Hiya... Whipped up a couple of Aerochrome filters. With an in-camera custom white balance off half foliage, half sky i get desired results out of the camera.
Heres some examples and some visual data showing the cutoff that occurs.

The first spectragram is the cameras regular spectral light collection with no filter... The light used put out no uv, but alot of infrared.

The second is the cutoff from filter#1 and the third is filter#2

Filter#1 is one layer of deep cyan gel sheet with some thickness to it.

Filter#2 is two layers of a light cyan and of a thinner material.

I work alot so havent been able to get alot of testing photos... But what ive gotten isnt just straight red foliage.

What are your thoughts?

Artistically, your second sample image has a certain old-school coloration about it which is interesting. I do not know to what extent that is your "desired result."

"Desired result" is as close to the real thing as inhumanly possible.

Other factors seem to interfere.... Less sun gives a richer red, lots of sun seems to bring out yellows and such.

But i thought id show someone

If by the 'real thing" you mean the old Kodak films, I suggest you check out the examples here--there is more diversity of look there than many realize. Some of this is due to variations in film scanning, some to film development (E-6 vs AR-5;) more of the variation is due to the various filters preferred by photographers. So you may be aiming for a rather fuzzy target! Perhaps you mean a particular subset of images such as these?
