Duplicate Layer >> Changed Hue >> Applied Threshold >> Changed Saturation >> Applied Gaussian Blur filter
First off did you apply all those changes as Adjustment Layers/Smart Filters?
Secondly I am not sure I understand what you are trying to do exactly.
Could you please explain more clearly and maybe post screenshots (with the pertinent Panels visible)?
Thanks for your quick revert. I am trying to simply convert the original image to the target image (both shared above).
This is my first time hands on with Photoshop so I am not sure I can explain you exactly like a UI developer but I would still give it a try. Please review the the attached screenshots, hope that will explain:
Can you please explain if I am following the right steps? If not, you can suggest me a better one. I think I am very close but still the detailing is not achieved. Let me know if you need more info.
Try reducing the Gaussian Blur setting to only a few pixels. It looks like a small image, so try 2-3 pixels of blur and see if that makes a difference for you.
Thanks for the screenshots.
You may want to convert the Layer to a Smart Object before applying the Filter, that way you can re-edit the Filter settings without unnecessary image degradation.
Personally I would probably go the other way round, create a b/w high-contrast Smart Object-instance and then apply the color via an additional Smart Object-instance (with high saturation etc. and set to Blend Mode Screen for example).
