Phound Photos Volume 10

Found photos sort of. I didn’t actually get any images that I can be sure of (stare at them for a while and you start to “see” things) but the scans are kind of cool.

I got a box camera recently and it had three film holders in it — 4X5 inch glass plate holders with dark slides to be more precise. One of the holders had plates in it.

There isn’t much info out there about processing old glass plates. Tons about scanning or making prints or preserving glass negatives that have already been processed but not developing old negatives. I processed them with Arista B&W paper developer from Freestyle, Kodak stop, and Ilford Rapid Fixer. The developer did the job — the exposed silver in the emulsion converted to metallic (black) silver. The trouble is, it was all exposed. Somewhere along the line, the dark slides had been removed.

This is a positive from the scanned negative.

This is a B&W positive from the first scanned negative.

I had to scan in two passes since the light source on the CanoScan 9000f isn’t wide enough. The exposure wasn’t quite the same but I was able to play with the levels and get it pretty close. I glued the half-images together in Photoshop Elements 15. Version 15 is kind of a POS (not point-of-sale if you know what I mean). It only has panorama stitch in “guided” mode and it doesn’t guess very well. It lined the images up OK but I could not get the exposure of the layers right. I ended up doing it manually with a huge blank canvas and two layers. I made one layer semi-transparent and picked a dot as my alignment point. Nudge, nudge, too far, back, SWEET! It’s not perfect but pretty close for moving the plate on the scanner manually without a straight edge. Once the layers were aligned, I set the transparency back to opaque, picked one layer and tweaked the mid-tone level .01 at a time until I couldn’t see the seam. Since it’s a gray scale scan, .01 would be one hundredth of 255 (0=black and 255=white).

I got a wild hare (hair?) and did the second image in color. I had to scan one half twice to get the exposure close. The Canon software “snaps” to an exposure level depending on how much light or dark is in the selected scan area — move the selection area in or out and the exposure varies in a huge jump. With the color information, more overlap, and using a straight edge this time (an SX-70 print), Photoshop did a much better job stitching the halves together and I didn’t have to do it manually.

This is a color positive from the second scanned negative.

Images of the camera and slide holders will have to wait until I feature the camera on 52 Cameras. I have some big film (not 4×5″ big, but big), print paper like I used for the cardboard box pinhole camera, and some Instax wide so it’ll be a fun project.

Note: Not my fingerprints — I used gloves. I’ve read enough to know gelatin emulsion on glass is really fragile and LOVES fingerprints.

Phound Photos Volume 9

These were on the memory card of a Sony DSC-H7. I’ll review the camera shortly since I know I can power it up and get things off of it. I scored the camera from Goodwill Central Coast in Salinas, CA.

There were 350 images total on the card, from June 2011 to November 2012. As usual, when I review the camera, I’ll link to this page so if the people run across the blog or YouTube channel, they can get their pictures.

It still feels weird posting other people’s images. Really old ones are easier. So far I’ve been lucky. No Jimmy Hoffa or Loch Ness monster but also no porn or wrecks or other creepy stuff. Maybe someday I’ll actually reunite someone with pictures they thought were lost forever.

Super Blood Wolf Moon — 20 January 2019

“Super” because the moon is close. “Blood” because of the eclipse. “Wolf” just because the January full moon is called a wolf moon. Some icy clouds so I wasn’t too optimistic but it turned out OK. The clock on my camera was about 20 minutes fast so the image time stamps are a little off. Images are shrunk to 1024 on the long side. Most with the Canon 60D & Sigma 18-250mm.

Here’s a good example of “crop factor” based on sensor size.The above image was taken with a Canon 60D, which has an APS-C sensor, and a 250mm lens. Because the sensor is smaller than a frame of 35mm film (“full frame”), the angle of view is narrower. For Canon APS-C, the factor is 1.6. You don’t magically get a longer zoom but the field of view is equivalent to the length of the lens times the crop factor. In this case, 250mm X 1.6 = 400mm.

Both images were resized to 1024 but no cropping. The size of the moon is the same for full frame at 400mm and an APS-C sensor at 250mm.

Back to the moon…

I switched from aperture priority to manual.  The moon sliver is too small for the spot meter in the camera.

I tried a Canon 2X teleconverter with the Kiron lens on the Sony for a total of 800mm.

I even tried a Kiron 2x converter stacked with the Canon 2X converter and the 400mm lens. It worked but the loss of light from the converters, the not-quite-perfect alignment of the converters+lens, and wobbliness of trying to aim something that long on a small tripod (while freezing) wasn’t worth it. The black spot is dust I got on the sensor while dorking around with converters with numb hands. You can see green chromatic aberration at the top of the moon.
2X + 2X + 400mm = 1600mm of wobbly goodness.

52 Cameras: # 162 — Nikon FM

    Things I forgot in the video:

  • The FM operates just fine without batteries — just with no metering.
  • The frame counter (36 max) is on the top deck just in front of the wind lever.
  • The LEDs in the viewfinder are used as a battery check.
  • Film speeds are from ISO 12 to 3200. Full stops are numbered (100, 200, …) with dots for 1/3 stop increments (e.g., 64 & 80 between 50 and 100).
  • Lift and turn the shutter speed knob to set the film speed.
  • The back can be removed for an instant or bulk film back.
  • The gallium photodiodes for metering are located in the eyepiece module rather than in the pentaprism. EV1 to EV18.
  • The meter is 60/40 center weighted — 60% given to the center 12mm and the remaining 40% to the rest of the image in the viewfinder.
  • No dedicated mirror lockup but it goes up when the self timer is used.

And… even reading the manual, I got the LED meanings wrong. + or means more than 1 stop off. Center dot and + or means 1/5 to 1 stop off.

From the manual.  Derp.

Film Photography Project’s “Retrochrome” is expired, cold-stored Kodak Extachrome. Ektachrome is pretty cool, color-wise, even when fresh.

I added another image of Goober (2 versions) because it was a funny struggle to get the colors right. The white sheets were really cool (blue). I tried tons of different tweaks and it was either still too blue or over-corrected and orange. I played with filters while I decided whether to not use the image or just convert it to black and white. Most results were “meh” but I like this solarized one.

Finally, just goofing around, I chose the “skin tone” filter. It’s supposed to correct skin tones that look wrong, usually because of lighting. I clicked the dropper icon on Goober’s face and, like magic, the colors in the image were right.
