Hello,

I have taken photos of some cars, and although it was a cloudy day,
there are shadows and highlights.

What is the practical way of removing shadows/highlights in gimp ?

Thanks in advance,

dev.

Little Ink Pot do a wonderful PS plugin called Xpose

It does not remove highlights or shadows but allows you to work on them
directly

I don't know if there is a similar tool for The Gimp

Hi,

Wouldn't you be able to use the histogram or one of the other tolls that
use the chart to slide the black and white pointers more towards the
center and help with this? I haven't tried this myself, but it might
work. Hope it works for you.

Sorry, that should be tools not tolls in the first sentence. Spell
checking only works if the word you misspelled is not itself a valid word.

(define (script-fu-popraw-cienie image drawable)

(let* ((shadow-layer 0))

; Create new layer and add to the image

(set! shadow-layer (car (gimp-layer-copy drawable 1)))
(gimp-image-add-layer image shadow-layer -1)

(gimp-desaturate shadow-layer)
(gimp-invert shadow-layer)
(gimp-layer-set-mode shadow-layer 5)
(plug-in-gauss-iir2 1 image shadow-layer 25 25)
(set! filename (car (gimp-image-get-filename image)))

(gimp-displays-flush)))

(script-fu-register "script-fu-popraw-cienie"
;image
_"<Image>/Script-Fu/Moje/Popraw cienie"
"Poprawia cienie na fotografiach"

Try creating a duplicate layer (or layers if necessary) and set the mode to
Screen. Adjust the Opacity as required. I've found this method to work quite
well.
