    Hello you all,

    Many info says that the rigth/best color after fuming with iodine is yellow with strong haze of pink/purple.
    Is this color ( yellow with pink/purple haze ) to be reached at the end of the first fuming with iodine before fuming with bromine ?
    Or is this color ( yellow with pink/purple haze ) to be reached at the end of the second fuming with iodine ?

    I hope my question is clear enough … I normally do not speak english …

    thx

    Marc

    Marc-

    First Iodine sensitizing to yellow with rose hints

    Bromine must be tested in steps. I use a strip mask to fume to 3,6,9,12 seconds of Bromine.
    I do not use color to determine my Bromine times.

    Second Iodine (“healing” the plate from the white light used to check color) is around 1/4 the first Iodine time.

    Recent shooting: 30 seconds 1st Iodine, 6 seconds on Bromine, 5 seconds 2nd Iodine = nice medium contrast plate

    Have a nice day,

    Hello,

    For my bromine box I use the recepy of Mike Robinson ( bromine mixed with cristals).
    For your bromine – fuming- time … the color in the Bromine-fuming box … is it yellow or lighly orange ?

    Grtz,

    Marc

    I mix liquid Bromine with silica gel. I try to get it bright yellow (“post-it” note yellow, if you have that product in your country). I’ve found that as the Bromine color heads into orange, it is too powerful.

    I also heat my plates with a blow dryer before fuming to accelerate the chemical reactions.
