Light Modifiers - How and Why We Use Them
Softboxes, reflector dishes, umbrellas and beauty dishes are just some of the modifiers that we have available to us as photographers to attach to our lighting to change the way it works for us. In this article I will go through the basics of modifiers and the how and why they are used. Before we talk about actual modifiers, we perhaps need to check that we totally understand how light is affected by simple rules when it comes to the quality of the light. Now, the word quality is an interesting one. What we mean by quality and the quality of light needed for one situation may be different to another situation. When I discuss quality of light to my mentoring students, I usually split it into two main characteristics with another secondary one as well. The first thing I talk about is hardness of the light. This relates to the edge of the shadow and how that presents itself. If the light source is small relative to the subject, then the edge of the shadow will be a more solid line, and clearly defined so we call that light “hard”. If the shadow is diffuse at its edge due to the light source being large compared to the subject then the light is usually referred to as “soft”. Obviously there are different levels of hardness, all dependant upon the light size to the subject. The next characteristic I talk about is contrast, which relates to the difference in stops between the highlight side and the shadow side in a portrait. The bigger the difference, the more contrast there is. Now people often call the combination of contrast and hardness as harsh light but contrast is often influenced by light position and closeness to subject and a little by the modifier. You can have soft light that is both contrasty or not and hard light that is also contrasty or not, all depends on positions and the modifier. The third characteristic that modifiers affect is the specularity or shininess of the highlights. In simple terms the lining of the modifier if silver will give off shinier highlights than if it is matt white. What modifiers should you use?
Bare Flash
The design of most studio lights is to use a round flash tube to throw the light as evenly as possible in all directions in front of the head. This is great as it helps get it more evenly spread but a nightmare to control as it does indeed go everywhere.So, bare bulb has the odd use but generally not what we use as portrait photographers
Reflector Dishes
Next up is reflector dishes. These go from tiny to fair sized. From little five inch spill kills to 18 inch maxi reflectors. They are usually silver on the inside and fit direct to the head with no diffuser, their job is to control the spill of light and funnel it all straight forward. They are very efficient and give great output to the light but unless the largest ones they are small sources and produce very hard light when used in portraiture, Great for putting spots on backgrounds but I would rarely use for normal portraits unless recreating the hard lightlooks of Hollywood in the 30’s and 40’s or punchy fashion images with models. Reflector dishes are great for maximising the power of the light if used with low powered lights.
A beauty dish is a modification of the reflector dish, comes in various sizes and with a central deflector which prevents the flash coming straight out, it hits the deflector then bounces back into the dish to then come forward again. The point of this is to reduce the hot spot in the middle. Used a lot in fashion and beauty photography, they can provide beautiful semi hard light with crisp edges to it. They work well with good make up and clear skin but can show up blemishes and skin defects a lot. For general portraiture I find personally I use mine very little though I know others that do. I prefer, using my Elinchrom system to use a 70cm deep octobox with deflector disc and single layer of diffusion to give a similar but more gentle effect. In short, reflector dishes can be useful but they are hard light unless used really really close with the larger ones.
Softboxes
Softboxes are what most people think of when they thing of modifiers. They come in all shapes and sizes from small to huge, and their purpose is to increase the size of the light source to soften and spread it. The shape affects the spread and the size affects the softness ( though you can make them softer or harder by moving closer or further away). The ones I use the most are large octoboxes and strip boxes. As you can guess, octoboxes are octagonal in shape and strips are long and narrow. The strips allow me to precisely control the spread of the light and prevent spill. The big octobox or similar is a really versatile source. It can be pulled back a little to light a family or big group or brought in really close to get super soft light, bringing it in close makes it bigger relative to the subject and bigger is softer when close.
Umbrellas
Umbrellas come in many sorts, sizes and finishes. They can be “shoot through” where the fabric is diffuse and the flash is fired directly though the umbrella towards the subject and the umbrella acts as a diffuser. The other type is indirect where the flash fires into the umbrella and bounces off the inside before coming back out. They can be white or silver or even gold to give different effects to the light. The silver or gold will give a punchier more specular light. The white inside of a bounced umbrella can be a really useful modifier as it is easy to transport, put up and position. Some come with an outer diffuser which adds another layer of softness due to diffusing the light some more. I use these a lot – in particular the Elinchrom deep white 125cm and outer diffuser. It’s easy to get a beautiful quality of light from it in close to the subject. The only downside to umbrellas at times is they are not as easy to control as a softbox and have more spill. Once mastered they are a great modifier.
How to light this portrait - Location Portrait
How to light location photography – Belfast. This location is Belfast’s oldest bar. I did a quick shoot while over there offering photography training, to do something a little different. the model is from an agency and her styling is her own. This place was DARK , the background exposure is iso 200, f2 at 1/10th of a second. So set up for that to render the bar lights as is and the rest dark. I couldn’t move the customer sat at the table so had to keep those dark. The key light is a studio strobe in a large softbox, feathered to give a gentle loop pattern with the dark wall camera right acting as subtraction to give me modelling and contrast. The glass was added with coke in to give the impression of a drink within the bar and to add a little storytelling and context. The exposure was set at F3.2 which was the lowest I could get from the light and it’s position, this meant that the background went dark and the lamps didn’t over power the scene. You can see other lighting diagrams with explanation on my blog. How to Light Location Photography - how to pose and light this image

How to light this portrait - Maternity
This is the gorgeous Tianna Jarrett-Williams, a fellow photographer, who I kidnapped to demonstrate how to light maternity when there was a training session going on at my studio in Preston, Lancashire. This was created and shot literally in a five minutes. So the how is very simple, feathered 135 octobox as key light, 70 deep box as an accent. The ratio would be smaller one at 1 stop less, in hindsight a 1/3 rd less than that would have been even better. The feathering on the key is to just graze that soft light across the front of the bump and also pick out those gorgeous cheekbones, the accent is to prevent total loss of hair against the dark grey background. Camera height is halfway to prevent any distortion and shot on the 85mm at f5.6, iso 50.

Why I shot it like this
I am going to talk about not just the shot but to the whole final image presentation.
The pose is very simple, the dress was a touch as it was not for maternity, so wouldn’t fasten at the back. This meant I was a little limited as to what I could do. Keeping it very simple with a top and bottom bump hand set up , cheeky angle on the head just looking beyond bump to prevent neck compression then probably said something cheeky to get the expression (Tianna and I are friends so I can get away with it, judge your client before trying it!). The crop is just a simple half length as the dress fit better that way.
SO, into PS after a simple raw conversion and then skin tidy , some dodge and burn to really pop the cheek bones and localised sharpening to bring out the details. Now this dress I have shot probably 20 times and try and make it different so popped it into alien skin to give a colour grading which you see here ( no idea which preset, probably a mix of 2 or 3 ). A vignette was added as I prefer to shoot with a large light source for the quality of light on subject which causes background spill which I can then pull down with a curves vignette. That was the retouch finished but I liked the tones and cohesive nature of this so felt the stroke line and border added to the final presentation, the colours of both are sampled from the image to make the tonal range flow through it all.
That’s it really. A simple but effective shot .

How to use a light meter - video tutorial
In a previous blog post, I explained WHY I use a light meter, and why you should, too. Now I’ll show you exactly how to use a light meter in this video tutorial. If you want to really improve your portrait photography and learn in person, take a look at my upcoming Studio Portraiture WorkshopHow to use a Light Meter
Why Use a Light Meter?
As everyone who has had photography training with me will attest, I am a little obsessed with my light meter. It is one of the most important bits of my kit bag and I would feel lost without it. Let me address the excuses I’ve heard for not using one; I don’t need one. I can judge it in the back of the camera. Digital is free so I just adjust and re shoot until I get it right. Close enough will do, I can fix it in post…
Camera screens are all over the place, I can take the same shot on ten different cameras and review on the screen, they will all be different. Firstly, they are all displaying the embedded jpeg, not the raw file – I assume you are shooting raw so will have applied some processing to the file. Whatever your picture style set up is, will affect the jpeg preview. So, in essence it isn’t accurate. Secondly, everyone has their screen set up differently. My own preference to set my camera screen is to load up an image onto the computer (on a calibrated screen), then pop the card back in the camera and pull it up on screen. I then adjust my screen on the camera brightness until it is as close as I can get it to the calibrated screen. That gets me the best preview I can. The same with the histogram, it is read in the camera from the jpeg so isn’t totally accurate.
Why you should ALWAYS use a light meter in portrait photography
I can use the back of the camera
Digital is free, I’ll fix it later…
Digital is free right? Well, it isn’t going to cost you more to shoot 50 images over ten in money, but it will cost you time. time reviewing, time loading into the computer and time culling, time is money to a professional so it does cost.
Fixing it in post, again, takes time and time is money and secondly, any exposure changes is going to degrade the file, so getting it right in camera is better for the final product, always.
How do you use a light meter?
Ok, so what do you do with it? Once you have your meter, have a read of the manual, learn how to change modes, set shutter and iso. When you have done that, in available light, just point it towards the light source and then press the button. If it doesn’t give you the f stop you want, change shutter speed or iso until it does. Simples.
Using a light meter with a flash
With flash, it’s slightly different. Firstly you set it to flash mode, then on most meters you press the trigger button and it will make the flash sign blink, that means it is ready to receive a flash signal to read. You then point it from subject towards the light and then press the flash trigger. It should then give you a f stop (set iso to what you want and shutter speed on meter to 1/125th of a second). The number it gives you tells you how much light is being measured. You then decide if it is what you want to shoot at. Think of it like a measuring jug. If you say decide you want to shoot at f5.6 and the meter is saying f4, you need to turn the light up until when you test it on the meter it gives 5.6, if it said f8 then it needs turning down, just like filling or emptying a measuring jug.

It helps you to be precise
The meter also allows me to measure individual lights to control the relationship or ratio between them. If I want an accent light to blend seamlessly with my main or key light then it needs to be at least one stop less as light from the rear appears one stop brighter than it really is. Only using the meter can I measure this accurately. It’s this precision I love the meter for.
Last reason I like it is that it makes me look professional. I often get asked what it is with clients, I tell them and show them what it does, they understand then that I care about precision and getting things right. I also, as an educator, often get asked to speak at conferences to train photographers. I love the fact that the meter allows me to, under pressure, set up a lighting set on stage, shoot tethered to the projector and have it straight on screen out of the camera and get it right. It builds people’s confidence in my skillset.
10 Things Your New Photography Studio Needs
Every photography studio is different, some are very clinical, others quirky and some are so homely. How you set yours up depends on how you shoot and who your client is – but there are certain things that I would recommend you have in one. One piece of advice I always give is “buy cheap, buy twice” – if you scrimp in the early days, you’ll end up regretting it and having to replace things. Spend time researching what is the best for your new photography studio, and your kit will last for years.What you need in your photography studio
1. A comfy sitting space for clients
Whether you are having a chat with clients when they arrive in your photography studio, changing set ups or want a space for parents to sit while you are photographing their children, a comfy seating area is so important. Something that is easy to clean when you get children with messy fingers are in the studio is what I would recommend. A small sofa or a couple of chairs is ideal and if you shoot some boudoir, a sofa bed like a click clack style is handy as it can be multi purposed.
2. A drinks station!
A kettle in your photography studio for those of us that like a warm drink (white coffee for me, please!) and always a few bottles of water for you and the clients. A coffee machine is a nice bonus, but I prefer a cafetiere as it takes up less room. De-caff options and fruit teas are very popular, especially if you shoot maternity.
3. Parking or access nearby to parking
Almost all clients unless you are based in a city centre will be travelling by car so somewhere secure and close that they can park is pretty essential. It’s a good idea to provide directions with parking info to your clients ahead of their portrait session – they are more likely to arrive on time that way!
4. Samples of your work
So, so important. Clients buy what they see, so if you want them to buy wall art or albums, make sure you have samples on your wall. BIG as you can get away with is what I would say and only items you want to sell and that compliment your work.
5. Sockets!
No matter how many you have you will need more and always have a couple of extension leads. You need to move your lights around to suit what you are shooting so make it easy for yourself and have places you can plug in.
6. Storage
It doesn’t matter whether you think you won’t use many props in your photography studio, you will accumulate lots of items and they need to go somewhere – not on the floor! Things always look better when they can be put away, so get as much storage as you can fit in without encroaching on your shooting area.
7. Stools and crates or other posing aids
These can transform your images in particular if you shoot groups or families. Find something you like and try and get different sizes, so you have one for every eventuality. My Blessence Props Crates are my most used items after backdrops.
8. Lights and modifiers
Even if you only shoot with one light, get a spare and at least one big modifier and if possible a strip box too. With those two and two lights, you can do so much. Backdrops that suit your style, if you don’t like it, don’t have it. Items like a TriFlection from Click Props are great additions to a studio light set up.
9. Viewing area
Use of a large screen TV or a projector to show the clients their images is a fantastic addition, and a laptop or computer that can link to Youtube or iPlayer can keep young children occupied if you need to work with the adults.
10. Facilities
At some point, someone is going to need the toilet and it is ideal if it’s in the same area so you can keep the flow of the shoot going as well as possible if a toilet trip is needed, a private changing area as well or a suitable screening off portion makes clients feel very comfortable whilst changing. A baby changing mat is a useful addition if you have babies and families visit you, wipes and nappies can be useful to have to hand, too.
Why Choose 1:1 Photography Mentoring
I have been training photographers and offering 1:1 photography mentoring for many years – both professionals and beginners. I am passionate about raising the quality of portrait photography for everyone. If you’re looking for photography mentoring, you’ll find an array of different options available – online workshops, in person small group photography workshops, larger group workshops and 1:1 mentoring. Hopefully I can help you to choose what’s right for you. There is some information here, and on the training page of my website, but do get in touch with me if you’d like to discuss it in person.Why Choose 1:1 Mentoring to improve your Photography
1. Bespoke to you.
Whether you are a complete beginner or a seasoned veteran photographer, you are never finished learning. A 1:1 photography mentoring session with me can be completely bespoke to your needs, what you want to work on and how you learn. Whether you are looking for a day learning about fine art photography, or a half-day in the studio and a half-day editing, or even ongoing support with regular training throughout the year, we can design your photography mentoring to be all about you.
2. In your own space, or in mine
I travel all over the UK and throughout the world to deliver photography training. Coming to you means that you can learn the very best ways to use your props, posing aids, lights and studio space. I can even help you to decide what you may need to buy to add to your studio collection if you want.
If you don’t have a suitable studio then you can come to use mine and I will train you using the very best Elinchrom lighting and modifiers from The Flash Centre, and a fantastic selection of backdrops from Click Backdrops. You can use this knowledge whether you are mobile or use another space to work from.
3. Find or develop your own style
In a workshop, a group of people will inevitably lead to more generic training, whereas a 1:1 means we can concentrate on your own style of photography. Whether you prefer light and airy, vintage, fine art or high key, we can spend a day working carefully on your style of photography.
4. Concentrate on one genre
If there’s something in particular you want to excel in, in a 1:1 mentoring session we can concentrate on the genre you want to specialise in. If you’d like training in boudoir posing and lighting, we can concentrate on that, or if you’d like to work with younger children, then that’s OK too. You’re in charge of your training and I’ll help you with whatever you would like me to!
5. Some things are just better 1:1!
When we are working together for 1:1 photography mentoring, there are some things that we can do better than in a workshop! For example, I can demonstrate a skill, then watch as you try yourself, and make tiny adjustments to show you exactly how to get it right. We can sit together at an editing screen and I can show you the small edits that will make a huge difference to your image. It’s all about you – and how I can best help you to become a better photographer.
