Image B dag is constructed from SALT / HALIDE AgI.

Image M dag is constructed from METAL Hg.

/then about gilding/

Therefore it is possible to tell that:

B dag is HALIDE DAGUERREOTYPE.

M dag is METAL DAGUERREOTYPE.

Compare them on color. One chromatic color, another achromatic metal color.

This main and basic distinction of two processes.

Therefore technology B will differ from technology M.

Salt more fragile than metal.

Knowing 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.

BECQUEREL DAGUERREOTYPE – blue color. Is the MYTH.

Blue is not synonym BECQUEREL DAGUERREOTYPE.

Blue is not correctly made BECQUEREL DAGUERREOTYPE.

[botticelli1972]

I agree blue is not the correct result, just the one that happens the most often. For all the becquerel images I have made only three were not blue/blueish. They are truly beautiful and what have perplexed me and keep me going to try and achieve perfection. I think part of the secret is long development(as Gerard stated so long ago)in subdued lighting, it is what I am working on now. In my initial tests I have found that a plate developed 24 hours with lower light levels makes grays and whites not blues and blacks. I just tried one for 48 hours and it came up fogged, many possibly reasons for the failure. I have also been testing with letting the plate sit longer between iodine and camera exposures. Sometimes I feel that there are too many variable to try. Failure at perfection is exhausting, sometimes Ill accept a blue one just to have something to look at-Larry
