Nikon "Coolpix P1000" - 125x Optical Zoom!

wrote: Yeah, but...what do you think of the P1000? The ultimate private detective camera. actually that would be an infrared camera. Why? because infrared light is not visible to humans, so a detective could take photos in the dark, lit by infrared flash, and nobody would notice anything unusual. another use is forensics to detect forgeries or other anomalies. https://kolarivision.com/articles/forensics/ True infrared might not show sufficient details for meaningful identification. Images taken from a long distance would. not necessarily. the above example clearly shows what was underneath smeared ink as well as a bogus check. there are many other examples, including cover up paint to hide damage, however, nothing is guaranteed in all situations. I suspect you were conflating near IR with true IR. i wasn't conflating anything. BTW you just reminded me that Apple used to sell IR lenses in its stores, but recently stopped. i want to see if they are available online. for the iphone? if they did, it was a third party product. |

Forensic IR, and/or UV photography is a different animal to IR photography at the hobbyist level. IR, and UV photography is use for collection of latent evidence not visible to the naked eye. Stuff such as document examination, latent footwear impressions, fingerprints, body fluids including blood, pattern injuries such as bitemarks. The tools and lighting techniques include, but are not limited to various filter, and light source options, reflective IR, reflective UV, and IR fluorescence. Cameras converted for forensic use are not generally available to non-law enforcement, even from B&H, or Lifepixel. https://www.lifepixel.com/infrared-p...ications-uses- forensics https://www.lifepixel.com/uv-ir-forensics http://www.evidencemagazine.com/inde...sk=view&id=106 http://www.evidencemagazine.com/inde...sk=view&id=228 0 https://kolarivision.com/articles/forensics/ -- Regards, Savageduck |

Note; I wrote, “...are not generally available to non law enforcement”. That does not mean that there is no way to obtain cameras converted for forensic IR/UV work. The big question is what that non-law enforcement individual would do with such a conversion. -- Regards, Savageduck |

Just about the only thing I can think of which meets that definition is the old Minox, and that doesn’t have a 3,000mm lens. https://en.wikipedia.org/wiki/Minox -- Regards, Savageduck |

Yeah, but...what do you think of the P1000? John I will try it when it's available, and buy it if there is not too much noise, or shutter lag. That thing's going to need some extraordinary IS. Or a tripod. Or high ISO capability, and extraordinary tracking ability. I suspect it will not be suitable for me, but I will give it a fair try. Without a tripod (or a pretty steady support, for a stationary target) it is going to be very difficult to use at full zoom. |
