whatsoever.
But, when I open this file in CS6 and store it again as 8bit TIF with LZW, it takes only 135 MB.
That is a big difference in size. How does it come?
