52 Cameras: #194 – Nikon Coolpix L310


Nikon still has the manual here.

I’ll do a separate “Phound Photos” post. The card had images from 14 Dec 2012 to 11 Jul 2013.

A minor mod of a SodaStream® Jet

Back story: I stopped drinking sweetened sodas a long time ago but I still polish off about a liter a day of plain or flavored/unsweetened fizz water. That adds up money-wise and worse, it’s a lot of plastic. Santa Fe has a decent recycling program but it’s at the mercy of the market and it only takes one lazy moron to contaminate the drop-off dumpster and divert a lot of material to the landfill. M had given me a SodaStream Jet a long time ago. I used it for a while, got lazy, and stopped using it. For the new year, I decided to find more ways to reduce my footprint and dug out the carbonator.



They’ve expanded the product line a lot and there is a bewildering array of options.

By mistake, I bought the 1L Slim instead of the 1L Classic bottles. For whatever liability reason, the bottles are not returnable. A 2-pack is $20. Buying (licensing actually) a new gas cartridge was another $30. If I bought another set of the right bottles, I’d be in for $70 and have 2 plastic bottles I don’t want or need. Not gonna do it. Wouldn’t be fiscally prudent.
In my defense, all the packaging just says "Carbonating Bottles".

The threads are the same on the slim bottles so I just have to be able to get it into the machine. Enlarging the hole to insert the bottle through the bottom would mean removing a lot of plastic and the swing-out mechanism releases the pressure for unscrewing the bottle.
The bottle can fit, it just won't swing in.

I used a coping saw for the vertical cuts, a razor knife to score, and pliers to snap off the plastic (it’s pretty soft). A little touch up with some 200 grit sandpaper and it fits.

Figuring Out F-Stops – Olympus Trip MD

Like the Konica Tomato/Pop-10, the brightest f-stop is the only one given in the manufacturer’s literature. Unlike the Tomato, I couldn’t find information on line so I had to do it myself.

If you don’t care how I arrived at these values and trust a random web page, here’s a table:

ISO Flash F-Stop
100 yes 4
100 no 8
200 yes 5.6
200 no 11
400 yes 8
400 no 16
1000 yes 11
1000 no 22

These values are rounded to the nearest whole stop. YMMV. Not responsible for ruined shots, hives, divorce, or any negative outcome resulting from the use of this information.

The camera is dark gray or black but the LED lights made it look blue.

Trusting that 35mm really is the focal length and f/4 really is the brightest f-stop:
35mm / 4 = 8.75mm diameter with the lens wide open.

You only get F4 at ISO 100 and the flash popped up.

You only get F4 at ISO 100 and the flash popped up.

The area is what’s important for exposure. Focal length/diameter=f-stop only holds for circular apertures. For most, I treated the shapes like diamonds and used (b x h)/2 for the area. To keep things simple, I cropped in to the edge of the lens and then resized to 875 pixels so 100 pixels is one millimeter. Once I had an approximate area, I used the equivalent circle area to get a diameter. SensorsOne has a great calculator so I could just plug in the area instead of using a calculator and working backwards from area=π r² every time.

ISO 200 with the flash came out to about f5 so I rounded it to the nearest full stop at f5.6

ISO 100 w/o flash & ISO 400 with flash are ~ f8 (7.2 calc'd).

ISO 100 w/o flash & ISO 400 with flash are ~ f8 (7.2 calc’d).


ISO 200 w/o flash & ISO 1000 with flash are ~ f11 (10.3 calc'd).

ISO 200 w/o flash & ISO 1000 with flash are ~ f11 (10.3 calc’d).


The last one was still approximated to a diamond but I had to be more accurate as the apertures got smaller.
At ISO 400 & no flash, the shape got less diamond-like so 2 circles and 2 squares give f14.

At ISO 400 & no flash, the shape got less diamond-like so 2 circles and 2 squares give f14.


ISO 1000 w/o flash is a pill shape so a circle cut in 1/2 and a small rectangle approximate the area for f18.

Polaroid ProPack Revisited (with old non-instant film)

With the broken rollers and pinholes in the bellows, I felt like this camera didn’t get a fair shake. This will probably make more sense if you see the original post first.

I had some unopened film in the freezer…

Here’s the film:

VERSAPAN GAFSTAR - not kidding about the heavy base. This stuff is thick.

100 pack film is 3.25×4.25 inches so this is a little too tall to fit in a film pack. I trimmed it in the dark bag. My cutter won’t fit in the bag so I used scissors. It came out as an irregular quadrilateral rather than a rectangle but it fit.

I haven’t repaired the bellows so I wrapped it, similar to the job on the Kodak Six-20.

The setting for original pack film on the camera is ISO 80 but Fujifilm FP100-C works without adjustment. From what I can find (not much) the GAF Versapan was ISO 125 when new. I’ve had it frozen but I don’t know its history so I figured it lost some speed. I got it backwards in my head and adjusted the Polaroid’s exposure dial to darken about 1/2 click. It is a bit dark but I didn’t have to do much post-processing, just cropping and dust cleanup, so I think this film is still ISO 100-ish. Developed for 5 minutes in HC-110 dilution B (1+31). I’ll have to do more testing. Now that I know it works and have a rough idea of speed, I can make 116 film and use some more ancient cameras!

One final note. It’s pan film, as in panchromatic, but the color sensitivities are interesting. And… never mind the cats knocked the balloons off the chair so I can’t map the colors. Any way, the colors are interesting. More testing to come.

52 Cameras: #191 – Polaroid Super Colorpack


I forgot to add it has the standard lighten/darken control around the light sensor.



Only seven images including the ones in the video. I used three testing another camera.

Mercury Transiting the Sun 11 November 2019

It was super windy and the old 400mm definitely does not have image stabilization. I got lucky during a short lull.

Sony A7, Aperture Priority, 1/60 second, Fotodiox FD-E adapter, Prospec 400mm (FD) @ f8, Vivitar 2X Teleconverter

The teleconverter loses 2 stops plus the filter material I had left over from the eclipse. Mercury is at about 1:00. Not great but comparable to the live stream from the Griffith Observatory. I may be alive the next time it’s visible from North America but who knows? Best to grab it while I can.

52 Cameras: #189 – Minolta A5




We were going to go up Truchas Peak but all of the land grant entrances were locked. One of us had been trying to get a hold of the president for over two weeks. The ranger said it had been open all summer but I guess we were too late in the season. We started going on a hike-for-the-heck-of-it from Santa Barbara Campground and tried Trampas Peak on a lark. We didn’t summit but did OK considering how late we got to the campground after trying every way to Truchas we could find on the map.

I’ll try some exposure stacking – bracketing gave me some good sky-dark mountains and the reverse.

It had been windy - some big trees down.
