You need to determine how much light you need to properly illuminate your typical subjects. It is not an issue to have too much light but low power can cause problems for you.

Recycle Rate

The flash you buy must have absolute basic features such as adjustable temperature, rotatable head, tilting angles, consistent color temperature, and so on.

Advanced Features

Therefore, you must ensure the flash has all the advanced features you need before buying it.

Adjustable Color Temperature
