Infrared Photography And "precious Resin"

Partially answering my own question here, here is a link I just found regarding the science and technique behind this:

Oh, and another introductory vid I found:

The black Pelikan M400 and M405 appear to have quite a bit of fluid inside. Was this ink? If so, it seems that kind of ink is also IR transparent; I would be very interested to know what ink it is. If not (you just store those pens with water in them), never mind ... .

looks great!

... euh, but what does it mean? What's your interpretation of these images?

outstanding :thumbup:

Pens are like watches , once you start a collection, you can hardly go back. And pens like all fine luxury items do improve with time

This is interesting. It would be nice if someone would post an explanation of why and why not (e.g. with some of the example photos) this works or not. Is it something about the materials used in the pens (plastic types)? How was the lighting done? Was there an IR light source used when the IR photos were taken?

I'm not proficient in IR photography, but I know some of the fundamentals. Are the internals of the pens visible with IR photography due to the difference in materials, or due to the difference in temperature, or a mixture of both? Again, maybe the OP can clarify a bit more.

BTW: there is an inexpensive IR camera module available for the ubiquitous Raspberry Pi computer (~$35 USD) called the "NoIR" (looks like the name is a take-off of the French word noir for black) that has the IR filter removed so it can see in the IR spectrum. The Raspberry Pi NoIR camera module costs an additional ~$30 USD. There have been some impressive results with IR photography done with the Raspberry Pi NoIR camera. Google knows where you can find the stuff.

One more thought: I wonder if the pens photographed with an IR capable camera will show more detail or even more detail regarding ink-flow if the pens when empty are cooled like in your refrigerator then filled with warm water (or ink), then IR photographed. Before and after examples would be nice if someone wants to try this.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
