Whole treatises can be written about the complicated interactions between light and photography. It is a world not enough appreciated by novice or hobbyist shooters, who may be used to relying on natural light to illuminate their sensors. But once you begin constructing your own lighting environments, you start to understand that flash photography is an art in and of itself. We can’t begin to account for the myriad purposes of flashes in this guide, but we can point you in the right direction. Here is a guide to some of the best flashes by camera type and level of expertise.
Best Budget Flash for All Cameras: YONGNUO YN560 IV Wireless Flash
If you’re somewhat new to flash photography and are on a tight budget, then the YONGNUO YN560-TX is probably worth looking into. Some shooters still prefer the proprietary realm of flash technology, but you’re pretty much guaranteed to spend a lot more money on those devices. For basic functionality—not to mention, wider compatibility—there’s the YONGNUO YN560 IV Wireless Flash. For less than $70, this package includes a built-in wireless trigger system, which allows you to use it as a flash speed light, as well as a flash controller transmitter. It’s relatively compact and lightweight, well built, versatile and rugged. It’s also pretty darn fast. Some users have complained about long-term reliability, and the lack of TTL (automatic, “through the lens”) may be a bit of a turn-off, but all that’s sort of something you have to expect for the budget price range.
