Goldie? Isn't that 590nm swapped, or is it something higher swapped?
Isn't "Supper Blue" BG3 with the correct WB? Isn't that somewhat the same as 590nm swapped, except without swapping?

David, by the way, depending on the size you want, there is Schott KG3 2mm thick available on eBay.
This one will fit in a 72mm ring, so if you get a 52mm to 72mm step-up ring you can drop it in that, and hold it in with a 72mm retaining ring or with another 72mm ring to give it more front thread if needed.

Added: Here is some Schott KG3 while they last:

If you want one smaller, just search for KG3 filter, but pay attention to thickness, I recommend you get 2mm thick.

Morning shot. I like how this works. :)
Once again, Lee Scuba Blue #729 + Schott KG3 2mm stacked, in camera custom white balance.

Live View shot. "What you see is what you get". Just in case you thought maybe I was tampering with the image in post... Nope. :)
That was a lot of red spray paint though! ;)

That last one looks great for a SOOC emulation. Should be interesting to play around with when everything is in full bloom.

If you look off to the far right, you will see some daffodils in bloom, yellow stays yellow, red stays red, as expected with this type of EIR/Aerochrome simulation.
Doesn't bother me, this works for me.
However, I think probably the best emulation of EIR/Aerochrome is the process you are using. I use the H.H. Photoshop action, same idea, but maybe yours is better.
But this SOOC filter stack is really fun and nice to use.

Thank you. :)

I am all out of red paint now though.

They mix the International Orange paint used for the Golden Gate Bridge also! :D

That bucket would be crazy. Looks larger than the moon. Once all the paint is out you could populate the sides. The gravity on the oceans would really cause issues. Not withstanding the paint on the oceans.

Cadmium, were you earlier saying all I would need to do is a custom WB using a BG3 like filter and I would get incamera goldie like IR images? I don't have a Bg3, but I do have similar filters. I will have to try that.
Also on ebay I mostly see GRB3 glass, Chinese equivalent to Kg3. Even the one you link to says its from china. With the word similar to in the description. Did you test this glass or genuine from Scott Kg3?

Well, first of all I don't know which filter is "Goldie", is that 590nm swapped? I have heard the term for many years, but was confused if it was 590nm or possibly 665nm?
Regardless, the closest non-swapped filter that I can think of might be BG3.
LifePixel has what they call 'Supper Blue', which many people came to agree was BG3.
There are other blue glass filters that I have seen used to do the same look, basically very strong yellow foliage and very strong blue sky.
47, 47A, 47B... all slightly different, but may work close to the same idea.
There may be many other dual profile (dual band) filters or stacks that would take you closer to the Goldie look you have in mind.
It becomes a situation similar to the B-410 which is close to red, but more orange for me, but then I have not white balanced that filter in camera so far,
I may find that it will white balance in my Nikon camera (like the 729 stack does), and it may look redder than it does when I use software to WB it from RAW.

I am not familiar with RGB3 glass.

I am using Schott KG3 2mm. I didn't notice that the eBay link I posted was Schott or from China, just that it said KG3, sorry. Let me take a look again now.
Here you go, how does this one look, I am pretty sure this one is Schott KG3. 50mm x 50mm x 2mm it looks like, they have a few of them.

I learned the about the Goldie term when exploring possible methods and filters for IR-photography.
I have only seen 590nm swapped for that style.

Just as EIR filtering is IR + (VIS - Blue)
Goldie filtering is IR + Red

Yes,
Sorry I wasn't more clear. The 590nm or using either a #24 or #25 filter and channel swapping to get the golden foliage look. Called a goldie filter.
I have the #47, bg12, b370 filters. I will have to see if that WB to a similar image.

From Andrea's K5 filter test series I remembered the Bge being really yellow and not too much golden. But I will have to try and see what I can get. The lee swatch book has pretty much every blue you can imagine.

OK, Goldie = 590nm swapped then. Good.
By "EIR filtering" do you mean pre ordered 'IR Chrome', or #729+KG3 2mm, or both? ;)
Anything in the 600nm to 700nm range of longpass filters would be IR+Red, right?

K5 filters?? Bge??? No idea... Can't find those, link?

B-370, try that, it is very close to BG3.

Guessing here, maybe "K5" meant a camera brand/model? And Bge meant BG3?
See these links for BG3 look:

My statements about EIR filtering and Goldie filtering were intended as very generalised descriptions.


The EIR filtering was for the real analog film.
Kodak recommended the Tiffen 12 filter for their film => no Blue.

It would also would work for a proper digital simulation with the Tiifen12 action.
It is likely that Schott OG530 and OG550 and Nikon O56 will work well too, instead of Tiffen 12.

Sorry Cadmium,
But your chain made me smile. Yes I was referring to the Pentax k5 camera filter series tests with the Bg3. I mostly type on my phone and e is below the 3. Sometimes, I miss the numbers and hit the letters.

One problem with the 729 filter is that it is dark, works good outside, but indoor lighting needs higher ISO, etc..

Lower lighting conditions are more of a challenge for the 729 filter.
These are SOOC, and I didn't make a new custom white balance, I am using the same CWB I made for the sunny outdoor shots.

Outside, overcast and rain. You can't see the rain in this pic, but the 'mistiness' is the rain.
Here I used ISO 400, f/11, Exposure was 1/25s (hand held).

Grocery store produce. Guess which lighting contains infrared? ;)
Here I used ISO 1600, f/11, 1/5s (hand held).
