OFFICIAL RU-vid PAGE FOR SHYSTUDIOS! New videos every Saturday !! I do a variety of videos from in-depth tutorials, to stupid videos of me playing games, to cooking videos, and much more!
I tried to get the best film resolution I could using the highest res film at the time (Kodak High Contrast Copy Film - rated at 250 lp/mm). I used one of the sharpest Nikon lenses at the time mounted on a copy stand shooting a resolution target. I developed the film myself using the special development Kodak spec'd. The best I could muster was about 80 lp/mm. This was around 1980 (I know lenses are better now). A Photo mag around the same time tried the same sort of max rez test and managed 100 lp/mm. But still, real world, you're probably not going to do that well. From my film experience and digital camera experience, I think 35mm photography gets you 5 - 8 MP equivalent. Images from a modern high end digital camera are WAY WAY sharper and with a better contrast range than anything I've ever managed on film. Honestly my cellphone will do MUCH better if the light is good.
I worked at a shop once time and the guy brought his rig in with the side panel already off. From 5 feet away I could already smell cat pee. Well he said that he played a lot of fallout new Vegas and it was getting really hot and man this computer had a layer of dusty piss soaked cat hair in it. The bottoms was rusted out very similar to yours. I was like man, I’ll get the data off of it for you and clean it up, but I recommend a new computer. Well he just wanted me to clean his old one up (of course) which took me about two days because I kept getting so nauseous cleaning it. But, his old gtx 560 looked bice and clean and even though I soaked the heat sink in alcohol after removing the fan when you turned it on, it still had a piss smell that it ventilated through the room. Charged the dude extra for a biohazard fee. Disgusting. And then expected it to be my problem that his computer was so freaking nasty. People are ridiculous.
There's something that I have never seen addressed in these videos, and is the fact that, AFAIK, each grain in a film can only be either black or white (or, if it's a color film, either the color or black), which means that any light/color gradation must be done by dithering. So yes, you can have very small lines for very high-contrast elements, but as soon as you have normal-contrast elements, the image dithers and you loss a lot of resolution (which, BTW, explains the two values of lines per millimeter). Instead, in a digital sensor each pixel (or subpixel in the case of three-sensor cameras) can have 256 or more levels of intensity per pixel, so although the "apparent resolution" (this is, the number of line pairs per millimeter) is smaller, in practice, with "real world images" the resolution loss is not so extreme. Or that's my opinion.
Lenses are the biggest limitation. I think digital has driven lens technology improvements, past "quality" lenses obviously fall apart with modern sensors, so to get the sharpest digital pictures, they are making technically accurate lenses. I've got a few older lenses that were very expensive back in the heyday of film, and they do not acquit themselves well in front of a digital sensor. Fortunately we also have digital means to correct deviations, but the old adage of Garbage In Garbage Out still applies.
My wife an i are independent electronics engineers for industrial and infrastructure applications. Have seen much worse. Rat nest machine control panel. Rotten fluids of electrocuted rats causing a short. The smell of burnt electronics with rat poop and rat decompositions.
chatgpt explain : Here’s a more detailed summary of the idea of using entropy in the conversion from analog film resolution to digital formats such as HDR10+, with some scientific insights and formulas: Entropy can be used to measure the amount of information when converting analog film resolution into digital formats like HDR10+. In information theory, Shannon entropy quantifies the average number of bits required to encode information, which is essential in image processing. For analog film, resolution is often measured in line pairs per millimeter (lp/mm). To estimate the number of pixels required in a digital format: P = L × H × (lp/mm)^2 where L and H are the film dimensions in millimeters. In HDR10+, each pixel uses 30 bits (10 bits per color channel). The total amount of information (in bits) for an HDR10+ image is: Total bits = P × 30 For example, a 35mm film with 50 lp/mm results in ~2.16 million pixels, needing: Total bits = 2.16 × 10^6 × 30 = 64.8 megabits Entropy plays a key role in determining the visual information and optimizing conversion from analog to digital formats. Higher entropy in film (due to grain and tonal variation) typically requires more digital data for accurate reproduction.
I have lots of film negatives from the 1950's when my dad had a 70mm camera. I have a black and white 70mm negative that I used a Cannon desktop scanner to scan the negative at 9600dpi. A car in the picture that is more than 100 feet off into the distance, you can enlarge the scan of the negative enough to easily read the license plate of this vehicle 100 or so feet away. I highly doubt you can do that with digital photography.
nobody has ide to usb but there is plenty of people who have usb to ide. I have 3 of them and i am one of those tech people. Try suggesting to someone, even techs to find a usb to scsi (any, and there's multiple generations and types) or usb to SAS and THAT is a LOT harder.
In other words, get a good smartphone with 108 Mpx like a Poco X4/5 and you are good to go for another 10 years. Your investment will be swallowed by the cost and use of the phone. Try receiving a phone call on a 35mm camera or playing your favorite war game. With the infrequent use of the camera, it makes more sense to incorporate it into a more multi-use device. Whereas your 35mm spends 99.9% of the time in storage.
0:20 back in 2008 I did tech support for iMac users, the company I worked for was the only non-Apple support group to exist. We had a guy who got to a point where his computer needed to be brought into an Apple store where they denied working on it due to the large amount of tobacco dust. I was the third person who was unlucky enough to get a call from this abusive person. He was "banned" from calling in, his number immediately routed to an Apple agent. I was also the unlucky one who was tasked with reviewing the computer before making the ultimate call to hand off the case straight to Apple. he must have had a houseful o f smokers near the thing! at the time I was a smoker and even I had misgivings of touching the thing. I think I wasn't quite prepared as I didn't think it could get that bad. Even for me, I always went outside to smoke, so nothing in my apartment outside of my clothes had any smoke damage, and that was easy enough to maintain with weekly laundry. He even tried taking Apple to court over it. 🤣
It gets even worse when it comes to optical magnification (in the darkroom and elsewhere) as the effective aperture (and potential imperfections in the optics) further lower the resolution of film. Most magnifications in the lab are done at f8.0 max, f11-f16 are more commonly used. Wider apertures are only used for focusing the image. Now factor in the magnification and you'll end up with really small effective apertures, barely enough to resolve the negative. It's like spreading butter on bread, getting a bigger piece of bread won't get you a thicker spread of butter.
The worst I cleaned was a cat piss filled pc with dead roaches. It was rusted from the amount of cat piss in it, I'm honestly amazed I got that old IDE hard drive to last long enough to dump.
