Ladies and gentlemen!
It is offered to your attention
4×5 Bdag Gerard Meegan 3 yellow cycle the exposition 7seconds f2.7 EV 14.3
Development lamp EV 12 = 10000 lux 16 hours
lens tessar 165 f2.7
Falling light EV 14.3
EV 14.3 = 50000 lux
EV 14 = 40000 lux
EV 14.3 it on 10000 lux is more EV 14!
The diagnosis:
Insufficient exposition.
Lethal outcome. The patient is dead!
The increase or reduction of time of development are not compensated with an insufficient exposition.
Conclusion:
Gerard Meegan has joked!!!
Then:
1. Why all about it are silent already more than 20 years?
2. Why we pay money for such books?
3. Why we pay money for such workshops GEH?
Can be GEH not take money for such workshops, and itself to spend money for the present scientific researches BECQUEREL DAGUERREOTYPE?
THANK Gerard Meegan!
HE HAS LEARNED ME AS IT IS NOT NECESSARY TO MAKE BECQUEREL DAGUERREOTYPE.
Excuse, I did not begin to gild it.

Blue is not synonym BECQUEREL DAGUERREOTYPE.
Blue is not correctly made BECQUEREL DAGUERREOTYPE.
to be continue
bailunParticipantKnowing physical and chemical properties HALIDE AgI, we shall open secret BECQUEREL DAGUERREOTYPE.
We know these properties?
Who when and where in sufficient volume has studied these properties?
Thank Irvy, John, Gerard!
But it it is obvious not enough.
Today it is possible to tell precisely, that B dag the technology offered(suggested) Gerard almost 20 years ago, requires revision, additions and modernization.
This technology works not well. The interest of failure is too great. It is possible to speak about what creative work, if resistance of a material appears so significant.
Technically good B dag the exception to the rules, than a rule looks more likely a phenomenon.
We as if gold-digger search for gold. One two particles of gold for weeks and months of heavy work.
The critical weight practising B dag for qualitative break in this technics(technical equipment) is absent. Units today.
But it not an occasion that we did(made) nothing and waited for positive reports of other practising operators.
We make it.
to be continue.
bailunParticipantPardon, Alan!
I did not write that a plate for daguerreotype.
Up to daguerreotype 10 more years remained, on other sources 8.
These are known things.
These are plates for continuation of experiences Geliograph if to be exact.
physautotype will be then.
Then – daguerreotype.
For now it is one of the first order for the polished silver copper plates.
Which we use now.
bailunParticipantIt is possible to see your successful dag? Thank.
Originally the idea of gilding has been realized not to paint Dag other color. And to make his(its) orange violet pink.
It was necessary to make less fragile and more durable, archival.
Principle of a photo – TO KEEP/safe the IMAGE.
About it it(he) wrote itself great Daguerre. spoke that his(its) attempts TO KEEP the PRINT/DAG/ with pitches varnishes rubber wax and so on have failed.
The desire was not aesthetics ornaments. And physical existence.
If you want to find sad and upsetting – you will find it. Why is not ?
Here suggested to strew silver sulfur for example.
And gold have chosen not because it yellow brilliant that is beautiful. That is why that through 5 thousand years of it(him) have taken from a tomb of the pharaon and it remained same as it(him) have put – gold. That that does not change.
Symbol of infinity. The god!
I do not love gold as metall. Ornaments and so on. /My lady likes/
But I am compelled it(him) to apply for dag.
Curiosity and economy once have opened America and then a photo.
But curiosity without economy – bad air.
Yes, mr John to use platinum entered into my plans. But as my name not Bill Gates and thank America for a global economic bubble / crisis, my experiences with platinum I lay off.
Your question about hand coloring Bdag looks interesting.
Likely I shall not be mistaken if I shall tell, that hand coloring Bdag does not exist yet.
There is an opportunity to appear first-ever painted Bdag and enter a history.
I do not like hand coloring dag. and blued highlights. excuse.
To paint all is possible everything and everything. But there is a problem of safety. What will be then?
Here the problem / unpredictability / in how will lead itself a pigment a paint in interaction not about mercury, and with salt AgI. and it and is Bdag.
Cadmium chromium ochre oxide titan of zinc and so on.
These are questions to dear mr John. it(he) the chemist and knows about dag all. It(he) can tell about consequences of interaction of these chemical elements.
By the way, originally Daguerre applied iodine to the pictures. It(he) mixed it with oil paints. Result naturally – accident.
At me one regret.
Why Bill Gates does not do(make) daguerreotypes?
We would sit and read here his(its) reports on platinum.
bailunParticipantSo
It is necessary to understand, that with gold at you has failed and other toner is necessary.
Please. Try chloride of platinum.
Is old reports about successful application of platinum.
What for it is necessary POP toners? I do not think that POP toners will solve a problem of gilding Bdag.
Here gold change for gold.
Only for dag apply pure(clean) chloride of gold, and for POP – burdened another not predicted for dag chemistry. What for?
Well to look that at you it has turned out?
Or you well gilded after the first successful dag and gold has already bothered, and it is necessary to search for other toner, or at you it has not well turned out with gilding and other alternative is necessary? Easier predicted and comfortable.
But such gilding for Bdag does not exist while in the nature.
Gilding is one of the most tragical operations with Bdag.
It is necessary to tell that the technology of gilding Bdag is not mastered up to the end well, as well as all process Bdag as a whole. It is in alive creative development. Many after Bdag either leave dag in general or aspire to leave faster in mercury / Mdag.
But Bdag it is the technological baby. Though it is open in 1840. it did not practise so much and well as mercury.
I think to us much still it is necessary to learn(find out) to open and investigate here.
Bdag on the present only begins.
And we can make it.
Excuse for bad English
