I discovered something surprising

As you might be already aware of, I've been into researching how to create a full spectrum with great UV response. To do so, I did much research into each individual spectrum of light and how camera sensors respond to them. I've been wondering if I could use a GoPro to record UV video at night using onboard Full Spectrum LEDs (Yes, for paranormal research, but possibly other applications as well). During my research, I realized something surprising: there's a cheaper way to achieve photos or video of each individual spectrum of light at the same time, as well as each one at the same time. Instead of purchasing an Infrared filter (approximate price=$30), IR/UV Blocking Filter (Also known as Hot Mirror, can be found in most cameras, ones that aren't modified [cost=~$70]), one can, paradoxically, spend less by purchasing more filters and perhaps possibly get the same range of effects that might be identical: First of all, Try and find the diameter of your lens' filter thread first. For example, if it's 50mm, look for 50mm filters. Next, try and get access to what's known as a ZBW2 filter (cost is relatively low) that can filter out only the visible spectrum, and have it become a 50mm thread around. Next, get a UV-block filter to block out only the UV spectrum (once again, 50mm diameter) which could easily be the cheapest of all filters. Last but not least, and this can be difficult to find, find a specialized Hot Mirror, one that can filter out only the IR Spectrum- or, instead (I'm not sure which option is more affordable) get an IR pass filter. Sorry for the confusion. Let me explain: A UV-Block combined w/a Hot Mirror (IR-only cut) can get you to normal photos: at the same time, if you use the Hot Mirror in conjunction with a ZWB2, you should, at least in theory, get UV-Only photos. Keep in mind, this has to do if the camera is modified to see Full Spectrum, ideally with a specialized lens that can transmit each of the individual spectrums of light (UV,VIS,IR) precisely without causing any optical distortions or anything else optically "incorrect".

The Thing less talked about...

When I see strangers that look nice, and I know that this was the first and last time I’d see them, I feel like writing my story about my different state of consciousness that is on the other side of the emotional spectrum, not the positive one, and I want to enter into a positive state of consciousness, different from the usual ones. The courage of my mind is not merely enough to proceed any further with anything at all, however. And I feel like I have died and I just have the false perception of still living the same life. Oh wonder, how things will work out, not being aware of just how bad things are. And yet you keep trying to push me, force me, to undergo life as though it’s a positive experience despite my inner despairities. It's something that only gets worse with time. After all, shouldn’t life be about pleasure, not pain, and/or perhaps one shouldn’t obsess over pain but over pleasure, and be addicted instead to pleasure rather than pain...

My future vision of this week...

I have a vision of this week, most likely on Thursday: "The truth about happens on Thursday, March 21, 2019, will be unveiled to the world news, and the news will report on it using a negative connotation. Violence will ensue Friday night, exactly two days after the start of astronomical spring. And the first day of the season, the 20th of March, a strange occurrence in the United States, and a controversy. But out of all that's been on my mind, it's a vision that is most surprising...one that describes something, a dark but quick moving object, descending down to Earth" It's that time of year, again, when strange stuff starts to happen, and I honestly wish that it didn't, that instead more peaceful stuff could happen. I'm not one to say stuff with certainty each time, though, I'm just gathering data, either that or using intuition
