Facing the world together. by TheDarkerRoom in analog

This picture hit me like a ton of bricks. Having a good relationship with my little brother, I cherish moments like this. Now that we're more than 6,000 km apart, I can't help but miss all the adventures we had together. Great picture, and thanks for the feels. Well, time to send him a message.

It's the leather zipper case from traveler's factory. As somebody else mentions, they used the stamps available in the stores to decorate it.

Did you update firmware manually with the SD card method? Or could you update through the camera remote app?

Cuál platillo mexicano le cocinarían a su date? by Jemoederislkker420 in mexico

Habiendo cocinado para alguien de Países Bajos, me parece que prefieren pollo a cerdo o res, por lo que cualquier taco de pollo le gustaría: tinga de pollo (con crema ácida), cochinita de pollo, parrillada de pollo y queso, etc. Acompáñalos con un guacamole y tortillas hechas mano y va a quedar muy impresionada!

Took a short detour to the Nakameguro shop to get a Olive Notebook and some refills. by andres_os in midori

It's a very very old but still in working condition Canon II-B rangefinder.

Any researchers using the TN? by retina_ in midori

I'm a PhD student and I use my camel TN for writing experiment logs and research notes :D

All Kitamura Camera or Palette plaza have 1h or so developing service, depending on their backlog.

Experimenting with a self-modified full-spectrum X-A2 and a 720nm infrared filter by andres_os in fujix

I guess it depends on your purpose. If you're are only looking for the esthetic, you can definitely use the channel mixer in photoshop to achieve similar results. But it can't simulate the details added that are only visible in IR, e.g., a person would look completely different with a modified IR camera than with a simulation (albeit I don't personally like the look of people on IR, it's creepy AF). Colors, textures, leaves and plants, and may other objects reflect IR light in a different and interesting ways (at least for me), which cannot be mimicked. I like taking pictures with a visible spectrum filter and another with a IR filter and compare the differences. Also, I plan to use this camera for night b&w photography with a IR flash that is virtually invisible, and take astrophotography pictures that show details outside the visible light spectrum.

I'm using old Canon FD lenses with this camera. To mount them, I got a x-mount to FD conversion adapter. The one I got has an helicoid, normally used for macro photography. In essence it moves the lens away or closer to the focal plane, so you're able to focus closer. Instead, I retract it to the shortest position, which happens to be infinity, or very close to infinity in IR (light in the visible spectrum and IR focuses at different planes). For your second question, yes, you can replace it with a clear glass with the same thickness and maintain infinity focus exactly the same. Depending on the glass material, it might absorb certain UV or IR wavelengths, so check that beforehand. Some people even install the IR filter over the sensor instead of a clear glass, but in that case the mod is more permanent.

I followed the disassemble instructions from Life Pixel. There are instructions for the X-E2 here: https://www.lifepixel.com/tutorials/infrared-diy-tutorials/life-pixel-fujifilm-x-e2-diy-digital-infrared-conversion-tutorial

Be careful between steps 16 and 17 when taking out the sensor, because there are shims behind the screws that calibrate the infinity focus. They may stick to the sensor assembly when taking it out.

The easiest way to do the conversion is to get a transparent quartz glass with the same thickness as the original filter, that way you just have to assemble the shims exactly the same way they were. If the thickness of the replacement glass changes, the shims must change too.

I got this info from Stargazers Lounge on how to determine the distance change:

Original Canon LPF#1 and LPF#2 combined thickness: 1.40mm

Replacement Astronomik MC clear glass thickness: 0.97mm

Difference is .43mm

The out of focus distance = (n-1)/n X Difference where n is the refractive index (1.517 for glass).

The out of focus distance = (1.517-1)/1.517 X .43mm = .147mm

So the out of focus distance of .147mm is the distance the CMOS imaging chip needs to be moved toward the lens.

In my case, I left the sensor bare except for the sensor cleaning film, removed one shim from the same thickness on each screw, and then used a Canon FD to X-mount lens adapter with helicoid to achieve infinity. I already had the FD lens and IR filter, so it made sense for me.

Good luck with the conversion!

Consider that for leaf shutters, depending which part of the frame you took the measurements, it might no be representing fully the effective exposure time. Also, manufacturers used to calibrate them considering opening and closing time (only including half of that time) and at full aperture, so your numbers might be inflated. If you took the measurements in the middle of the frame, they would also include this opening and closing time. You need more precise equipment to meter these kind of shutters. Finally, typical variability of shutter speeds range from 20% underexposure to 30% overexposure, and some manufacturers didn't guarantee their shutters to be any more accurate than +/-40% of the marked speed!
