I've discussed with teerex as mod of this forum for this thread.This thread is a discussion thread and
it'll start from me as Thread Starter. My goal as the Thread starter is i wanna make a IR open source,
together we explore the Infrared Photography..

Introduction

As u know, infrared photography is a false colour. In digital, Digital cameras have a special infrared-blocking
filter in front of the light-sensitive CCD?CMOS array(called as hot mirror), as the IR light degrades the
visible-light color rendition (the CCD/CMOS itself reacts to wavelengths up to 1000 nanometers and even longer).
The question is how much of infrared will the filter let through, of course it's depend on the filter that we use
as the replacement for the hot mirror or we put in front of the lens and it'll affect the tone.
Photographs in infrared show quite unusual tonality, different than that to which we are used, and this may make
them esthetically pleasing, at least in many cases. Which, of course, is a matter of taste.

Consept of IR

as you can see, there are 3 diff type of rays (i'll skip another rays like cosmic/gamma/microwaves/centimeter/ultra/shortwave/broadcast radio ect)
UV that has a wavelength below 400nm n VIS which has a wave length more than 400nm until 600 something.
and the question is, how if we want to let the sensor of our digital camera catch the infrared ray without any problem?
coz we know that, every digital camera have a hot mirror that :
• Reflect IR
• Transmit VIS
ok, some will say, use infrared filter like Hoya R72 or Cokin 007 (long-pass filter).It's correct, but you'll face the consecuences..
speed will drop n lack of variety tone. The better hot mirror will make the speed more drop.
my suggestion..operate ur cam
there are several thread about this.
important : find the meaning n the consept of longpass filter

BREAK THE RULE
--
I start my IR experiment since a year ago and i found something interested, will it be possible to mix the infrared
with VIS?or UV? coz i feel a bit dissapointed with full infrared, lack of colour. Break the rule, i keep on my mind that
infrared photography isn't only about infrared ray.
why?
1. Taste, some people prefer still love normal cam and most of them do not like iR coz zombie skintone if u shoot human skin
2. The real full iR is Black n white colour, GOD doesn't make a world in BW colour..make it colorful
how?
it'll start from me as Thread Starter. My goal as the Thread starter is i wanna make a IR open source,
