 Yo, what up welcome back to another episode where I felt cute, but I don't know might delete later Well, we're in for quite a unique one today gang long story short. I found a point zero six ISO film That's right point zero six not six not sixty Not sixty nine point zero six ISO and to make matters worse. It's almost 20 years expired, but we'll get into that later It's called Kodak rapid process copy film and as legend has it its sole purpose was for copying radiographs Otherwise known as x-rays to slides with such a low ISO It took on average about 12 to 20 seconds to copy a radiograph to this film at f4 So because this was meant to be mounted in slides, this is a black-and-white positive film Probably the coolest part though is that this film blew itself Yeah It's blue probably because radiologic technologists are big fans of the movie avatar Either that or they were accustomed to seeing x-rays with a blue backing and Kodak just decided to keep in continuity with that Needless to say though It's pretty cool to develop the film is recommended you use DK50 developer But that ain't around anymore. So a few cases online suggested using Kodak HC 110. I Don't know anything about developing so I hit up my day one film homie Caleb for answers So I grabbed all the necessary chemicals and headed down to master Caleb's dojo Caleb was brave foolish enough to take this challenge head-on. So why don't you go follow his YouTube channel bad flashes? Once they were developed and scanned the images came out quite flat and blue But when they were converted to black-and-white you definitely needed to add some contrast to really like see the image Anyway, let's rewind a bit and get to shooting since this film as well as myself have been described as brutally slow I figured I would need a tripod even though I've mastered the art of holding a camera perfectly still for hours on end Thus Caleb and I cruised out to the boo. That's what we locals call Englewood Honestly all I was hoping for was to have some shots turn out and not waste an entire roll of them Damn, bro. Oh my god. That is literally the coolest Yeah, I'm gonna be honest with you 95% of these shots did not turn out at all I guess that happens with film sometimes It's a bummer, but sometimes you have to fail to learn which is an excuse I used a lot in middle school when I'd have to bring my tests home to show my mom So there we were shooting a bunch of fire shots to light up our Instagrams But I guess it doesn't matter now. So let's skip ahead a little bit in time to the shots that actually kind of did turn out We got a really colorful sunset that evening, which was perfect because I was shooting black and white Shooting directly into the Sun with a telephoto lens still gave me an exposure time of one second with this film so What went wrong here? Honestly, it could be a number of things first off I shot this film at point zero two ISO instead of point zero six ISO Which made things a little more complicated the reason I shot at point zero two ISO is because this film expired in February 2003 now, I don't know what you were doing in 2003 But me I was watching my favorite movie Kangaroo Jack on repeat and I didn't really have time to think about really low ISO film So since 2003 was 17 years ago I used the 10-year one-stop rule which basically is if it's been expired for a decade add one stop a light Well, we should be adding two stops of light because 17 years is definitely closer to 20 years I don't really think that's how the law sees it and I don't think it'd fly in court But yeah, I ended up doing the math and added one point seven five stops of light which gave us an ISO of point zero two It could be that even though this film expired 17 years ago It was stored properly in a freezer all those years and thus did not deteriorate in line with the 10-year one-stop rule In which case all of my shots would have been overexposed by one and three-quarters of a stop Which actually would make a little bit of sense because most of the unusable shots were either blown out blank or Had little to no detail in them But I don't know I wouldn't necessarily think that one and three-quarters of stop of overexposure would blow out every shot Especially when every shot was metered the same way and a couple shots did turn out So what I think it was even though I triple checked it was that the workaround that I did for my light meter was Somehow wrong light meters don't go down to point zero two ISO because why the fuck should they? So this is where it gets a little bit complicated because math sucks And I got the shit beaten out of me a lot in high school not because I was a math nerd though I just got beaten up a lot Since the ISO that we're cruising with is point zero two. That's roughly 12 and three-quarter stops under ISO 25 Luckily the light meter on my phone goes down to ISO one which is roughly five stops under ISO 25 So that means we need to go another seven and three-quarter stops down from there So basically what I did was that even though I was gonna be shooting wide open at f2 I told the light meter on my phone that I was gonna be shooting at an f-stop That was seven and three-quarter stops darker than what I was actually shooting at that way It read the scene as if I was shooting a point zero two ISO So f2 goes down one stop to f2.8 Which then goes one stop down to f4 etc etc all the way down to f22 f22 is seven stops down from f2 So now let's add three-quarters of a stop to that to account for the three-quarters of ten years and bam F29 is our number whereas f32 would be a full stop over f22 So yeah, I set my phone's light meter at f29 at ISO one Which I'm sure is a combination no light meter has ever seen before So I'm thinking Somewhere in there my dumbass did the calculations wrong either that or just reading light at extremely low ISOs Breaks it down in a way that I just don't understand Reciprocity failure is also a thing on this film But didn't really seem to help me out too much basically it was add half a stop a light after 10 seconds add a full stop A light after 100 seconds, but if anyone has any ideas on what might have gone wrong, please do inform I'd love to hear some theories on what might have gone wrong So in the end sailors beware It might be a good idea to test some strips of this film before you actually go shoot it If you ever decide to shoot it. So is this a valiant effort? No not really well This film replace HP 5 is my new black and white 35 millimeter film. No, will you ever shoot it again? No, what was the point of this video? I don't know. Did you ever think of an ending for this video? Or is it just gonna drag on forever?
