I hadn’t intended for this to be a full-blown article as I thought the topic of double-shadows was brief at best. As it turns out, there were a lot of questions about the double-shadows present in some hard-light portraits and if you’re not familiar with what I mean by that, I apologise in advance.
I’m apologising as it’s one of those things you simply cannot unsee once you’ve seen it and once you’ve seen it, I promise you’ll start seeing it everywhere.
What are Double-Shadows?
We often see the double shadow in modern flash photography and it’s the apparent duplication of a shadow, typically seen on a plain background when the subject is lit with a hard light and positioned next to it.
IMPORTANT: I want to be abundantly clear here; I am by no means ‘calling out’ the photographers who took the above images. I do not know how long they had to photograph these subjects, what conditions they had to photograph these subjects under and I also don’t know what kit they had available to photograph these subjects with. Photography and art in general, is extremely subjective and the following article is intended to provide you with options not ‘improvements’. My intention here is to show what is causing the effect in question and then to provide you with alternatives if you prefer them.
What Causes Double-Shadows?
As I mentioned, the double-shadow look is often found in modern flash photography due to some of the modern kit we use. The often black and white, contrasty, single-light portraits are usually taken with a single strobe and reflector dish and this is where the look originates.
The flash-tube itself will cast a shadow from the subject, but that same flash is also being bounced around a typically very reflective reflector dish. This reflective dish will then also cast a shadow from the subject and this is where the double-shadow comes from.
In reality, there can be more than 2 shadows and there are often 3 due to both sides of the dish as well as the bulb itself casting a separate shadow.
This is a very extreme case of course, but it does show you just how visually busy a single light shot can become if left unchecked. Plus, don’t forget I’m using a white wall as a clear way of showing this effect. This double and even triple shadow effect is still happening on all the shadows in your shot, including the ones on your subjects face like nose shadows.
How can we Fix/Eliminate Double-Shadows?
As I’m sure you’re aware by now, I am choosing my words carefully as although I’m certainly not saying I’m correct in wanting to remove these multiple shadows, I personally do not like the look they provide. Much of photography is about removing as much as possible whilst not taking away from your intended message. I see the extra shadows as distracting and I try to avoid causing them in my photos. Below, I will show you some of the ways in which you can avoid this look if you wish to eliminate the double-shadow look too.
As a baseline for this test, I’ll show you what the bare reflector dish looks like on our ‘subject’ against the wall.
Open Reflector Dish
As you can clearly see in the example image above, whenever we use an open dish like this, the double and even triple shadows start to show themselves.
Reflector Dish with Diffusion Gel
One of the simplest fixes for the double-shadow is to add a diffusion gel to your light. The light itself is still producing a hard light due to it remaining the same apparent size in relation to the subject, but the diffusion gel has now unified those multiple shadows into one single shadow. This is not ideal of course as that diffusion can spread light around the room and bounce back into the shadow reducing its density, but flags and negative-fills can help with that if needed. The diffusion gel is a quick fix if you don’t have alternative modifiers on hand and you see the double-shadow being an issue.
The Fresnel
I mentioned a couple of times above that this double-shadow look is a product of modern flash photography. One of the reasons for that is many of us no longer use Fresnel lights. Years ago, hot-lights or tungsten studio lights were nearly all Fresnels and due to their lens design, their collimated light means they are not bouncing their light around a dish before it reaches the subject. As you can see from the example above, the resulting shadow is beautifully clean and this Fresnel is what many professionals would typically use if they were after that true one-light, contrasty black-and-white look. If you’ve never used one, I’d encourage you to test one out. If you can’t get your hands on one of the originals, many companies now make modifier attachments for their lights instead. I would urge you to test them first though as some of their results can vary wildly and also be very wary of the smaller Fresnel modifiers.
The Optical Snoot
The Optical Snoot is a very affordable way to produce some very hard-light shots. As you may have noticed, the Optical Snoot utilises a camera lens on the front of this modifier to quite literally focus the beam of light. This means you get zero additional shadows and although that sounds good, this very strong and crisp light may be a little too much for some.
The Spotlight
Long-time readers will now know that I love this thing. I used the Optical Snoot for many years before the Spotlight, but once you try this bigger brother, there is no way you’re going back. The Spotlight is a purpose-built modifier, meaning it comes with its own very large and very bright lens on the front. This minimises light drop-off as well as nearly completely eliminating any vignetting towards the edge of this light. If you’re looking for a large and very even coverage of hard-light, the Spotlight wins every time. Again, this far harder light may be too much for a simple one-light portrait.
In Conclusion
If I’m using hard-lights on set, this double-shadow effect is something I do my best to keep an eye on and avoid at all costs. Your mileage may vary of course and if you choose to remove or reduce them, you have a few options to do so.
The basic single open dish reflector with diffusion gel attached is the easier solution. Just watch that diffused light isn’t taking away too much shadow density as it spreads around the room.
The Optical Snoot and Spotlight are of course excellent ways to shoot hard light, but they are EXTREME hard-lights and they may not be very forgiving on your subject.
If you want to shoot this type of single, hard-lit portrait, it’s tough to recommend anything other than a Fresnel. This is what portrait professionals have used for decades and they are still regularly used in TV and Cinema today for their strong yet flattering light. If you’ve not tried one and like the low-key look, you need to remedy that as soon as possible. Just be prepared to fall in love with them…. and then fall out of love with their price!
Lastly, I know I said there are no right and wrongs in photography (you knew this was coming), but at the very least, please avoid using Snoots or Honeycombs (Grids) as a single hard key-light on your subject. You can use them as hair lights, but never as a key due to their awful light quality.
Closing Comments
I’d put good money on you, dear reader, being a proficient photographer, after all, if you’re still reading this, you’re someone who’s looking beyond the typical photography articles and videos. At this stage you’re not looking for the ‘5 Life Changing Lighting Setups’, you’re looking for those rare morsels of knowledge to help refine an already firm understanding of lighting and this refinement of hard light outlined above, is absolutely one of those morsels.
The longer you’re a photographer, the more you realise that every photo is just about a lot of little things adding up to make a big impact and this is very apparent to those of us who have to build our lighting from the ground up on set or in a studio. Paying attention to these little, seemingly unimportant aspects of your image like double-shadows, all add up and it’s this part of the process that many aspiring photographers struggle with. How do we take our images from good to great (subjectively of course)? Typically, it’s by paying attention to all of the little things many overlook in an image and double-shadows is one small, but important part of that…. for me.
