Filter to enhance the quality of image

[Stephen Liu]

Hi all,

Thanks for your advice.

Tried again.  Re-scan the color film negative on Smartphone with Macro Mode

Start GIMP and convert the image to positive and crop it.

The image seems more clear.  But still I couldn't adjust it to remove the green color

Pls refer to attached photos
photo-1 before adjusting Hue-Chroma
photo-2 after adjusting Hue-Chroma

Edit-1
====
Select
Color -> Auto -> Equalize
It seems the image more clear.  But how to remove the red color ?

Pls refer to Photo-3 (Thumbnail)

Edit-2
====
Again select
Color -> Color Balance

Result - pls refer to Photo-4 (Thumbnail)


Regards
