Sepia Toning of Black & White Images

[SRTfan]

I'm trying to apply sepia toning to a black & white scanned TIFF image opened in the Photo Persona. All the guidance I can find is for photos brought into Affinity as color images and then converted to black & white.  I can't get any of that guidance to work on a black & white TIFF.  Would appreciate any help you all can give me!

Does Recolor help?

If your file really is 'black and white' - ie greyscale, like this:

then you'll need to convert it to one of the colour modes (RGB most probably) before you can colourise it. Pull down the Document menu, choose Convert Format/ICC Profile... , convert the Colour Format:

 

and you can then use a Recolour Adjustment (and others if desired) to get the effect you want:

Thank you for checking in and responding, RichardMH.  "Recolor" didn't work and neither did any of the other approaches (like creating a new layer and flooding it with sepia color).  I'm hoping h_d's approach will work!

[SRTfan]

Thank you very much, h_d!  That looks like it might work.  My first conversion looked like a gross overexposure of the original but I will keep trying.

I realised after seeing h_d's post that was mosy likely the problem.

Well, I tried your approach, h_d.  It made sense and looked very promising.  But unfortunately I can't get it to work.  After converting, I get a very overexposed, low contrast image.  It's not useable as a base image for recoloring and I can't improve it no matter what adjustments I apply.  I'm ready to give up, thinking that perhaps my TIFF scans just aren't compatible with Affinity for whatever reason.  I appreciate your and RichardMH's assistance!

@SRTfanCould you upload a tiff file for us to look at and test our end?

The basic thing is, that the image you want to recolour must have some kind of RGB (or even Lab, CMYK...) color space. It will of course not work with a greyscale color space. Then you must be aware of that you can't recolour black or white. To be able to recolour this both "colors", you need to darken/lighten them at least a little bit.

Thank you for your offer.  Here's the TIFF file, an unedited scan of a film negative.

Hi I converted it to RGB8 and used a fill layer with a sepia colour of R119 G66 B19 then changed it's blend mode to overlay and dropped the opacity to underplay the sepia colour. I've saved the file with History so you can scroll back and forth in the history panel to see what I did.

Here is how I would do it. Convert to an RGB file using Document > Convert Format...

Then I would get rid of all the layers you have in that TIFF.

Finally this

Play about with the Contrast in the Levels Adjustment and the Opacity of the Fill layer (note that it is set to Colour blend mode).

firstdefence, Old Bruce and iconoclast: 

Great! Thank you all very much.  Lots to chew on here.  Even though I've had Affinity for a while, I'm not yet very familiar with it.  Every time I try to do something it's a new learning experience.  I will follow your guidance and see where it takes me.  Thanks again!

Seems great minds think alike lol!
