Zone Plate at Clare Glens
-
These are taken with a 75mm zoneplate – a variation on a pinhole – no lense used here. I did these at the Clare Glens co tipp, i suppose they belong in the macro/close up section as they are micro environments – brought to live by the zone plate glow. Shot on neopan 400 120 roll on ensign 12/20 folding camera (1950’s) with 75mm zone plate attached after removing lens elements. Film home developed in rodinal 1:50.
Lovely work,
they look like they’d make beautiful prints-
Thanks for introducing me to the zone plate,
I must admit I hadn’t heard of it before,
but it makes for very interesting reading-I hope you don’t mind the link,
but I found this to be very informative-http://www.whizkidtech.redprince.net/zoneplate/
It looks like your exposures are spot on too-
what kind of exposure times are you using,
and apertures,
and do you meter?They do seem to be relatively short exposures-
Again lovely worik-j
Thanks. will check the link, haven’t seen it before and i’ve searched alot on ZPs so thanks. A very informative place is f295, lots of zone plate work there.
I meter with a handheld meter.
Effective aperature of the zone plate is f65. So i meter for f64, and add a dollop for good fortune. I metered these at 4 secs and exposed for 6. There lots of scope too for exposures up to 1/300 sec in length – well at iso1600 anyway (this is 400 pushed to 1600).
these are scans, haven’t tried direct printing from the neg.
There’s a small amount of workdone in levels as ZP images can be cloudy and low contrast.
