One row of pixels is recorded when the fluorescent light is on while the next is recorded as the light cycles off. This can produce some obvious bands across your photo. Some funny things happen when using an electronic shutter under fluorescent lighting.įluorescent lights are not continuously “on.” They actually cycle at either 50 or 60 cycles per second, depending on your country’s power grid. – you’d burn it out in no time and whitewash everything! Fluorescent lighting Imagine leaving that light on for 1/10 sec. Speedlights only have one “brightness” the power/exposure of a flash is actually dictated by its burst time, which is typically around 1/400 sec.

Your flash options will most likely be disabled in your camera when the electronic shutter is enabled (as with Fujifilm and Sony mirrorless cameras, for example). Electronic shutter flash limitationsįorget it – you can’t use flash with an electronic shutter, in most cameras, for now.

The homes beyond have a slower relative movement and are thus more vertical. Now here’s what those disadvantages are.Īnother train example of “bent” lines that should be vertical, due to electronic shutter use. Hopefully, the above photo helps you understand what’s happening when the electronic shutter is used. Disadvantages with Electronic Shutter silent shooting Notice the exaggerated diagonals in elements that should be vertical. Lines that should be near vertical are actually very diagonal. It’s a perfect illustration of how the light is recorded one row at a time as this train is moving past at a combined speed of 150+ mph. This is exactly what happened to me, as you can see in this photo. A train passes on parallel tracks going the opposite direction and you take a photo at 1/500 sec.Ī mechanical shutter would show some slight motion blur, kinda like what your eyes register, because the entire image is made in 1/500 sec.īut there’s some serious electronic shutter distortion because the entire process is taking 1/10 sec., not 1/500 sec., when that electronic shutter is used. You’re using the electronic shutter so you don’t advertise all the photos you’re taking. Now imagine that you’re in a fast-moving train. from the beginning of the exposure to the end, dependent on the camera’s processing power. But because each pixel row is turned off & on one row at a time, the entire process can take as much as 1/10 sec. When an electronic shutter is used, each pixel row is exposed to light for that same 1/500 sec. When your shutter speed is 1/500 sec., this entire process happens pretty close to 1/500 sec., only adding the time it takes for those curtains to fly over the shutter. With a mechanical shutter, the sensor stays on and is only exposed to light for the time the curtains are open (your shutter speed). Again, this process happens row-by-row in a cascading manner.Įlectronic shutters turn each pixel row off – on – off – on, one row at a time, exposing each row for the shutter speed time.īut hold on… How much time does it really take? That’s the most simplified way of describing the digital circus happening at the time.

Still pretty damn fast! Electronic shuttersīut technology allows us to manipulate the sensor digitally, something we couldn’t do with film in-camera. On the Fujifilm X-T3, for example, the maximum mechanical shutter speed is 1/8000 sec. The faster the shutter speed the smaller the slit between first and second curtains in a mechanical shutter.ĭue to mechanical limitations, mechanical shutter speeds can only go so fast.
