Hi all,

I know that the nx_cs.adj file has been discussed here a while last year (and before), but in other context. I own NX500, which I occasionally use for timelapsing of the night sky (you can find some of my astro-timelapses here: https://www.setvak.cz/timelapse/2019.html). The time has come to map out the hot pixels; it is possible, the procedure is described in the NX500 Service Manual, but requires the nx_cs.adj file, which I don't have. Is this some standard file to launch the service menu, or does its content change depending on what you need to perform with the camera? Also, the instructions refer to an "Adjustment folder" which needs to be on the same card as the nx_cs.adj file. Is this just an empty folder where the camera stores some info from the procedure, or does this file need to contain something specific?

Thank you for any advice on this.

I've seen this referenced in the service manual as well but as far as I know that file has never been publically available or by any forum member. However, you can try setting the date on your camera over and over. I believe it will remap automatically on a schedule, so setting the date in the future over and over and then turning the camera on and off may have some effect.

I can't remember exactly. I had an nx1 some years ago that had a couple hot pixels. There isn't any documentation that I could find for Samsung cameras, so I tried a little of everything. I changed date, took photos with the body cap only, etc. I wish I could remember more but I don't. Some cameras remap when taking photos of black with the body cap on. Some do it on a schedule.
