Lots of noise and loss of detail

Hi

First post here, a great forum that I wish I had found before. I have already learnt a load of new stuff in the last day by having a read.
I have one image that has been giving me problems for the last few days and I would greatly appreciate any advice or ideas. I could try to describe all of the problems but it is best if you have a look and see for yourself as there are quite a few.
I would ideally like to reduce the noise and try to bring out what detail there is.
The photo is coming up for a 100 years old so its not doing badly, but I am really at a loss on where to start with this one.

Many thanks

Tim

Re: Lots of noise and loss of detail

Tim,
Welcome to RP
Here is another 2 minute start.
Ran it thru Noiseware first to soften it up. Then do a levels adjust and clip each channel separately to extract whatever detail you can. This followed by a curve adj layer using an S curve to increease the mid tone contrast.
From here converted to grayscale.
If you take a good high resolution scan with a scanner that has a high dynamic range value, you should be able to get a good working image that you could do some fine cloning and touch up. I would also replace the background.
Good luck with the restore.Regards, Murray

Hi

Thanks for having a look at this image. I like what you have done, enhancing the blacks certainly helps. The problem that I have found is that what ever I do seems to enhance the noise as well.
I will have a look for the noiseware plugin you mentioned.

Many Thanks

Tim

Re: Lots of noise and loss of detail

Murray that looks very good for a 2 minute start.
You have mentioned some techniques that I will go and have a read up on and then have a play with.
I do have an old but decent epson gt-12000 scanner so getting a good first scan should not be a problem, cloning and touching up is something that I am quite confidant with.
I agree that replacing the background is a good idea, I had not given that a try.

thanks

Tim

Re: Lots of noise and loss of detail

i am not sure exactly but i believe it is similar to the channel mixer but it allows you to chose from different blending modes ..... i just used the default its set to multiply there are other options to choose from in the apply image window...

Re: Lots of noise and loss of detail

Hi Craig,
The Apply Image command allows you to combine and blend individual channels in the same way that you can combine and blend layers. Except it adds some extrat dimensions of power and flexibility. There are blend modes available in the dialog box for Apply Image, which are not avail with layers (like Add and Subtract). There are also check boxes which allow you to invert the layer before applying it. Finally there is a check box that allows the Application of a layer through a mask and that mask can be any channel in any open image and blended in any blending mode as well as invert the mask.
All that being said though, the default settings basically take the channel that is currently selected and applies it to itself in Multiply blend mode. Therefore what Unimatrix has effectively done is overlayed the R onto itself with Multiply blend mode, thereby restoring some density.
Regards, Murray
