Hi-Con IR (IR imagesetting film)

[MCB18]

I’m actually pretty stoked about this not gonna lie. Wish I had a LF camera to expose it as sheets, I can get 11x14 sheets from this roll and I bet it would look absolutely amazing

Developed a test strip in Rodinol 1+50 for 10 minutes, the results at EI 3 are basically identical to the D76 results.

I am going to make a couple of rolls of this stuff that I can take out and about tomorrow and get some pictures in the field. See if this nice behavior continues when it’s not in a somewhat controlled environment.

Still don’t have proper scans, but using data from a similar film I made this chart showing the spectral sensitivity of the film. I was assuming “log exposure” and “relative speed” are the same thing, but honestly idk.

I finally scanned the visible light and IR negatives I took like a month ago, properly this time. And I haven’t quite finished processing them, but I think I might’ve discovered something absolutely wild. One of the pictures didn’t turn out how I expected it to. I took a picture of a tree, and it should be pretty dark. But it’s not, it’s almost white… I think this film is so insensitive to green light that I’m getting wood effect without an IR filter. I didn’t even realize that that was possible. I will post the finished scans when I’m done with them.

Yeah I know the scans aren’t the greatest, and I definitely missed focus when shooting some of those shots, but here are the scans. And yes I am aware that there was a hair in my film gate when shooting, I wanted to clone it out but I couldn’t figure out how.

All were developed in HC-110 F for 9 minutes. The last one used a 720nm filter.













Notice in the 4th picture that the tree is very bright where the sun hits it despite the other green objects shown (the color chart in the first picture and the back car in the 3rd picture) being extremely dark. As said earlier, I suspect that this is the Wood effect, despite no filter being used.

You should probably post a colour photo alongside the colour chart, for easier reference...

I'm not so sure; I think this is mostly because we're looking at a precipitously steep curve.

Just to make it easier...
