52 Cameras: #194 – Nikon Coolpix L310


Nikon still has the manual here.



A photo that was on the SD card when I got the camera.

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

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.

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.

52 Cameras: #187 – Canon PowerShot G10

Things I missed or glossed over in the video:

Canon still has the manual.

Scene modes: Portrait – “soft effect”, Landscape – deep DoF, Night Scene – slow shutter + flash, Sports – continuous shooting with AF, Night Snapshot – reduces camera shake (boosts ISO & shutter?), Kids & Pets, Indoor, Sunset, Foliage, Snow, Beach, Fireworks, Aquarium, Underwater, ISO 3200 (2X normal highest), and Color Swap.

Metering modes: Evaluative, Center weighted average, Spot AE Point/Center – spot metering is whatever is in the center of the LCD, and Spot AE Point/AF Point – AE point follows AF point (only works with FlexiZone AF selected).



No exposure modifications except the bird photo.
Some crops. For a P&S, it tolerates crops pretty well.

Open house at New Mexico Wildlife Center was awesome. It’s not on their web site yet but they have a “photographer’s day” coming up in November.
Lightened a little to bring the bird's face out of shadow.
