Re: Better way to denoise?

Ok - that noise is honestly like noting I've ever had to work with before. Your method of selecting color ranges (CS4?) and then bringing them into line, may actually be one of the few ways to do it.

The way I would work on this is to make up a series of automated (action based) processes - and then mask them in. Takes out a lot of the labor this way. May be what your doing already. Calculations (probably multiplying channels together) to fill in the broken areas is another possibility. There's some very odd compression method going on in that mobile phone, what type was it? maybe its damaged, or old

Short answer.. NOOOOO! Quality SUCKS!!! But is more recognizable than before.. but still terrible!!!

Tell your client that OlBaldy said to take that Phone cam and stick it up his .... errrrr, I meant to say... throw it away... there are too many other good, small, shirtpocket cams available for anyone to be using a phone cam.. and if he/she is local... go and re-shoot it for them! It would be much quicker and a whole lot less of a pain!

Good Luck!!

Yes, agreed. It's just a quick example to illustrate the noise reduction "look" of this software. I applied it globally in the first example, and it certainly has a softening effect at the strength I used it at.

Of course you can apply Neat Image in other more localized ways to avoid your edges and key elements from blurring. However, as others suggest, you've got some nasty noise there and perhaps a cleaner capture is in order.

Re: Better way to denoise?

Well, I had to have a try at it also. I decided to use tools within PS only.

1. dust & scratches, 3, 15;
2. copy;
3. reduce noise, red channel only, 10, 5.

It's not bad and certainly could save some time if used with some masking, then the other techniques listed by yourself or others.

Best of luck with those !

Re: Better way to denoise?

If you can get it close enough to where TommyO got it, you could then colorize it in color blening mode to finnish it off. Once you colorize, there could be some white spots... clean them up by making a duplicate of the colorized layer then set it to overlay blending mode. Use blend if to protect the blacks.

Another thought,

Re: Better way to denoise?

I know it's an older post. but I got intrigued with the challenge! Anyway this is my attempt. Took me 10-12 min with experimenting! If this post is still a live and if somebody is interested in my method, let me know!

Umm, I read through this thread and see Isedo did not let us know how his finished results came out. Alas he never...

Re: Better way to denoise?

Well since somebody made a reply, here is how I did it:

First I used external filter: PictureCode Noise Ninja v2.3.2
Than I fixed some small detail with simple cloning, and made another pass with the same filter, but this time selectively (Mostly on the red surface). Than I applied Shadows/Highlight filter to bring back some detail in the face. This was done selectivly, again with masking. A bit more cloning, and finaly I applied Median filter to smooth outh the evan surfices. That too was selectivley applied! And that's it!

P.S.
Depending on I image but with some actions I think it could be done in about 3-5 min per image.
