Flash Range-The Math
Each flash unit has a certain range of flash ability based on the total power it can produce. This means based on the manufacturers designation for that specific flash model, that you can blast light from the flash to a certain distance and achieve an acceptably exposed picture. Think back and you may remember; the higher the Guide Number the more flash output ability and the higher the flash output, the greater range or distance the flash can travel to your subject. Also, the lower the flash range the less distance the flash can send light and the pop-up flash is a great example of this.The content you are trying to access is only available to members. Sorry.
