to answer the hobbyists rudimentary question:

“Can anyone give me the times to develope(sic) FB paper in Ilford Multigrade paper developer. Ilford Ilfostop and Ilford rapid fixer? Thank you!”

in the land of time and temperature, it helps to be able to take the temperature of the room.

The direct answer is: https://www.ilfordphoto.com/amfile/file/download/file/1828/product/709/

Multigrade Paper Developer diluted 1+92 minutes1.5 to 3 min useable range
Multigrade Paper Developer diluted 1+143 minutes2 to 5 minutes range
Ilford Stop bath 1+1910 secondsup to 30 seconds
Ilford Rapid Fixer 1+41 minuteup to 5 minutes
absolute beginnings for Ilford Chemistry

… after more than 300 posts in the topic, it continues. Although, they no longer even try to answer the question, instead they answer each other — address each other as adversaries in a game of King of the Mountain. Among some, it seems they are playing Liars Dice, a popular game among the barstool photographers.

The simpler the question, the longer, more convoluted the answer. After enough time, we get into our deeper selfishness — pull out our basics.

how many old timers does it take to kill a thread.

Wiley is always throwing someone out of the store: Truitt and White.

Sadly, Mr. Bill gives credit to the vainglorious, and in doing so, takes it from himself. I wonder where he worked that he managed their color systems and is unable to see the errors Wiley makes.

The large portrait chains were called Kidnappers, since they offered free, or loss leader photos, then charged increasing amounts for reprints. The largest of the chain studios was Olan Mills, doing $475million (est) in 1993. Other studios: Varden, CPI in Sears, PCA in K-Marts, American Studios in WalMarts. Approximately $5B business in portraits in the US.

Lippmann Photography

absolute color… illusive illusion. Can we fix the light right without using a brain. Any one color can be produced using any of several color points. Change one anchor choice, you get a different range of possible colors.

The other way was Lippmann. interferential photography or interference colour photography, as well as Lippmann photography.

The method is very simple. A plate is covered with a sensitive transparent layer that is even and grainless. This is placed in a holder containing mercury. During the take, the mercury touches the sensitive layer and forms a mirror. After exposure, the plate is developed by ordinary processes. After drying the colours appear, visible by reflection and now fixed.

This result is due to a phenomenon of interference which occurs within the sensitive layer. During exposure, interference takes place between the incident rays and those reflected by the mirror, with the formation of interference fringes half a wavelength distant from each other. The fringes imprint photographically through the whole thickness of the film and form a casting for the light rays. When the shot is afterwards subjected to white light, colour appears because of selective reflection. The plate at each point only sends back to the eye the simple colour imprinted. The other colours are destroyed by interference. The eye thus perceives at each point the constituent colour of the image. This is no more than a phenomenon of selective reflection as in the case of the soap bubble or mother-of-pearl. The print in itself is formed of colourless matter like that of mother-of-pearl or soap film.[lippmann lecture, 1908]
