An Absolute Beginners Guide to Flash on the Fuji X100t

Flash in Street photography is a very useful tool. It creates a certain style of harsh light that has a more gritty feel that suits many styles of street photography. Mark Cohen and bruce guilder are two great example of street photographers who have made great use of flash. But getting into using flash in street photography can be tricky to work out how to use it right. That’s the problem I came across with my Fuji x100t. There was a built in flash but I didn’t know how I should start using it. So I made this guide to help other Fuji x100t users (but I’m sure there will be useful points for other photographers out there who use different cameras).

Why use flash on the Fuji x100t?

Dirty Harry “aka Charalampos Kydonakis” has said that he uses flash because it is the only way for him to control the light on the streets. I think this is probably the best short summary of why you should consider using flash. Admittedly, there are lots of different aspects and effects that you can create via this ability to control light.

Here are some bullet point reasons

  • you can pick out details in shadows, when shooting towards the sun or in high contrast scenes
  • you can shoot at slower apertures and so get more details in focus
  • you can capture an instant even at night
  • flash light is “harsh” not soft and creates a distinct style
  • Flash helps subjects standout from backgrounds
  • you can freeze a subject, while having a blurred background

There are more personal reasons for using flash but these are probably some of the core reasons.

Personally, the second two details appeal to me the most. I want to be able to capture details no matter what time of day. I also quite like the style that flash causes in images but I don’t always like it. Still it is something I’m experimenting with more.

Why you shouldn’t use flash on the fuji x100t

  • you don’t like the harsh light
  • you don’t like the look of the hash flash light
  • you don’t want the attention that flash will draw

These are all valid reasons for not using flash but I would suggest you consider trying flash anyway. Flash does give a very different style and can be very useful to capture photos you can’t get in other ways. It is worth trying and experimenting with anyway.

Different modes of flash

Obviously, there are different types of flashes you can get. These might be built in like the fuji x100t’s flash or an eternal flash that is either

  • in a shoe mount
  • held in a second hand
  • set up on a stand and triggered remotely.

These will create slightly different effects and open up other options. Using off camera flashes allow you to control the direction of the light in a way you can’t with on camera flash. However, that is a topic for another article. The rest of this post is going to be based on on camera flash, in particularly the built in flash for the fuji x100t.

Practical tips to get started

A couple of practical ideas you might want to consider as you begin experimenting with flash. It can be very intimidating to start shooting using flash on strangers at night, drawing a lot of attention and at the same time, not even taking a good photo. So instead, I suggest two ideas.

  • start with friends
  • then use it in daylightBy starting with friends at night, you can work out what is working or not, how bright the flash will be and how obvious you are going to be. The by using it in daylight, you get used to using flash, being noticed when you shoot but also being slightly more discrete than shooting at night.

Activating flash and why your fuji x100t flash might be blocked

I’ve changed my menu options so that my top function key activates and deactivates my flash (switching from forced flash to suppressed flash). You can change flash mode by going into the menu (press the menu button) then scroll to menu 5 and find the flash options there. If you get to this menu and you can’t activate your flash then it is probably because your camera is in silent mode. This stops your shutter making a noise but obviously, if you want it to be silent and not distract anyone then you don’t want a bright flash do you. So make sure that you haven’t got silent mode on if you want to use the flash.


Most modern flashes (especially built in flashes) offer TTL metering. That means it takes the data from your camera’s metering system (be that spot, centre weighted or evaluative) and sets the flash based on that. This is very useful during the daytime and making street portraits, it helps you to focus on composition and just take the picture. However, if the scene is fast moving, you can miss shots or “decisive moments” by the cameras brain taking a bit to long to think through the shot.

Manual settings

However, with the fuji x100t, if you start setting you camera manually, you are going to assist your cameras flash brain. For example. By setting your camera to a fixed iso (maybe ISO 400), aperture (f11) and zone focus. You are now telling your camera what exposure it needs at the right distance (based of iso, aperture and distance). If you take note of the distance of your zone focus, you will be able to freeze your subject, correctly exposed at the right distance. If your subject is closer to the camera, it will be over exposed, if it is further away, it will be under exposed.

What about shutter speed?

Shutter speed will not affect your flashes exposure as the light travels too quickly for it to factor in. Instead, your shutter speed controls the “ambient exposure” and will affect the surroundings of your image.

Flash and the two exposure settings

Unlike natural light photos or shooting in a studio. Out on the streets you have your flash exposure and your ambient exposure. The ambient exposure is what you would see without using the flash, if you didn’t have the flash on, it would take that image. You can therefore workout how the surroundings will look by setting your shutter speed accordingly. It will only affect your ambient exposure while the other settings (iso, aperture, flash strength) will also affect your flash exposure.

This means that during night time you can have a frozen subject up close while the background lights and people swirl. A cool effect that can be overdone.

Flash Exposure compensation

The fuji x100t also has built in exposure compensation, it’s nested a little deep within the settings but it will allow you to adjust your flash settings so if you really wanted, you could have your zone focus and flash exposure position different from each other.

Slow synchro flash on the Fuji x100t

A final feature of note is the slow synchro flash setting. This allows you to fire the flash after the shutter opens. letting in light before firing the flash. This is great for creating a trail with a frozen subject at the end rather than a frozen person and the hint of a ghost moving away from them as you would with a normal flash setting.

Some suggest flash settings for the Fuji x100t in manual

Here are some fun ideas just to get you started with using manual flash on the fuji x100t. These are just something to start with but definitely adjust the settings as you play around. You may prefer a slightly different style.


  • ISO [depends how bright but usually 200–400]
  • F16 [get as much in focus as you can. You can of course go lower if you like]
  • shutter 1/250 [freeze as much as possible. drop down to 30 if you want some blur]

night time

  • ISO 1600, maybe 3200
  • F8–11
  • shutter speed 1/15

What about external flashes?

Of course you can use an external flash, these open up some extra options and have different controls. I’m yet to play with one however I am considering the ef-x20 to add a few extra options to my shooting.
