Thank you for choosing Valoi's easy35 for your scanning needs! As part of our commitment to ensuring you get the best from your purchase, Valoi is delighted to include a special gift - the Vlads Test Target (VTT) professional sample.
This little powerhouse might seem unassuming, but it holds the key to unlocking the full potential of your scans. It's not just a strip of film, it's an invaluable toolkit that empowers you to get sharp, accurate scans from your cherished negatives and slides. With the help of the VTT, you can easily adjust the focus, control the camera view, pinpoint areas lacking sharpness or unevenly lit, and much more. It's a precision instrument that ensures you capture every precious detail. The sample on view is "abbreviated" version of so the called "35 mm Align Strip"
Read my blog post "Using Vlads Test Targets to Fine-Tuning Film Scanning Rig" to learn more about how VTT came to being.
So let's warm up your scanning rig. Get the sample strip inside your easy35!

What a joy to work with adapter with no wires attached!
Note the marks delineating different parts of the frame. The numbers represent actual sizes in millimeters, ensuring what you see in your camera viewfinder accurately corresponds to what you will see when you insert your original film.
Note from Vlad: The VALOI easy35 holder is designed with high precision and minimal tolerances. Some free samples of the '35 mm Align Strip' may not have been prepared with the same exacting precision as the holder, potentially causing issues when inserting and moving the sample through it. The easiest solution is to trim 1mm off the top of the sample strip using scissors, which should resolve the problem.
Step 1. Focusing the lens
The central frame, is the one you will be using the most: it is your go-to tool for obtaining crisp film scans. This frame includes five Siemens stars - one central star and four near the corners. When you're ready, load your film strip into your easy35, Valoi 360, or any other film holder of your choice. You'll want to focus your camera on the middle star. Achieving the best focus should be straightforward as the star's design offers clear visuals when in focus. Now, check if the remaining four stars are also in focus. If they are, great! You're all set up to start scanning. Switch out the VTT strip for your own film and you're good to go.
If any set of stars is not quite in focus, it implies that your film holder isn't parallel to the camera sensor. You'll need to address this issue by scrutinizing and adjusting your setup, making sure all five stars are in focus. Given the VTT's high-contrast nature, making these adjustments should be simple.
The most challenging scenario (which hopefully won't come up) is when the central star is in focus but the corner stars are not, or vice versa. If you encounter this, the most likely issue is with the lens you're using. To put it simply, your lens may not be suitable for film scanning due to lack of a "flat field of view". This means that although your lens (or lens with extension rings) might work well for 1:1 magnification tasks, it might struggle with flat objects like film frames. While a macro lens might be perfect for photographing a flower or a bee, it might not deliver the same quality results with a film frame. If setting your lens to aperture f/8 doesn't solve the problem, you'll need to consider other lenses. A carefully curated list of recommended lenses can be found in this brilliant article. In any case, the VTT has already helped you identify and eliminate an unsuitable lens, saving you plenty of time and frustration if you're just starting out with film scanning.
The entire frame of the Vlads Test Target (VTT) is filled with a meticulously printed grid or raster. This feature is also beneficial for pinpointing areas that are soft, meaning they lack sharpness, as well as sections where the backlighting might not be even. It's an additional tool to ensure the best possible scanning results and further fine-tune your setup. This way, you can achieve the best possible film scans and further eliminate potential issues that could affect the quality of your scans.

The actual raster grain being 8x8 pixel (for 30 MP sensor). The highlighted area is 40x40 pixels at 100% view.
Step 2. Adjusting view and scale.
The right frame on the provided Vlads Test Target (VTT) sample strip is designed for precise adjustment of your camera's field of view. This frame has several precisely drawn elements, with their actual live sizes indicated on the film. Once you've placed the strip carefully into the film holder, you can monitor what portion of the image is being captured.
The main window measures 24x36 mm, and as long as you can see it in your camera's viewfinder, you know you're capturing the full frame. However, if you need to slightly reduce the captured area for any reason (for instance, to avoid any extra light from the clear film rebate area or if your camera's gate differs slightly from the 24x36 mm standard), the frame provides marks to assist you in capturing a 23x35 mm area (typical for 35 mm slide mounts opening). 21x33 mm area should assist you with centering the image if other lines get obscured for whatever reasons.
This gives you a detailed visual guide to precisely frame your scanning area, helping ensure you capture just the portion of the film you want. It's a handy tool to fine-tune your scanning setup and achieve optimal results.
Step 3. Review the full line of Vlads Test Target's.
The left frame points you to the main product website and the developer's email address, which might not seem very thrilling, but I think it may help you find my other products for film scanning and darkroom printing. Interactive Parts Catalog below would be a great start.
So, whether you're a seasoned scanning pro or just getting started, I invite you to explore the array of sophisticated targets the VTT has to offer. Take your film scanning to new heights and transform your priceless negatives and slides into the stunning images they deserve to be.
We at Vlads Test Target as well at Valoi are committed to helping you make your memories last forever in the best quality possible. Here's to flawlessly capturing the memories of the past, the moments of the present, and the promise of the future!
