Thank you to everyone who gave me advice in my last thread.
I just wanted to post up the result of the wonderful piece of software that Thorsten recommended to me.
I’m really, really impressed with the result and I’ve only just run one photo through it and haven’t even started tweaking with the options it gives you (luminance, colour, sharpening, contrast etc.)!
It’s Imagenomic Noiseware software. I’m not sure if similar result can be achieved so easily with other software but I’m very happy with this so thank you Thorsten!
And here’s an extreme close up section of the results I got on one of my photos:
