Lighting Ratios? But I Hate Math!

Guess what…I hate it too!
As a photographer, sooner or later someone is going to use the term “lighting ratio” with you in a conversation. Many hobbiests don’t even know what this term means. In fact, many seasoned photographers still don’t have much of a grasp of what a lighting ratio is.
A lighting ratio is simply the difference in light level between the key (main) light and the fill light. Lighting ratios really only take into account two lights: the key light and the fill light. Any other lights you use in the image are simply accent lights that aren’t taken into account.
Here’s the simple formula:
Power output of first light divided by the second light times 1.695. That's it! So as long as you always keep a calculator in your camera bag, you're all set.
Now if you’re still with me, just forget that last paragraph of horse poo.




Are you one of those photographers who has that one image that just completely defines you? The image you’re completely proud of and would die if anything ever happened to it? Sure, other images in your portfolio are great, but this one is special.
