Flowers In A Flash!

Light Up Flowers Using Flash.

Flowers light up any room. But it’s a challenge to get the right shot indoors. That’s when proper use of your flash and aperture can make all the difference. This Amaryllis photo shoot applies the right recipe of flash, ISO, aperture, and shutter speed to photograph flowers indoors.

Spotlighting An Amazing Amaryllis

An Amaryllis is one of the toughest flowers to photograph using flash, because the petals usually wash out in bright light. That’s when aperture becomes your new best friend.To get this tight close-up, I first shot at my fastest shutter speed using flash, which is 1/200th second. This avoids washout from shooting at a slower shutter speed like 1/60th second. I used a low ISO of 200 to reduce incoming light. Finally, I employed the master trick of “Over-aperturing” by shooting at f18.Over-aperturing is a Picturephant term based on experience. I’m a huge fan of getting maximum detail. Sometimes, that requires more narrow aperture than you would expect. When applied effectively, Over-aperturing can produce super photos.

Over-Aperturing For Great Detail

Here is what aperture and f stop mean. Like Venetian blinds, your aperture opens or closes your camera’s ability to take in light (exposure) and capture detail. The “f” in f stop refers to your focal length. It’s a fraction, so f8 means 1/8th open, while f13 means 1/13th open.

An f stop of f4 or even f8 is a wide aperture— which lets more light into your camera, but might not provide as much overall detail. An f stop of f13 or even f18 means a narrow aperture— which lets less light in, but provides more detail (also known as depth of field). Wider apertures produce brighter photos, while narrower apertures produce darker photos. But remember aperture is not the only way to control how much light your camera sees. You can alter brightness/darkness by pushing your ISO up (brighter) or down (darker).

Certainly, I was close enough to the Amaryllis to get detail with an aperture of f8 or f10. But by Over-aperturing (f18), combined with a low ISO and a maximum shutter speed using flash, I got super detail! This technique produces vibrant portraits of an Amaryllis. You see every line on each petal, yet still reveal that glittery sparkle of this gorgeous flower. While f18 could have produced a dark shot, I was so close to the Amaryllis at 105mm that my flash created plenty of light. I toned down that light both by using a low ISO and shooting with a fast shutter speed. I also captured the rich color of this Amaryllis.

By using the right recipe, I produced colorful and detailed photos which aren’t washed out. Flash and aperture can show off a flower’s true colors.

Photo Tips

Let your flowers do the talking by eliminating all the clutter of a background. Here, I used my trusty black blanket to totally contrast with the Amaryllis— which really sparkled from the flash!

Keep your ISO down when using flash. Lowering your ISO brings less light into your camera’s sensor. But remember, your flash will provide all the light you need.

If you have a pop-up flash, which fires automatically, follow this recipe of low ISO + fastest shutter speed using flash + Over-aperturing. It’s best to use Manual mode for the most control. But if you’re not used to shooting in Manual mode, use Aperture Priority mode, where you set the aperture, and your camera determines the shutter speed. Your camera’s shutter speed will be limited by your pop-up flash.

Experiment with your aperture. You might not have a big Mirrorless Full-frame Pro camera like mine, whose sensor takes in more light. For your camera, I suggest starting at f13, which allows more light in than f18.

Review & Refine! Keep checking your shots to see if your settings are good enough. The more you’re willing to improve your settings, the better a photographer you will be!
