Changing colours of Dandelions

[KatieDalgleish]

Hi Damien, can you teach me how to change the yellow dandelions to white without changing the green grass? Thank you.

[Damien Symonds]

Before we get to that, can I ask why there's a weird line over here?

[KatieDalgleish]

Its a composite, I will fix that.

[Damien Symonds]

Ok, cool.

Is this what you wanted?

[KatieDalgleish]

Absolutely! That's perfect

 

[Damien Symonds]

Ok, great.

So, first add a Channel Mixer layer, hit the "Monochrome" checkbox, then enter +100, 0, 0, 0 for the four fields.  This will turn the photo black and white.  Immediately invert the mask to black.

Then add a Levels layer, and clip it to the Channel Mixer layer.  Enter these values:

• Red channel 0/0.80/255 and 25/255
• Green channel 0/0.80/255 and 60/255
• Blue channel 40/0.55.255 and 0/255

Then return to the mask of the CM layer and gently paint over the yellow flowers. The beauty of this method is that you don't need any particular precision - just paint blobs on the areas of yellow.  The only places you'll need precision are where the yellow flowers are near the legs and stuff.

Thank you so so much. That worked perfectly!

[Damien Symonds]

You're welcome.

Please consider the Channel Mixer Class.  It will blow your mind.
