'Crown' in camera cyanotype

In camera cyanotype shot in Braun Paxina 29, exposed 4 hours at f2.9. 6x6 negative single coated in new formula cyanotype sensitizer. Developed in tap water and citric acid bath. The digitally inverted negative changed to a shade of orange/sepia completely losing the cyanotype blue. I have desaturated the colour to reduce the orange which was quite strong. to

    @leisuresuit Thank you very much! This has been digitally inverted from the cyanotype 'blue' negative which I uploaded for comparison so the colours swapped to orangey - brown. I used the Photospeed New Formula cyanotype liquid but still needed a huge exposure time to get a strong negative :-)
