See my [[Micro-photography]] note for how this project started. For the second round, I decided to connect the Zenit directly to the microscope’s camera mount instead of attaching lenses one by one. The microscope came with a **1x eyepiece mount** for cameras, so I used that to attach the body. ### **What I found** 1. **Magnification issues** The 1x eyepiece mount worked, but the magnification was nowhere near as strong as the **25x eyepieces** on the main viewing tube. This makes sense for digital cameras, since they can zoom in digitally. But with film, that “extra magnification” just isn’t there, which makes it a limitation for my setup. 2. **Focus challenges** Getting the correct focus is still tricky. The **distance from lens to film plane** is extremely sensitive—just a small shift can ruin sharpness. 3. **Circular samples in the photo** In the viewfinder, I could see the sample filling the whole frame as a rectangle. But when the film came back, the images showed up as **circles inside the frame**. I’m not sure yet why this mismatch happens, but it’s something to look into. 4. **Exposure experiments** Exposure continues to be an issue. I tested shutter speeds at **1/500, 1/250, 1/125, and 1/60**. Out of these, **1/60** gave the closest to correct exposure, but there’s still room to refine this. 5. **Next steps** For the next experiment, I’ll try: - Longer exposure times - Higher magnification eyepieces - Directly mounting higher-power microscope objectives to the camera, since that actually gave more promising results than the camera mount in these first two trials. ### Here’s the setup for this attempt: > [!figure] ![[MP-Setup-2.jpeg]] ### And here are some resulting images: ![[MP2-IMG_01.jpg]] ![[MP2-IMG_02.jpg]] ![[MP2-IMG_03.jpg]]
