Even if you have large windows, when it’s a dark cloudy day, you need extra reflectors to get enough light bouncing back onto the front of the food when you are using backlighting.
Backlighting is my favourite light direction for food because it makes the surface of food shiny which really makes a difference in photos. It refers to when you shoot with the light coming from behind the food ie. you are shooting from a 6 o’clock position, then the light is coming from around the 11 – 1 o’clock position. You can read more about backlighting and how it makes food look better in this post: How to Make Your Food Shine.
The main challenge that people tell me they face with backlighting is how to get enough light onto the front of the food (the direction you are shooting from) without the reflector getting in the way of the shot. And on a cloudy day, it’s just about as challenging as it gets!
So here’s how I set up a backlit shot on a cloudy day.
1. Use reflectors on 3 sides. You need extra reflectors on dark, cloudy days because there is less light so you need more “surface area” (so to speak!) for the light to bounce back from onto the food.
2. Position the reflectors on the left and right as close as you can to the front of the food without getting in the way of your lens. Basically, you just want to create the smallest gap you can to shoot “through”.
3. Use a low reflector directly in front of your camera. That way you can shoot over it. Make it as high as you can without it getting in the way! I use foam blocks which was the packing material for an appliance I got. They are perfect for using as reflectors because they are bright white AND they come in different sizes so you can stack them like lego and build different size “reflectors”!
4. Camera Settings – f/3.2, shutter speed 1/250, ISO 500. Note: I use a 50mm f/1.8 prime lens. Your settings will differ depending on the lens
5. Increase your ISO. The higher your ISO, the higher your shutter speed because your camera draws in more light. BUT you need to be mindful that the higher the ISO, the less sharp (i.e. more grainy) your photos will be. This is NOT a deal breaker for food bloggers where our images are only online but it does matter for when photos are used for high res purposes, like in print.
By default, I keep my ISO at 250 (i.e. lower = less grainy) and I only adjust it in lower light situations like this. I increased it to ISO 500 for this shot. I don’t like to go above ISO 750 as I find higher than this causes graininess in photos that I can see in photos on my blog. But that’s a personal thing and I do not discourage people from going higher than ISO 75o if that means being able to use a shutter speed fast enough so that the image isn’t blurry! (This is a key tip for people who don’t use a tripod).
The reflectors I use are all “homemade.” The right one is white foam cardboard. The one in front is foam blocks (2 stacked on top of each other – see point #3). And the one on the left is the box my Macbook came in! It’s really handy to use as a reflector because it stays upright on it’s side which means I can fit it in even when space is tight.
PS This set up shot was taken with an iPhone, so please excuse the quality!
You won’t need as many reflectors on a bright day! It will bounce so much light back onto the food, it will look like you’re using a flash! YES there is such think as too much light. It makes food photos look like “product shots”. i.e. so brightly illuminated on all sides you lose contours and shadows which help make the colours in food pop!
