Lines on photograph

[Vco]

Hello!

Wasn't quite sure what to call the problem in this photograph, maybe someone else could tell me.

I've tried many different methods on trying to remove the lines in the photograph and to no success and wondering if anyone else has come across this before and has a better method on removing the type of mutli-coloured crosshatched lines (only way I can describe them lol)

Thanks in advance

HI,

I think it looks like a either a bad scan or a scan from a bad inkjet print.

You can try the Fourrier Transform Filter that works well on repeating pattern (not sure I'll work with this one, since it's not so repeating), you may try the noise reduction filter in Filter> Noise (photoshop) with the tweaking of "reduce color noise"

Others may come with better ideas though...

HTH.

Assuming you cannot see on the surface and the original was a print a dirty or faulty scanner could cause this type of vertical line.

Try scanning again as the attached and then do another scan with the print rotated 90 degrees.

If you get scan lines in both images but running in different directions then scanner is suspect, which could mean lamp or electronics. If the lines run in the same direction relative to the print position then look carefully at the glass and see if it needs cleaning both sides.

If the scan was from a negative or slide then this is either abrasion mark or chemical staining.

In either case trying to remove these will prove very difficult and time consuming.

If you cannot get a better scan then have a play with noise reduction. It may help to minimise the effect. Very quick play with Noiseware on the attached.

EDIT: Just posted before I saw the reply from lurch. I have heard Topaz get good reviews so that might be a better option

Topaz Denoise might work. It has a feature that removes lines caused by noise. I've never tried it though.

Thankyou guys for your input, greatly appreciated - I shall have a look at Topaz denoise and see what happens.
