Thanks! I'll check those videos out later in the day.

Still looking for a good way to strip the black antihal off of Aviphot without also removing the blue sensitizer

I tried this, constant agitation:
1) fresh dH2O for 5s
2) fresh dH2O 5s
3) 100% IPA bath for 60s (can be reused) - stops the removal immediately at the archived state and makes film dry super fast. Like 5min just by hanging.

This removes just the black AH layer. Examples that I got: https://www.flickr.com/search/?user...desc&view_all=1&tags=AntihalationLayerRemoval, including those where also tue blue layer started to come off.

Make sure to let all of us here know how well it works. At least one person is interested in how well it works. Me!

Thanks! I'll develop them in a few days. Took 2 rolls of 120 to make 4 6x9s...

J & C is still in business? Just googled them and the answer is no. I suspect any IR film from them is getting pretty old now.

My first experiment went okay, but I'll definitely use my bigger, steadier tripod next time. It's hard to not jostle the camera when using push-on filters. Tilt/shift jostling isn't as bad as rotation. Also not the easiest to do the mental math for 3 different filter exposures without the occasional mess-up.

How saturated the resulting image is varies based on how saturated you colorize each channel as well as the constrast curves and lightness values chosen on that step. I went with less saturated for this one as it's easy for rainbow effects to look too gaudy. Old uncoated lenses also don't look their best with too much artificial contrast.

Fall hasn't hit yet here, all the leaves in this photo are green in real life. I try to pick something like old gray wood or a tree trunk as a gray point to color balance the image as well as register the frames.

I like how with trichromes movement becomes the subject very strongly because it literally gets highlighted with a rainbow.

It would be cool to have some type of filter holder that you could slide quickly between the 3 filters. These shots were taking quite a few minutes, when I see trichromes made by Prokudin-Gorsky I can tell from the movement of people that it couldn't have taken him more than 10 seconds for all the exposures because he had a sliding device on his camera.
