Q. What is the difference between TTL Triggers and Manual Triggers ?
A.

TTL Radio Triggers are more advanced than Manual Radio Triggers but in order to use TTL Radio Triggers then they need to work alongside compatible TTL flashguns. You can think of TTL Radio Triggers as being the “smartphones” of the photographic world. TTL Radio Triggers are fully automated which means that the photographers do not have to spend their time with regards to setting up their lighting set-ups. This is because with TTL Radio Triggers then the Photographer can now just simply “Plug in and Shoot” with them.

However, lets just say that you were working with Manual Radio Triggers instead, then you will find that you are now spending more time with regards to your lighting set up, you may even find your-self working with the aid of a light meter in order to aid you in the process of working out what aperture it is that you should be dialling into your DSLR with regards to the power settings of your flash. With manual Radio Triggers then they simply just tell your light when to flash and that's it. Manual Radio Triggers can not control the power of your flash where as TTL Radio Triggers can.

Q. What is the difference between a transceiver and a radio trigger ?
A. The difference between a Transceiver and a Radio Trigger is that a Transceiver can either transmit a signal or it can receive a signal. A Radio Trigger Set-Up requires two parts, these are 1) a Transmitter and 2) a Receiver. A Transceiver however has a Transmitter and a Receiver built into it, there for making it a two way system. The main benefits of working with Transceivers is that they can replace either a transmitter or a receiver if one is accidentally broken. However, it must be noted that you need a minimum of two transceivers to work with the system. As you need one to A) Transmit and the other to B) Receive.
Q. My photo is pitch black when I take a photo with Radio Triggers ?
A.

There are a few reasons why you may be experiencing a black screen when you take photographs with Radio Triggers these are. Your Radio Trigger & Receivers or Transceiver are in fact switched off and not switched on when you in fact think that they are switched on. Please check to ensure that your Radio Triggers or Transceivers are actually switched on at their power switch. Yes, this can be pretty embarrassing we know.

The problem may be a sync-speed issue, if you shoot your shutter faster than your cameras actual “Sync Speed” or faster than your Radio Triggers actual “Sync Speed” then you will of course experience a black screen or even black bands within your photographs. For example if your cameras “Sync Speed” is 250th second then you can not, shoot your DSLR faster than that shutter speed with out getting a black screen / black banding with in your photographs. Please check both your Cameras Manual and your Radio Triggers manual to ensure that you are shooting all your equipment at the correct sync speed. Finally the batteries within your Radio Triggers / Transceiver or flashgun are low on power and need replacing, or the batteries are incorrectly inserted, please check as necessary.

Q. My radio triggers fire the flash automatically?
A. If your flash / radio triggers start to fire the flash automatically then it is likely to be one or two things these are 1) Another Photographer is working in close proximity to you and he / she is using the exact same brand of radio triggers as you and are working on the exact same channel and group that you are working on. Switch to a new channel / group and the problem should stop. 2) Someone may be playing a game with you. Photographers have been known to play games on each other via pressing the “Test” button on Radio Triggers that they do know are compatible with other photographers radio sets. Look around you to see if you can see anyone having a giggle at your expense as the chances are it's another Photographer playing a game on you.
Q. Why do I need a Radio Trigger ?
A.

Wireless Radio Triggers are the next best thing since sliced bread with in the grounds of the photographic industry. Wireless radio triggers have revolutionized the way that us photographers now work with our lighting set ups both in the studio and outside the studio. For example photographers can now set their flash set ups into multiple groups, and switch in-between them, or even switch them off... etc... Back in the olden days then off camera flash was triggered simply just by a cable, which yes is still very reliable today but at the same time cables can also be very dangerous due to the fact that people can still just trip over the cables and hurt themselves. Not only that but cables also get tangled around people and studio equipment which at times can result in a very serious accident or seeing a very expensive bit of equipment being accidentally knocked over and broken.

This kind of scene was a major head ache for photographers in the olden days, but today we now have a varied range of wireless studio light triggers / transceivers on the market, some of which work on light (infra-red) and others work on radio frequencies. Radio Triggers are one of the most essential bits of equipment required for many studio photographers today.
