Type 120 targets

 Quite a few folks IM'ed me if Type 120 targets will be available any time soon. The answer is yes, i am working on that. The issue with the type 120 design is that folks have different film formats: 6x4.5, 6x6, 6x7, 6x8, 6x9 - that means that the target will be comprised of at least two adjacent frames of 6x6 ( i will be shooting with Pentacon Six i own) so USAF patterns should be located across the frame in such a way that by repositioning the film in a holder each person will be able to have one pattern in the center and couple of them close to the corners. Most likely that means that 6x6 frame will have nine USAF targets and may be more. The gap between frames on film might fluctuate - that's known issue with the Pentacon film advance mechanism. My current 36x24 design will not work so all new chart has to be produced, printed and glued together. If anyone has a better idea or want to lend me (or at least recommend particular camera make i can rent from Adorama) of a 6x9 camera with the decent lens - around 120 mm - I am all ears. Adox film is not available in type 120 rolls, seems i will be using Agfa Copex Rapid - which have a decent contrast and grain ( I already have three rolls waiting to be put to use for starters).

Digitize Your Film with Confidence - Introduction Page

In this innovative offering, the ten USAF 1951 test patterns are strategically placed throughout the 24x36mm film frame - one in the center, and the others scattered across sides and corners. This unique arrangement facilitates a comprehensive evaluation of the sharpness and focus across an entire negative or transparency/slide in one shot.  P hotographers can now accurately evaluate the performance of their lenses and camera systems across the whole frame. This is particularly advantageous for detecting any discrepancies or weaknesses in image quality, which might typically go unnoticed with conventional  single-pattern USAF 1951 target needing to be moved in camera field of view. 24x36 mm target on 35 mm Adox CMS Pro film Clean, nice, sharp corners make or break the great scanned image    Welcome to www.film4ever.digital - the home of  USAF 1951 Resolution Chart on real 35 mm and 120 film aka Vlads Test Target !

Using Vlads Test Targets to Fine-Tune Film Scanning Rig

Part 1. Using Vlads Test Targets to Fine-Tune Film Scanning Rig So you decided to scan your film yourself. These days this  is quite a common and wise decision. You either decided to convert the priceless shots in your film archive or you just started your journey as a film photographer and want to share your best (and worst :-) ) shots with friends and mentors. You have to convert your film shots into digital form and be able to share them with a  click. The task is not new and since at least 20 years ago was widely available everywhere - from chain pharmacies to professional photo labs.   The option to save money has always existed  - you would buy your own scanner and off would you go. Many folks went that route and got lost. The time it would take to scan a few frames or a roll of film was anywhere from 10 minutes to hours. Paying extra 7-10 bucks for scanning was no longer such a costly proposition.  Fast forward to present times.  The landsc...

APO Rodagon D 2X 4.5/75 mm vs. Sigma 2.8/70 Macro Art - Fight of the Century

Image
If someone would want to compare the full size .png exports from the camera scans taken with Canon EOS R camera and APO Rodagon D 2X 4.5/75 mm and Sigma 2.8/70 Macro Art here is the link  https://drive.google.com/drive/folders/1-2cN8blD7M6xQ9T-bDM5cK9z2toPtTZq?usp=sharing .  The film original is "Vlads Test Target" on 35 mm Adox CMS 20 Pro film.  The pictures in the series were taken at shutter speeds no longer then 1/160 sec at full range of lens apertures. The aperture setting is included in the file name. The folder QuickCompare contains the same images, but less informative parts of images were cut out so it's easier to compare the files.   Full scan: Abbreviated file: I would suggest to download the files locally and use Lightroom or similar app to review images at 100% - otherwise you will not see the differences. Let me just note that the scans resolution is limited by the camera sensor, not by the lenses. See my previous post for details:  https://...
