Hi There,

I know this thread is 3 years old, but I am wondering if anyone can follow up on the results of simply spray painting the fuming box to contain the iodine from leeching out ? I know Acrylic is resistant to iodine, so would a thick acrylic gesso also do the trick?

Though not strictly daguerreotypey, (it is related trust me) I have an idea to display some iodine crystals in a large glass container, but am wondering how to seal it so it does not poison the atmosphere. I am attempting to be somewhat archival here also, so that this set-up could last for at least a couple years without the iodine completely dissipating.

thanks!

Thanks for the quick response !

I just tried a 35 minute exposure, and only got the tiniest of the white area, still totally underexposed, but at least I have something. Will try a full hour (good thing its a still life), and cross my fingers.

Iam using rubylith for the developing. Whats a good guestimate of how long for the developing? Is 8 hours too long ?

thanks again!

Also the studio lights I’m using are tungsten photo-flows. Should I try using daylight strobes instead? (those are the only other lights I have available right now).

What f/stop was used on the lens?

f.8.0

Subject to lens distance?

not sure, distance from lens to subject is about 1.5 meters

EV (exposure value) measurement using a light meter?

10.6

Irv

not sure how to calculate this…

phuphuphnik, thanks for the tips.

do you think its possible to try to put it back in the hypo after I’ve already took it out and dried it off? or should I just re-shoot it completely? I’m scared to kill my plate.

Ive been developing it in the sun 2 hours, not under lights, its pretty hot out though so I put two fans on it.

Thanks phuphuphnik!

OK, this is my first Dag I have done all by myself, without assistance, pretty good I think. But a couple of questions:

-I only did a minute and a half exposure in bright sun, it looks underexposed, correct?

-There’s still a bit of a milky haze, I developed the becquerel in bright sun for 2 hours exactly with 2 fans, so hopefully heat is not an issue. Could I have also over-developed it?

-I counted 45 seconds of fix time, though this seems kind of hard to decide…

Tomorrow I will try the exact same image at a similar time of day and sun, but a bit longer of exposure time… say 2 minutes, 15 seconds? (45 seconds longer) or should I do a smaller increment?

Thanks!
