2/12/2023 0 Comments Balancing flash and ambient lightJust don’t make the difference too glaringly obvious. Note that you don’t always have to match the flashes to ambient sometimes having a bit of temperature difference isn’t a bad thing, as it can help to highlight the subject. If it’s tungsten or fluorescent, you’ll need to use the correct gels over the front of the flash so they provide the same temperature color source as the ambient lighting you’ll also then have to set the white balance in-camera to match ambient. Note that flash power should be the last thing that’s altered (and done by the camera’s meter to balance out the required exposure) – this is because you are firstly setting your exposure based on ambient, then filling the primary subject with the precise amount of flash required for a proper exposure.Ĭolor is actually simpler: if it’s daylight, or close to it, there’s no need to gel your flashes, because they operate at fairly close to daylight Kelvin temperatures. ISO is the remaining balancing factor once you have set the other two – try and keep this low to maintain image quality, however. Aperture should allow you to hold in focus whatever you need to. Shutter speed should fall somewhere between your max sync speed and around 1/30s if you’re dealing with people higher if there are moving objects, lower if static. You’ve got three parameters to play with here – shutter speed, aperture and ISO. There’s no fixed rule for this, but the more ambient you want to preserve, the closer your exposure must be to ambient exposure the best way to do this is by shooting in manual mode and balancing out your shutter speed and aperture until you’re around one stop underexposed I wouldn’t do anything more than three stops of difference (unless you have very bright ambient point sources) because very little, if any, ambient sources will remain. The two major challenges with balancing ambient are exposure and color. All of the previous control points for single and multiple lights apply, of course. Today’s post focuses on how to do that.Īmbient light is your friend: it helps you to fill in the background with pre-lit object, providing compositional context but more importantly, you can use it to preserve the atmosphere of the scene, which can be difficult to recreate if you’re using 100% flash or strobe only. One of the neat things you can do when you’re controlling the light is highlighting your subject, but preserving the ambient atmosphere.
