Tools – compur electronic 3 shutter

I inherited a compur electronic 3 shutter.

Without battery it will always fire on the fastest speed, 1/200.
It should accept voltages between 3 and 6 V, the plus connector is the upper one.
So far the infos I found.

A luster terminal fits precisely on the connectors, I use 3 AAA cells, 4,5 V are giving very pecise shutter times. And 3 1,2 V rechargable cells would be enough, too.
Maybe I will later replace the rubber band 😉


Tools – 3D Printer

3D printing is a tool I use quiete often, eg. lensboards, lenscaps, spare parts,…

First I used Googles sketchup, but since it got online only, it lost me due to restrictions

Mysoftware as now is freecad, fusion 360 (free) , openscad (t seems difficult at first but is fun to use, especially as you can throw .stl files in the editor window and at once get a solid form to work on)

So usually I throw the .stl file in openscad, define the path as a module and can work on it.

Like so:

module linhoflb(scale){
    import("D:/Dropbox/linhof_board_blank.stl");
}
difference(){
        linhoflb(1);
        translate([265,175,0])
        cylinder(h=6,d1=50,d2=50);
}

And you get this:

I decided to print a few lensboards for my Graflex Speed Anniversary to use them with some old lenses.

And – being on my way, I printed a few waterhouse stops too.

( waterhouse stops  : hole size = focal lenght / aperture )

(to get the focal lenghtof the oldtimers : projekt a light source on a paper and measure the lens distance to the paper when picture is sharp – the further away the light source the better (sun ?

Formula : 1/f = 1/g + 1/b   focal lenght = 1/distance object + 1/distance projection ) .

I know, its just a approximate value but its enought…)


Everything working great.

Tips & Tricks – cellphone negative conversion

Here is a wonderful tip for my cellphone configuration :

You want to peek at the positive versions of your B&W negative film strips.

Phones comes with an accessibility option that allows you to invert colors. What’s great is that you can assign this feature to the home button.

To do this, simply go to Settings->General->Accessibility->Triple-click Home, and then select the Invert Colors option:

Once this is set, all you have to do is press the home button three times in rapid succession in order to invert all the colors on your screen.

Now point your cellphone camera or loupe at the negative , press the home button three times – There it is….

Instant negative viewing !

Tools – Rondinax 35 U

This is a great tank.

You load the film in daylight, reel it in, cut it all in the tank.
Using 200 ml of developer and fixer for a film.
I get great results using the times for 1 minute agitation and taking 15% off.
If the tank is leaking usually you have to reseal the thermometer plug, it is really easy to diy.
I am impressed how easy you develop a roll without any darkroom or bag.
