Converted in Photoshop, under Image, under Adjustment, under Hue/Saturation, under Presets and there it is - Cyanotype without having to play with color sliders. Course you might want to tweak your levels a bit before you save.
@marlboromaam selenium tones on warm photo papers produced blueish purplish tones. I used to use Agfa’s portriga rapid paper which produced some nice warm tones.
@kvphoto You know more than I do then. This past Saturday was National Cyanotype day according the 365 discussions, so I looked it up. Not something I will do a lot but, it made some interesting images.
@ludwigsdiana Thanks, Diana!
