Grainy old B&W Post card improvement

[Grubs]

Hi, I have purchased a couple of old, 3.5"x 4.5", black and white post cards which I want to fix and print larger pictures from. Has anyone any experience or ideas on how I can reduce the amount of grainyness in the original picture so that it isn't as noticeable when enlarged?  I have done a 1200dpi scan of the image to a Jpeg file.

Thanks

Hi Grubs,

Welcome to the forums

It sounds as though you're looking for Noise Reduction, you can see this is action in the tutorial below -

If this doesn't quite resolve the 'grainyness', could you please provide a sample of your scanned image? Thanks in advance!

Hi Dan,

Thanks for your reply.  I had tried using the Noise reduction technique but was trying to apply it as a live filter in the Photo Persona which wasn't working.  Done it now in the Develop Persona directly on the image and it works.

I did try to upload the file for interest, but without success,  Got and error triangle and -200 if that means anything

Thanks again for your help.

Glad to hear it, no problem at all!

That usually indicates the physical pixel size of the file is too large, I believe the limit for users is around 3000px x 3000px - but if you have resolved this issue then there's no need to post it here
