    Re: New 75mm Hypergon Lens

    At least once during dry runs, I dropped the lenscap while trying to insert it. So I beveled the inner edge and added a knob to make the cap easier to hold.

    Hey, where did you get that green cutie? I was thinking of adding something like that too.

    Don't know why the images don't show anymore. I re-loaded them in post #159

    I used Rustoleum flat black. I know it sticks well to metal.

    I had been researching "Black 4.0" but I did not look that much different than other flat black paints I have used in this believable video below. All the other videos out there indicate it is so black you can't see it ha ha.

    Apparently the manufacturer of nanotube black paint does not market it to consumers.

    I believe that is from one of the kids games (I found under the couch)...don't tell them..


    I just went outdoors and did another test with the blackened spinner. 6+1 seconds f32.

    In the Jobo now.

    Just had a peek at the negatives. I'm processing the one from yesterday with the shiny spinner and the one from today with the black painted spinner. Same scene and exposure.

    There is a difference! Images to come...

    Much much improvement, but still about 1" of fog right at the center.

    So, I still need to do some work on the inside of the spinner. I think it needs to be perfectly smooth where the screw sticks through.

    The negative on the left is with the shiny spinner.

    The negative on the right is with painted spinner.

    Close but still not there yet. There is still an area of fog in the middle. This could probably be corrected by making the inside of the spinner smooth like the vintage Hypergon pictured below.
