Let’s be honest: you can have the most expensive camera in the world, maybe you even snagged that shiny new Nikon Z6 III or a Sony A7 IV, but if your lighting is whack, your photos are going to look, well, whack.
Lighting is the "secret sauce" of photography. It’s what separates a professional portrait from a "my cousin took this in the basement" snapshot. But here’s the good news: lighting isn’t some dark magic that takes decades to master. Most of the time, the difference between a mediocre shot and a masterpiece comes down to avoiding a few common pitfalls.
At Shut Your Aperture, we see these mistakes all the time. Whether you’re shooting in a high-end space like Edin Studios or you're working out of your garage, these errors are universal.
Here are the 7 most common portrait lighting mistakes you’re probably making right now and, more importantly, how to fix them faster than you can click a shutter.
1. The "Horror Movie" Mistake: Main Light Too Low
We’ve all done it. You’re setting up your lights, and you place your softbox or umbrella at chest level because it’s easier to reach. The result? You’ve just turned your beautiful model into a campfire ghost story.
When the main light source is positioned too low, it casts shadows upward. This is naturally unsettling to the human eye because, in nature, light almost always comes from above (the sun, ceiling lights, etc.). Under-lighting makes the nose look massive and casts weird shadows on the forehead.
The Fix:
Raise that light! As a general rule of thumb, your main light should be positioned about 45 degrees upward from the subject’s nose. This creates natural-looking shadows that define the jawline and the cheekbones.

2. The "Raccoon Eyes" Mistake: Main Light Too High
On the flip side, we have the "overhead sun" problem. If you raise your light too high, directly above the subject's head, you’re going to run into the dreaded Raccoon Eye syndrome.
When the light is too high, the brow bone casts a deep shadow over the eye sockets. You lose the "sparkle" in the eyes, also known as catchlights. Without catchlights, the subject's eyes look flat, dark, and honestly, a little bit dead inside. It’s hard to sell a portrait when your subject looks like they haven’t slept since 2004.
The Fix:
Bring the light down until you see those beautiful catchlights appear in the eyes. Usually, aim for the "10 o'clock" or "2 o'clock" position in the pupil. If you’re struggling with harsh shadows even at the right height, consider adding a reflector under the chin to bounce some of that light back up. This is a classic trick used in fine art photography to create a soft, ethereal look.
3. The Fill Light Identity Crisis
The fill light is supposed to be the "supportive best friend" of the main light. Its only job is to soften the shadows created by the key light. However, many photographers make one of two mistakes: they either make the fill light too bright (killing all depth) or they put it in a weird spot that creates "double catchlights."
If your fill light is the same power as your main light, your subject will look flat. You’ll lose the contouring of the face, and they’ll look like a cardboard cutout.
The Fix:
Keep the ratio in mind. Your fill light should almost always be lower power than your main light. A good starting point is a 2:1 or 3:1 ratio. Also, try to place your fill light close to the camera axis. This ensures that it fills the shadows the camera actually sees without creating a second set of distracting shadows.

4. The "Nose Light" Disaster (Kicker Misplacement)
We all love a good rim light (or separation light). It’s that light placed behind the subject that gives their hair a glow and separates them from the background. It’s the "pro" touch. But there is a very fine line between a beautiful rim light and the accidental "nose light."
This happens when you place your separation light too far forward. Instead of just catching the edge of the hair and shoulder, the light wraps around and hits the tip of the subject's nose. Since the nose is the closest thing to the camera, that bright spot of light becomes the first thing the viewer looks at. Not exactly flattering.
The Fix:
Move your kicker/rim light further back behind the subject. It should "graze" the side of the head, not illuminate the face. A good trick is to use a grid or a "snoot" on your backlights to keep the beam narrow and controlled. This prevents light spill from ruining your shot.

5. Overexposed Separation Lights
Digital sensors are amazing, but they absolutely hate "blown out" highlights. A common mistake is cranking the power on the hair light or background light until it’s a pure white blob.
When you overexpose the separation light, you lose all the texture in the hair. If your subject is blonde, their hair will look like a glowing neon sign. If they’re bald… well, you’ve just created a solar flare on their scalp.
The Fix:
Check your histogram! Or better yet, use the "blinkies" (highlight alert) on your camera. Your separation light should be just bright enough to define the edge, not so bright that it loses detail. If you find the light is still too harsh, try softening it with a small diffuser. Sometimes less is more. You can see how Edin Chavez handles subtle separation in his personal work over at blog.edinchavez.com.
6. The "Mystery Flare" from Backlighting
Backlighting is gorgeous, but it’s a double-edged sword. If your light source is pointing even slightly toward your lens, you’re going to get lens flare. Sometimes flare is cool and "vintage," but usually, it just results in a loss of contrast and a muddy-looking image.
This is especially common when you're trying to get that "sun-drenched" look or using a bright background light in a small studio space.
The Fix:
Use a lens hood, always. If the hood isn't enough, you might need to "flag" your light. This is just a fancy way of saying "put a piece of cardboard between the light and your lens." You want the light to hit the subject, but not your glass. If you do end up with some minor flare or contrast issues, you can often fix them in post-processing using Luminar. Its AI-powered tools are incredible for restoring contrast and cleaning up "hazy" shots.
7. The Distracting, Blown-Out Background
Unless you are specifically going for a "high-key" look (where everything is white), having a background that is brighter than your subject is a major mistake. The human eye is naturally drawn to the brightest part of an image. If your background is a glowing white mess, no one is going to look at your subject’s face.
This often happens in small rooms where light bounces off the walls and hits the background, or when the background light is simply set to a higher power than the main light.
The Fix:
Use the Inverse Square Law to your advantage. Move your subject further away from the background. This allows the light hitting the subject to "fall off" before it hits the wall behind them. You can also use "v-flats" or black foam boards to block light from hitting the background.
If you’ve already taken the shot and the background is a bit too busy or bright, don’t panic. You can use our Ultimate Lightroom Preset Collection to quickly pull down those highlights and bring the focus back to your subject.
Bonus Tip: The "Fix it in Post" Myth
We’ve all said it: "I’ll just fix it in Lightroom." While tools like Luminar and Lightroom are powerful, they can't recreate light that wasn't there. If you have no catchlights, "painting" them in usually looks fake. If you have deep shadows under the nose, brightening them often introduces a ton of digital noise.
The goal is to get it 90% right in the camera. Then, use presets to add that final 10% of polish. For example, if you're doing professional headshots or real estate portraits, using a dedicated Real Estate Lightroom Preset System can help balance the indoor lighting with outdoor window light, but it only works if your base exposure is solid.
Practice Makes… Better
The best way to stop making these mistakes is to experiment. Grab a friend (or a mannequin head if you're lonely) and move your lights around. See what happens when the light is too high. See what happens when you move the kicker light too far forward.
Once you understand why these mistakes happen, you’ll start spotting them before you even press the shutter.

Lighting is a journey, not a destination. Even the pros at Shut Your Aperture are constantly learning new ways to shape and bend light. The key is to keep shooting, keep failing, and keep fixing.
