35 mm alignment strip

Image
  Vlads Test Target has addition to the family - “35 mm alignment strip” "35 mm alignment strip” is the high precision test target executed via high-fidelity laser printing on specialty Agfa-Gevaert photographic film. Because of how it's made, the image elements are geometrically perfect - lines are straight and parallel to each other, the fine raster is very uniform and is distortion-free.   IMG_20221225_153412141.jpg What does that bring to the field of camera scanning? The target geometrically resembles a 35 mm film strip (type 135). All markings on film are per the spec, including the 24x36 mm frame which corresponds to the typical film camera gate. While positioning the strip in a scanning film holder, user can observe exactly how the actual negative will fit in the film holder and any parts which might be exposed or obscured. IMG_20221225_154220492.jpg The target also contains marking 23x35 mm depicting how a typical mount would mask parts of the frame to remove the edge

Vlad's take on the current campaign to promote “Euphoric 100” film from Atlanta Film Co.

Here is my take re: the current campaign to promote “Euphoric 100” film from Atlanta Film Co. ( https://www.atlantafilmco.com/product-page/euphoric-100 ) The availability of Kodak EKTACHROME 100D in 36 exp rolls at the lower price is a very good news For certain, the availability of Kodak EKTACHROME 100D in 36 exp rolls at the lower price is a very good and healthy development. So it’s a bit counterintuitive that offering the top shelf color reversible film at a lower price point is not what Atlanta Film Co is spotlighting. Instead, they are trying to reach the souls and wallets of the film geeks on almost subliminal level: here is the deep purple can, the Euphoric name, charming models in what appears to be bomb shelter setting, and bootleg-movie contrast and colors style. Enticing film photographers with the distinct style the cross-processed EKTACHROME The press release and the review in 35mmc.com by Molly Kate ( https://www.35mmc.com/.../atlanta-film-co-euphoric-100-a...

Pro-slide: New product announcement

Image
By the pure accident (to be completely honest I was just aimlessly browsing eBay ๐Ÿ˜€) I came across some strangely shaped GEPE slide mounts. They have 37.5 x 37.5 mm opening in the standard 50x50 form-factor and come with anti-newton glass covers.  The built-in flash popped up in my head: those mounts would be perfect for mounting the full frame slide if I ever want to project the slide with the rebate area and sprocket holes. The more utilitarian use for these mounts would be to use them to perfectly tune a scanning rig so exact  film camera 24x36 mm  dimensions would be available for framing.   Typical paper or plastic slide mounts have 23x35 mm opening to allow film frames  from the different cameras be mounted even if some cameras have the film gate of slightly varying height and width. Not only photographers have to be very precise while framing the view during the shoot,  they also will struggle with digitizing the mounted transparencies as the majority of the mounts are rather th

New Target Available ISO 12233:2000

Some folks asked about this chart - ISO 12233 - as they wanted the slanted edges to make certain measurements . It just happened I have them ready:  Limited number of these targets is available in MF format at my Etsy store https://www.etsy.com/shop/SilverKnits Note these targets are nor of high resolution, they are approximately  ~ 20 lp/mm due to specifics of production process.  Certain elements cannot be resolved properly - those areas are marked with red eclipses on the photos below. If you need high resolution you may use my 35 mm targets. (see also  https://www.edmundoptics.com/p/1X-Enhanced-I3AISO-12233-Digital-Camera-Resolution-Test-Chart/15688 ) The below pictures were taken at magnification x40 with the optical microscope.

How good 35 mm test target actually is?

Image
 I have been passed the question from the customer called Mark who provided the following feedback:  The 35mm targets I bought are good value, but aren’t as sharp as I’d hoped for. They are only just good enough to show the limits of my 16MP MFT sensor with 45mm Leica lens, but wouldn’t be good enough to explore the limits of the best full frame cameras and lenses. I’d probably need to buy a chrome on glass target for that, but that would be much more expensive. --Mark  I am actually happy to jump in and argue that my targets are indeed can help folks with the scanning setups of  decent resolution. For starters, let's look how 42 MP  (7952x5304) Sony camera resolves the test target. Chart 1.  Click on the image to see full resolution image open in the new browser tab.

Urgent Message from Vlad

Hello all, fellow digitizers! I am sorry if this message disturbs your otherwise perfect, worry-free state of mind. If this is the case I apologize and it will be perfectly fine if you scroll this post down.  Picture credit : Vladymyr Bysov    https://www.facebook.com/media/set/?set=a.10216683362795518&type=3 For those who agrees to read further,  I say - Ukraine needs help. It needs help right now as it is under attack which soon will be at the scale not seen since the World War II. My native city of Kharkiv - often referred to in the press as the second largest city in Ukraine - is under unprovoked, absolutely brutal attack. Above is the picture of my city taken at a better time by my good friend and outstanding photographer and researcher of Kharkiv history Vladymyr Bysov.  What I am asking everyone of you is to make a donation to the charity of your choosing or to Ukrainian Armed Forces. Whether your money will go toward humanitarian purposes helping displaced families, or  the

Short 55 seconds video of live-action

See Vlads Test Target in action in this short video.  The video was taken from the back of Canon EOS R with a video camera.  The irony is that focus peaking does not work if an external monitor or a capture device is connected to the camera, so I had to resort to shooting the video the old way ;-). Click on picture above to play the video - will open in a new window. Sorry, if you allergic to Facebook, but for pure business reasons I host video off Facebook.

New 4x5 Test Targets are available now!

Image
  New 4x5 targets have arrived!  This is how new 4x5 target fit Pixl-latr holder This is how new 4x5 target fit Pixl-latr holder Here is some features incorporated into the design per folks' suggestions. 1. The targets feature thin grid with grid lines distanced exactly at 10 mm throughout the image. That allows to track any distortions and make actual measurements on the film. 2. Grey border goes around the edge, this is thin raster which should help with analysis of uniformity of back light. Ideally you should be able to cut out piece of that band in PS and then move it around without observing any differences in raster features( dot size, distance, brightness between raster dots).  3. There are numbers supplied across the board to help with the assembling and stitching the image.  4. Siemens stars and USAF 1951 patterns are mostly supplied to help keep focus in check. The stars and patterns are very slightly misaligned - again to help with the stitching in post processin
