A closeup on an IKEA 'rack' in my 'den', which holds our network printer, scanner, network server ('ayeka') and some hanging files.
The printer ('azaka') is an HP LaserJet 4100TN network laser, which we can print to from anywhere else on our home LAN. I bought this from my office when they were engaged in a bout of new printer-buying in late 2005, and were selling off the older machines. The printer cost me somewhat less than a new toner cartridge for it, though thankfully at time of writing I haven't had to replace one yet.
The scanner is a Canon LiDE 35 USB model - currently connected directly to 'tenchi' (my main desktop PC), though one day I want to try linking it to 'ayeka' running a SANE scanner server, so we could scan from any other PC on the network. That's not exactly high on the list, though.
Made with my self made scanner-camera.
for most people this photo is a pointless shot of a building, out of focus, in a dark cloudy day, but I have decided to upload this to celebrate that I solved one of the biggest problems of my scanner-camera:
the RGB offset. It was not a problem itself, but when I was moving the RGB channels in place, there was a shadow of the other channels, so I had to do one scan for each RGB channel.. very boring.
The solution was so much stupid: I simply turned off the color correction in the Epson software (even when you don't touch anything it seems to affect the channels in some way) and that's it, a correct scan!
I made it not with the large format lens, but with the little tamron(35mm format) 28mm. very cheap, but is more convenient to use, and lightweight.
in the lower section of the photo you can see a color stripe, it's some dust on the ccd glass.
Con lo scanner da due soldi per pellicole che ho comperato su internet per non far stampare le rare foto analogiche che faccio e poi scannerizzarle ( oltretutto lo scanner del computer ora va male ), questa vigna me la ricordavo un po’ diversa….e poi da ieri ho la febbre alta, stasera sono fuori per lavoro ( e domani pomeriggio anche ) e mi sta risalendo a temperature equine, e poi mi fanno male le mani, spero non sia la schiena, quest’ inverno andrò alla piscina termale ogni volta che potrò.
I didn't entirely start from scratch.
I bought a Kodak Ektar 127 ƒ/4.5 used for $30. Someone was very honest about the shutter in it not being accurate. For this project I figured I would never use the leaf shutter aside from putting it on bulb or T mode. It seems by far the least expensive large format lens out there. The Kodak code on it says mine is a 1948 and if you look in the pictures of it it has the faintest purple lens coating.
The Doxie Flip scanner I planned on buying used but when I was on vacation with my family and my mother had a lifetime of 4x6 photos. I paid retail for it so I wouldn't have to wait for an ebay auction to close or something. Scanned many family photos and shared them with my siblings.
The scanner has so many things good for this project - being battery powered, being made to be used creatively, the window on the bottom. Unfortunately Jpeg only and not ultra high resolution.
Lets put them together into a camera.
At old school, slide duplicator is used to copy and make additional slide set from existing ones.
At new age, digitalise slides are done by using film scanner.
This is an attempt to do poor man's scanning: use a full frame DSLR to copy slides to raw then process to jpg etc. I am very pleased with the result.
It offers more control, dust control, and much faster.
See this sample for slide
and this sample for b&w neg, with some PS work on grain, contrast and brightness

..I had some problems trying to put the battery in place, but after some adjustement, it fits perfectly.

Note: Flickr makes a .jpg of uploaded files. The Jpeg process reduces actuance. The original scan has more detail than the .jpg file and in turn the original scan has less detail than is on the film. The film probably has 4 to 9 times (2 squared to 3 squared) the detail as you can see if made with a cracker jack lens and top rated film.
Gentlepersons:
This is one of three uploads to show the comparison between a good flatbed scanner and a good dedicated film scanner. Please use the download and/or view all sizes button, which will take you to a page where you can see the original. Tap on the original, then look at the detail on the license plate to see a proper comparison.
The Pictures in General...
These recently uploaded pictures have no artistic value. They were just uploaded to be representative of color picture recording during about 95+ years that I was able to take pictures, mostly slides at first. Unlike in today’s digital world it took time, money and effort to make a color slide. We took fewer pictures back then, trying to stretch resources, but some sere still frivolous. The first picture I remember taking was in the mid-1920s when my mother's sailor boyfriend brought an overseas camera to San Pedro.
I’m almost 97 (2016)and all tuckered out. I probably will not post much more. The ratio of today’s digital pictures that are kept for any length of time and/or printed is much less than the film photos taken in days past. History will be lost. Meanwhile you get to be bored by some old Kodachromes, Agfachromes, Anscochromes, Dynachromes, a few Dufaycolors and perhaps an old black & white or so.
This picture in specific…
The Camera: Rolleicord V, ca. 1954
I used a used but good condition Rolleicord V ca 1954. It has a single coated Schneider Kreuznach 75mm F:3.5 Xenar four element lens. I bought a second one so I could make medium format 3D (Stereo) slides. The two like cameras are less than 100 serial numbers apart but the second lens is not up to the quality of this one. Using the USAF1951 chart this lens gives over 60 lp/mm at F: 11. I would have liked to have bought a new Rolleiflex with the Planar lens but I was raising a family and trying to build some equities to suppliment my old age pension some years in the future (at that point).
The film, Fuji Velvia ISO 50 (old):
This was shot on the original formulae Fuji Velvia ISO 50 in about 1997. Velvia was then billed as the top dog in the punch colors race, at least by Fuji. The manufacture rated it as having a very low 9 RMS grain value and 160 lp/mm at 1:1000 contrast ratio with 80 lp/mm at a 1:6 contrast ratio. It was a sharp, tight grain (actually dye clumps) film. A Nikon 5000 ED or 9000 ED only resolves about 78 lp/mm. When used with a top rated lens, there is still detail on Velvia 50 that one can view through a good microscope that top of the line scanners cannot reproduce.
The Scanner, a Nikon 9000 ED
The Nikon 9000 ED is the medium format big brother to the Nikon 5000 ED. It too was rated by the manufacture to scan at 4000 PPI. Unlike most other scanners testing with a glass plate USAF 1951 with the resolution chart metal deposited on it, showed both vertical and horizontal resolution to be very close to that figure. When scanning a chart at maximum resolution one has to be concerned with registration between the lines on the chart and the pixel placement of the sensor. Exact registration is a hit and miss, re-trial exercise. With film the scanned bits of silver and dye clumps are randomly scattered without the need to have perfect alignment. I’d rate the 9000 at or very near 4000 PPI on film. Most scanners are over rated by 50-100%
This is a test about compare some filters with my self made scanner camera.
the last two in the lower right corner has a circle in the center because the filter was smaller than the lens.
I have done the test because i'm not very sure that the IR/UV filter is good. from the graph seems to cut at 680nm but the colors even with the filter are not very realistic.
I can't write any conclusion because im not sure if the 680nm filter is really 680 and how's the cutoff curve.
We lowered a few hours work down into the cave.
We had many days of over 100 deg F and as we kept looking for and finding caves and blowholes with a cool breeze, we decided to occupy this one for a few days.
We upset a few swallows nesting in the shade of the entrance, but they settled id as the evening came!
