How to make a silhouette in broad daylight

Believe it or not, this was taken in the early afternoon.

The steps are very easy and do not require a tripod nor stabilizer. You may want to use an active LCD display rather than a viewfinder.

1. Aperture: Leave it as however you'd like. I'd recommend something around than f/4 because we still want the foreground to be black. As long as the background has enough light and is color accurate, you can move on to step 2.

2. ISO: It's important that your ISO is nothing larger than 200. I would keep it at ISO 100 and change the f-stop accordingly. Essentially, you want the foreground's black to be a solid color. If your ISO is too high, then the camera's frame becomes too sensitive, and it will recognize the foreground really isn't black. If you shoot with a high ISO, you'll notice the foreground isn't a silhouette and the darker colors of the image have noise/grain on them. To sum it up, set your camera to ISO 100, and move on to step 3.

3. Shutter (why you don't need a tripod): If you've set up the last 2 steps and you still see the foreground in color, here's where it comes together. Your shutter speed should be really fast, as in 1/4000th second fast. Scroll through which shutter works best for your photo. You'll eventually notice that when the foreground becomes black and you increase the shutter speed, you won't visibly see the foreground become darker, increasing the shutters speed will only make the background darker.

4. Focus: Make sure your focus is set on the background. Some camera models adjust settings accordingly to make sure the color of what's in focus is on par with the actual color of the subject. Make sure your foreground isn't physically close to the camera (say 1-2 feet away) or else the foreground will become bokeh (blurred). You want to make sure the silhouette has a strong outline.

5. Exposure / White Balance (Your last resort): If all else fails, you can still override the color of the shot with these two. Lower your exposure and set your white balance to tungsten (the yellow room light). Hopefully, you've got the look you want. Happy shooting!
