Problems with duotones in LR

[Antonio Correia]

Hello everybody !

I start by making a black and white image, saving it like as tif file, then returning back to LR to apply the duotone.

However, several of the 41 images I want to print look like having different tones, perhaps just because they are very different in lighting modes and tonalities.

I am rather upset because I wanted to print them in duotone but I have to go back and print them all in simple and plain black and white, so I can have a persistent and consistent images in the exposition I am about to do.

Any help please for future works ?
Thank you !

Bom dia Antônio,

I don't know if this is the cause of the problem you are experiencing, but as the "Split Toning" adjustemts in Lightroom allows different colours for the highlights and the shadows you can have a different "colour balance" for photos that are differently lit.

Lets say you give the highlights cooler tone and the shadows a warmer tone, a bright picture will look cooler to the eye while a darker picture will look warmer.
That is expected.

Best regards.
