Using Flash for Indoor Photography

aux flash

I have to admit it. Flash is my least favorite type of photography. I suppose since it seems so technical and the results can vary from situation to situation, looking artificial, too dark or too washed out. Luckily, today’s flashes can run pretty much on auto pilot and can be used for creative effect with just a little practice. But this time of year, and for the next four or five months, we’re all stuck indoors a great deal of the time, especially during the holiday season when we take so many candid photos at get-togethers. So I thought I’d share just a few basic flash tips to improve your indoor photos:

1) Your pop-up flash, the one that is part of the camera and pops up automatically if you are shooting in the “green box” total program mode, can cover just a short distance. Most of the time, any subject further than ten feet cannot get enough of the flash illumination for a properly exposed shot and that is why they look dark. You can boost your ISO to higher than normal (try 800 or 1000) to try and get more reach.

2) When you position your subject too close to a wall and use your pop-up flash, you are bound to get harsh shadows behind your subject. Eliminate this by having your subject step a few feet away from the wall and by shooting from a little bit above the subject (which is also a more flattering angle for portraits).

3) Your pop-up flash can cause red-eye quite often. This is because the flash is so close to the lens. It is worse on point-and-shoot cameras than DSLR cameras, but typical in either case. To eliminate red-eye, you can use the red-eye reduction function that throws out a pre-flash to make your subject’s eyes close down, but I find often that people think you’re done and move before the photo is actually shot. You can also try turning up the lights in the room to help the iris naturally close down a little.

4) If you are in a very dark room, the camera/flash may over-expose your subject (you know, the white face that appears to have nothing but eyes and lips) since the camera reads the room as very dark and wants to make it brighter. This also happens if you are too close to your subject. One solution is to back up to correct the latter, and turn up the room lights if you can for the former. If you cannot control the lighting, try moving your subject closer to a room light like I did above.

An on-camera auxiliary flash, like the one for my camera shown above, elevates the flash away from the lens and helps to reduce red-eye dramatically. This type of flash also helps in other ways: a) it can throw the flash further allowing you to be further away from your subject; and b) you can change the position of the flash to get more even lighting with much less shadows. This is called “bounce flash.”

The photo above of my very Thanksgiving-weary subject was taken with the auxiliary flash in a bounce position. The flash bounced off of the ceiling and back down onto my subject. You can see the lighting looks much more natural and softer than in either of the two photos below where the shots look more artificial and harsh. In the photos below, you can also see the harsh shadow under the lamp and on the futon frame. And, there are hot spots on her cheeks. You can also see how quickly the flash “drops off,” meaning the couch gets darker, whereas in the photo above, the couch and subject are all evenly illuminated since the bounced flash showers the whole area with light. One caution–always bounce off of a white wall or ceiling as the flash will take on the color cast of what it is being bounced off of (e.g., a green ceiling will produce a ghoulish effect).

Like learning how to control your depth of field to blur backgrounds, mastering your flash is a must for anyone who is looking to take better people photos. So this season, try to remember some of the tips above when shooting your flash candids at family gatherings. And if you can get an auxiliary flash made for your camera onto your wish list, it will be a worthwhile investment for many years.

Boost Your ISO and Take Photos Without Flash

Boost ISO ComparisonSometimes the best indoor photos are taken without flash. Natural lighting is, well, so much more natural. The photo on the left is taken at ISO 200 with my built-in flash. The colors are accurately represented. And the noise (grain) is tight and sharp. But compare it to the photo on the left. Look at how you can see the night light and almost read the numbers on the clock radio? You can even see the wood floor in the room. That’s because I did not use a flash and boosted my ISO considerably in order to get enough light to really make this photo work. I boosted the ISO all the way up to 1600. And the image is lit well because I used a very slow shutter speed, which allowed the ambient light in the room (the light in the shot, the light in the room behind me and the lights along the curtains) to record onto the CCD. The shot is certainly grainy, and the color is not as accurate as in the image on the left, but given a choice, I definitely prefer the right side. It has more dimension and life. Boosting your ISO makes the chip more sensitive to light, so you can shoot in lower light and still get the shot. In this case, my light level was so low, that even at ISO 1600 and with my aperture opened all of the way to let in the maximum amount of light through the lens, my shutter speed was very slow-just one quarter of a second (1/4). So I had my VC image stabilization feature on my lens switched on for this shot to be sure I could hand-hold the camera without getting blur.(Left: 18mm; F/9; 1/60th sec; ISO 200; flash fired. Right: 18mm; F/6.3; 1/4th sec; ISO 1600; no flash).

Father Daughter Portraits

DANCE PORTRAIT

I volunteered to take portraits for the Brownies Father Daughter Dance. Turned out to be 53 girls and their dads! Whew. So Angela volunteered as a second camera. We set-up a make-shift studio in the school hallway by tacking up a sheet and using just one on-camera flash. Not like a pro studio, for sure, but hey, this is the equipment most of us own. So with the father sitting in a chair, and his daughter sitting on one of his legs with her legs in the middle, we asked the dad to put his hands in his daughter’s lap and the girl to put her hands on dad’s. We asked them to put their heads together so there was no space in between. Lastly, we tried to make sure that his cheek was somewhere near her temple. This way, their heads were staggered, a key to good group portraits. You never want to have everyone lined up evenly as it makes for a boring picture. There were several cases where dad came with two daughters, so when adding in the third, fourth or fifth person, ask some stand behind or on the side of dad, as this will ensure all of their eyes are on different level s. And be sure to have all of them close the gaps and move in closer to dad to keep the subject area in the middle. Another trick: since we opened up the aperture all of the way to be sure to blur the background, make sure that no one leans too far forward or too far back as then one of them will not be in sharp focus. Then we stood far enough back (approx 8 feet) to make sure we did not get the floor in the photo and we zoomed in to fill the frame. The flash was bounced off the ceiling. I positioned the flash almost straight up and this eliminated shadows on the backdrop. However, the loss of light from traveling up to the ceiling back down to the subject made the photo appear under exposed, so we just moved the exposure compensation to +2 and the image looked great. Last tip? Iron the sheet! Overall, the portraits came out very nice and everyone seemed pleased. (Tamron 18-270mm VC with VC on, Nikon SB800 bounced flash, ISO 400, F5.6, 1/60th sec, +2 exposure compensation, Auto White Balance).
