PhotoFiltre

To start on, we will do a simple partial de-saturation

1. Open the picture and correct it if necessary.

2. Activate the polygon tool and outline the object or the part you wish to keep in colour.




3. Do Selection / Invert selection ... We will then work on the remainder part. (wich will be converted in grey tones)



4. To de-saturate, eigther you do Filter / Aged effect / Black and white,
or you go to Ajust / Hue - saturation and set saturation to minus -100%

The de-saturation is done.

To strengthen a little the black colour, you can do Ajust / More shadows ... There i have done twice.




Eigther you call it quits, the de-saturation is done and you can do Selection / Hide Selection, or you can play on the colour ( from the leaf, here)

To do that, go on Selection / Invert selection to work on the leaf to your liking (by example, decrease saturation : Adjust / Hue - saturation)

There i have plaid to grow old a little the picture, i'm been staid on the selection of the black and white :

Go to Adjust / Colour balance and set Cyan 15%, Yellow minus -10% (as you likie it)







You can also add a mask

Do Selection / Hide selection and then i have applied the mask Flame
Filter/Photomasque / Flame





FINAL RESULT :
