I know it is a pain but colleagues and friends of mine have seem the pictures, like the quality and complain if I reduce the file size. I do down size for my deviant art page the HDR picture 13828 tonemapped is a compressed 14-bit colour picture of 7378x4924, file size 25.9MB jpg file, but the original tif file was 207MB.
A boring picture which would have no fans on your site.
The nominal size of files you produce are big enough, sorry Rick I did not mean to spark such emotion, but I can remember when my camera had a 256MB compact flash card which would take me weeks to fill, now I am using 256GB and 128GB compact flash cards which last one session. The down side is the standard FD display will not allow the pictures to be view in the optimum way, you get moire fringing. Sorry I am going on and yu have more important things on your mind.
Your doing a great job and I hope you keep it up.
