Under development (starting 9-May-2008).  More to come... this gallery will be devoted to a self modified P&S camera with removal of the hot mirror and replacement of clear glass and then combined with a Hoya R72 IR Filter.  Eventually I will post more images and an instruction set on how this camera was modified.  If I get ambitious I will probably replace the clear glass with an IR pass filter.  If anyone is interested, this is a old 2.0MP Sony DSC-P51 -- there is no provision for manual exposure so it needs to be tricked to a high f-stop using one of the scene modes.  If you have a comment or question about IR, please put a note in the guestbook or leave a comment and I will get back to you (usually via pbase-mail or email)...

Update: June-2008 – I have replaced the clear glass with a piece of IR Pass Filter which was hand cut down to size from 2" x 2" sheet.  Stock thickness of this filter was close (1.5mm) to original hot mirror (1.7mm) and differection index was similar.  The camera still seems to autofocus within acceptable parameters.  This IR filter is thermoset resin, easy to cut and very inexpensive.  I paid less than $7 usd for it + shipping.  edmundoptics.com Item #43953.  I intend to publish detailed conversion instructions, but general laziness is preventing me from doing so at current time.  Hopefully soon!  Current favorite setting is EV +1, WB Tungsten, focus forced to 7M or Infinity.  This camera is so old it does not have Custom WB or even a histogram readout.  First image with this modification starts at #01029.
