Hi CindyNow I get it, after looking at the man's shirt. It looks just like a photo from my former M8 without the cut IR filter on the lens.
So, if you put a cut IR filter on the lens, you can use it like a regular camera? Then if you put a 665nm filter on the lens, it can be false color?
Is there any downside to doing this to a camera?
Yes if you put a hot mirror filter (which is an UV / IR cut filter) on the front of the lens, then yes it is "back to normal" visible light.
And yes - on a full spectrum camera you can put the IR cut filter of your choice 580 (I think there is one in the 500nm range)- 650 - 720 - 820 etc. The only downside would be; you need to get step up rings (assuming you get a 77mm - which I advise) and also remember to take both the filter and correct step up ring.
I have been told that there are advantages (better detail) to the having the hot mirror on the lens as opposed to the sensor, but I am not that technical.
Also - I have been told for B&W conversion - shooting full spectrum gives you a more detailed image than a camera with a hot mirror.
Here are two hot mirrors that I know of
B+W 77mm UV/IR Cut 486M MRC Filter 66-031976 B&H Photo Video
Hot Mirror UVIR Cut Filter | Kolari Vision Infrared Conversion Service and IR Photography
I have both and like the Kolari better - I got one from them when they converted my Fuji X-Pro 1
Thanks
Phil
