hey guys,
I've been using photomatix trial for the last month and have loved the results but it has now ended and a watermark is put ontop of the hdr image now

i don't really want to buy any expensive software as i do have CS4 but the automated HDR thing isn't really giving me the same results.
so the question is, how do i make the images on CS4 look the same as from photomatix or is there some free-ware that I can download.
Any suggestions would be very welcome as I am desperate to get my HDR sunset finished.
Thank you a lot,
Jan
