How to add Light to a Photograph
In this tutorial, I’ll show you how to add lights, rim lights, flood lights and warm sunlight to a photo using Lightroom. If you don’t use Lightroom, this works identical in Photoshop Camera Raw. The develop module in Lightroom shares the same tools as Camera Raw.
There are 4 steps to this tutorial, in each we will be using different masking tools in Lightroom and camera raw. By the time you finish this tutorial, you will have a better understanding of how all the masking tools work together. This tutorial idea came about as I am working on a comprehensive course on Adobe Camera RAW. By the time you read this, the course may well be ready under the Premium Tutorials link (2nd 1/2 of Feb 2023).
Part 1. Adjusting the background
If you look at this image, the background is a lot brighter and warmer than the foreground.
The first step is to push the highlights to the left, this will darken down the bright area
Push the Shadows to the right to brighten the dark areas.
Now we want to even out the color.
Click on Mask and Background
Everything except our subject is selected. We want to use different settings on our model.
I also want to exclude the sunlit areas from the selection
Click on Subtract>Brush
As we paint with the brush we can remove areas from our mask. Watch the video above to see this in action and how I got a perfect edge on the posts
To even out the lighting, move the temperature slider to the right to match the background better.
Also move the texture slider to the right to enhance the texture in the wood. (This is why we didn’t include the model in this selection, you pretty much never want to add texture to skin).
Let’ Adjust the basic settings on the model
Click the + Create New Mask
Choose select subject
Our model is selected
Increase the Temp to warm up her skin tones
Play with exposure and reduce contrast a little bit.
Time to add the RIM light in Lightroom
We are also going to step away from working with global light (across large areas). We will add local light (selected areas).
You are going to learn how to use intersect to make quick and easy rim lights.
Intersect will only apply adjustments to where 2 tools or masks overlap.
Hold down Alt/Option in Lightroom (Shift in Camera RAW) to turn the Add and subtract buttons into an intersect button.
When you start to paint with the brush you will see that only the overlapping areas will receive a mask. This is nice because you don’t have to worry about going over the edges of the model
I turned the exposure up on the settings, this will lighten the areas we are painting.
In my mind, the light source is coming from our right (Camera Right) and parallel or slightly behind our model. This where I would position a light if I were going for this effect.
I also would put a reflector to the left and behind the model, to bounce some light to get a bit of a rim on the camera left side.
With the lighting direction in mind, paint around the rim and surfaces like her arm that would be facing the light source.
I’m also adding some light on her face. Be careful to add most of the light to camera right, and not too much on the left (where you see my cursor in the image), which would be in a bit of shadow.
Let’s cast a beam of light.
If I had a light source on the right, it would cast a beam of light, let’s add it now.
Choose mask + Objects. We will use the amazing object selection.
Paint over the area you want to select.
The adobe magic will automagically make a mask over the area that you want to select.
If you want to add to the selection, choose Add>Objects on the mask
Painting a little bit on the left. We want to let a little light spill behind the model to the left.
Choose Intersect>Brush (like we did before)
Paint onto the deck to the right of the model. Let a little light come behind her and to the right (Looking at it now, I probably made that bit of light too strong. Just as well this is just a tutorial and not a masterpiece).
Also be sure to hit the right side of the columns with a little light too.
And thats how you can relight a scene in Lightroom or camera RAW
Here is before
and after (I removed the light behind the model left).
