There was a time when if you wanted to change the colour of an object in a photograph, you had to load up Photoshop in order to do it. But these days, there are a lot more options out there. And now, even Lightroom is getting in on the action, thanks to the recently added AI selection tools that let you target specific subjects within a photograph and do pretty much whatever you want to them.
In this video, Aaron from Phlearn shows us exactly how we can use those AI selection tools to pick out our subject and then isolate the dress they’re wearing to completely change the colour of it, non-destructively, before you’ve even thought about bringing it into Photoshop.
Aaron’s process allows him to select just the dress by using the intelligent AI masking feature to grab the subject and then subtract the human portion of that selection. This leaves him with a new composite mask that just selects the dress. The subtraction side of things isn’t AI-generated, though. It requires a bit of manual work – but it still only takes a couple of seconds.
The subtraction is done here using the colour range. Going by colour range isn’t always going to work, so you may have to use a different method in your own images to refine that subtraction. But in this case, it does a decent job as the skin tones and hair of the subject are very different from the bright vibrant dress. With the final selection made, changing the colour is as easy as dragging around a hue slider.
It’s a great technique for when you need to just quickly change the colour (or anything else) of an object in your scene and the video offers some great tips for working with masks in Lightroom.
