In one of our original photoshop lessons, we were taught how to change and mask the colour of an object, in this case a mini-car.
In order to do this, we selected the colour we wanted and painted it over the car using the lasso tool to select what we wanted coloured, and then we clicked on the tool over the layers tab called “colour”. This tool blended the colours we had chosen with the car.
However, to do the non-destructive version of this, we created a new layer and used the mask tool to create a 2nd version of the mini car, and then we coloured it. This way we could make a mistake with a tool and then correct it afterwards without ruining the photo we were creating.
