[@jm200sx]

i wish i didnt see this video, it made me question my whole reason for working in the darkroom. Amazing results, just amazing!!!!!

[@AlexBurke]

Hahahaha! Nothing quite matches the feel of darkroom work so hopefully you keep it up! Thanks for watching!

[@NicholasAndre1]

I used to do printing of Ektar 100 onto Kodak paper. You can run the RA4 process for Kodak paper at room temp and the results were absolutely beautiful. With Ektar you could blow the frame up optically to 16x20 from a 35mm negative with no grain. Being honest, the quality of it really put me off of digital for quite some time, especially the color handling around highlights. Sadly maintaining an RA4 darkroom is no small task now that I'm leasing and moving frequently. They also discontinued cut sheets of paper back in 2011 I think, but the rolls do work for optical printing if you have the patience to cut them up. The papers they have are pretty amazing, albeit there are no real grades available anymore so there's only one contrast and saturation possibility for a given negative. I actually still have quite a few boxes of the Kodak RA4 paper back from 2011 although it hasn't been stored particularly well. Should give it another try sometime now that 4x5 dichro heads are basically being thrown out.

[@stratmancruthers]

I was a scanner operator for a many years, ran a Crosfield 646 horizontal drum scanner and then a Hell scanner like the one in your video. The last scanner I ran was a flatbed Scitex scanner, nowhere near as good as the drum scanners, you couldn't do oil mounting with the flatbed which made for dusty scans. Was a great trade back in the good old days of print.

[@Newrivergraphics872]

I trained in color scanning in printer college, 1988, (years ago) but could not find a job operating a Hell Color Scanner. I did work in pre-press though. I even worked on the National Geographic Magazine in pre-press. I also visited printing companies in NY and Delaware, on some field trips. They demonstrated, in 1988, software called Scitech or something like that that was actually like Photo Shop today. The new desktop computers changed everything. What I saw them doing up there, on expensive equipment, can now be done on desktop computers. Most photographers , including myself, don't shoot slide or negative film today They shoot in digital and they don't shoot in medium format. Since digital came, drum scanning is old technology.

[@AlexBurke]

That's a cool backstory! Yeah there's been a lot of changes in the industry. Prepress hardly exists in the capacity that it did before, it's almost done entirely by the photographers themselves. It's still pretty impressive what a drum scanner can do with a great slide or negative.

[@pakan357]

They are truly amazing. And to think not even drum scanners are equal. Your Heidelberg Tango is among the top in my opinion. The best scans I saw were from a Dainippon scanner. I can only guess how much would one shot cost. You could see the emulsion itself at 100 % crop. I use a Nikon Coolscan 5000, so when I can't get more out of my negatives, I can just say to myself that the next step would be a Hasselblad scanner or a drum scanner, neither of which I could ever afford. It makes me feel satisfied.

[@AlexBurke]

Glad you've had some experience with these amazing machines! I also agree with your point about how sometimes what you have is plenty enough. It was definitely a plunge when I decided to get into drum scanning. Worth it for me but certainly not something that everyone would want to dive into!

[@TaDao70]

@@Nobody-Nowhere where did you find a drum scanner for $500?!?

[@teresashinkansen9402]

I think the magic here is the way the film is mounted on the drum, placing a medium with higher IOR than air between the interfaces between the drum and the film will reduce reflections, fringing and increase contrast, I think this is the key, i wonder what would happen if I were to add some water to a flat bed scanner? of course after tinkering with it so it can handle the water.

[@AlexBurke]

People wet mount on their flatbeds all the time. Definitely don't use water, use a proper mounting fluid such as Kami. The difference is very slight on a flatbed. There can be a reduction in dust and scratches, and some people may find a little more sharpness, but it generally doesn't really work a miracle with the flatbed scanner optics.

[@CarlWicker]

awesome, wish i had the bucks for some 6x7 scans. :D

[@pl1532]

Question Alex. Whatever software you are using prior to the scan, don't you have to make different adjustments for each piece of film? With that said, to achieve optimal results isn't it best to scan each piece of film separately, rather than batch scanning film that may have different contrast and exposure values?

[@AlexBurke]

Good question, yes the software allows me to make individual adjustments to every piece of film on the drum. It's not treated as a batch but rather individual frames so I can perfect each one. For negatives, I have an exact profiled setting that I use for each one and then do the inversion manually after scanning, but with slides I make little tweaks to each image before scanning.

[@dazodiak]

How much does one of those scanners cost?

[@Martin-ci1og]

Great work, keep it up:D A little critique however I will give: you should upload your videos in 4K, even if you only filmed in 1080 because that way we the end viewer can have a better experience. Cheers:D

[@AlexBurke]

Thanks for watching, Martin! Currently I am trying out a new video software (as I'm sure you can tell photo is more my thing than video) and this version of it does not allow for 4k. Perhaps I will go with the full version soon.

[@lrochfort]

Out of curiosity, is this an 8bit or 16bit colour depth scanner? I recently acquired an 8bit 8000dpi drum scanner for the cost of shipping, and it's great, but you always wonder if the next step up is better again

[@AlexBurke]

It's a 16 bit scanner, which definitely seems to help quite a bit with color banding when you apply any edits to a scan.

[@PaulBostrom]

Hey! Currently looking at getting probably an RZ67, is it possible to make 6x7 look good as a 6-8’ wide print or is that too crazy?

[@AlexBurke]

That's always a challenging question and depends on your expectations. That's asking a lot from 6x7cm film, but the print would likely look quite good if you stood back to a distance where it can be appreciated in full. If you get close to the print, the grain size will be large and sharpness not all that incredible. But generally we shouldn't be viewing prints that closely anyway.

It doesn't really have any software solutions for that, but it wouldn't be very necessary either since it has such incredible dynamic range. A good, properly profiled base scan will have all the shadow detail that can be reasonably pulled out of the slide, then if needed shadows can be lifted with care using luminosity masks, etc.

It allows the engineers to create a very large image capture device (optics, tubes, electronics) that is highly focused on a small spot and relatively stationary while the film moves. It was likely an engineering challenge and this was the best solution.

[@ionluv]

I’m guessing this isn’t worth it for 35mm

[@AlexBurke]

Sure is! You can squeeze the most from smaller formats with a drum scan.

[@ionluv]

@@AlexBurke i imagine it’s even harder to load.

[@AlexBurke]

@@ionluv not necessarily, I can fit about 30 35mm frames on a drum. I just request that people send only the frames they want scanned, not full strips.

[@Frisenette]

4:05 BS! The CCD or CMOS sensor in a regular scanner is just as analog as the tube in the drum scanner. And the signal is made digital at exactly the same point in the chain. Drum scanners are redundant for anything but large format, which (sadly) is a niche of a niche. They are 1960s technology, that was found to be good for general film scanning in the 80s. The basic idea is long past due retirement though. Other smaller formats are much better served with camera macro scanning.

The key aspect of drum scanning is that photomultipliers are the sensor which has a completely different response than CCD or CMOS. A photomultiplier can count a single photon and is standard to calibrate lasers and high precision optical equipment because of that (for example the $100m plus photolithography wafer etchers used to make modern CPUs and GPUs). Technically speaking, if you know your light source profile, a photomultiplier has infinite dynamic range - because it can count photons - hence being able to resolve incredible detail from the scanned medium. It's a major departure from the modern combo of linear sensor arrays plus complex focus optics which induce light loss and optical distortion (also the reason why the X series of Hasselblad scanners use super expensive large format optics). While any contemporary Sony mirrorless camera can effectively "see in the dark" it cannot do so without noise, optical distortion and limited dynamic range. Even the fact that the sensor uses a Bayer arrangement means irreversible loss compared to a drum scanner capture. Ultimately, commercial reasoning dictated the demise of drum scanning because it's bulky and expensive to build - flat scanners are so much more profitable. Drum scanners are still workhorses in archival, restoration and forensics - I doubt there will ever be new hardware made though.

[@Frisenette]

Rearu Sato You don’t need the ability to detect a single photon, when you have all the light you want/need and more than enough time to pick it up/accumulate. The disadvantages of the Bayer array becomes somewhat less, when you have a high enough macro level, and do many overlapping shots. It would be nice though to have a bayerless sensor. The main problem with a drum scanner is that the aperture decides the resolution and the scanning action introduces artifacts. Therefore it’s not optimal for smaller formats and it isn’t even really optimal for large format if you want to max out the resolution (that’s rare though since there is so much).

@@Frisenette Correct: CCDs have high quantum efficiency and good linearity, which is why they are used by astronomers, and in laboratory situations. CMOS can nearly match CCDs now for sensitivity, but this not relevant in a scanner where there is a sufficiently strong source of light. It is also correct to say that the aperture of the lens determines the resolution of the image. This is governed by the laws of physics, as described by Fourier optics. Thus, at the image plane, to a fair approximation, the smallest resolvable detail expressed in micrometres is about 4f/3, where f is the focal ratio of the lens used to take the photograph. However, it is extremely difficult to achieve this theoretical limit for apertures faster than about f/5.6 or f/8, where lens aberrations become the dominant factor. Finally, the Nyquist-Shannon sampling theorem tells us that the pixel pitch needs to be smaller than half the size of the smallest resolvable detail.

[@Frisenette]

cdl0 you misunderstand. Drum scanners are variation on the flying dot scanner. They have an aperture emanating intense light, that is focused on the film. That is the smallest possible detail it can resolve. That is a real limitation, when you are talking medium format and 135 film.

[@cdl0]

@@Frisenette Yes, I see now. In fact both factors are relevant, namely the aperture of the lens taking the photograph, and the optical system of the scanner, which is also described by the laws of Fourier optics. This similar to a microscope, and is summarized by Abbe's formula, d = λ/(2NA). The practical limit is about 200 nm for λ = 550 nm. However, this is much smaller than the finest detail resolvable by the lens taking the photograph. If the f-ratio of the camera lens is about f/5.6, then the finest detail on the film (or a digital sensor) will be about 7.5 µm across, so the pixel pitch needs to be about 3.75 µm (or 3750 nm) to capture this without aliasing. Even with the budget of a space agency, it is not really possible to do better than this.

[@adamstreetboyzz]

Lmao it's as sharp as digital. Smh crazy lol

[@Ryan-lu9km]

Well, even medium format film is sharper than a digital full frame camera, if scanned with a drum scanner. Film is capable of really high resolution, specially slide film, if you can pull all the detail out. Even a 35mm slide can be fantastic. Until digital came along, slide film was the gold standart for really high resolution images, in magazines, National Geographic, and fashion photography, slides shined with their vivid colors, unmatched by any digital sensor until the modern digital era.

[@Eigil_Skovgaard]

No, I still don't have a clue. If this presentation should point at the differences the film material should be scanned on a flat bed scanner too and the results evaluated side by side. No real explanation is brought here to clarify why the analog conversion to digital representation should make any difference. This video just seems to be a new chapter in the ongoing hyping of drum scanners without bringing any scientific explanation of why a drum scanner should be superior.

[@danirabinowitz5049]

You've ruined all other kinds of scanning

[@migranthawker2952]

I reckon I get just as good quality from my full-frame dSLR. No point in using film!!
