How to Choose Your External Flash for Photography

The ShotVoice Team — Tue, 09 Dec 2025 10:48:15 +0000

When it comes to necessary photography equipment, flash is not always the first thing you think about instinctively. However, it contributes to the success of photos in many ways and not only when used at night. As we will discover together, using flash creates an artificial light, thereby making it possible to take a photo with extra luminosity.

First of all, we will briefly summarize what a flash is and what it is made of. Then, we will be able to compare different flashes in order to select the one that best suits the photographer’s needs. The models differ according to their uses and the device receiving it. Then, we will be able to establish an initial overview serving as a basic guide according to the use we wish to make of a flash.

The Principle of a Camera Flash

The purpose of using a flash is to create a short, but high-powered light to illuminate a scene in which there is no or insufficient natural light. However, the light intensity (calculated in TTL) must be high (whereas only the camera’s battery provides the necessary energy). This is why a flash is called a “flash”: it’s a fast flash of light intense enough to create the desired instant lighting.

Technically, a capacitor charges itself from the electricity of the battery and then promptly “empties” into a transparent flashtube that delivers the light intensity into the environment of the scene.

Compare the Different Types of Flashes

One flash is not necessarily worth another, although light is always light. But the flashes can be differentiated by several characteristics.

1. Measurement of Power

The power of a camera flash is determined according to several criteria:

ISO sensitivity;
light intensity expressed in TTL;
the position of the flash zoom (possibility to synchronize with the zoom focal length);
the guide number (a number equal to the distance multiplied by the focal length), the larger the number the more powerful the flash.

Therefore, the light output of a flash can be broken down into several measurements allowing you to select one flash over another according to your needs.

2. Recycle Time

Although rarely deciding to choose a flash, the recycle time indicates the minimum technical time between two flashes. Often varying between 1/2 second and 7 seconds, it should not be forgotten that the higher the recharging speed of the flash, the more often it can be used over a given period of time. However, pay attention to the battery life of the camera. A model with a rechargeable battery (Godox type) can satisfy regular flash users.

3. Flash Models

There are a few typical models of flashes depending on the way they are positioned in relation to the camera.

The Cobra report flash or flash is usually positioned on the top of the camera. Synchronization is achieved thanks to the compatibility between the flash and the device.
The studio flash is usually plugged into the mains or generator and allows a high flash rate for unmatched light quality.
The ring flash is a flash located on the front of the device. Its mode of operation based on low-power light is intended more for macro subjects or portraits.
The camera’s built-in flash is more limited. However, it is generally sufficient for portraits and also allows the triggering of other flashes (for example, wireless mode).

Variants exist in the middle of these four large families, and each manufacturer (Canon Speedlite, Nikon, Sony, etc.) competes with ingenuity to allow the evolution of the range of flashes of cameras.

The Other Criteria to Be Taken Into Account

Obviously, there are plenty of other features specific to flashes as well as elements that make it possible to choose well. These include, but are not limited to:

an adjustable head allowing to change the angle according to the scenes to be photographed;
the presence of internal and external diffusers (to cover extreme focal lengths and to cover the “flash effect”);
a manual flash trigger for testing, open-flash, or triggering other connected flashes.
etc.

Not all of them are essential, but it is up to each photographer to determine their needs in order to choose their best photo flash.

How to Use an External Flash

The external flash has several operating parameters to meet various needs. Without being able to review them all, let’s discover together the most important ones and what they correspond to:

TTL mode is a mode that requires the device to measure the intensity of the flash through the lens accurately and taking into account the filters placed on the lens;
mode A as “automatic” measures the light intensity on the flash directly and does not take into account the lens filters. This mode is replaced by TTL mode;
M mode for “manual” allows the photographer to manage their own flash (open flash) as well as the light intensity;
Wireless mode allows you to connect and control other flashes through the main flash;
“Video” or “LED” mode allows a less intense but continuous light for making videos (without the quality of “studio” lighting for videos);
Stroboscopic mode is a feature that allows you to emit several flashes of light in one second. It is mainly used for specific subjects and is therefore intended for informed users;
etc.

Once again, manufacturers (Canon, Nikon, Sony, etc.) are redoubling their ingenuity to make it easier for beginners to learn how to use external flashes while allowing more experienced users to make the most of their capabilities.

The Synchronization of an External Flash: an Important Point

Synchronizing the flash with the camera remains an important consideration. Indeed, if the flash occurs before or after the opening of the aperture, it will have been useless. Therefore, the flash must produce its flash at the right time. But what is the right time? Because as soon as we talk about light, we talk in nanoseconds of light propagation while the speed of opening/closing of the shutter is in hundredths of a second, the notion of the right moment constitutes a dilemma.

It is therefore an important criterion that the photographer must know how to master. In the beginning, the automatic mode allows an optimal trigger for a simple photo. But when effects are sought, the situation is different:

long exposure for ambient light;
first or second curtain synchronization;
high-speed synchronization;
etc.

To conclude, the choice of an external flash must force you to ask yourself the right questions. Each photographer (beginner, experienced amateur, professional) will make a different choice among the many options and variants. But most entry-level flashes already offer a number of options that a beginner will take some time to master.

Moreover, the budget to be spent on such equipment is not trivial and it is important to be well informed before making the purchase. Consideration should also be given to ensuring compatibility between the external flash and the camera that will receive it. Then, only practice combined with systematic learning will allow better control of the external flash and the camera.

The Fundamentals of Photography Lighting Solutions

The ShotVoice Team — Wed, 03 Dec 2025 10:58:10 +0000

People often ask what photography equipment is necessary to achieve professional quality photos. We usually think of the camera body and lenses first, but the question of lighting is also important, if not more so.

Indeed, no matter the conditions in which the shots are taken, lighting is one of the key points; it is a powerful tool in photography. At the same time, mastering the settings of the digital camera, especially the manual mode settings, can make a big difference, especially when it comes to light. Explanations.

The Importance of Lighting in Photography

Light is a key factor in the success of a photo. It determines many aspects of a photograph, such as:

brightness and darkness;
tone;
mood;
atmosphere.

That’s why it’s important to know how to handle it. A photographer who knows how to control the light can easily obtain and play with textures and colors.

Lighting in Photography: All Types of Light

Since lighting is one of the most important concepts in photography, it seems essential to explain certain basics with regard to the different types of lighting.

Natural Light vs. Artificial Light

An initial fundamental concept for understanding lighting in photography is the distinction between natural light and artificial light. Natural light is produced by the sun, the moon, the sky. In this case, the lighting is not 100% controlled, since these elements cannot be influenced. Artificial light includes all other light sources such as lamps, flashlights, studio lights, LED lights, etc.

Soft Light vs. Hard Light

Hard light usually creates many dark shadows in a photograph. Hard light sources include daylight sunlight, flash (when used without a diffuser), flashlights, etc. It should be noted that the smaller the light source compared to the subject, the harder it is. Of course, these two types of light have variables in terms of intensity and quality.

Cloudy weather makes it possible to diffuse light naturally. But there are solutions for artificial light sources. Diffusion of hard light results in softer light. For flashes, it is also possible to use clip-on filters, for example.

The Position of the Light

The type of light, but also the position of these lights, contribute to a photographer’s creative process.

Frontal lighting: this is a light illuminating the front of the subject. This type of lighting is uniform and creates what are called flat images. This gives saturated colours and minimizes textures.
Lateral lighting: this is a light illuminating the side of the subject, which produces shadows. This type of lighting is ideal if you want to create a dramatic effect, highlight textures or give a feeling of volume and depth.
Backlighting: in this case, the light is located behind the subject. This type of lighting makes it possible in particular to create silhouettes. The harder the light, the more the silhouette is formed and the more details of the subject or object are lost.

Depending on the position of the light, the characteristics of a photo can completely change. Take the example of golden hour. The sun being very low at this time of day – at sunset or sunrise – its rays pass through much of the earth’s atmosphere before reaching us. This angle completely changes the temperature of the colors to create golden tones. This time of day is particularly appreciated by photographers.

Lighting Solutions in Photography

In photography, there are many solutions for controlling lighting, whether it is natural or artificial light. Here are a few examples.

1. Flash

The flash is an accessory we all know about, yet many people dismiss its use. However, if it is used well, it can achieve very creative results. In addition, the characteristics of the flash can be controlled according to the desired effect. You can adapt the power, intensity, color, quality, direction, etc. Accompanied by the flash, you can very well use diffusion material to soften the shadows.

There are mainly two types of flashes: cobra flashes, also called “speed light” and generally located on the camera, and studio flashes that can be used at a distance.

2. Continuous Lighting

Continuous lighting comes in contrast to direct lighting created by flashes. There are two types, which are:

halogens;
LEDs.

Continuous lighting seems to be the favorite technique of professional photographers, especially because it allows better control of the effect, particularly through better control of the white balance. Indeed, it is easier to make adjustments since we can directly see the lighting effect, unlike flashes. This type of lighting is also essential when you’re not just taking pictures, but also making videos.

3. The Reflector

The reflector is an important tool in photography – especially in portrait and studio photography – that helps control lighting. It does not create the light, but rather corrects it.

The reflector makes it possible to reflect or return the light onto a subject’s face. For example, it can correct shadows on a face during an outdoor session in the middle of the day, or it can prevent a backlight from forming a silhouette. Contrary to popular belief, there is no need to invest in overly expensive products: a poster, a foam board or polystyrene can act as a reflector.

4. The Diffuser

Like the reflector, the diffuser is not a light source, but makes it possible to correct it. The diffuser is a tool used to create softer light, to create less harsh shadows. It redirects the light source for wider and more uniform diffusion, reducing contrast.

5. The Light Box

Light box photography is a technique that was invented for product photography. It is therefore widely used in e-commerce, but can be used for other creative projects. The light box allows you to capture all the details of a subject.

It is a white and smooth material arranged in five panels: the platform, the three vertical sides and the roof. A light source is then placed all around to be inserted into the box, and the white surfaces reflect the object placed in the box. This lighting technique erases the contrast: it should not be used if you are looking for an original or dramatic effect. With a little imagination, it’s also possible to create a light box yourself.

Being aware of light and illumination contributes to the development of a photographic style.

How to Build a Professional Photo Studio at Home

The ShotVoice Team — Mon, 01 Dec 2025 15:04:12 +0000

Photographers who want to take professional photos from home often dream of having a photo studio at home or in a dedicated room.

This requires reflection, the necessary photography equipment and some specific accessories, but it is possible to create your own photo studio.

Of course, it is not enough to place a canvas on a wall and use a light reflector. We must first think about the layout of the space and the type of photo to be taken, then proceed in stages in order to create a photo studio worthy of the name. Here are some practical tips for a creating a personalized and top-quality photo studio at home.

Define the Space Dedicated to the Photo Studio

Generally, it is unwise to consider creating a photo studio in your living room or bedroom. In order for a studio to keep all its promises, be well-set-up and leave enough freedom in the shots, it is advisable to place it in a relatively spacious place where it can remain as it is, without the need to move the equipment. That’s why creating a photo studio in a large office, a garage or another unused room is a great idea.

On the other hand, it is preferable to avoid very bright rooms in which it is not possible to obstruct the daylight (e.g., a veranda). The ideal situation is to have the possibility of using natural light, while also being able to decide to use only artificial lights (room with windows that have curtains and shutters that fully black out the light).

In addition, it is, of course, necessary to think about the space available for taking pictures. When you want to take a photo on one level, for example, you must have sufficient clearance for the shot to be possible. For the photography of small objects or dishes, for example, the space available and the distance are a little less problematic, but you still have to feel comfortable.

Create a Background for Shots

Once you have chosen the room, it’s now time to create a background. It is in front of this background that the photography subject will be positioned. This is why a white background is most often recommended, which will not reflect color on the model or object.

In some cases, you can just use a white wall of the house as a backdrop. Depending on the desired photography style, it is still possible to opt for a colorful wall.

The other option, often preferred, is the use of a fabric background, for example, using a white sheet. It is then necessary to take care to iron it and to keep it taut so that the folds do not appear on the image and do not create undesirable shadows. The advantage with this type of background is that it is washable: at the slightest stain, the sheet can be put in the washing machine, and you will end up with a new background.

Finally, another solution consists of setting up a paper studio background. It exists, of course, in white, but we also find black as well as all kinds of colors, patterns and landscapes to create the photographs you want. The ideal solution is to buy a base in kit form, i.e., with integrated support, so that the base is correctly fixed, easy to move and well tensioned.

Set Up Appropriate Lighting

Lighting work is essential in a photo studio. Many products can be used to achieve the desired brightness and shadows, mostly in the form of flashes, halogen bulbs and LED lights. The choice depends on several criteria that are specific to each photographer, the type of photo they are taking (macro photo, portrait photo, etc.), what they want to bring to light, etc.

The use of natural light is not prohibited, but you must be able to manage and customize the light input and temperature.

To ensure a continuous source of light, bulbs and lamps of all kinds can be used. It is not necessary to have professional equipment. The key is to find lighting that will provide the desired temperature, hue and light intensity.

In the studio, it is not uncommon to also find flashes. In this category, we first find the Cobra flash, which can either be mounted on the camera’s hot shoe, or positioned at a specific place in the studio. In this second case, it is recommended to invest in a remote control to manage it remotely or to trigger it automatically at the time of the shooting.

Thanks to this type of lighting, you can obtain a professional quality image, much better than with the built-in flash of the device. It is also ideal for taking pictures of moving subjects.

Another solution is studio flash. Here, it will be necessary to pay a certain price, because this is professional equipment. Still, it offers great power, much more subtlety and it can even make it possible to do without light modelers, as its features are numerous and the light it gives off is high quality. However, it is more complex to set up and it takes up a lot of space. Photographers who set up a studio in a small space or who have a limited budget, and who know how to use light reflectors, have no real reason to opt for such a product.

Choose Accessories for Playing With the Light

The light in the photo studio depends on the lighting, but not only that. With continuous lighting or a cobra flash, it is essential to have light modifiers. With them, you can do almost anything you want with your lighting sources: dim a light, redirect it, modify the shadows, etc.

These products can take several forms, the best known certainly being the umbrella. But there are other light modifiers available today at affordable prices, such as the folding fabric reflector, the snoot (a tube to be installed on the flash to direct the light), the “honeycomb” grid (which allows you to work on the distribution of the light), and so many others.

It is recommended to get different light moderators, so that you can work with the light as you wish depending on the light sources, the subject, the style of photography, etc.

Think of Practical Accessories for Your Photo Studio

We have so far mentioned rather technical equipment, but to design a photo studio, it is also necessary to be ingenious and have the right equipment to position everything correctly.

The tripod is, of course, one of the most essential pieces of equipment in a photo studio. But other small accessories, which we might tend to forget, are also important. Examples include gaffer tape, clips for hanging up fabric backdrops, flash mounts, equipment storage cabinets, etc.

It is better to anticipate the purchase of these supplies, to avoid substituting them with accessories that could be found at home and that would not do the job perfectly.
