| Food Photo Tips: Part 5 - Artificial Light
Hi again everyone. I'm back with another entry on how to use your digital camera for taking tabletop photos. Finding the right illumination for taking food photos after dark can be even more challenging than finding the right window for daylight photos and much has been written about it.
It is known that the larger the light source, the softer will be the shadows and conversely, the smaller and closer the light source, the sharper will be the shadows. So an ideal studio situation would be to have an illumination diffused enough so that it cast a flattering light without creating heavy shadows, used perhaps together with secondary lights and reflectors. Flash should never be used for food photos as it flattens the images so the result is most unattractive. But most of us have to cope with less than perfect conditions with over the counter strip lighting, lights in the stove exhaust hood, a lamp over the dining table or a small desk spot in a corner of the kitchen. This is an extensive subject which has turned into a large entry for today, so I'm going to separate it into paragraphs of different situations, showing how to cope with a certain type of lighting and equipment so you are able to digest it a bite at a time. 1. Worst Case Scenario - The Small Kitchen - One under-cupboard tube FLUORESCENT LIGHT: In this case, my tiny kitchen ...which has one old fashioned 8 watt fluorescent tube to illuminate the counter.
Above you see the improvised studio: a white cutting board placed behind, a white paper towel as reflector hanging over the paper roll, a piece of white foam as reflector left, and the subject placed on a white paper napkin draped over two cereal boxes. Took just a minute to set up, and it worked fine, considering the less than ideal setting. Here's the result:
Since indoor lighting is much weaker than daylight, the shutter speed of your camera will be slower, and the Scene settings such as Indoor, Candle and Available Light on your point & shoot will make that adjustment when you choose that scene. When the shutter stays open longer, any slight movement of the camera will cause a blurry photo. To put it simply, you really need a tripod when taking photos indoors after dark unless you can brace yourself and the camera so there isn't the slightest movement. To take this photo above in the weak light from the little 8 watt bulb I made several tries handholding the camera but without success, so I set up the tripod and was able to get a fairly decent photo.
The camera was set to Scene: INDOOR, White Balance (WB) set to FLUORESCENT 1 (that's the first of those centipedes on your WB menu), and the Exposure Value (EV) was raised to 0+.3....that's one notch up from 0.0. More details on settings for anyone who likes to know: Shutter speed 1/25s Aperture.f/4.2 .ISO 800. How are you doing so far? I hope you find it still easy to understand. 2. Overhead Lamp - TUNGSTEN - single 60 watt bulb
These are the incandescent light bulbs which are being phased out to be replaced by the new CFL (compact fluorescent lamp) bulbs which are much brighter at lower wattage and cooler temperatures.
In this case I just put the plate on a small side desk under the light, and set up reflectors on either side.....the right side with the old photo frame and a piece of white printer paper clipped to it and on the left side another piece of white paper taped to the bookend. I'm quite pleased with the result, although it could have been a little brighter if I had used the EV (Exposure Value) button to lighten the photo with a setting of +0.3.
The camera in the left photo was set to Scene: PORTRAIT, White Balance (WB): TUNGSTEN, with no EV +/-.
3. Overhead Lamp – FLUORESCENT 1 – 1 CFL bulb Here I changed the incandescent (tungsten) bulb for a new compact fluorescent bulb (CFL) at 11 watts in cool daylight colour.
Here is the picture that came from using that lamp, with the same setup as above in number 2, with reflectors either side.
The camera was set to Scene: PORTRAIT, White Balance (WB): FLUORESCENT 1, with no EV +/-.
4. Overhead Lamp and Small Spot – FLUORESCENT 1 – 2 CFL bulbs
Here is another setup on my desk, with a white paper sweep as backdrop , an overhead swivel desk lamp
I’ve used the first of the three fluorescent settings my camera offers. It’s a little warmer than the other two. This is what happens when you mistakenly use a TUNGSTEN setting for your White Balance (WB) instead of a FLUORESCENT setting (Remember the centipedes).
More about those CFL lamps:
You can see that the 15 watt bulb is rated as cool and it has a Kelvin value of 6400k.
If you need a warm fluorescent CFL for your house, look for a Kelvin rating around 3000k. Candlelight is rated at 1500k. The camera was set to Scene PORTRAIT, White Balance FLUORESCENT 1, with no EV +/-
5. Restaurants – Overhead Tungsten Lamp(s) + Candles You may have to look underneath the lamp to see if it’s a tungsten (incandescent) bulb or a CFL (fluorescent) but when it’s combined with candlelight for a cosy romantic setting you could wonder what setting to use on your camera without resorting to flash. I would go for the INDOOR Scene setting and then try looking through the viewfinder with the White Balance (WB) set at TUNGSTEN and if everything looks blue, then you know you have to switch the White Balance to a fluorescent setting.
The camera was set to INDOOR Scene, WB TUNGSTEN, with no EV +/-
If there is more candlelight than electric light, try the CANDLELIGHT setting as well. A look through the viewfinder before snapping the shutter will tell you if the
Another Restaurant Example: Overhead Tungsten Lamp :
Here there must have been more than one bulb in this quaint array of bottles but you can see the atmosphere, bright on the table and indirect light on the diners. I believe I set the scene to PORTRAIT, but it could also have been INDOOR, The White Balance (WB) was set to TUNGSTEN with no EV+/- change.
6. Candlelight
I didn’t have a tripod for this but I braced myself and stopped breathing for a moment (not a good thing to do on your birthday)
Well I hope you have enjoyed reading today's entry and have found it useful. If you have questions please post them here or send me a PM. :-) Next week I’ll show you how to make a mini light box and later we’ll make a full sized one. I have mine started but need some more materials from the craft shop.
So thanks for joining me. I'll be uploading the next installment soon. And please feel free to save the pages on your computer. Sharon (Canarybird) :-)

| I made a light box out of three sheets of foamcore. You can cut a hole in the top for your camera lens to go through so you can shoot from above. Fantastic tutorial, Sharon! Also, I've seen tricks to diffuse the light if you have a pop-up flash: you cut a small opening in the side of a plastic film canister and stick it over your flash mechanism on your camera. It produces much less harsh light that is more direct. You can also use a small piece of white foamcore to bounce the light to the ceiling. |

| Thanks Phyllis! Yes I have seen that idea as well as using a 5 gallon white plastic jug from laundry softener and cutting a hole, or a big white plastic basin. A lot of the success depends on the strength of the lamps you use outside to light up the inside of the container. And if you have a DSLR with a flash that can be tilted up towards the ceiling or behind, you can use an airline barf bag (excuse the term) slipped over the flash attachment to diffuse the light. I'm uploading these tutorials onto their own blog, at the rate one per week, with links to other interesting places and will also be adding some sections on using a DSLR: aperture and depth of field, understanding f stops, shutter speed, bracketing exposures and a little more.
