I have an old Nikon Coolpix 950 that I intend to remove IR filter from. It has a serial port!

However I had to keep the JPGs to around 1500px wide or the whole thing gave errors and then crashed. Having seen how much RAM and diskswap this chain takes on my virtual Debian laptop it isn't surprising. Even if you use JPGs the chain expands these to the pfs stream and then the hdr images and these files are big.<br /><br />If you use enfuse you can't make HDR from that image. A lot quicker too!Anonymoushttps://www.blogger.com/profile/16096091258904878287noreply@blogger.com
