A flash guide number simply states how far the light will reach on optimal camera settings. A flash with a 120′ guide number is more powerful than a flash with a 60′ guide number. The flash with the higher guide number will be able to light subjects that are farther away from the flash.
In the same way Which is better TTL or manual flash?
Using TTL automatically adjusts the flash output for you as the distance between you and the camera changes. Manual flash is best in scenarios where you want the most control over the light source. It’s also useful if the distance between the subject and the flash doesn’t change rapidly.
Subsequently, Is a Speedlight necessary? An on-camera flash, also known brand-wise as a “speedlight” or “speedlite,” is an indispensible accessory for many photographers; it provides additional light when conditions become too dark to handhold your camera comfortably, allows you to achieve more balanced exposures in daylight, permits freezing of fast-moving …

How long does a camera flash last?
A full-power flash from a modern built-in or hot shoe mounted electronic flash has a typical duration of about 1ms, or a little less, so the minimum possible exposure time for even exposure across the sensor with a full-power flash is about 2.4ms + 1.0 ms = 3.4ms, corresponding to a shutter speed of about 1/290 s.
What is TTL Speedlight?
TTL means Through The Lens metering. … TTL flash uses a series or infrared flash bursts before the flash actually fires. This flash information is returned back to the camera which then adjusts the flash power accordingly to set what it thinks is a well-balanced shot.
What is HSS and TTL?
Using the TTL setting gives you a convenient set it and forget it way of shooting, but there are some limitations including the maximum sync speed. HSS, on the other hand, lets you use your flash at far higher shutter speeds, but with some tradeoffs.
What is S1 and S2 flash?
S1 optical slave mode – fires on the first flash it sees. Used when the source flash is in manual power setting. S2 optical slave mode – fires on the second flash it sees and ignores the pre-flash. Used when the source flash is in E-TTL II mode.
What is TTL and HSS?
If you need HSS (high speed sync) then you want TTL. Manual flash is limited by your camera’s shutter speed. Typically 1/200s or 1/250s. TTL and a compatible camera allow a way around this to shoot at speeds up to 1/8000s. If you’re just starting out HSS is not really something to worry about.
Do I need flash for outdoor photography?
The majority of the time, shooting outdoors doesn’t require firing a flash, even in the shade, as the sun does most of the hard work for you. If you have a subject that you can move, try to get them to change their positioning so that the sun hits them from the side rather than from behind.
Does an external flash make a difference?
A1: An external flash is more powerful for casting light into a far distance, or ensuring sufficient coverage when shooting with an ultra-wide angle length. The built-in flash (also called a pop-up flash) that comes with most cameras, including DSLRs and mirrorless cameras, is indeed very convenient to use.
What type of flash is used in photography?
There are three basic types of camera flashes; on-camera flash, off-camera flash and in-camera flash. On-camera flash is a type of strobe light that connects directly with the camera, though they can also be used as off-camera flashes. The on-camera flash uses a self-contained power supply.
Do you need an external flash for DSLR?
Outdoors flash isn’t as essential. Its good for backlight subjects and can be used to create interesting effects, stop motion in less than great light outdoors, but the range of the light is rather limited. You don’t NEED and external flash but if you want your images to stand out you will probably want one.
What is a bounce flash?
Bounce flash photography is the use of an external flash unit (also known as hot shoe-mounted flash) to reflect the appropriate amount of light onto your subject so that your shot appears bright and sharp. The Speedlite has a rotatable head that can be adjusted to face a wall or ceiling.
How fast is a Speedlight flash?
In general, the flash duration on most speedlights is between 1/400 at full power, and 1/20,000 at low power. This trend is reversed on many studio strobes, which have a shorter flash duration at higher power than at partial power.
Do flashes burn out?
If you shoot events, where you need to take repeated shots with your on-camera flash, they do take a beating and even risk even burning out. …

What is Ettl vs TTL?
Original TTL flashes read the exposure of the overall image straight from the camera’s built-in exposure meter and set the flash strength off of that reading. By contrast, ETTL first fires a few flash bursts to read the exposure while the flash is lighting up the subject.
What is flash HSS?
High Speed Synchronization (HSS) is a function that allows the camera to use fast shutter speeds with an external flash. Cameras have a limited flash sync speed; this means the fastest shutter speed that can be used with a built-in flash is generally 1/125 to 1/250 second depending on the camera.
What is E TTL II?
E-TTL was originally introduced in 1995, then updated in 2004 to E-TTL II, which is the current system. The flash system shares the light sensors in the camera’s viewfinder which are also used for evaluative metering of the ambient light. As the shutter button is pressed, an ambient light reading is taken.
What is HSS Nikon?
Using high speed sync mode with your Nikon DSLR (D7000 series and above) and Nikon Speedlight (SB-500 and up) allows you to synchronize the flash to shutter speeds all the way up to the highest speed the camera is capable of.
