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 0.06 ISO film That's right 0.06 not six not 60 Not 69 0.06 ISO and it 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 Radio graphs otherwise known as x-rays to slides with such a low ISO It took on average about 12 the 20 seconds to copy a radio graph 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 blue 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 was recommended to use DK50 developer But that's it 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 slash foolish enough to take this challenge head on So why don't you go follow his YouTube channel bad flashes You 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 role of them Whoa, look at that damn bro. Oh my god. That is literally the coolest Oh Oh 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 test song 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 I Got a really colorful sunset that evening which was perfect because I was shooting black and white Shooting directly into the sun with the 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 0.02 ISO instead of 0.06 ISO Which made things a little more complicated the reason I shot at 0.02 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 While we should be adding two stops a light because 17 years is definitely closer to 20 years I don't really think that's how the loss is it and I don't think it fly in court But yeah, I ended up doing the math and added 1.75 stops of light which gave us an ISO of 0.02 Now 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 in 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 0.02 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 0.02 that's roughly 12 and three quarter stops under ISO 25 Luckily the light meter on my phone goes down to ISO 1 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 at 0.02 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 10 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 1 which I'm sure is a combination no light meter is 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 Resiprocity 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 of light after 10 seconds add a full stop of 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 replaced 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?
