Correcting the light leak in color channels

- In this lesson we'll be correcting…the light leak in the color channels.…The image has a very nasty light leak…from the left to the right,…and it's faded across the middle here, graduated blend.…So the best way to tackle that is…in the channels and the red channel.…We can see that the red channel…is where the red is obviously faded.…We can see the opposing red up here in the RGB.…What we need to do is increase the contrast…in the red channel, and the shadows and the highlights…so we can counteract the red fade in the RGB.…So keeping the red channel selected,…but selecting the eye icon in the RGB…so we can keep an eye on what's going on…in the main image, we can still work in the reds.…

And selecting our graduated red blend…with the quick mask tool,…and using the graduated fill tool…with black as a foreground and white as a background…in this standard blend mode,…we can make a selection.…I'm going to start with quite a wide catchment…across here, because the reds do fade…right across here, possibly up to the edge of this pillar.…
