where is soft noise addition control ?

Question

Hi, adding in noise to get a comocolour line to be matching original, all nosie options are far too crystaline and bitty.

see storyboard attached. Just where does one apply the softness of the noise ?

I had to remove a yellow card, then draw in a grey line for the now part removed aerial wire, it needs noise to match the original, I try all noise options, it needs mild coloured noise, but all are far too false, compared to the original.

I have never ever got on with the add noise, far too crude, yet adding solid colour to an image needs noise adding, now with Pshop 2025 I thought there would be better noise, but its no different than 30 yrs ago, yet its a fundamental need. Noise is never as 'bitty' and pixel defined as the noise tool gives.

Cannot blur the image as the line would get destroyed. Add noise needs a noise softness slider, where is it ?

I normally use about 1% luminance gaussian, then 0.5-1 % chroma gaussian - but with gaussian blur about radius 0.15-0.3 after each. Obviously, actual values will vary with resolution and noise level of the original.

That usually matches sensor noise pretty well. Not perfect, it still has a slightly "papery" texture, but good enough for most practical purposes. I also tried Grain in the ACR filter, but that looks distinctly synthetic. This is zoomed to 200%:

I don't do this often enough that I feel I need a dedicated setting for this. I'm OK with knowing it can be done when I need it.
